8a8d6bbe1d pinctrl: Get rid of duplicate of_node assignment in the drivers 
GPIO library does copy the of_node from the parent device of
the GPIO chip, there is no need to repeat this in the individual
drivers. Remove these assignment all at once.

For the details one may look into the of_gpio_dev_init() implementation.

12422af819 pinctrl: Add Intel Thunder Bay pinctrl driver 
About Intel Thunder Bay:
-----------------------
Intel Thunder Bay is a computer vision AI accelerator SoC based on ARM CPU.

Pinctrl IP:
----------
The SoC has a customised pinmux controller IP which controls pin
multiplexing and configuration.

Thunder Bay pinctrl IP is not based on and have nothing in common with the
existing pinctrl drivers. The registers used are incompatible with the
existing drivers, so it requires a new driver.

Add pinctrl driver to enable pin control support in the Intel Thunder Bay
SoC.

bceb6732f3 pinctrl/rockchip: fix gpio device creation 
GPIO nodes are not themselves busses, so passing rockchip_bank_match
here is wrong.  Passing NULL instead uses the standard bus match table
which is more appropriate.

devm_of_platform_populate() shows that this is the normal way to call
of_platform_populate() from a device driver, so in order to match that
more closely also add the pinctrl device as the parent for the newly
created GPIO controllers.

Specifically, using the wrong match here can break dynamic GPIO hogs as
marking the GPIO bank as a bus means that of_platform_notify() will set
OF_POPULATED on new child nodes and if this happens before
of_gpio_notify() is called then the new hog will be skipped as
OF_POPULATED is already set.

1dd19cae15 dt-bindings: pinctrl: uniphier: Add child node definitions to describe pin mux and configuration 
In arch/arm/boot/dts/uniphier-pinctrl.dtsi, there are child nodes of
pinctrl that defines pinmux and pincfg, however, there are no rules about
that in dt-bindings.

'make dtbs_check' results an error with the following message:

   pinctrl: 'ain1', 'ain2', 'ainiec1', 'aout', 'aout1', 'aout2', ...
   ... 'usb2', 'usb3' do not match any of the regexes: 'pinctrl-[0-9]+'

To avoid the issue, add the rules of pinmux and pincfg in each child node
and grandchild node.

sc7280 supports the egpio feature, GPIOs ranging from 144 to 174

bebc49c1e5 pinctrl: qcom: Add egpio feature support 
egpio is a scheme which allows special power Island Domain IOs
(LPASS,SSC) to be reused as regular chip GPIOs by muxing regular
TLMM functions with Island Domain functions.
With this scheme, an IO can be controlled both by the cpu running
linux and the Island processor. This provides great flexibility to
re-purpose the Island IOs for regular TLMM usecases.

2 new bits are added to ctl_reg, egpio_present is a read only bit
which shows if egpio feature is available or not on a given gpio.
egpio_enable is the read/write bit and only effective if egpio_present
is 1. Once its set, the Island IO is controlled from Chip TLMM.
egpio_enable when set to 0 means the GPIO is used as Island Domain IO.

To support this we add a new function 'egpio' which can be used to
set the egpio_enable to 0, for any other TLMM controlled functions
we set the egpio_enable to 1.
