[PATCH v2 1/4] ARM: dts: sun8i: r40: add /omit-if-no-ref/ to pinmux nodes for UARTs 0&3

This patch adds the /omit-if-no-ref/ keyword to the pio nodes for UART0 and UART3 pins of the R40 SoC, which would reduce the fdt size on boards which do not use these UARTs. Signed-off-by: Ivan Uvarov <redacted> 1 file changed, 3 insertions(+)
