Thanks for your patch!

I had a deeper look, as the name "B0WI" (with zero) is also present
in drivers/pinctrl/renesas/pinctrl-rza2.c, and because Section 41.4.2
("Operation for Peripheral Function") in the RZ/G2L Group Hardware
User's Manual does talk about the "B0WI" (with zero) bit.

Apparently Rev. 0.51 of the RZ/A2M Group Hardware User's Manual used
both variants. Later (Rev. 1.00) revisions replaced the O-based
variant by the zero-based variant. So it looks like "B0WI" (with
zero) is correct, and the RZ/G2L, RZ/V2L, RZ/G2UL, and RZ/Five HW
manuals should be fixed instead. The RZ/G3S manual already uses
the correct naming.

when I'm talking to journalists I just say "programmer" or something like that.
