Nit: Can you call it DM365_OSD_BASE. If we were to include REG in the
name, then it should be done consistently. So we would instead have
DM365_KEYSCAN_REG_BASE.

This expression does not make much sense. It is same as BIT(5). You
needed a mask and an enable?

	.end   = DM365_OSD_REG_BASE + 0xff,

A similar fix is needed multiple places below. Sorry, I did not notice
this last time around.

Agreed its equivalent to BIT(5), but pll2c2sysclk5 depends on two bits
bit 5 and bit bit 6, so to keep consistent I used them. Do you want me to remove
it and just keep BIT(5) ?
