Cool thanks. Yeah what you have can easily be combined with the patches
Balaji has posted to make HSMMC use drivers/mfd/syscon.c via regmap
for the SCM register access. Maybe take a look at the work in progress
patches in thread:

[PATCH v4 0/7] mmc: omap_hsmmc: pbias dt and cleanup

And also see my comments regarding using the SCM GENERAL register area
as base for the syscon.c driver. That should work for your driver too,
right? And then you can access the SYSCON1 register that way from your
consumer driver ;)
