R8A7791_CLK_RCAN is changed?
Yes. It shouldn't be?
All definitions in include/dt-bindings/ are part of the DT ABI, and cannot be
changed without breaking the DT binding.
Hence when adding new entries, they must be added at the end of the list,
using a new available value.
Oh, OK...
Apart from that, what happens if you boot a new DTS on a kernel with an old
clk-rcar-gen2 driver that doesn't know about the new CPG clock?
Does it just fail to initialize and find that single clock,
Yes, exactly. The driver will cuss loudly but will continue to work.
or does the whole CPG driver fail?
No.
I wanted to check that after seeing the RCAN CPG patch, but haven't gotten to it
yet due to Xmas and NY holidays.
No holidays yet here. There will be long holidays starting from January 1st...
