According to the User's Manual Hardware, v1.50 Nov 20 2019,
the DRIF IP block M3-N (r8a77965) has a BITCTR register which
is not present on the H3 (r8a7795) or M3-W (r8a77995).
Does the DRIF IP block present on the M3-N (r8a77965) function
without support for this register in the driver?
If not then I think that:
1) This patch should be updated to note that renesas,rcar-gen3-drif
can only be used with H3 (r8a7795) and M3-W (r8a77995).
2) A driver patch is required
3) The DT patch, 2/2 of this series, should be updated to
i) Not use renesas,rcar-gen3-drif
ii) Extend the register aperture from 0x64 to 0x84.

Hi,
I'm wondering what the status of this patchset it.
