SubjectRe: [PATCH v2 0/5] arm64: dts: rockchip: support mail and IPA thermal for rk3399
From
Date
Hi Rob & Heiko,

Do we have the chance to merge these patches?

I'm try to bring up the display and run webgl for testing with my github on
https://github.com/Caesar-github/rockchip/commits/gru/next-stable-chromeos

I believe the Rocky@RK will post patches to support the other SoCs after.
