From: Roger Tseng <rogerable@xxxxxxxxxxx> This patchset adds modules to support Realtek USB vendor specific class flash card reader: one base module in MFD subsystem and two host modules in both mmc and memstick subsystems. The architecture is similar to rtsx_pci. This work is done primarily to replace the staging driver: staging/rts5139, which doesn't utilize mmc nor memstick subsystems. Once the patchset or its revision is applied, we may need Greg's help to remove the staging one. v2: 1. Fix potential buffer overflow in rtsx_usb_seq_write_register() 2. Remove unnecessary casting and messages 3. Revise coding style and white spaces v3: 1. Fix MMC detection fail when under xhci 2. Minor change of pm_runtime behavior in rtsx_usb_ms to prevent some rare freeze due to erroneous Memstick card(not MS-Pro) 3. Further revise coding style as suggested in the thread of v2 4. Using managed resources: devm_* 5. Change license from "GPL v2 and later" to "GPL v2" v4: 1. Remove invocations to deprecated/removed mmc_suspend|resume_host APIs and unnecessary platform device pm routines 2. Support CRC-ignored R1 response for CMD13 in response to commit: a27fbf2f067b0cd6f172c8b696b9a44c58bfaa7a: mmc: add ignorance case for CMD13 CRC error 3. Remove unnecessary #ifdef CONFIG_PM_RUNTIME v5: 1. rtsx_usb_ms.c: adding header inclusion, removing unnecessary NULL checking, and add cancel_work_sync in removal handler to wait possible pending works. (Changes only rtsx_usb_ms. Other files remain the same to v4) v6: NOTE:since the v3 of patch 1/3 (rtsx_usb) has been merged, only diffs are submitted and splitted into two. 1. rtsx_usb.c: fix possible race conditions: rtsx_usb_bulk_transfer_sglist(): del_timer() => del_timer_sync() rtsx_usb_probe(): move setup_timer() before mfd_add_devices() and also remove unnecessary init_timer() 2. rtsx_usb.c: rtsx_usb_suspend(): add comments to LED turn-off (Changes only rtsx_usb.c. Other files remain the same to v5) Roger Tseng (4): [v6 fix] mfd/rtsx_usb: fix possible race condition [v6 fix] mfd/rtsx_usb: add comment in rtsx_usb_suspend mmc: Add realtek USB sdmmc host driver memstick: Add realtek USB memstick host driver drivers/memstick/host/Kconfig | 10 + drivers/memstick/host/Makefile | 1 + drivers/memstick/host/rtsx_usb_ms.c | 839 ++++++++++++++++++++ drivers/mfd/rtsx_usb.c | 14 +- drivers/mmc/host/Kconfig | 7 + drivers/mmc/host/Makefile | 1 + drivers/mmc/host/rtsx_usb_sdmmc.c | 1462 +++++++++++++++++++++++++++++++++++ 7 files changed, 2330 insertions(+), 4 deletions(-) create mode 100644 drivers/memstick/host/rtsx_usb_ms.c create mode 100644 drivers/mmc/host/rtsx_usb_sdmmc.c -- 1.8.2 -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
