From 2398c41d64321e62af54424fd399964f3d48cdc2 Mon Sep 17 00:00:00 2001 From: "H. Nikolaus Schaller" hns@goldelico.com Date: Thu, 7 Nov 2019 11:30:39 +0100 Subject: [PATCH] omap: pdata-quirks: remove openpandora quirks for mmc3 and wl1251

With a wl1251 child node of mmc3 in the device tree decoded in omap_hsmmc.c to handle special wl1251 initialization, we do no longer need to instantiate the mmc3 through pdata quirks.

We also can remove the wlan regulator and reset/interrupt definitions and do them through device tree.
