The original commit wasn't just about avoiding the bug (though that was a nice side effect). My understanding is that the SoC dtsi file ought to have most peripherals disabled by default and individual board dts files should enable the peripherals that they want. I think exynos5250 is particularly bad about this right now (it starts with most peripherals enabled) but that should probably be fixed... If my understanding is wrong, others on the list should definitely speak up! :) -Doug -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

The kernel dump produced by s3c-rtc driver as reported by commit 522ccdb6fd0e ("ARM: dts: Disable the RTC by default on exynos5") are no longer reproducible in latest kernel. Hence it would be good to re-enable RTC support for EXYNOS5250. Signed-off-by: Tushar Behera <tushar.behera@linaro.org> --- arch/arm/boot/dts/exynos5250.dtsi | 1 - 1 file changed, 1 deletion(-)
