Subject: [PATCH v3 1/2] drm: rockchip/hdmi: add Innosilicon HDMI support
The Innosilicon HDMI is a low power HDMI 1.4 transmitter
IP, and it have been integrated on some rockchip CPUs
(like RK3036, RK312x).
Signed-off-by: Yakir Yang <ykk@...k-chips.com>
---
Changes in v3:
- Use encoder enable/disable function, and remove the encoder DPMS function
- Keep HDMI PLL power on in standby mode
Changes in v2:
- Using DRM atomic helper functions for connector init (Mark)
- Remove "hdmi->connector.encoder = encoder;" (Mark)
