On most of the Amlogic SoCs, the first UART controller in the "Everything-Else"
power domain has 128bytes of RX & TX FIFO, so add an optional property to describe
a different FIFO size from the other ports (64bytes).
This adds a property in the bindings, reads the property from the driver and updates
the DT with the new property.
Neil Armstrong (3):
dt-bindings: serial: amlogic,meson-uart: add amlogic,uart-fifosize
property
tty: serial: meson: retrieve port FIFO size from DT
arm64: dts: meson: set 128bytes FIFO size on uart A
