From: Thierry Reding <[email protected]> The 1.2V supply for CSI and DSI was previously marked always-on. This is suboptimal because it prevents the supply from being disabled when there is no activity in the display or capture paths that it powers.
Hook up the regulator to the DSI output and mark it as not always-on, so that it will only be enabled when DSI actually needs it.
