2016-12-04ARM: OMAP4+: Add support for getting pbias info from boardLokesh Vutla
Palmas driver assumes it is always TPS659xx regulator on all DRA7xx based boards to enable mmc regulator. This is not true always like in case of DRA71x-evm. So get this information based on the board.

2016-09-27mmc: tegra: priv struct and naming cleanupStephen Warren
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.
