mmc: dw_mmc: Remove the public dw_mmc header file

2017-02-13T12:19:59Z

There are currently no external users of the public dw_mmc header file, except the dw_mmc driver itself. Therefore let's move the definitions from the public dw_mmc header file into the existing private dw_mmc header file and then remove the public one.

This patch removed the meaningless value. Instead, use the cookie's enum values for executing correctly. Signed-off-by: Jaehoon Chung Tested-by: Heiko Stuebner Signed-off-by: Ulf Hansson

mmc: dw_mmc: add reset support to dwmmc host controller

2016-09-26T19:31:19Z

Dwmmc host controller may in unknown state when entering kernel boot. One example is when booting from eMMC, bootloader need initialize MMC host controller into some state so it can read. In order to make sure MMC host controller in a clean initial state, this reset support is added. With this patch, a 'resets' property can be added into dw_mmc device tree node. The hardware logic is: dwmmc host controller IP receives a reset signal from a 'reset provider' (eg. power management unit). The 'resets' property points to this reset signal. So, during dwmmc driver probe, it can use this signal to reset itself. Refer to [1] for more information.

mmc: dw_mmc: remove the quirks flags

Remove the quirks flag. (DW_MCI_QUIRK_BROKEN_DTO) For removing this, enabled the dto_timer by defaults. It doesn't see any I/O performance degression. In future, dwmmc controller should not use the quirks flag. Signed-off-by: Jaehoon Chung Reviewed-by: Shawn Lin Signed-off-by: Ulf Hansson

dw_mmc already use mmc_of_parse to get "broken-cd" property, but it considered "broken-cd" to be a quirk in its driver. We don't need this quirk here, and just take what we need from mmc->caps.

mmc: dw_mmc: use resource_size_t to store physical address

2015-12-22T10:32:19Z

The dw_mmc driver stores the physical address of the MMIO registers in a pointer, which requires the use of type casts, and is actually broken if anyone ever has this device on a 32-bit SoC in registers above 4GB. Gcc warns about this possibility when the driver is built with ARM LPAE enabled: mmc/host/dw_mmc.c: In function 'dw_mci_edmac_start_dma': mmc/host/dw_mmc.c:702:17: warning: cast from pointer to integer of different size cfg.dst_addr = (dma_addr_t)(host->phy_regs + fifo_offset); ^ mmc/host/dw_mmc-pltfm.c: In function 'dw_mci_pltfm_register': mmc/host/dw_mmc-pltfm.c:63:19: warning: cast to pointer from integer of different size host->phy_regs = (void *)(regs->start); This changes the code to use resource_size_t, which gets rid of the warning, the bug and the useless casts.
