Message

This patch series introduces a new hardware monitoring (hwmon) driver for
the MAX42500 hardware. The driver is a SoC power-system monitor with up to
seven voltage monitor inputs. Each input has programmable OV/UV thresholds
over the full temperature range and support DVS through the I2C interface.

The MAX42500 contains a programmable flexible power sequence recorder
(FPSR) and a programmable challenge/response watchdog with a configurable
RESET output. These are also accessible through the I2C interface.

The patches are organized as follows:
1. Patch 1/2: Add documentation for devicetree bindings of MAX42500 driver.
2. Patch 2/2: Add the core implementation of the MAX42500 hwmon driver.

The driver has been tested on the raspberry pi-4 platform.
