Subject: [PATCH v4 1/4] dt-bindings: gpio: convert rk3328-grf-gpio.txt to YAML

Current dts files with RK3328 GRF 'gpio' nodes are manually verified.
In order to automate this process rk3328-grf-gpio.txt has to be
converted to YAML.

Rename 'grf-gpio' nodename to 'gpio'.

-Rockchip RK3328 GRF (General Register Files) GPIO controller.
-
-In Rockchip RK3328, the output only GPIO_MUTE pin, originally for codec mute
-control, can also be used for general purpose. It is manipulated by the
-GRF_SOC_CON10 register in GRF. Aside from the GPIO_MUTE pin, the HDMI pins can
-also be set in the same way.
-
-Currently this GPIO controller only supports the mute pin. If needed in the
-future, the HDMI pins support can also be added.
-
-Required properties:
-- compatible: Should contain "rockchip,rk3328-grf-gpio".
-- gpio-controller: Marks the device node as a gpio controller.
-- #gpio-cells: Should be 2. The first cell is the pin number and
- the second cell is used to specify the gpio polarity:
- 0 = Active high,
- 1 = Active low.
-
-Example:
-
- grf: syscon@ff100000 {
- compatible = "rockchip,rk3328-grf", "syscon", "simple-mfd";
-
- grf_gpio: grf-gpio {
- compatible = "rockchip,rk3328-grf-gpio";
- gpio-controller;
- #gpio-cells = <2>;
- };
- };
-
-Note: The grf_gpio node should be declared as the child of the GRF (General
-Register File) node. The GPIO_MUTE pin is referred to as <&grf_gpio 0>.

-* Rockchip General Register Files (GRF)
-
-The general register file will be used to do static set by software, which
-is composed of many registers for system control.
-
-From RK3368 SoCs, the GRF is divided into two sections,
-- GRF, used for general non-secure system,
-- SGRF, used for general secure system,
-- PMUGRF, used for always on system
-
-On RK3328 SoCs, the GRF adds a section for USB2PHYGRF,
-
-ON RK3308 SoC, the GRF is divided into four sections:
-- GRF, used for general non-secure system,
-- SGRF, used for general secure system,
-- DETECTGRF, used for audio codec system,
-- COREGRF, used for pvtm,
-

Subject: [PATCH v4 4/4] arm64: dts: rename grf-gpio nodename in rk3328.dtsi

A test with the command below gives this error:

grf-gpio: {'compatible': ['rockchip,rk3328-grf-gpio'],

Due to the regex "(?<!,nr)-gpios?$" anything that ends on
'-gpio', '-gpios' gives a match.

Rename 'grf-gpio' nodename to generic 'gpio'
