Merge tag 'davinci-for-v3.12/dt' of git://git.kernel.org/pub/scm/linu…

…x/kernel/git/nsekhar/linux-davinci into next/soc From Sekhar Nori: DaVinci DT updates for v3.12 ---------------------------- This set of patches add ethernet DT nodes for DA850 and also remove now unneeded specification of UART clock frequency so kernel can now boot irrespective of what the bootloader setting of UART frequency is. * tag 'davinci-for-v3.12/dt' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci: ARM: davinci: da850: do not specify clock_frequency for UART DT node ARM: davinci: da850: add DT node for ethernet ARM: davinci: da850: add OF_DEV_AUXDATA entry for davinci_emac ARM: davinci: da850: add OF_DEV_AUXDATA entry for mdio. ARM: davinci: da850: add DT node for mdio device Signed-off-by: Kevin Hilman <[email protected]>
