From 42c1add97073b5a701b8aee0fdb69ef0345d4c50 Mon Sep 17 00:00:00 2001 From: Russell King Date: Fri, 28 Feb 2014 21:32:44 +0000 Subject: mmc: sdhci-spear: remove support for power gpio None of this code is currently used: there are no definitions of struct sdhci_plat_data in arch/arm, neither are there any DT properties which use card_power_gpio/power_active_high/power_always_enb. In any case, slot power control should be rigged up via vmmc and the regulator subsystem in the DT case.
