This patch series implements support for A83T DW HDMI and PHY. Contrary to v1 series, this one is based on latest linux-next, since all needed patches were merged.
While exactly this combination of HDMI controller and PHY is not common in Allwinner SoCs, this patch series nevertheless makes groundwork for other SoCs, which have same DW HDMI IP block, but different PHYs, like H3 and H5.
Please take a look.
Best regards, Jernej
Changes from v2: - Collected ACKs and Review-by tags - patch for deinit callback was replaced with the one which gives control of drvdata to driver - fixed meson driver (renamed reset function) - prototypes for newly exported functions in dw_hdmi.h were reordered
Changes from v1: - Collected ACKs - Separated bindings for controller and PHY - Split driver into two parts - controller and PHY - HDMI PHY driver now uses regmap for writes - added defines for PHY registers and bits - updated DT entries to accomodate new bindings - removed already merged clock patch - reworked first clock patch according to comments - added new clock patch which changes NKMP formula - split TCON patch in two, one for quirk and one for new compatible - reworked patch which exports DW HDMI PHY functions: - remove "gen2" from some function names - removed parameter from dw_hdmi_phy_reset() - added address parameter to dw_hdmi_phy_i2c_set_addr() - updated most of commit messages
