Adding lcdif nodes to a power domain currently does work, it results in black/corrupted screens or hangs. While the driver does enable runtime pm it does not deal correctly with the block being unpowered. Changes since v3: * Don't set initial fb in mode_set_nofb, do it in crtc_enable * Simplify AXI clk handling to allow setting fb in crtc_enable * No functional changes Last 3 patches are identical to v3 with review tags attached.
