2023-02-15mmc: meson-gx: remove meson_mmc_get_cdHeiner Kallweit1-15/+1
MMC core only checks whether return value of .get_cd() equals zero. Therefore -ENOSYS and 1 are effectively the same and the function can be removed.

2023-02-15mmc: moxart: set maximum request/block/segment sizesSergei Antonov1-0/+9
Per datasheet: maximum block length is 2048 bytes, data length field is in bits 0-23 of the Data Length Register. Also for DMA mode we have to take into account rx/tx buffers' sizes. In my tests this change doubles SD card I/O performance on big files. Before the change Linux used default request size of 4 KB.

If mmc_add_host() fails, it doesn't need to call mmc_remove_host(), or it will cause null-ptr-deref, because of deleting a not added device in mmc_remove_host().

2023-02-14mmc: sdio: fix possible resource leaks in some error pathsYang Yingliang2-15/+14
If sdio_add_func() or sdio_init_func() fails, sdio_remove_func() can not release the resources, because the sdio function is not presented in these two cases, it won't call of_node_put() or put_device(). To fix these leaks, make sdio_func_present() only control whether device_del() needs to be called or not, then always call of_node_put() and put_device(). In error case in sdio_init_func(), the reference of 'card->dev' is not get, to avoid redundant put in sdio_free_func_cis(), move the get_device() to sdio_alloc_func() and put_device() to sdio_release_func(), it can keep the get/put function be balanced. Without this patch, while doing fault inject test, it can get the following leak reports, after this fix, the leak is gone. unreferenced object 0xffff888112514000 (size 2048): comm "kworker/3:2", pid 65, jiffies 4294741614 (age 124.774s) hex dump (first 32 bytes): 00 e0 6f 12 81 88 ff ff 60 58 8d 06 81 88 ff ff ..o.....`X...... 10 40 51 12 81 88 ff ff 10 40 51 12 81 88 ff ff .@Q......@Q..... backtrace: [<000000009e5931da>] kmalloc_trace+0x21/0x110 [<000000002f839ccb>] mmc_alloc_card+0x38/0xb0 [mmc_core] [<0000000004adcbf6>] mmc_sdio_init_card+0xde/0x170 [mmc_core] [<000000007538fea0>] mmc_attach_sdio+0xcb/0x1b0 [mmc_core] [<00000000d4fdeba7>] mmc_rescan+0x54a/0x640 [mmc_core] unreferenced object 0xffff888112511000 (size 2048): comm "kworker/3:2", pid 65, jiffies 4294741623 (age 124.766s) hex dump (first 32 bytes): 00 40 51 12 81 88 ff ff e0 58 8d 06 81 88 ff ff .@Q......X...... 10 10 51 12 81 88 ff ff 10 10 51 12 81 88 ff ff ..Q.......Q..... backtrace: [<000000009e5931da>] kmalloc_trace+0x21/0x110 [<00000000fcbe706c>] sdio_alloc_func+0x35/0x100 [mmc_core] [<00000000c68f4b50>] mmc_attach_sdio.cold.18+0xb1/0x395 [mmc_core] [<00000000d4fdeba7>] mmc_rescan+0x54a/0x640 [mmc_core] Fixes: 3d10a1ba0d37 ("sdio: fix reference counting in sdio_remove_func()") Signed-off-by: Yang Yingliang <yangyingliang@huawei.com> Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20230130125808.3471254-1-yangyingliang@huawei.com Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

2023-01-27mmc: atmel-mci: fix race between stop command and start of next commandTobias Schramm1-3/+0
This commit fixes a race between completion of stop command and start of a new command. Previously the command ready interrupt was enabled before stop command was written to the command register. This caused the command ready interrupt to fire immediately since the CMDRDY flag is asserted constantly while there is no command in progress. Consequently the command state machine will immediately advance to the next state when the tasklet function is executed again, no matter actual completion state of the stop command. Thus a new command can then be dispatched immediately, interrupting and corrupting the stop command on the CMD line. Fix that by dropping the command ready interrupt enable before calling atmci_send_stop_cmd. atmci_send_stop_cmd does already enable the command ready interrupt, no further writes to ATMCI_IER are necessary.

SDHCI_QUIRK_MISSING_CAPS is not needed because __sdhci_read_caps() can be called instead. In preparation to get rid of SDHCI_QUIRK_MISSING_CAPS, replace SDHCI_QUIRK_MISSING_CAPS with __sdhci_read_caps(). __sdhci_read_caps() is also called from sdhci_setup_host() via sdhci_read_caps(), however only the first call to __sdhci_read_caps() does anything because after that host->read_caps has been set to true. Note, __sdhci_read_caps() does more than just set host->caps, such as do a reset, so calling __sdhci_read_caps() earlier could have unforeseen side-effects.

2023-01-23mmc: sdhci-esdhc-imx: only enable DAT[0] and CMD line auto tuning for SDIO deviceHaibo Chen1-0/+41
USDHC IP has one limitation: the tuning circuit can't handle the async sdio device interrupt correctly. When sdio device use 4 data lines, async sdio interrupt will use the shared DAT[1], if enable auto tuning circuit to check these 4 data lines, include the DAT[1], this circuit will detect this interrupt, take this as data on DAT[1], and adjust the delay cell wrongly, finally will cause the DATA/CMD CRC error. So for SDIO device, only enable DAT[0] and CMD line for auto tuning. To distinguish the card type during card init, involve init_card().
