mmc: mediatek: Drop pointer to mmc_host from msdc_host

2020-09-24T12:28:40Z

The MediaTek MMC driver uses pointer to get from private msdc_host structure to the generic mmc_host structure. However mmc_host always precedes msdc_host in memory so compute its address with a subtraction (which is cheaper than a dereference) using mmc_from_priv() and drop the extra pointer.

mmc: Set PROBE_PREFER_ASYNCHRONOUS for drivers that existed in v4.4

2020-09-07T12:20:17Z

This is like commit 3d3451124f3d ("mmc: sdhci-msm: Prefer asynchronous probe") but applied to a whole pile of drivers. This batch converts the drivers that appeared to be around in the v4.4 timeframe.

mmc: mediatek: add pre_enable() and post_disable() hook function

2020-09-07T07:11:31Z

CQHCI_ENABLE bit in CQHCI_CFG should be disabled after msdc_cqe_disable(), and should be enabled before msdc_ceq_enable() for MTK platform. Add hook functions for cqhci_host_ops->pre_enable() and cqhci_host_ops->post_disable().

mmc: mediatek: add optional module reset property

2020-08-24T07:39:53Z

This patch fixs eMMC-Access on mt7622/Bpi-64. Before we got these Errors on mounting eMMC ion R64: [ 48.664925] blk_update_request: I/O error, dev mmcblk0, sector 204800 op 0x1:(WRITE) flags 0x800 phys_seg 1 prio class 0 [ 48.676019] Buffer I/O error on dev mmcblk0p1, logical block 0, lost sync page write This patch adds a optional reset management for msdc. Sometimes the bootloader does not bring msdc register to default state, so need reset the msdc controller.

mmc: mediatek: make function msdc_cqe_disable() static

The sparse tool complains as follows: drivers/mmc/host/mtk-sd.c:2269:6: warning: symbol 'msdc_cqe_disable' was not declared. Should it be static? This function is not used outside of mtk-sd.c, so this commit marks it static.

mmc: mediatek: command queue support

2020-07-24T10:53:33Z

Support command queue for mt6779 platform. a. Add msdc_set_busy_timeout() to calculate emmc write timeout. b. Connect mtk msdc driver to cqhci driver through host->cq_host->ops = &msdc_cmdq_ops; c. msdc_cmdq_irq() will link up with cqchi_irq(). Besides, it provides more irq error messages like RSPCRCERR/CMDTO/DATACRCERR/DATTMO. d.

mmc: mtk-sd: Demote msdc_recheck_sdio_irq() function header

No other function in the file is documented using kerneldoc and no effort to document the function arguments have been made. It's a bit of an oddity to say the least. Let's downgrade it from kerneldoc to a standard comment block instead.
