Re: [PATCH 2/2] drm: rcar-du: Add HDMI outputs to R8A7796 device description

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Laurent,

This looks good to me.

Table 35.1 (in the DU datasheet) certainly shows that there is only an HDMI-IF0
on the M3, but it's amusing that (and I was confused by the fact that) my
r8a7796 board (Salvator-X) still has the HDMI1 populated. Of course I presume
this is populated to keep the boards the same but is not connected in the chip.

Anyway, that's irrelevant to this patch so ...
