PS.: this series is identical to the one I posted earlier today. The only difference
  is that it was generated with --no-renames, as per Lee Jones request,
  in order to make easier to review the code.

Hi Greg,

Those are the remaining patches that are needed for the USB to work
with Hikey970. This is based on the top of next-20210323.

The main change from the previous patch series is that a new patch
was added:
  - staging: hisilicon,hisi-spmi-controller.yaml cleanup schema

It does some changes at the DT binding file, as requested by Rob.

My understanding from the discussions we had, back on Feb, is that
those patches will be merged via the staging tree.

Thanks!
Mauro

The phy USB3 driver for Hisilicon 970 (hi3670) is ready
for mainstream. Mode it from staging into the main driver's
phy/ directory.

Remove some properties already defined at SPMI bus, and
place the type for the spmi-channel.

+description: |
+  HiSilicon 6421v600 should be connected inside a MIPI System Power Management
+  (SPMI) bus. It provides interrupts and power supply.
+
+  The GPIO and interrupt settings are represented as part of the top-level PMIC
+  node.
+
+  The SPMI controller part is provided by
+  drivers/staging/hikey9xx/hisilicon,hisi-spmi-controller.yaml.

-
-	  This driver includes core APIs _only_. You have to select

-	  We communicate with the Hi6421v600 via a SPMI bus.

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.

return regmap_update_bits() ?
 (i see few more in driver like this, pls change others as well)

What's 8?

This is also misleading, since there are only 14 IRQs.

What's this please?

This is not great nomenclature.

What do the 'bits' represent?

> +#define HISI_IRQ_KEY_VALUE		(BIT(POWERKEY_DOWN) | BIT(POWERKEY_UP))

This should probably be with the other HISI_IRQ_KEY* variable.

Along with a short comment on what an IRQ_KEY is.

Pair this with HISI_BITS and explain what there are 8 of.

Does IRQ handling not have a base?

If so, would it be worth passing the base to Regmap, instead of
mapping a large, mostly unused area?

What's 3?

The naming of this macro makes it looks generic.

Please add some namespacing to clarify.

More undocumented masks and bits.

This is odd nomenclature.

Do these have another name in the datasheet?  Bank maybe?

Okay, so 'KEY' is actually 'POWERKEY'.

This should be made clear sooner.

Bracketing?

IRQ_MASK_REGISTER() ?

BIT()?

Is this the only 'pmic' on the platform?

This is IRQ GPIOs.

Right now, the drive calls:

	ddata->gpio = of_get_gpio(np, 0);

which is an alias for of_get_named_gpio_flags() that hardcode the
name "gpios":

	static inline int of_get_gpio_flags(struct device_node *np, int index,
			      enum of_gpio_flags *flags)
	{
		return of_get_named_gpio_flags(np, "gpios", index, flags);
	}

It shouldn't be hard to replace it by:

	ddata->gpio = of_get_named_gpio_flags(np, "irq-gpio", 0, NULL);

but it sounds that most drivers just use of_get_gpio(). The only one
doing it differently seems to be this one:

	$ git grep -A1 of_get_named_gpio_flags|grep irq
	drivers/mfd/stmpe.c:	pdata->irq_gpio = of_get_named_gpio_flags(np, "irq-gpio", 0,
	drivers/mfd/stmpe.c-				&pdata->irq_trigger);

While the usage of "gpios" (without a prefix) seems to be more usual:

	$ git grep -l of_get_gpio|grep -vE '(of_gpio.h|gpiolib.c)'
	arch/mips/lantiq/xway/vmmc.c
	arch/powerpc/platforms/44x/warp.c
	arch/powerpc/platforms/85xx/sgy_cts1000.c
	drivers/input/touchscreen/auo-pixcir-ts.c
	drivers/media/i2c/s5k6a3.c
	drivers/mfd/hi6421-spmi-pmic.c
	drivers/pcmcia/at91_cf.c
	drivers/regulator/gpio-regulator.c
	drivers/soc/fsl/qe/gpio.c
	drivers/spi/spi-mpc52xx.c
	drivers/usb/host/fhci-hcd.c
	sound/soc/codecs/ssm2518.c

Yet, as this is a new driver, if you prefer, I can use the named
variant and use either "irq-gpio" or "irq-gpios". Just let me know
the preference.

Thanks,
Mauro
