This series adds display drivers for rockchip and enables them on jerry, firefly-rk3288 (HDMI only) and rock2 (HDMI only). It builds on the recent keyboard series.
Driver are provided for video displays (EDP and HDMI) and the VOP (video output processor).
This series also adds several new uclasses: - PWM (Pulse-width modulation) - Panel (used for LCD panels) - Display (renamed from DisplayPort - a generic display with power, etc.) - Backlight (used for LCD backlights)
Since most of this implementation is device-tree-controlled it is fairly easy to enable HDMI on the other RK3288 devices. This series adds this for Firefly-RK3288. It also includes Radxa Rock 2 as a separate board since a device tree file is now available in Linux. HDMI is enabled on that board also.
There remain quite a few things still to do for core rockchip support. Here are a few noticed while preparing this series:
- Clocks / caches are not working correctly. The 'dhry' command shows approximately 60 DMIPS when supposedly running at 1.8GHz. Turning the cache on or off makes no difference. The platform should run at over 2000 DMIPS by my estimate. This problem is common on ARM platforms. For example I found:
beaver (Tegra) 818 DMIPS pit (Exynos) 276 DMIPS snow (Exynos) 521 DMIPS
- HDMI EDID-reading does not work on Jerry, perhaps because the clocks are not running as they should. It seems to work fine on other boards.
This series is available at u-boot-dm/rkd-working
