-Subject: [PATCH] drm/vc4: Start switching to using debugfs_reg32 helpers for
- debugfs.
-
-Every file was defining its own little struct and dumping for the
-regs, when there's a helper in debugfs for doing just this.  However,
-instead of printing:
-
-PV_HORZA (0x000c): 0x00000000
-
-we now print:
-
-PV_HORZA = 0x00000000
