From e327b3f564031a8d0090a6b3e3562a8b59bafe0e Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Fri, 19 Feb 2016 16:12:19 +0200 Subject: Revert "regulator: tps65217: remove tps65217.dtsi file" This reverts commit 8e6ebfaa9b384088002baa10f7534efa73a0794e. Without the patch reverted regulators will not work. This prevents MMC to be working for example so the boards can not boot to MMC rootfs. Tested it on beaglebone white and bisect also points to the reverted commit. The issue can be also fixed by adding "regulator-compatible =" to all board dts file for the regulators.
