From 4ccaf5ddeb04a7c0ef4f31ce5705a2635606fd72 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Mon, 10 Nov 2014 17:38:19 -0200 Subject: [PATCH] mx53loco: Change 'fdt_file' dynamically Since kernel 3.15 there are two dtb's for the imx53-qsb board: imx53-qsb.dtb - For the boards with DA9053 PMIC imx53-qsrb.dtb - For the boards with MC34708 PMIC Change the 'fdt_file' dynamically, so that the correct dtb can be used depending on the board variant.
