Resources need to be shared between pinmux and plgpio. Introduce regmap phandle in order to retrieve the regmap from the phandle if the property is present. This allows to retrieve an external regmap (ie the one used by pinmux if the phandle references the pinmux node) from plgpio. Signed-off-by:

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.

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. Signed-off-by:

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. Signed-off-by:
