mmc: tegra: only use new clock/reset APIs

2016-09-27T16:11:03Z

Now that the standard clock/reset APIs are available for all Tegra SoCs, convert the MMC driver to use them exclusively, and remove any references to the custom Tegra-specific APIs. Cc: Jaehoon Chung Signed-off-by: Stephen Warren Signed-off-by: Tom Warren

mmc: tegra: Add DM_MMC support to Tegra MMC driver

2016-09-27T16:11:01Z

Convert the Tegra MMC driver to DM_MMC. Support for non-DM is removed to avoid ifdefs in the code. DM_MMC is now enabled for all Tegra builds. Cc: Jaehoon Chung Signed-off-by: Tom Warren (swarren, fixed some NULL pointer dereferences, removed extraneous changes, rebased on various other changes, removed non-DM support etc.) Signed-off-by: Stephen Warren

mmc: tegra: priv struct and naming cleanup

2016-09-27T16:11:01Z

struct mmc_host is a Tegra-specific structure, but the name implies it's something defined by core MMC code, which is confusing. Rename it to struct tegra_mmc_priv to make its purpose more obvious. The new name is also more appropriate for a DM driver private data structure, which will be relevant later in this series. Nothing needs access to this type except the MMC driver itself. Move the definition into the driver C file. Make sure all Tegra MMC functions are named tegra_mmc_*. Even though they're all static, it's useful to have good naming so that symbol tables are easy to interpret. A few functions aren't renamed by this patch since they'll be deleted by a subsequent patch in this series. Cc: Jaehoon Chung Signed-off-by: Stephen Warren Signed-off-by: Tom Warren

mmc: tegra: don't use periph_id in pad_init_mmc()

2016-09-27T16:11:01Z

The MMC driver will soon be converted to use standard clock/reset APIs, and so the periph_id field in the MMC device priv struct will disappear. Rework the implementation of pad_init_mmc() to rely on this; using the device register address is a much more direct test anyway.

mmc: tegra: move pad_init_mmc() into MMC driver

2016-09-27T16:11:01Z

pad_init_mmc() is performing an SoC-specific operation, using registers within the MMC controller. There's no reason to implement this code outside the MMC driver, so move it inside the driver. Cc: Jaehoon Chung Signed-off-by: Stephen Warren Signed-off-by: Tom Warren

mmc: tegra: use correct alias for SDHCI/MMC nodes

2016-09-27T16:11:01Z

The Tegra MMC driver currently honors "sdhci" entries in /aliases. The MMC core however uses "mmc" entries in /aliases. This difference will be relevant once the Tegra MMC driver is converted to DM, and the MMC core handles alias lookups. To avoid issues during that conversion, fix the Tegra MMC driver and all Tegra DTs to use the same alias name as the MMC core does.

mmc: squash lines for immediate return

2016-09-23T21:53:44Z

These functions can be much simpler by squashing lines for immediate return. For *_bind() callbacks, they will be a simple wrapper function of an upper-level bind API. For mmc_set_{boot_bus_width,part_conf}, they will be a wrapper of mmc_switch(). Signed-off-by: Masahiro Yamada Reviewed-by: Jaehoon Chung

mmc: dw_mmc: push/pop all FIFO data if any data request

2016-09-21T07:00:14Z

When DTO interrupt occurred, there are any remaining data still in FIFO due to RX FIFO threshold is larger than remaining data. It also causes that dwmmc didn't trigger RXDR interrupt, so is TX. It's responsibility of driver to read remaining bytes on seeing DTO interrupt. Signed-off-by: Jacob Chen Signed-off-by: Ziyuan Xu
