gpu: ipu-v3: Implement use counter for ipu_dc_enable(), ipu_dc_disable() The functions ipu_dc_enable() and ipu_dc_disable() enable/disable the DC globally in the IPU_CONF register, but the DC is used by multiple clients on different DC channels. So make sure to only disable/enable the DC globally based on a use counter. Signed-off-by: Steve Longerbeam <steve_longerbeam@mentor.com> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
