intel-pinctrl for 5.9-1

Hi Linus,

Intel pin controller driver for v5.9. No conflicts found, no build / other issues. Nevertheless it contains one fix that has been already applied during v5.8 cycle.

Thanks,

With Best Regards,
Andy Shevchenko

 -  Fix pin being driven low for a while on gpiod_get(..., GPIOD_OUT_HIGH)
 -  Drop no-op ACPI_PTR() call

cherryview:

 -  Re-use data structures from pinctrl-intel.h (part 3)
 -  Convert chv_writel() to use chv_padreg()
 -  Introduce helpers to IO with common registers
 -  Introduce chv_readl() helper

gpio:
- xra1403: Make use of for_each_requested_gpio()
- mvebu: Make use of for_each_requested_gpio()

gpiolib:
- Introduce for_each_requested_gpio_in_range() macro

intel:

 -  Add Intel Emmitsburg pin controller support
 -  Make use of for_each_requested_gpio_in_range()
 -  Protect IO in few call backs by lock
 -  Split intel_config_get() to three functions
 -  Drop the only label in the code for consistency
 -  Get rid of redundant 'else' in intel_config_set_debounce()
 -  Make use of IRQ_RETVAL()
 -  Reduce scope of the lock
 -  Disable input and output buffer when switching to GPIO
 -  Allow drivers to define ACPI address space ID
 -  Allow drivers to define total amount of IRQs per community

lynxpoint:

 -  Drop no-op ACPI_PTR() call
 -  Introduce helpers to enable or disable input
 -  Make use of for_each_requested_gpio()

merrifield:
- Add I²S bus 2 pins to groups and functions
- Update pin names in accordance with official list

tigerlake:
- Add support for Tiger Lake-H

Hi Andy!

(...)

Are these dependent on this:

Because if they only need for_each_requested_gpio() I could just merge it to the gpio tree, since I have merged the immutable branch for that into both trees. Then I'd prefer to have one pinctrl and one gpio pull request.

However if they explicitly need for_each_requested_gpio_in_range() I say I can compromise and merge it all into pinctrl.

Yours,
Linus Walleij

It uses usual practice, i.e. merge of immutable branches. The pin control stuff is dependent on this immutable branch (first patch).

I would like to avoid rebasing and doing it differently.

P.S. It should be no-op from Git perspective.

Andy Shevchenko

Ahh I see, yeah this is the situation when the shortlog becomes quite confusing.

No problem, pulled it in now!

Yours,
Linus Walleij
