During test campaign, and especially after several unbind/bind sequences, it has been seen that the SD-card on SDMMC1 thread could freeze. The freeze always appear on a CMD23 following a CMD19. Checking SDMMC internal registers shows that the tuning command (CMD19) has failed. The freeze is then due to the delay block involved in the tuning sequence. To correct this, clear the delay block register DLYB_CR register after the tuning commands. Signed-off-by:

The vendor driver implements special handling for multi-block SD_IO_RW_EXTENDED (and SD_IO_RW_DIRECT) commands which have data attached to them. It sets the MANUAL_STOP bit in the MESON_SDHC_MISC register for these commands. In all other cases this bit is cleared. Here we omit SD_IO_RW_DIRECT since that command never has any data attached to it. This fixes SDIO wifi using the brcmfmac driver which reported the following error without this change on a Netxeon S82 board using a Meson8 (S802) SoC: brcmf_fw_alloc_request: using brcm/brcmfmac43362-sdio for chip BCM43362/1 brcmf_sdiod_ramrw: membytes transfer failed brcmf_sdio_download_code_file: error -110 on writing 219557 membytes at 0x00000000 brcmf_sdio_download_firmware: dongle image file download failed And with this change: brcmf_fw_alloc_request: using brcm/brcmfmac43362-sdio for chip BCM43362/1 brcmf_c_process_clm_blob: no clm_blob available (err=-2), device may have limited channels available brcmf_c_preinit_dcmds: Firmware: BCM43362/1 wl0: Apr 22 2013 14:50:00 version 5.90.195.89.6 FWID 01-b30a427d Fixes: e4bf1b09 ("mmc: host: meson-mx-sdhc: new driver for the Amlogic Meson SDHC host") Signed-off-by:

It's seems prone to problems by allowing card detect and its corresponding mmc_rescan() work to run, during platform shutdown. For example, we may end up turning off the power while initializing a card, which potentially could damage it. To avoid this scenario, let's add ->shutdown_pre() callback for the mmc host class device and then turn of the card detect from there. Reported-by:

The size of the cache of register values is arch-dependant (PERF_REGS_MAX). This has the potential of causing an out-of-bounds access in the function "perf_reg_value" if the local architecture contains less registers than the one the perf.data file was recorded on. Since the maximum number of registers is bound by the bitmask "u64 cache_mask", and the size of the cache when running under x86 systems is 64 already, fix the size to 64 and add a range-check to the function "perf_reg_value" to prevent out-of-bounds access.

Initialize min_ratio if it is set during bdi unregistration. This can prevent problems that may occur a when bdi is removed without resetting min_ratio. For example. 1) insert external sdcard 2) set external sdcard's min_ratio 70 3) remove external sdcard without setting min_ratio 0 4) insert external sdcard 5) set external sdcard's min_ratio 70 << error occur(can't set) Because when an sdcard is removed, the present bdi_min_ratio value will remain. Currently, the only way to reset bdi_min_ratio is to reboot.
