Subject: [PATCH v4 00/15] Add functionality to ipu3-cio2 driver allowing software_node connections to sensors on platforms designed for Windows
Hello all
v3:
https://lore.kernel.org/linux-media/20201224010907.263125-1-djrscally@gmail.com/T/#m37b831bb2b406917d6db5da9acf9ed35df65d72d
v2:
https://lore.kernel.org/linux-media/20201217234337.1983732-1-djrscally@gmail.com/T/#md93fd090009b42a6a98aed892aff0d38cf07e0cd
v1:
https://lore.kernel.org/linux-media/20201130133129.1024662-1-djrscally@gmail.com/T/#m91934e12e3d033da2e768e952ea3b4a125ee3e67
The RFC version before that:
https://lore.kernel.org/linux-media/20201019225903.14276-1-djrscally@gmail.com/
This series is to start adding support for webcams on laptops with ACPI tables
designed for use with CIO2 on Windows. This problem has two main parts; the
first part, which is handled in this series, is extending the ipu3-cio2
driver to allow for patching the firmware via software_nodes if endpoints
aren't defined by ACPI. The second is adding a new driver to handle power,
clocks and GPIO pins defined in DSDT tables in an awkward way. I decided to
split that second part out from this series, and instead give it its own
series (a v2 of which should land "soon"). The reasons for that are:
1. It's a logically separate change anyway
2. The recipients list was getting really long and
3. That probably meant that handling merge for all of this in one go was
going to be impractically awkward.
I'm hopeful that most or all of this series could get picked up for 5.12.
We touch a few different areas (listed below), but I think the easiest
approach would be to merge everything through media tree. Rafael, Greg,
Mauro and Sergey; are you ok with that plan, or would you prefer a
different approach? Mauro; if that plan is ok (and of course assuming that
the rest of the patches are acked by their respective maintainers) could
we get a dedicated feature branch just in case the following series ends
up being ready in time too?
