One usecase for these callbacks is that on certain platforms it is neccessary to configure a gpio pin as pwm pin. On these platforms it is usefull to have the added callbacks, so that the gpio pin can be configured at the same time as the pwm device.

This patch adds S3C2410_BOARD_NR_IRQS which specifies the number of extra board IRQs. Board specific code would use S3C2410_BOARD_IRQ_START to get the number of it's first irq. Since it is possible to support a multiple boards with a single kernel and there is no easy way to set a CONFIG option to multiple values and only use the maximum each board which needs board IRQs has do be explicitly added to irqs.h Signed-off-by: Lars-Peter Clausen --- arch/arm/mach-s3c2410/include/mach/irqs.h | 22 ++++++++++++++++++++-- 1 files changed, 20 insertions(+), 2 deletions(-) diff --git a/arch/arm/mach-s3c2410/include/mach/irqs.h b/arch/arm/mach-s3c2410/include/mach/irqs.h index 6c12c63..04c59ab 100644 --- a/arch/arm/mach-s3c2410/include/mach/irqs.h +++ b/arch/arm/mach-s3c2410/include/mach/irqs.h @@ -153,9 +153,9 @@ #define IRQ_S3C2443_AC97 S3C2410_IRQSUB(28) #ifdef CONFIG_CPU_S3C2443 -#define NR_IRQS (IRQ_S3C2443_AC97+1) +#define S3C2410_NR_INTERNAL_IRQS (IRQ_S3C2443_AC97+1) #else -#define NR_IRQS (IRQ_S3C2440_AC97+1) +#define S3C2410_NR_INTERNAL_IRQS (IRQ_S3C2440_AC97+1) #endif /* compatibility define. */ @@ -173,4 +173,22 @@ /* Our FIQs are routable from IRQ_EINT0 to IRQ_ADCPARENT */ #define FIQ_START IRQ_EINT0 +/* Board specific IRQs + * If your board needs a extra set of IRQ numbers add it to the list here. + * Make sure that the numbers are kept in descending order, so if support for + * multiple boards is compiled in the maximum will be used and there are enough + * IRQ numbers available for each board. + */ + +#if 0 +/* Number of board specific irqs go here */ +#else +#define IRQ_BOARD_NR 0 +#endif + +#define IRQ_BOARD_START S3C2410_NR_INTERNAL_IRQS +#define IRQ_BOARD_END (IRQ_BOARD_START + IRQ_BOARD_NR) + +#define NR_IRQS IRQ_BOARD_END + #endif /* __ASM_ARCH_IRQ_H */ commit 8dd3b11c092dff5aa3892c1e12cbda799fd37891 s3c board irq Author: Lars-Peter Clausen Date: Sun Oct 11 01:23:35 2009 +0200 s3c24xx: Add number of board irqs for the gta02 The gta02 uses the glamo mfd driver which requires 9 board irqs and the pcf50633 mfd driver which requires 40 irqs.

At least a good amount of ping torture didn't make them come back so far. The issue is that, if there are several back-to-back packets, sometimes no interrupt is generated for one of them. This seems to be caused by the mysterious dual packet mode, which the USB hardware enters automatically if the endpoint size is half that of the FIFO. (On the 2440, this is the normal situation for bulk data endpoints.) There is also a timing factor in this. I think what happens is that the USB hardware automatically sends an acknowledgement if there is only one packet in the FIFO (the FIFO has space for two). If another packet arrives before the host has retrieved and acknowledged the previous one, no interrupt is generated for that second one. However, there may be an indication. There is one undocumented bit (none of the 244x manuals document it), OUT_CRS1_REG[1], that seems to be set suspiciously often when this condition occurs. There is also CLR_DATA_TOGGLE, OUT_CRS1_REG[7], which may have a function related to this. (The Samsung manual is rather terse on that, as usual.) This needs to be examined further. For now, the patch seems to do the trick. Note that this is not a clean solution by any means, because we might potentially get stuck in that interrupt for quite a while. --- drivers/usb/gadget/s3c2410_udc.c | 3 +++ 1 files changed, 3 insertions(+), 0 deletions(-) diff --git a/drivers/usb/gadget/s3c2410_udc.c b/drivers/usb/gadget/s3c2410_udc.c index d5f4c1d..e6b76d8 100644 --- a/drivers/usb/gadget/s3c2410_udc.c +++ b/drivers/usb/gadget/s3c2410_udc.c @@ -842,6 +842,7 @@ static void s3c2410_udc_handle_ep(struct s3c2410_ep *ep) u32 ep_csr1; u32 idx; +handle_ep_again: if (likely (!list_empty(&ep->queue))) req = list_entry(ep->queue.next, struct s3c2410_request, queue); @@ -881,6 +882,8 @@ static void s3c2410_udc_handle_ep(struct s3c2410_ep *ep) if ((ep_csr1 & S3C2410_UDC_OCSR1_PKTRDY) && req) { s3c2410_udc_read_fifo(ep,req); + if (s3c2410_udc_fifo_count_out()) + goto handle_ep_again; } } } commit 4b5493b4c126b54a730d57a619ede97424ad0e7c gpio bank J (needs rewrite) Author: Lars-Peter Clausen Date: Tue Nov 3 00:29:53 2009 +0100 s3c: Register gpio bank J with gpiolib This is nonportable and wastes a lot of memory and thus should be replaced with a prober solution asap. --- arch/arm/mach-s3c2410/include/mach/gpio.h | 5 +++-- arch/arm/plat-s3c24xx/gpiolib.c | 13 +++++++++++-- 2 files changed, 14 insertions(+), 4 deletions(-) diff --git a/arch/arm/mach-s3c2410/include/mach/gpio.h b/arch/arm/mach-s3c2410/include/mach/gpio.h index 15f0b3e..0b53cad 100644 --- a/arch/arm/mach-s3c2410/include/mach/gpio.h +++ b/arch/arm/mach-s3c2410/include/mach/gpio.h @@ -20,10 +20,11 @@ * devices that need GPIO. */ -#define ARCH_NR_GPIOS (256 + CONFIG_S3C24XX_GPIO_EXTRA) +#define ARCH_NR_GPIOS (512 + CONFIG_S3C24XX_GPIO_EXTRA) #include #include #include +#include -#define S3C_GPIO_END (S3C2410_GPIO_BANKH + 32) +#define S3C_GPIO_END (S3C2440_GPIO_BANKJ + 32) diff --git a/arch/arm/plat-s3c24xx/gpiolib.c b/arch/arm/plat-s3c24xx/gpiolib.c index 4f0f11a..c0b0366 100644 --- a/arch/arm/plat-s3c24xx/gpiolib.c +++ b/arch/arm/plat-s3c24xx/gpiolib.c @@ -26,6 +26,7 @@ #include #include +#include static int s3c24xx_gpiolib_banka_input(struct gpio_chip *chip, unsigned offset) { @@ -160,8 +161,16 @@ struct s3c_gpio_chip s3c24xx_gpios[] = { .label = "GPIOH", .ngpio = 11, }, - }, -}; + }, { + .base = S3C2440_GPJCON, + .pm = __gpio_pm(&s3c_gpio_pm_2bit), + .chip = { + .base = S3C2440_GPJ0, + .owner = THIS_MODULE, + .label = "GPIOJ", + .ngpio = 11, + }, + },}; static __init int s3c24xx_gpiolib_init(void) { commit 6e279858214c5929aaf45e7eb454720ebd482294 debug disable messages Author: Lars-Peter Clausen Date: Thu Nov 5 23:04:42 2009 +0100 S3C: Allow to completly disable low-level messages In some cases it is desirable to completly disable low-level messages.

Although the external interrupts support level and edge triggered irqs their handler is currently always set to handle_edge_irq(). While being technically wrong for a level triggered irq to be handled by handle_edge_irq() it will cause serious problems in combination with a oneshot irq. handle_edge_irq() will unmask the irq immediately and as a result the irq will be triggered again before the threaded irq handler had a chance to run and clear the irq source. Thus level triggered irqs should be handled by handle_level_irq. According to the specs the irq controller will remember if an irq has been triggered while it had been masked and will issue it when the irq gets unmasked. Thus it is sufficient to use handle_level_irq() for edge triggered irqs as well. Hence handle_level_irq() can always be used for external interrupts.

The header + file include/wmi.h contains all command and event manifest constants as + well as structure typedefs for each set of command and reply parameters. + +Data Frames + + The data payload transmitted and received by the target follows RFC-1042 + encapsulation and thus starts with an 802.2-style LLC-SNAP header. The + WLAN module completes 802.11 encapsulation of the payload, including the + MAC header, FCS, and WLAN security related fields. At the interface to the + message transport (HTC), a data frame is encapsulated in a WMI message. + +WMI Message Structure + + The WMI protocol leverages an 802.3-style Ethernet header in communicating + the source and destination information between the host and the AR6000 + modules using a 14-byte 802.3 header ahead of the 802.2-style payload. In + addition, the WMI protocol adds a header to all data messages: + + { + INT8 rssi + The RSSI of the received packet and its units are shown in db above the + noise floor, and the noise floor is shown in dbm. + UINT8 info + Contains information on message type and user priority. Message type + differentiates between a data packet and a synchronization message. + } WMI_DATA_HDR + + User priority contains the 802.1d user priority info from host to target. Host + software translates the host Ethernet format to 802.3 format prior to Tx and + 802.3 format to host format in the Rx direction. The host does not transmit the + FCS that follows the data. MsgType differentiates between a regular data + packet (msgType=0) and a synchronization message (msgType=1). + +Data Endpoints + + The AR6000 chipset provides several data endpoints to support quality of + service (QoS) and maintains separate queues and separate DMA engines for + each data endpoint. A data endpoint can be bi-directional. + + Best effort (BE) class traffic uses the default data endpoint (2). The host can + establish up to two additional data endpoints for other traffic classes. Once + such a data endpoint is established, it sends and receives corresponding QoS + traffic in a manner similar to the default data endpoint. + + If QoS is desired over the interconnect, host software must classify each data + packet and place it on the appropriate data endpoint. The information + required to classify data is generally available in-band as an 802.1p/q style + tag or as the ToS field in the IP header. The information may also be available + out-of-band depending on the host DDI. + +Connection States + + Table B-1 describes the AR6000 WLAN connection states: + + Table B-1. AR6000 Connection States + +Connection State + Description + + DISCONNECTED + In this state, the AR6000 device is not connected to a wireless + network. The device is in this state after reset when it sends the + WIRELESS MODULE “READY” EVENT, after it processes a + DISCONNECT command, and when it loses its link with the + access point (AP) that it was connected to. The device signals a + transition to the DISCONNECTED state with a “DISCONNECT” + event. + +CONNECTED + In this state, the AR6000 device is connected to wireless networks. + The device enters this state after successfully processing a + CONNECT, which establishes a connection with a wireless + network. The device signals a transition to the CONNECTED state + with a “CONNECT” event. + + +Message Types + + WMI uses commands, replies, and events for the control and configuration of + the AR6000 device. The control protocol is asynchronous. Table B-2 describes + AR6000 message types: + +Table B-2. AR6000 Message Types + +Message Type + Description + +Commands + Control messages that flow from the host to the device + +Replies/Events + Control messages that flow from the device to the host. + + The device issues a reply to some WMI commands, but not to others. + The payload in a reply is command-specific, and some commands do + not trigger a reply message at all. Events are control messages issued + by the device to signal the occurrence of an asynchronous event. + + +WMI Message Format + + All WMI control commands, replies and events use the header format: + + WMI_CMD_HDR Header Format + { + UINT16 id + This 16-bit constant identifies which WMI command the host is issuing, + which command the target is replying to, or which event has occurred. + WMI_CMD_HDR + } + + + A variable-size command-, reply-, or event-specific payload follows the + header. Over the interconnect, all fields in control messages (including + WMI_CMD_HDR and the command specific payload) use 32-bit little Endian + byte ordering and fields are packed. The AR6000 device always executes + commands in order, and the host may send multiple commands without + waiting for previous commands to complete. A majority of commands are + processed to completion once received. Other commands trigger a longer + duration activity whose completion is signaled to the host through an event. + +Command Restrictions + + Some commands may only be issued when the AR6000 device is in a certain + state. The host is required to wait for an event signaling a state transition + before such a command can be issued. For example, if a command requires + the device to be in the CONNECTED state, then the host is required to wait + for a “CONNECT” event before it issues that command. + + The device ignores any commands inappropriate for its current state. If the + command triggers a reply, the device generates an error reply. Otherwise, the + device silently ignores the inappropriate command. + +Command and Data Synchronization + + WMI provides a mechanism for a host to advise the device of necessary + synchronization between commands and data. The device implements + synchronization; no implicit synchronization exists between endpoints. + + The host controls synchronization using the “SYNCHRONIZE” command + over the control channel and synchronization messages over data channels. + The device stops each data channel upon receiving a synchronization message + on that channel, processing all data packets received prior to that message. + After the device receives synchronization messages for each data endpoint + and the “SYNCHRONIZE” command, it resumes all channels. + + When the host must guarantee a command executes before processing new + data packets, it first issues the command, then issues the “SYNCHRONIZE” + command and sends synchronization messages on data channels. When the + host must guarantee the device has processed all old data packets before a + processing a new command, it issues a “SYNCHRONIZE” command and + synchronization messages on all data channels, then issues the desired + command. + + + +WMI Commands + + ADD_BAD_AP + Cause the AR6000 device to avoid a particular AP + ADD_CIPHER_KEY + Add or replace any of the four AR6000 encryption keys + ADD_WOW_PATTERN + Used to add a pattern to the WoW pattern list + CLR_RSSI_SNR + Clear the current calculated RSSI and SNR value + CONNECT_CMD + Request that the AR6000 device establish a wireless connection + with the specified SSID + CREATE_PSTREAM + Create prioritized data endpoint between the host and device + DELETE_BAD_AP + Clear an entry in the bad AP table + DELETE_CIPHER_KEY + Delete a previously added cipher key + DELETE_PSTREAM + Delete a prioritized data endpoint + DELETE_WOW_PATTERN + Remove a pre-specified pattern from the WoW pattern list + EXTENSION + WMI message interface command + GET_BIT_RATE + Retrieve rate most recently used by the AR6000 + GET_CHANNEL_LIST + Retrieve list of channels used by the AR6000 + GET_FIXRATES + Retrieves the rate-mask set via the SET_FIXRATES command. + GET_PMKID_LIST_CMD + Retrieve the firmware list of PMKIDs + GET_ROAM_DATA + Internal use for data collection;
