From 3f5a8a946d860b9022a23bf1ed5ab76f6fdd7e6e Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Tue, 22 May 2012 17:08:48 +0200 Subject: gpu: ipu-v3: Add CSI and SMFC module enable wrappers IPU_CONF_..._EN bits are implementation details, not to be made public. Add wrappers around ipu_module_enable/disable, so the CSI V4L2 driver can enable/disable the CSI and SMFC modules.
