      ARM: tegra: paz00: enable usb ports · 13db7a7f
      Marc Dietrich authored 
      This patch add support for the second and third ehci bus on paz00.
The first bus needs gadget and nvec support and will be added once
the needed patches are upstream.

      ARM: tegra: paz00: register i2c busses · dda9cd28
      Marc Dietrich authored 
      This adds support for the i2c busses on paz00. The 3rd bus is
reserved for the nvec, which acts as master and i2c-tegra has
not yet support for this kind of operation.
The sound codec (alc5632) is connected to the first bus and will
be added once the codec and glue driver is upstream.
The thermal sensor (atd7461) is connected to dvc as usual, but will
not be added now because i2c-tegra still misses probe support
(needs I2C_FUNC_SMBUS_EMUL).

      ARM: tegra: remove mach/barriers.h · 2b0aaaf1
      Colin Cross authored 
      The barriers implemented in arch/arm/mach-tegra/mach/barriers.h
are exactly the same as the default barriers implemented in
arch/arm/include/asm/system.h.  Remove barriers.h from Tegra,
and don't select ARCH_HAS_BARRIERS.

      ARM: Tegra: Seaboard: Re-order sdhci device registration · cfeb34ed
      Stephen Warren authored 
      Ensure the built-in eMMC is always named mmcblk0.

This is important because:

* U-Boot statically assigns MMC device IDs based on controller ID.
* U-Boot assumes that kernel MMC device ID numbering matches U-Boot numbering.
* U-Boot provides a kernel cmdline option e.g. root=/dev/mmcblk0p3 based on
  that numbering.
* The kernel dynamically assigns MMC device IDs based on enumeration order of
  the memory behind the host controller, rather than statically based on host
  controller ID like U-Boot.
* By registering the SDHCI controller for the built-in eMMC first, the
  enumeration of the built-in eMMC is performed first, and hence eMMC gets
  assigned ID 0 just like U-Boot. If the SD slot is filled, it then gets
  assigned ID 1 just like U-Boot.
* If the MMC IDs mismatch, and the system boots from SD card not eMMC, the
  kernel will access the eMMC instead of SD card when attempting to mount
  /dev/mmcblk1p3 as the root fs. If eMMC is not partitioned/formatted, the
  kernel will panic since the root fs can't be mounted. If eMMC is partitioned
  and formatted, the kernel will mount an unexpected filesystem as the root fs.

This change relies on the SDHCI driver performing initial card detection
synchronously during device registration. This is currently the case.
