Subject: [PATCH 3/4 v2] ARM: s3c64xx: Save/restore S3C64XX_MODEM_MIFPCON on suspend/resume to preserve LCD bypass state.
Date: Thu, 21 Jul 2011 14:57:51 +0200	[thread overview]
Message-ID: <mailman.95.1313970596.20020.linux-arm-kernel@lists.infradead.org> (raw)

This patch makes sure that the LCD bypass state is preserved during sleep mode.
It achieves this by saving the S3C64XX_MODEM_MIFPCON register, which is not
handled by any other code currently.
