From mboxrd@z Thu Jan 1 00:00:00 1970 From: tomasz.figa@gmail.com (Tomasz Figa) Date: Thu, 21 Jul 2011 14:57:51 +0200 Subject: [PATCH 3/4 v2] ARM: s3c64xx: Save/restore S3C64XX_MODEM_MIFPCON on suspend/resume to preserve LCD bypass state. Message-ID: To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
