Changes in v2: - Remove edp panel specific dt-binding entries. Only keep bridge specific entries (Sean Paul). - Remove custom-modes dt entry since its usage is removed from driver also (Sean Paul). - Remove is-pluggable dt entry since this will not be needed anymore (Sean Paul). Changes in v3: - Remove irq-gpio dt entry and instead populate is an interrupt property (Rob Herring). Changes in v4: - Add link to bridge chip datasheet (Stephen Boyd) - Add vpll and vcc regulator supply bindings (Stephen Boyd) - Add ref clk optional dt binding (Stephen Boyd) - Add gpio-controller optional dt binding (Stephen Boyd) Changes in v5: - Use clock property to specify the input refclk (Stephen Boyd). - Update gpio cell and pwm cell numbers (Stephen Boyd). Changes in v6: - Add property to mention the lane mapping scheme and polarity inversion (Stephen Boyd).
