Subject: ARM: dts: Add clocks to the Gemini SoC
X-Git-Tag: v4.13-rc1~168^2~27^2
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=664ed4e283926d753e876a1347b7729135a3f6b8;p=karo-tx-linux.git

ARM: dts: Add clocks to the Gemini SoC

We have a clock controller for the Gemini SoC, so make use of the
driver and add clocks to the peripherals. Remove the hard-coded
frequency from the UART and add switch the timer compatible to the
generic that uses the clock framework for clock speed look-up.
