It turns out that sc8180x (among others) doesn't have the same internal layout of the 4 subblocks. This series therefor modifies the binding to require all four regions to be described individually and then extends the driver to read these four regions. The driver will fall back to read the old single-reg format and apply the original offsets and sizes.
