From 1b53e3416dd05dd515d90ef8e587119da57328fe Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Mon, 27 Apr 2015 15:19:12 +0200 Subject: [PATCH] ARM: at91/dt: sama5d3 xplained: add fixed regulator for vmmc0 Add fixed regulator for vmmc0 and attach the vmmc for it to the mmc0 node on the SAM5D3 Xplained board. This will remove the following warning from the kernel: atmel_mci f0000000.mmc: No vmmc regulator found Note, atmel_defconfig will need fixed regulator support enabled if this is to be used properly.
