Hi,
the intention of this series is to extend use of the demuxer for I2C
on the lager, koelsch, porter, koelsch, alt and silk boards cover all I2C IP
blocks that are either already used or exposed via an EXIO connector.
* This is based on work by Wolfram Sang.
* Testing:
- Underlying driver problems are discussed in the thread
"[PATCH v2 0/4] ARM: dts: r8a7790: lager: use demuxer for I2C"
- I have only compile tested the silk and porters patches as I do
not have access to those boards
- For all other boards I have boot tested the code and the
the default settings seem to work.
* This series is based on renesas-next-20160621-v4.7-rc1
* To aid review it is provided in git at:
git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git topic/i2c-demu x-v3
* I also intend to add demux for I2C for r8a7792/blanche
Changes between v2 and v3
* Group extra GPIO buses
* Add GPIO fallback for IIC1/I2C1 on Lager
* Add patches for koelsch, porter, alt and silk
Changes between v1 and v2
* Provide GPIO fallback for I2C2,
this does not seem appropriate for other I2C blocks on the lager board
