Merge tag 'davinci-for-v3.12/soc' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci into next/soc
From Sekhar Nori: DaVinci SoC updates for v3.12 ----------------------------- This set of SoC updates contains changes to the way UART clock is handled to enabled DT-boot to obtain UART clock frequency instead of relying on DT-binding being supplied. Similarly handling of MDIO clock is fixed to make it easier to support MDIO in DT-boot. Finally there is patch to remove now unnecessary setting of wake-up capable flag for RTC. * tag 'davinci-for-v3.12/soc' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci: ARM: davinci: fix clock lookup for mdio device ARM: davinci: da8xx: remove hard coding of rtc device wakeup ARM: davinci: serial: remove davinci_serial_setup_clk() ARM: davinci: serial: get rid of davinci_uart_config ARM: davinci: da8xx: remove da8xx_uart_clk_enable ARM: davinci: uart: move to devid based clk_get Signed-off-by: Kevin Hilman <khilman@linaro.org>
