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...@ti.com> --- arch/arm/boot/dts/da850.dtsi | 3 --- 1 files changed, 0 insertions(+), 3 deletions(-) diff --git a/arch/arm/boot/dts/da850.dtsi b/arch/arm/boot/dts/da850.dtsi index 2c88313..4d43046 100644 --- a/arch/arm/boot/dts/da850.dtsi +++ b/arch/arm/boot/dts/da850.dtsi @@ -129,7 +129,6 @@ serial0: serial@1c42000 { compatible = "ns16550a"; reg = <0x42000 0x100>; - clock-frequency = <150000000>; reg-shift = <2>; interrupts = <25>; status = "disabled"; @@ -137,7 +136,6 @@ serial1: serial@1d0c000 { compatible = "ns16550a"; reg = <0x10c000 0x100>; - clock-frequency = <150000000>; reg-shift = <2>; interrupts = <53>; status = "disabled"; @@ -145,7 +143,6 @@ serial2: serial@1d0d000 { compatible = "ns16550a"; reg = <0x10d000 0x100>; - clock-frequency = <150000000>; reg-shift = <2>; interrupts = <61>; status = "disabled"; -- 1.7.4.1 _______________________________________________ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
