Hi Alex,

Recently you used the_  __regmap__  _  support for at86rf230 driver.

I want to know about this framework.

I have few questions regarding this:

1.What is the objective of this framework ?
2. Where can we use it ?
3. I read that this for low speed protocols like SPI and I2C.
 Whether this is for slaves devices or master devices ?
4. Register of SPI or I2C controller devices already mapped to
processor address space. So in controller driver those registers
are accessed with read and write instructions.
What is the need of mapping the registers ?

5. Is there any material to get familiar with the framework ?


Thanks in advance.
