From 31e1391af210fdbf177966579a83d14e6a4cd828 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Tue, 24 Jul 2018 19:11:26 +0200 Subject: video: fbdev: pxafb: Add support for lcd-supply regulator Optionally obtain a lcd-supply regulator during probe and use it in __pxafb_lcd_power() to switch the power supply of LCD panels. This helps boards booted from DT to control such voltages without callbacks.
