Pull pin control updates from Linus Walleij:
 "Nothing stands out, apart from maybe the interesting Eswin EIC7700, a
  RISC-V SoC I've never seen before.

  Core changes:

   - Open code PINCTRL_FUNCTION_DESC() instead of defining a complex
     macro only used in one place

   - Add pinmux_generic_add_pinfunction() helper and use this in a few
     drivers

  New drivers:

   - Amlogic S7, S7D and S6 pin control support

   - Eswin EIC7700 pin control support

   - Qualcomm PMIV0104, PM7550 and Milos pin control support

     Because of unhelpful numbering schemes, the Qualcomm driver now
     needs to start to rely on SoC codenames

   - STM32 HDP pin control support

   - Mediatek MT8189 pin control support

  Improvements:

   - Switch remaining pin control drivers over to the new GPIO set
     callback that provides a return value

   - Support RSVD (reserved) pins in the STM32 driver

   - Move many fixed assignments over to pinctrl_desc definitions

   - Handle multiple TLMM regions in the Qualcomm driver"

  subnodes. Each of these subnodes represents some desired configuration for one or
  more pins. This configuration can include the mux function to select on those pin(s),
  and various pin configuration parameters, such as input-enable, pull-up, etc.

- clocks		: Clock specifier (see clock bindings for details)

The lpc1850-scu driver uses the generic pin multiplexing and generic pin
configuration documented in pinctrl-bindings.txt.

The following generic nodes are supported:
 - function
 - pins
 - bias-disable
 - bias-pull-up
 - bias-pull-down
 - drive-strength
 - input-enable
 - input-disable
 - input-schmitt-enable
 - input-schmitt-disable
 - slew-rate

NXP specific properties:
 - nxp,gpio-pin-interrupt : Assign pin to gpio pin interrupt controller
			    irq number 0 to 7. See example below.

Not all pins support all properties so either refer to the NXP 1850/4350
user manual or the pin table in the pinctrl-lpc18xx driver for supported
pin properties.

Example:
pinctrl: pinctrl@40086000 {
	compatible = "nxp,lpc1850-scu";
	reg = <0x40086000 0x1000>;
	clocks = <&ccu1 CLK_CPU_SCU>;

	i2c0_pins: i2c0-pins {
		i2c0_pins_cfg {
			pins = "i2c0_scl", "i2c0_sda";
			function = "i2c0";
			input-enable;
		};
	};

	uart0_pins: uart0-pins {
		uart0_rx_cfg {
			pins = "pf_11";
			function = "uart0";
			bias-disable;
			input-enable;
		};

		uart0_tx_cfg {
			pins = "pf_10";
			function = "uart0";
			bias-disable;
		};
	};

	gpio_joystick_pins: gpio-joystick-pins {
		gpio_joystick_1_cfg {
			pins =  "p9_0";
			function = "gpio";
			nxp,gpio-pin-interrupt = <0>;
			input-enable;
			bias-disable;
		};
	};
};
