Merge tag 'pinctrl-v5.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"This is the bulk of the pin control changes for the v5.9 kernel
series:
Core changes:
- The GPIO patch "gpiolib: Introduce for_each_requested_gpio_in_range()
macro" was put in an immutable branch and merged into the pinctrl
tree as well. We see these changes also here.
- Improved debug output for pins used as GPIO.
New drivers:
- Ocelot Sparx5 SoC driver.
- Intel Emmitsburg SoC subdriver.
- Intel Tiger Lake-H SoC subdriver.
- Qualcomm PM660 SoC subdriver.
- Renesas SH-PFC R8A774E1 subdriver.
Driver improvements:
- Linear improvement and cleanups of the Intel drivers for
Cherryview, Lynxpoint, Baytrail etc. Improved locking among other
things.
- Renesas SH-PFC has added support for RPC pins, groups, and
functions to r8a77970 and r8a77980.
- The newere Freescale (now NXP) i.MX8 pin controllers have been
modularized. This is driven by the Google Android GKI initiative I
think.
- Open drain support for pins on the Qualcomm IPQ4019.
- The Ingenic driver can handle both edges IRQ detection.
- A big slew of documentation fixes all over the place.
- A few irqchip template conversions by yours truly.
