X-Git-Tag: v6.6.17~5843^2~29^2~27
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=eb2d64bfcc174919a921295a5327b99a3b8f4166;p=platform%2Fkernel%2Flinux-rpi.git

drm: xlnx: zynqmp_dpsub: Report HPD through the bridge

Now that the driver uses the connector bridge helper, HPD can be
reported directly for the connector through the drm_bridge_hpd_notify()
function.
