Merge tag 'intel-pinctrl-v5.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/pinctrl/intel into devel
intel-pinctrl for v5.9-1
* New driver for Emmitsburg
* New driver for Tiger Lake-H
* Part 3 of Cherryview driver clean up
* Fix a glitch on Baytrail platforms
The following is an automated git shortlog grouped by driver:
ARM/orion/gpio:
- Make use of for_each_requested_gpio()
at91:
- Make use of for_each_requested_gpio()
baytrail:
- Use fallthrough pseudo-keyword
- 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
