Subject: [U-Boot] [PATCH v2 2/2] mx25pdk: Turn on the LCD supply
Date: Sat, 21 Feb 2015 17:22:50 -0200	[thread overview]
Message-ID: <1424546570-14083-2-git-send-email-festevam@gmail.com> (raw)
In-Reply-To: <1424546570-14083-1-git-send-email-festevam@gmail.com>

From: Fabio Estevam <fabio.estevam@freescale.com>

Currently there is no support for MC34704 PMIC in the mainline kernel.

Turn on the LCD supply via bootloader for the time being, so that we could 
use the LCD in the kernel.
