Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v5.4 kernel cycle:

Core changes:

- Fix errors in example code in the documentation.

New drivers:

- Add support for JZ4760, JZ4760B, X1000, X1000E and X1500 to the
Ingenic driver.

- Support Cirrus Logic Madera CS47L92 and CS47L15.

- Support Allwinner Sunxi V3S.

- Support Aspeed 2600 BMC.

- Support Qualcomm SC7180.

- Support Marvell MVEBU CS115.

Driver improvements:

- Clean up a few drivers to use the devm_platform_ioremap_resource()
helper.

- Pass the irqchip when registering the gpio_chip in some pin
controllers that are also GPIO controllers.

- Support suspend/resume in the Tegra driver.

- Support pull-up on the Broadcom BCM2711.

- The Intel driver can now request locked pads.

- Fix the UFS reset pin in the Qualcomm SDM845 driver"

gpio: Initialize the irqchip valid_mask with a callback

2019-09-11T00:09:37+00:00

After changing the valid_mask for the struct gpio_chip
to detect the need and presence of a valid mask with the
presence of a .init_valid_mask() callback to fill it in,
we augment the gpio_irq_chip to use the same logic.

Switch all driver using the gpio_irq_chio valid_mask
over to this new method.

This makes sure the valid_mask for the gpio_irq_chip gets
filled in when we add the gpio_chip, which makes it a
little easier to switch over drivers using the old
way of setting up gpio_irq_chip over to the new method
of passing the gpio_irq_chip along with the gpio_chip.
(See drivers/gpio/TODO for details.)

pinctrl: baytrail: Re-use data structures from pinctrl-intel.h (part 2)

2019-08-07T14:25:19+00:00

We have some data structures duplicated across the drivers.
Let's deduplicate them by using ones that being provided by
pinctrl-intel.h.

pinctrl: baytrail: Use devm_platform_ioremap_resource()

Use the new helper that wraps the calls to platform_get_resource()
and devm_ioremap_resource() together.

pinctrl: baytrail: Use GENMASK() consistently

2019-07-04T07:58:13+00:00

Use GENMASK() macro for all definitions where it's appropriate.
No functional change intended.

pinctrl: baytrail: Use defined macro instead of magic in byt_get_gpio_mux()

2019-07-04T07:48:49+00:00

By the fact byt_get_gpio_mux() returns a value of mux settings as
it is represented in hardware. Use defined macro instead of magic numbers
to clarify this.

pinctrl: baytrail: Fix potential NULL pointer dereference

2019-03-18T09:43:23+00:00

saved-context in byt_gpio_probe is allocated via devm_kcalloc and is
used without checking for NULL in later functions. This patch avoids
such a scenario.

pinctrl: baytrail: simplify getting .driver_data

2018-11-08T15:15:33+00:00

We should get 'driver_data' from 'struct device' directly. Going via
platform_device is an unneeded step back and forth.
