drm/bridge: anx7625: Ensure bridge is suspended in disable()
Similar to commit 26db46bc ("drm/bridge: parade-ps8640: Ensure bridge is suspended in .post_disable()"). Add a mutex to ensure that aux transfer won't race with atomic_disable by holding the PM reference and prevent the bridge from suspend. Also we need to use pm_runtime_put_sync_suspend() to suspend the bridge instead of idle with pm_runtime_put_sync(). Fixes: 3203e497 ("drm/bridge: anx7625: Synchronously run runtime suspend.") Fixes: adca62ec ("drm/bridge: anx7625: Support reading edid through aux channel") Signed-off-by:Hsin-Yi Wang <hsinyi@chromium.org> Tested-by:
