Inconsistent information between datasheet versions I'm afraid, and even between different registers in a single datasheet. We have DEFR0, DEFR1, and then DEFxR. I wonder if it's worth renaming the registers. > Regardless: > Reviewed-by: Geert Uytterhoeven> > > --- > > The patch is against David Airlie's 'linux.git' repo's 'drm-next' branch. > > > > drivers/gpu/drm/rcar-du/rcar_du_regs.h |5 +++-- > > 1 file changed, 3 insertions(+), 2 deletions(-) > > > > Index: linux/drivers/gpu/drm/rcar-du/rcar_du_regs.h > > === > > --- linux.orig/drivers/gpu/drm/rcar-du/rcar_du_regs.h > > +++ linux/drivers/gpu/drm/rcar-du/rcar_du_regs.h > > @@ -195,9 +195,10 @@ > > > > #define DEFR6_ODPM12_DISP (2 << 8) > > #define DEFR6_ODPM12_CDE (3 << 8) > > #define DEFR6_ODPM12_MASK (3 << 8) > > > > -#define DEFR6_TCNE2(1 << 6) > > +#define DEFR6_TCNE1(1 << 6) > > +#define DEFR6_TCNE0(1 << 4) > > > > #define DEFR6_MLOS1(1 << 2) > > > > -#define DEFR6_DEFAULT (DEFR6_CODE | DEFR6_TCNE2) > > +#define DEFR6_DEFAULT (DEFR6_CODE | DEFR6_TCNE1) -- Regards, Laurent Pinchart

Well, the R-Car M1A manual named it this way, hence is this name in the driver, I guess. > Care to update /DEFRx/DEFxR/ as well? No. :-) > Regardless: > Reviewed-by: Geert UytterhoevenThank you.

[PATCH] rcar-du: add/rename DEFR6 TCON bits
The TCNE2 bit of the DEFR6 register was renamed to TCNE1 in the R-Car gen2 manuals -- which makes more sense as that bit controls whether DU1, not DU2 is connected to TCON. While at it, add the TCNE0 bit which controls whether DU0 is connected to TCON. Based on the large patch by Andrey Gusakov .
