Subject: [PATCH] ARM: dts: sun8i: Add SPI controller node in H3
Date: Wed, 19 Oct 2016 22:46:08 +0900 [thread overview]
Message-ID: <20161019134608.12850-1-woogyom.kim@gmail.com> (raw)
H3 supports two SPI controllers. Four pins (MOSI, MISO, SCLK, SS) are
configured through the pinctrl subsystem. It is almost same as A31 SPI
except buffer size, so those DT properties are reusable.
