From bcc6bd84d48cfc5f7b777feb2e2a6e264b270252 Mon Sep 17 00:00:00 2001 From: Jean-Jacques Hiblot Date: Tue, 30 Jan 2018 16:01:42 +0100 Subject: [PATCH] mmc: omap_hsmmc: allow the simple HS modes to use the default pinctrl The default configuration is usually working fine for the the HS modes. Don't enforce the presence of a dedicated pinmux for the HS modes.
