Subject: [PATCH 0/5] phy: rockchip: phy-rockchip-inno-csidphy: add support
 for rk3588 variant

Habidere,

The Rockchip RK3588 features two MIPI CSI-2 DPHYs (not to be confused with
the two combo MIPI DSI/CSI CPHY/DPHY blocks). The CSI-2 DPHYs can be
supported using the existing phy-rockchip-inno-csidphy driver, the notable
differences being
 - the control bits in the GRF
 - the additional reset line
This patch series adds support for this variant.

As you may have guessed, this is part of the efforts to bring the support
for the RK3588 Video Capture (VICAP) unit mainline.

Looking forward to your comments!
