* mmc: tegra: Add DM_MMC support to Tegra MMC driverTom Warren2016-09-27-208/+69
| | | | | | | | | | | 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 <jh80.chung@samsung.com> Signed-off-by: Tom Warren <twarren@nvidia.com> (swarren, fixed some NULL pointer dereferences, removed extraneous changes, rebased on various other changes, removed non-DM support etc.) Signed-off-by: Stephen Warren <swarren@nvidia.com>
* mmc: tegra: priv struct and naming cleanupStephen Warren2016-09-27-138/+161
| | | | | | | | | | | | | | | | | | | | 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.

* mmc: tegra: don't use periph_id in pad_init_mmc()Stephen Warren2016-09-27-4/+3
| | | | | | | | | | | 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 driverStephen Warren2016-09-27-0/+28
| | | | | | | | | | 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.

* mmc: tegra: use correct alias for SDHCI/MMC nodesStephen Warren2016-09-27-5/+5
| | | | | | | | | | | | | | | 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.
