-Subject: [PATCH] drm/panel/raspberrypi-touchscreen: Insert more delays.
-
-This avoids failures in cases where the panel is enabled
-or re-probed very soon after being disabled or probed.
-These can occur because the Atmel device can mis-behave
-over I2C for a few ms after any write to the POWERON register.
