Pull pin control updates from Linus Walleij:
 "We have GPIO awareness in the pin control core and an interesting
  AAEON driver.

  Core changes:

   - Allow pins to be identified/marked as GPIO mode with a special
     callback.

     The pin controller core is now "aware" if a pin is in GPIO mode if
     the callback is implemented in the driver, and can thus be marked
     as "strict", i.e. disallowing simultaneous use of a line as GPIO
     and another function such as I2C.

     This is enabled in the Qualcomm TLMM driver and also implemeted
     from day 1 in the new Broadcom STB driver

   - Rename the pin config option PIN_CONFIG_OUTPUT to PIN_CONFIG_LEVEL
     to better describe what the config is doing, as well as making it
     more intuitive what shall be returned when reading this property

  New drivers:

   - Qualcomm SDM660 LPASS LPI TLMM pin controller subdriver

   - Qualcomm Glymur family pin controller driver

   - Broadcom STB family pin controller driver

   - Tegra186 pin controller driver

   - AAEON UP pin controller support.

     This is some special pin controller that works as an external
     advanced line MUX and amplifier for signals from an Intel SoC. A
     cooperative effort with the GPIO maintainer was needed to reach a
     solution where we reuse code from the GPIO aggregator/forwarder
     driver

   - Renesas RZ/T2H and RZ/N2H pin controller support

   - Axis ARTPEC-8 subdriver for the Samsung pin controller driver

  Improvements:

   - Output enable (OEN) support in the Renesas RZG2L driver

   - Properly support bias pull up/down in the pinctrl-single driver

   - Move over all GPIO portions using generic MMIO GPIO to the new
     generic GPIO chip management which has a nice and separate API

   - Proper DT bindings for some older Broadcom SoCs

   - External GPIO (EGPIO) support in the Qualcomm SM8250

  Deleted code:

   - Dropped the now unused Samsung S3C24xx drivers"

+
+  This includes the pin controllers inside the BCM2712 SoC which

+
+  The -aon- (Always On) variant is the same IP block but differs
