Hi All,
Here is v7 of my patch-set adding support for camera sensor connected to a
TPS68470 PMIC on x86/ACPI devices.
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 ?
Regards,
Hans
