Subject: [PATCH v4 1/5] ARM: dts: sun8i: r40: add /omit-if-no-ref/ to pinmux nodes for UARTs 0&3
Date: Wed,  7 Apr 2021 14:14:24 +0300	[thread overview]
Message-ID: <20210407111428.3755684-2-i.uvarov@cognitivepilot.com> (raw)
In-Reply-To: <20210407111428.3755684-1-i.uvarov@cognitivepilot.com>

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.
