Hi all,
All Ethernet AVB instances on R-Car Gen4 SoCs have registers related to
UDP/IP support, starting at offset 0x800. However, the register blocks
for some (but not all) instances are too small to cover them.
This patch series fixes this by extending the register block sizes where
needed. Note that this has no immediate impact on actual operation, as
the Linux driver does not use the UDP/IP registers. Besides, ioremap()
granulatity is PAGE_SIZE, so the registers are accessible anyway.
I also considered introducing a new reg tuplet to cover the UDP/IP
registers. However, that would complicate handling as some instances
(on some R-Car Gen2/3 SoCs) already have two reg tuplets, and there are
no reg-names defined:
reg:
items:
- description: MAC register block
- description: Stream buffer
So I think just enlarging the first register block would be fine.
To be queued in renesas-devel for v6.9, if you agree.
Thanks for your comments!
