cover Add support for Kirin 970 PMIC and USB3

As the PMIC driver was finally promoved from staging, add the DT properties for both PMIC and USB3 for HiKey 970.

PATCH 1/2 dts: hisilicon: add support for the PMIC found on Hikey 970

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.

No.

hisilicon,hi6421-pmic is used by this driver

	drivers/mfd/hi6421-pmic-core.c

which provides support for the Hi6421 variants that don't use a MIPI SPMI bus.

The "hisilicon,hi6421-spmi" compatible is for the new driver:

	drivers/mfd/hi6421-spmi-pmic.c

And it is defined at:
Documentation/devicetree/bindings/mfd/hisilicon,hi6421-spmi-pmic.yaml

Both DT bindings and the driver were promoted from staging on this patch:

	https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git/commit/?h=staging-next&id=9bd9e0de1cf5b89c4854be505ac0a418ddcc01bf

Whatever works best for you and Greg.

It should be noticed that the driver should be out of staging for v5.15-rc1 (as the patch moving it out of staging was already merged at Greg's tree). This patch is needed by the PCI driver patchset I'm currently working, so the best would be if this patch could also be merged for v5.15-rc1 (either via HiSilicon tree or via staging tree).

I suspect that having your ack and merging this via staging would work best, as this would ensure that both changes will be merged upstream at the same time.

But, as I said, it is up to you both ;-)

Thanks,
Mauro

Should this be "hisilicon,hi6421-pmic" which is already in the binding document "mfd/hi6421.txt"? Others are OK to me.

No.

hisilicon,hi6421-pmic is used by this driver

	drivers/mfd/hi6421-pmic-core.c

which provides support for the Hi6421 variants that don't use a MIPI SPMI bus.

The "hisilicon,hi6421-spmi" compatible is for the new driver:

	drivers/mfd/hi6421-spmi-pmic.c

And it is defined at:
Documentation/devicetree/bindings/mfd/hisilicon,hi6421-spmi-pmic.yaml

Quoted 7 lines
Quoted 3 lines

Both DT bindings and the driver were promoted from staging on this patch:

	https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git/commit/?h=staging-next&id=9bd9e0de1cf5b89c4854be505ac0a418ddcc01bf  

Got it. Thanks for your kind explanation!
So I am fine with this patch.
Do you need my ack now or later I can merge it once it is out of staging.

Whatever works best for you and Greg.

It should be noticed that the driver should be out of staging for v5.15-rc1 (as the patch moving it out of staging was already merged at Greg's tree). This patch is needed by the PCI driver patchset I'm currently working, so the best would be if this patch could also be merged for v5.15-rc1 (either via HiSilicon tree or via staging tree).

Quoted 5 lines

I suspect that having your ack and merging this via staging would work best, as this would ensure that both changes will be merged upstream at the same time.

But, as I said, it is up to you both ;-)

Got it.
To avoid dependency, I think it is better to be merged by Greg's tree. So for this patch,

Best Regards,
Wei

Add the USB3 bindings for Kirin 970 phy and Hikey 970 board.

Fine to me and I can merge this patch once the binding for the "kirin970_hikey_usbhub" and "hi3670-dwc3" are ready.

The compatible:

	"hisilicon,hi3670-dwc3"

was already merged upstream on this patch:

commit b68d9251561f33661e53dd618f1cafe7ec9ec3c2

AuthorDate: Tue Sep 8 11:58:23 2020 +0200

CommitDate: Thu Sep 24 11:56:01 2020 +0300

usb: dwc3: simple: add support for Hikey 970

This binding driver is needed for Hikey 970 to work, as otherwise a Serror is produced:

It follows the DWC3 schema, e. g.:

Documentation/devicetree/bindings/usb/snps,dwc3.yaml

While double checking for "kirin970_hikey_usbhub", it sounds that the dt-binding patch was not merged yet, and require further discussions.

I'll re-start the upstream thread where this was discussed in the past. I'll re-submit this patch once we finish such discussions.

Thanks,
Mauro
