Merge tag 'tegra-cleanups' of git://git.kernel.org/pub/scm/linux/kernel/git/olof/tegra into tegra/cleanups
Minor fixes that weren't urgent enough to go into 3.3. The two paz00 patches are in mainline already but got merged after the branch point for this branch, so they're duplicated. I also ended up merging in rmk/for-armsoc into this later on to fix a bug introduced by it, so it's included but it's not the base of this branch. * tag 'tegra-cleanups' of git://git.kernel.org/pub/scm/linux/kernel/git/olof/tegra: ARM: tegra: Enable CPUIdle on Tegra20 ARM: tegra: export usb phy symbols ARM: tegra: build localtimer support only when needed ARM: tegra: select CPU_FREQ_TABLE ARM: tegra: select required CPU and L2 errata options ARM: tegra: paz00: fix wrong UART port on mini-pcie plug ARM: tegra: paz00: fix wrong SD1 power gpio Signed-off-by: Arnd Bergmann <arnd@arndb.de>
