[U-Boot] [PATCH v3 0/6] Tegra30: MMC: Add DT-based MMC driver for Tegra30/Cardhu

This patchset adds SDMMC device-tree support to the Tegra30 dts files,
and enables the Tegra MMC driver on Tegra30 Cardhu.

I've tested this on my Cardhu-A04 and everything works fine,
including card detect. All Tegra boards also build w/o error, and
Seaboard MMC functionality is unchanged.

Changes in v2:
- Use mmc_id instead of base address in pad_init_mmc
- Remove all TEGRA_SDMMCx_BASE defines, no longer used
- Add/use compatible entry for Tegra30 SDMMC driver
Changes in v3:
- Remove GP SDIO pad cfg writes - done in pinmux/padctrl init tables

Tom Warren (6):
  Tegra30: fdt: Add SDMMC (sdhci) nodes for T30 boards (Cardhu for now)
  Tegra: MMC: Added/update SDMMC registers/base addresses for T20/T30
  Tegra30: MMC: Add SD bus power-rail and SDMMC pad init routines
  mmc: Tegra: Add SD bus power/voltage function and MMC pad init call.
  Tegra30: mmc: Add Tegra30 SDMMC compatible entry to fdtdec & driver
  Tegra30: MMC: Enable DT MMC driver support for Tegra30 Cardhu boards
