Subject: [PATCH v4 07/17] phy: phy-rockchip-samsung-hdptx: Add support for eDP mode
Add basic support for RBR/HBR/HBR2 link rates, and the voltage swing and
pre-emphasis configurations of each link rate have been verified according
to the eDP 1.3 requirements.
Signed-off-by: Damon Ding <damon.ding@...k-chips.com>
---
Changes in v2:
- Add the module author
Changes in v3:
- Split this patch into two, one for correction and the other for
extension
Changes in v4:
- Add link_rate and lanes parameters in struct rk_hdptx_phy to store the
phy_configure() result for &phy_configure_opts.dp.link_rate and
&phy_configure_opts.dp.lanes
