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 <redacted> --- arch/arm/boot/dts/da850.dtsi | 3 --- 1 files changed, 0 insertions(+), 3 deletions(-)
