Hi Martin,
Thank you for the patch! Yet something to improve:

The Meson8B SoC is using four ARM Cortex-A5 cores which come with a "TWD" (Timer-Watchdog) based timer. This adds support for the ARM TWD Timer on this SoC. Suggested-by: Carlo Caione <carlo@endlessm.com> [ rebased patch from Carlo, use IRQ_TYPE_EDGE_RISING instead of IRQ_TYPE_LEVEL_LOW to prevent "GIC: PPI13 is secure or misconfigured" message during boot, use pre-processor macros to specify the IRQ, added the correct clock, dropped TWD watchdog node since there's no driver for it anymore ] Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> --- arch/arm/boot/dts/meson8b.dtsi | 7 +++++++ 1 file changed, 7 insertions(+)
