drivers: adc: add adc support in npcx7 series NPCX7 includes a 10-bit resolution Analog-to-Digital Converter (ADC). Up to 10 voltage inputs can be measured and a internal voltage reference (VREF), 2.816V (typical) is used for measurement. It can be triggered automatically in Autoscan mode. Each input channel is assigned a separate result register, which is updated at the end of the conversion. The CL also includes: — Add npcx adc device tree declarations. — Zephyr adc api implementation. — Add adc definitions of npcx7 in tests/drivers/adc/adc_api/src/test_adc.c for supporting test suites.

drivers: adc: add pinctrl driver support Replace soc-specific pin functions with Zephyr pinctrl api functions for pin-mux configuration in npcx adc driver. Please notice users need to configure the corresponding pinctrl nodes in 'pinctrl-0' property in the adc0 DT node. For example, if ADC0 and ADC2 channels are selected for the application, please add the follwoings in your board DT layout file. &adc0 { status = "okay"; /* Use adc0 channel 0 and 2 for 'adc_api' driver tests */ pinctrl-0 = <&adc0_chan0_gp45 &adc0_chan2_gp43>; pinctrl-names = "default"; }; Signed-off-by: Mulin Chao <mlchao@nuvoton.com>

driver: adc: npcx: add multi-device support in npcx adc driver Add multi-device support in npcx adc driver since there is more than one adc module in npcx4 series. And each adc's reference voltage might be different, this CL introduces the `vref-mv` prop. to select its own reference voltage.
