ARM: davinci: da850: do not specify clock_frequency for UART DT node
DT kernel on da850-evm comes up with garbled UART logs. This is because of mismatch in actual module clock rate and rate specified(clock-frequency) in DT blob. kernel should not assume or depend on bootloaders clock configuration, instead let it find the clock rate at runtime. Issue discussed here before arriving on this implementation: "ARM: davinci: da850 evm: update clock rate for UART 1/2 DT nodes" https://patchwork.kernel.org/patch/2162271/ Signed-off-by: Manjunathappa, Prakash <prakash.pm@ti.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>
