Mulin Chao	f9a4a3597b	soc: arm: npcx: move soc-specific register definitions to soc.h This CL is to minimize `CONFIG_SOC_SERIES_XXXX` definitions when we introduce a new chip series. Most of them are relevant to register layouts in different npcx soc series. It moves soc-specific register definitions from `reg_def.h` to its own soc.h file.

Mulin Chao	7411fbcb5b	pinctrl: npcx: add DEV_CTLx configuration support Add a new pinctrl type to control peripheral modules' specific IO characteristics such as tri-state, the power supply type selection (3.3V or 1.8V), and so on. In NPCX series, the corresponding registers/fields are irregular. This CL wraps these definitions to dt nodes and put them in pinctrl property if needed.

Mulin Chao	851e357aa4	pinctrl: npcx: add pinctrl support for psl pads This CL introduces how to configure PSL (Power Switch Logic) pads properties such as input detection mode/polarity, pin-muxing and so on via pinctrl mechanism. It includes: 1. Add two pinctrl properties and their enums for PSL input detection configuration. psl-in-mode: - "level" - "mode" psl-in-pole: - "low-falling" - "high-rising" 2. Add macro functions to get PSL input detection and pin-muxing configurations from 'pinmux', 'psl-offset' abd 'psl-polarity' properties. Here is an example to configure PSL_IN2 as the PSL detection input and its mode and polarity. /* A falling edge detection type for PSL_IN2 */ &psl_in2_gp00 { psl-in-mode = "edge"; psl-in-pol = "low-falling"; }; A device will be introduced later which uses this pinctrl node to configure PSL input detection settings and how to turn off VCC1 power rail by PSL_OUT.

Mulin Chao	0f18c4c4ab	pinctrl: npcx: config pwm open-drain without enabling STORE_REG Config pwm open-drain mode without enabling STORE_REG. This CL collects all active PWM's base address and related index in an array. Then, pinctrl driver configs its open-drain mode by finding the corresponding 'channel' index.

Mulin Chao	d53d574bf0	drivers: pinctrl: npcx: add initial pin-controller driver This CL is the initial version for npcx pinctrl driver and introduces pinctrl nodes for both IO-pads and peripheral devices for each npcx series. Users can set pin configuration via these nodes in the board layout DT file. It also wraps all configurations related to pin-muxing in pinctrl_soc.h. Regarding the other pin properties, we will implement them later. Signed-off-by: Mulin Chao <mlchao@nuvoton.com>	3 years ago
