From 74ff81e16c3275a7d0fd4137c8f2279b7a491810 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 12 Nov 2018 15:12:35 +0100 Subject: mmc: sdhci: imx: Use the slot GPIO descriptor Simplify things by making the i.MX SDHCI driver just use slot GPIO with descriptors instead of passing around the global GPIO numbers that we want to get rid of. As it turns out, just one single board is using the platform data to pass in GPIOs numbers for CD and WP, so we augment this to use a machine descriptor table instead.
