Subject: gpu: ipu-v3: Add CSI and SMFC module enable wrappers
X-Git-Tag: v4.14-rc1~7391^2~1^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3f5a8a946d860b9022a23bf1ed5ab76f6fdd7e6e;p=platform%2Fkernel%2Flinux-rpi.git

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.
