Hi Marc and everyone,

as requested I split the series into two parts. This is the first parts
with simple improvements to reduce the number of SPI transfers. The
second part will be the rest with coalescing support and more complex
optimizations.

Changes in v2:
- Fixed register ranges
- Added fixes: tag for two patches

Sorry that I am one day later than promised.

Best,
Markus
