From c5075a1089e808d8f471ce21b02810cc98ab2692 Mon Sep 17 00:00:00 2001 From: Anton Vorontsov Date: Tue, 17 Mar 2009 00:13:54 +0300 Subject: sdhci: Add support for hosts reporting inverted write-protect state This patch adds SDHCI_QUIRK_INVERTED_WRITE_PROTECT quirk. When specified, the sdhci driver will invert WP state. p.s. Actually, the quirk is more board-specific than controller-specific.
