[PATCH v1 0/5] pinctrl: baytrail: Clean up (part 3)

[PATCH v1 0/5] pinctrl: baytrail: Clean up (part 3)

[Andy Shevchenko]

This is a part 3 of clean up pin control driver for Intel Baytrail.
After this applied the driver will use all available data structures
from pinctrl-intel.h header.

Note, that patch which exposes common pin control data structrure for drivers
will be used by Lynxpoint as well.

This has been tested on the tablet with SD card detection and buttons pressed.

Based on our pinctrl/intel for-next branch.

Andy Shevchenko (5):
  pinctrl: baytrail: Move IRQ valid mask initialization to a dedicated
    callback
  pinctrl: intel: Share struct intel_pinctrl for wider use
  pinctrl: baytrail: Keep pointer to struct device instead of its
    container
  pinctrl: baytrail: Use local variable to keep device pointer
  pinctrl: baytrail: Reuse struct intel_pinctrl in the driver

[PATCH v1 1/5] pinctrl: baytrail: Move IRQ valid mask initialization to a dedicated callback

[Andy Shevchenko]

There is a logical continuation of the commit 5fbe5b5883f8 ("gpio: Initialize
the irqchip valid_mask with a callback") to split IRQ initialization to
hardware and valid mask setup parts.

[PATCH v1 2/5] pinctrl: intel: Share struct intel_pinctrl for wider use

[Andy Shevchenko]

There are few drivers for Intel SoC GPIO which may utilize
the same data structure to describe this IP.

Share struct intel_pinctrl for wider user.

[PATCH v1 3/5] pinctrl: baytrail: Keep pointer to struct device instead of its container

[Andy Shevchenko]

There is no need to keep pointer to struct platform_device, which is container
of struct device, because the latter is what have been used everywhere outside
of ->probe() path. In any case we may derive pointer to the container when
needed.

 From a quick look this series looks good to me:

I've also added this to my personal tree for testing purposes, I will let
you know if I hit any problems.

Please collect up what you have and send this with a pull
request so I have the full picture in my tree soon-ish.

The reason is that I want a clean baseline to deal with this:

$ git grep gpiochip_set_chained_irqchip drivers/pinctrl/
drivers/pinctrl/intel/pinctrl-baytrail.c:
gpiochip_set_chained_irqchip(gc, &byt_irqchip,
drivers/pinctrl/intel/pinctrl-cherryview.c:
gpiochip_set_chained_irqchip(chip, &pctrl->irqchip, irq,
drivers/pinctrl/intel/pinctrl-intel.c:
gpiochip_set_chained_irqchip(&pctrl->chip, &pctrl->irqchip, irq,
NULL);

If you volunteer to get rid of these three gpiochip_set_chained_irqchip()
calls, even better :D

They are the three last users before I can delete
gpiochip_set_chained_irqchip() from the kernel.

Yours,
Linus Walleij

I see your point. I would like:
1/ wait for next rc (supposed to have the PR I sent and your applied recently)
2/ the rest to be hanging few days at least in Linux next.
