From 5dbdd3a600906f56a19c9a82a741705988851a28 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 31 Oct 2018 20:34:51 +0100 Subject: [PATCH] pinctrl: renesas: Add POCCTRL handling to r8a77990 Add definition of the POCCTRL register and bits therein to R8A77990 E3 pincontrol driver. This allows the pincontrol driver to configure SDHI pin voltage according to power-source DT property.
