Linus Torvalds ef991796be This is the bulk of pin control changes for the v4.16 kernel cycle:
Core changes:
 
 - After lengthy discussions and partly due to my ignorance, we have
   merged a patch making pinctrl_force_default() and pinctrl_force_sleep()
   reprogram the states into the hardware of any hogged pins, even
   if they are already in the desired state. This only apply to hogged
   pins since groups of pins owned by drivers need to be managed by
   each driver, lest they could not do things like runtime PM and
   put pins to sleeping state even if the system as a whole is not
   in sleep.
 
 New drivers:
 
 - New driver for the Microsemi Ocelot SoC. This is used in ethernet
   switches.
 
 - The X-Powers AXP209 GPIO driver was extended to also deal with pin
   control and moved over from the GPIO subsystem. This circuit is
   a mixed-mode integrated circuit which is part of AllWinner designs.
 
 - New subdriver for the Qualcomm MSM8998 SoC, core of a high end
   mobile devices (phones) chipset.
 
 - New subdriver for the ST Microelectronics STM32MP157 MPU and
   STM32F769 MCU from the STM32 family.
 
 - New subdriver for the MediaTek MT7622 SoC. This is used for routers,
   repeater, gateways and such network infrastructure.
 
 - New subdriver for the NXP (former Freescale) i.MX 6ULL. This SoC has
   multimedia features and target "smart devices", I guess in-car
   entertainment, in-flight entertainment, industrial control panels etc.
 
 General improvements:
 
 - Incremental improvements on the SH-PFC subdrivers for things like
   the CAN bus.
 
 - Enable the glitch filter on Baytrail GPIOs used for interrupts.
 
 - Proper handling of pins to GPIO ranges on the Semtec SX150X
 
 - An IRQ setup ordering fix on MCP23S08.
 
 - A good set of janitorial coding style fixes.

Linus Torvalds 9798f5178f The is the bulk of GPIO changes for the v4.16 kernel cycle.
Core changes:
 
 - Disallow open drain and open source flags to be set
   simultaneously. This doesn't make electrical sense, and would
   the hardware actually respond to this setting, the result
   would be short circuit.
 
 - ACPI GPIO has a new core infrastructure for handling quirks.
   The quirks are there to deal with broken ACPI tables centrally
   instead of pushing the work to individual drivers. In the world
   of BIOS writers, the ACPI tables are perfect. Until they find a
   mistake in it. When such a mistake is found, we can patch it
   with a quirk. It should never happen, the problem is that it
   happens. So we accomodate for it.
 
 - Several documentation updates.
 
 - Revert the patch setting up initial direction state from
   reading the device. This was causing bad things for drivers
   that can't read status on all its pins. It is only affecting
   debugfs information quality.
 
 - Label descriptors with the device name if no explicit label is
   passed in.
 
 - Pave the ground for transitioning SPI and regulators to use
   GPIO descriptors by implementing some quirks in the device tree
   GPIO parsing code.
 
 New drivers:
 
 - New driver for the Access PCIe IDIO 24 family.
 
 Other:
 
 - Major refactorings and improvements to the GPIO mockup driver
   used for test and verification.
 
 - Moved the AXP209 driver over to pin control since it gained a
   pin control back-end. These patches will appear (with the same
   hashes) in the pin control pull request as well.
 
 - Convert the onewire GPIO driver w1-gpio to use descriptors.
   This is merged here since the W1 maintainers send very few
   pull requests and he ACKed it.
 
 - Start to clean up driver headers using <linux/gpio.h> to just
   use <linux/gpio/driver.h> as appropriate.

When using mcp23s08 module with gpio-keys, often (50% of boots)
it fails to get irq numbers with message:
"gpio-keys keys: Unable to get irq number for GPIO 0, error -6".
Seems that irqs must be setup before devm_gpiochip_add_data().

Pin function can not be match correctly when SUNXI_PIN describe with
mutiple variant and same function.

such as:
on pinctrl-sun4i-a10.c

SUNXI_PIN(SUNXI_PINCTRL_PIN(B, 2),
		SUNXI_FUNCTION(0x0, "gpio_in"),
		SUNXI_FUNCTION(0x1, "gpio_out"),
		SUNXI_FUNCTION_VARIANT(0x2, "pwm",    /* PWM0 */
			PINCTRL_SUN4I_A10 |
			PINCTRL_SUN7I_A20),
		SUNXI_FUNCTION_VARIANT(0x3, "pwm",    /* PWM0 */
			PINCTRL_SUN8I_R40)),

it would always match to the first variant function
(PINCTRL_SUN4I_A10, PINCTRL_SUN7I_A20)

so we should add variant compare on it.

This driver creates a const structure that it stores in the data field
of an of_device_id array.

Adding const to the declaration of the location that receives the
const value from the data field ensures that the compiler will
continue to check that the value is not modified.  Furthermore, the
const-discarding cast on the extraction from the data field is no
longer needed.
