So, here is the newest series for using the I2C demuxer on Gen2 boards. Initially done by Simon. The intention of this series is to extend use of the demuxer for I2C on the lager, koelsch, porter, koelsch, alt and silk boards to cover all I2C IP blocks that are either already used or exposed via an EXIO connector. I tested this on a Lager board where I could successfully switch between I2C, IIC, and GPIO on I2C2. Simon, can you test with your script on the other boards? If all works, I'll pick up the i2c patch for 4.9, so the DTS changes should be fine for 4.10. The branch is here: git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/ip-switch-rework Regards, Wolfram Changes between v4 and v3 * rebased to latest renesas-drivers (double checked that the moved i2c clients were complete because they changed meanwhile) * fixed the aliases to be proper phandles * fixed some typos in comments and commit messages * added a patch to ensure i2c-gpio works again 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 Simon Horman (13): ARM: dts: lager: rename and reindex i2cexio ARM: dts: lager: use demuxer for IIC1/I2C1 ARM: dts: lager: use demuxer for IIC2/I2C2 ARM: dts: lager: use demuxer for IIC3/I2C3 ARM: dts: koelsch: use demuxer for I2C1 ARM: dts: koelsch: use demuxer for I2C2 ARM: dts: koelsch: use demuxer for I2C4 ARM: dts: porter: use demuxer for I2C2 ARM: dts: gose: use demuxer for I2C2 ARM: dts: gose: use demuxer for I2C4 ARM: dts: alt: use demuxer for I2C1 ARM: dts: alt: use demuxer for I2C4 ARM: dts: silk: use demuxer for I2C1 Wolfram Sang (1): i2c: mux: demux-pinctrl: make drivers with no pinctrl work again arch/arm/boot/dts/r8a7790-lager.dts | 329 ++++++++++++++++++++++------------ arch/arm/boot/dts/r8a7791-koelsch.dts | 263 ++++++++++++++++++--------- arch/arm/boot/dts/r8a7791-porter.dts | 129 +++++++------ arch/arm/boot/dts/r8a7793-gose.dts | 203 +++++++++++++-------- arch/arm/boot/dts/r8a7794-alt.dts | 86 +++++++-- arch/arm/boot/dts/r8a7794-silk.dts | 129 +++++++------ drivers/i2c/muxes/i2c-demux-pinctrl.c | 22 ++- 7 files changed, 765 insertions(+), 396 deletions(-) -- 2.9.3
