This adds a property in the bindings, reads the property from the driver and updates the DT with the new property. Changes since v1: - switched to a more generic "fifo-size" Neil Armstrong (3): dt-bindings: serial: amlogic,meson-uart: add fifo-size property tty: serial: meson: retrieve port FIFO size from DT arm64: dts: meson: set 128bytes FIFO size on uart A .../devicetree/bindings/serial/amlogic,meson-uart.yaml | 6 ++++++ arch/arm64/boot/dts/amlogic/meson-axg.dtsi | 1 + arch/arm64/boot/dts/amlogic/meson-g12-common.dtsi | 1 + arch/arm64/boot/dts/amlogic/meson-gx.dtsi | 1 + drivers/tty/serial/meson_uart.c | 5 ++++- 5 files changed, 13 insertions(+), 1 deletion(-) -- 2.25.1
