Merge tag 'pinctrl-v5.5-1' 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 pin control changes for v5.5.

  It is pretty much business as usual, the most interesting thing I
  think is the pin controller for a new Intel chip called Lightning
  Mountain, which is according to news reports some kind of embedded
  network processor and what is surprising about it is that Intel have
  decided to use device tree to describe the system rather than ACPI
  that they have traditionally favored.

  Core changes:

   - Avoid taking direct references to device tree-supplied device
     names: these may changed at runtime under certain circumstances to
     kstrdup them.

  GPIO related:

   - Work is ongoing to move to passing the irqchip along as a templated
     struct gpio_irq_chip when adding a standard gpiolib-based irqchip
     to a GPIO controller, a few patches in this cycle switches a few
     pin control drivers over to using this method.

  New hardware support:

   - Intel Lightning Mountain SoC pin controller and GPIO support, a
     first Intel platform to use device tree rather than ACPI to
     configure the system. News reports says that this SoC is a network
     processor.

   - Qualcomm MSM8976 and MSM8956

   - Qualcomm PMIC GPIO now also supports PM6150 and PM6150L

   - Qualcomm SPMI MPP and SPMI GPIO for PM8950 and PMI8950

   - Rockchip RK3308

   - Renesas R8A77961

   - Allwinner Meson-A1

  Driver improvements:

   - get_multiple and set_multiple support for the AT91-PIO4 driver.

   - Convert Qualcomm SSBI GPIO to use the hierarchical IRQ helpers in
     the GPIOlib irqchip"

+  #   - Then, the name itself can be any repetition of <string>- (to
+  #     accomodate with nodes like uart4-rts-cts-pins), where each
+  #     string can be either starting with 'p' but in a string longer
+  #     than 3, or something that doesn't start with 'p',
+  #   - Then, the bank name is optional and will be between pa and pg,
+  #     pl or pm. Some pins groups that have several options will have
+  #     the pin numbers then,
+  #   - Finally, the name will end with either -pin or pins.
