Subject: [PATCH v2 1/3] ARM: dts: rockchip: rv1108-elgin: Fix vcc5/6-supply representation
Date: Thu, 31 Jan 2019 10:47:07 -0200 [thread overview]
Message-ID: <20190131124710.30238-1-otavio@ossystems.com.br> (raw)
On rv1108-elgin-r1 board the RK805 VCC5 and VCC6 supplies come from
the BUCK2 regulator at 2.2V, so fix the representation in the
device tree.
While at it, rename it from vdd_cam to vdd_buck2, which is a better
name for the regulator label.
