Add the HDMI controller (bridge) driver for the StarFive JH7110. This driver binds to the starfive,jh7110-inno-hdmi-controller node. It gets its register access, module and bus clocks from voutcrg, and consumes the pixel clock and the PHY from its hdmi_phy sibling. The driver calls the generic inno_hdmi_probe function, which picks up the regmap shared with the PHY from the parent device and registers a DRM bridge. The .enable hook is responsible for setting the PHY's pixel clock rate via clk_set_rate() and powering on the PHY via phy_power_on(). The DC8200 has two panels, each exposing a DP and a DPI interface, and a mux in the video output system controller picks which of them drives the HDMI transmitter. It comes out of reset on panel 0 / DPI, which happens [ ... ] devm_drm_bridge_add(). Releasing them in .remove runs before devres unwinds and would leave the bridge registered with its clocks already gated. Signed-off-by: Michal Wilczynski <m.wilczynski@samsung.com>
