From 03190a7888493058c3a0fd6c50fd0b8dadd165ee Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Wed, 5 Sep 2018 04:11:08 -0500 Subject: mmc: omap_hsmmc: Fix pbias for omap3_logic to enable CD pin The MMC card detect pin is connected to gpio127 on omap3_logic. When setting up the pbias register for MMC, let's also enable gpio_127 for the card detect. As part of the package deal, gpio_126 and gpio_129 are also enabled.
