[PATCH 1/2] ARM: dts: rockchip: add cpu and gpu regulators to rk3288-evb-act8846

[Heiko Stübner]

The evaluation board using the act8846 as main pmic uses two additional
regulators to provide the cpu and gpu voltage. Add these and also add
the link to cpu supply from vdd_cpu.

[PATCH 2/2] ARM: dts: rockchip: housekeeping off i2c0 on rk3288-evb boards

[Heiko Stübner]

Use the same transfer speed on both the rk808 and act8846 variants and
remove the status=okay from the rk808 one which is already set in the
shared rk3288-evb.dtsi .
