Allwinner A64 has display engine pipeline like other Allwinner SOC's A83T/H3/H5. A64 behaviour similar to Allwinner A83T where Mixer0 => TCON0 => LVDS/RGB/MIPI-DSI Mixer1 => TCON1 => HDMI as per Display System Block Diagram from Allwinner_A64_User_Manual_V1.1.pdf This is third patch-set followed with previous RFC[1], first and second series[2][3] and merely concentrated on HDMI pipeline through TCON1 and rest will add eventually. This series fixed previous version comments - Rebasing on linux-next - sqash all pipeline components in one patch - Enable all pipeline components in board dts - about documenting fallback compatibles - adding new compatible for mixer1 Log: [ 1.450984] Jagan: sun8i_mixer_probe [ 1.464981] sun4i-drm display-engine: bound 1200000.mixer (ops sun8i_mixer_ops) [ 1.472572] sun4i-drm display-engine: bound 1c0d000.lcd-controller (ops sun4i_tcon_ops) [ 1.480676] sun8i-dw-hdmi 1ee0000.hdmi: Linked as a consumer to regulator.10 [ 1.488738] sun8i-dw-hdmi 1ee0000.hdmi: Detected HDMI TX controller v1.32a with HDCP (sun8i_dw_hdmi_phy) [ 1.498879] sun8i-dw-hdmi 1ee0000.hdmi: registered DesignWare HDMI I2C bus driver [ 1.507372] sun4i-drm display-engine: bound 1ee0000.hdmi (ops sun8i_dw_hdmi_ops) [ 1.514778] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
