* spi: prefix modalias with "spi:"Anton Vorontsov2009-09-231-0/+1
| | | | | | | | | | | | | | | | | | | | | This makes it consistent with other buses (platform, i2c, vio, ...). I'm not sure why we use the prefixes, but there must be a reason. This was easy enough to do it, and I did it.

* libertas: Add support for Marvell Libertas CF8305Marek Vasut2009-08-281-2/+37
| | | | | | | | | | | | | The CF8305 is a very old silicon running firmware version 3.0 . This card also needs some special treatment as it's so old it can't do unaligned register access. But since that happens only at one place, there were no changes made to the register access functions, but instead that particular place was fixed. Also, this card uses only one-stage firmware which is loaded the same way as helper firmware. The second-stage firmware isn't loaded on this card and doesn't therefore have to be supplied.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SDIO driver sets the surpriseremoved flag before calling lbs_remove_card. With IEEE PS enabled, lbs_remove_card must issue a command to exit IEEE PS mode, however with that flag set the command path is blocked and the card is never taken out of IEEE PS mode. This step is required to ensure that the driver can be reloaded. This patch moves the setting of surpriseremoved after lbs_remove_card is called. Tested with V9 firmware by ensuring that IEEE PS is disabled when the driver is removed. Reloading the driver is not fully tested due to a separate issue with module reload in the SDIO driver, however this patch at least leaves the card in a better state when we bring the driver down.

* | libertas: correct card cleanup order in SPI driverAndrey Yurovsky2009-07-101-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SPI driver does a couple of card cleanup steps in the wrong order on module removal. If IEEE PS is enabled, this results in the card being left in IEEE PS mode and subsequent failures to reload the module. The problem is that the surpriseremoved flag is set before calling lbs_remove_card, but that function needs to issue a command to exit IEEE PS mode (the flag blocks the command path). In addition, lbs_stop_card should be called first because it clears out any pending commands. Tested on a GSPI device with V9 firmware by confirming that we can reload the module with or without IEEE PS enabled. Also fix a warning from the wrong uint format in a printk.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Libertas currently maintains a copy of the WPA unicast and group keys when using WPA or WPA2. This copy is checked when deciding whether or not to return to sleep in IEEE PS mode but the actual copying back to priv was omitted, which breaks IEEE PS mode with WPA/WPA2 when one issues commands that require temporarily keeping the device awake. This patch introduces the omitted copy-back of the keys so that IEEE PS functions correctly in WPA/WPA2 mode. Thanks to Dan Williams for clearing up the issue. V2: fix typo.

| | | | | | | | | | | | | | | | | | | | | | | This patch is to incorporate Dan Williams' comments for commit: "libertas: implement function init/shutdown commands for SD8688" 1. remove fn_init_required and fn_shutdown_required variables from lbs_private structure. If required, __lbs_cmd() will be called directly to send function init/shutdown command for SD8688 in if_sdio_probe() or if_sdio_remove() callback. 2. add global variable "user_rmmod" to distinguish between the module removal case and the card removal case. This flag will be checked in if_sdio_remove() against SD8688 card to determine whether or not the function shutdown command needs to be sent. 3. remove "card" from if_sdio_model structure as it cannot store card pointers for multiple cards. Besides, it's no longer needed to store the "card" pointer with changes #1 & #2 above. Signed-off-by: Bing Zhao <bzhao@marvell.com> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.

* libertas: get SD8688 rx length with one CMD52Bing Zhao2009-05-222-2/+58
| | | | | | | | | | | | | | | | Usually, the 16-bit rx length is read from scratch pad registers with two CMD52 transactions: SD8385: IF_SDIO_SCRATCH_OLD (0x80fe/0x80ff) SD8686/SD8688: IF_SDIO_SCRATCH (0x34/0x35) Alternatively, SD8688 firmware offers an enhanced method for driver to read an 8-bit rx length (in units) with a single CMD52: IF_SDIO_RX_UNIT 0x43 is read one time after firmware is ready. IF_SDIO_RX_LEN 0x42 is read every time when rx interrupt is received. Signed-off-by: Bing Zhao <bzhao@marvell.com> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.

* libertas: fix GSPI card event handlingandrey@cozybit.com2009-05-221-0/+7
| | | | | | | | | | | The GPSI interface driver does not re-enable the Card Event Interrupt, which causes problems after a card event (for example: link-loss) comes in. This can lead, for example, to the card failing to re-associate. This patch ensures that we re-enable the Card Event Interrupt when we handle card events.

* libertas: add support for Marvell SD8688 chipBing Zhao2009-04-223-11/+23
| | | | | | | | | | | | | | | | | | | | | | | | | libertas: add support for Marvell SD8688 chip Use RxPD->pkt_ptr to locate eth803 header in the packet received since SD8688/v10 firmware allows a gap between RxPD and eth803 header. Set SDIO block size to 256 for CMD53. The maximum block size for SD8688 WLAN function is set to 512 in TPLFE_MAX_BLK_SIZE. But using 512 as block size results upto 2K bytes data (4 blocks) being transferred and causes buffer overflow in firmware. Both changes above are backward compatible with earlier firmware versions for SD8385/SD8686. The SDIO_DEVICE_IDs for SD8688 chip are added in include/linux/mmc/sdio_ids.h Signed-off-by: Kiran Divekar <dkiran@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.

* libertas: increase spi driver thread priorityAnna Neal2009-04-221-0/+4
| | | | | | | | | | | | | | Currently, the libertas main thread contends with the spi driver thread in the TX path. To improve throughput, ensure that the driver thread has higher scheduling priority than the libertas main thread. Do this by making the libertas spi driver thread a low priority real time thread. We measured an average throughput improvement of 13%. Signed-off-by: Anna Neal <anna@cozybit.com> Signed-off-by: Andrey Yurovsky <andrey@cozybit.com> Signed-off-by: John W.
