Hi Greg,
This series contain the final bits needed for the USB3 bus to work without
staging drivers on Hikey 970. It is based on next-20210714, as it depends
on a patch on this branch:
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-next
v14:
- use platform_get_irq() instead of of_get_gpio().
v13:
- Addressed an issue pointed by Rob Herring at the DT file (patch 6).
v12:
- Added Mark Brown's ack to patch 5;
- Addressed a couple issues at the DT binding, as pointed by Rob Herring
(patch 1).
Mauro Carvalho Chehab (9):
staging: hi6421-spmi-pmic: rename spmi_device struct

Instead of using the standard name ("gpios"), use "interrupts".

The regex at the patternProperties is wrong, although this was
not reported as the DT schema was not enforcing properties.
Fix it.

2.31.1
Add a device tree for the HiSilicon 6421v600 SPMI PMIC, used
on HiKey970 board.
As we now have support for it, change the fixed regulators
used by the SD I/O to use the proper LDO supplies.

2.31.1
There are lots of fields at struct hi6421_spmi_pmic that aren't
used. In a matter of fact, only regmap is needed.
So, drop the struct as a hole, and set just the regmap as
the drvdata.
While here, add a missing dot at the Huawei's copyrights.

Ideally Rob would give this the once over.
If he's reviewed this before and there haven't been any significant
changes, perhaps you can bring his Ack over with the file.

Looks good to me now, thanks.

This patch fails to apply to my 5.14-rc2 tree, it gets a failure in the
regulator portion of the patch.

Hi Greg,
This one depends on a regression-fix patch merged via this branch:
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-next
The patch is this one[1]:
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git/commit/drivers/regulator/hi6421v600-regulator.c?id=5db5dd5be70eaf808d9fd90174b957fc5c2912cb
Mark,
Is this branch stable or do you rebase it?
If the branch is stable, then perhaps Greg could merge from it before
applying the remaining patches from this series.
-
[1] There's no need of backporting the fix to stable, as the driver
won't work with upstream Kernels without patches 8 and 9 from
this series containing the Open Firmware data needed to probe it.
Thanks,
Mauro
