Subject: freedreno,ir3: rename Z_CLAMP_ENABLE to Z_CLIP_DISABLE
X-Git-Tag: upstream/22.3.5~6736
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6cb41c51884c2488194f74e2ce637b950c835620;p=platform%2Fupstream%2Fmesa.git

freedreno,ir3: rename Z_CLAMP_ENABLE to Z_CLIP_DISABLE

UNK5 of GRAS_CL_CNTL is still unclear though.
