Changes in v7: - Drop "platform/x86: int3472: Enable I2c daisy chain" this workaround is no longer necessary (the regulator code now takes care of this) - Fix using PTR_ERR(data->clk) instead of PTR_ERR(rdev) to log an error code in "regulator: Introduce tps68470-regulator driver" Changes in v6: - Add support for the VCM (Voice Coil Motor) controlling the focus of the back/main sensor camera lens: - Patch 3 and patches 13-15 are new patches for this - While working on this I learned that the VIO regulator is an always on regulator and must be configured at the same voltage as VSIO, the tps68470-regulator driver and the constraints have been updated for this - Addressed clk-tps68470 driver review-remarks - Some minor tweaks based on review-remarks from Andy - Add Andy's Reviewed-by to all patches which were also in v5 I'm quite happy with how this works now, so from my pov this is ready for merging now. Patch 2 and 3 already have acks for merging through another tree. I believe the best way to merge this is that I create an IM branch with patches 1-4 + 7-11 (with Rafael's ack for 1) and then the clk / regulator / media maintainers merge my IM branch + their resp. patches This assumes that Rafael does not foresee any conflicts caused by the few small ACPI changes in patch 1. Rafael is this ok with you ? You did already Ack patch 1 but IIRC that was not specifically for merging it through another tree, may I have your ack for moving forward with this plan ?
