SOC_THERM is the primary hardware component of Tegra on-die thermal
management strategies. SOC_THERM includes the function of
externally-signaled event detection (SOC_THERM_edp) which centralizes
a few mechanisms for detecting and responding to externally signaled
electrical events, such as overcurrent events, undervoltage events, and
so on. These are known as "OC alarms" because they often indicate an
overcurrent event.
The Jetson Module's on-board power monitor INA3221 is configured to
trigger CPU/GPU hardware clock throttling via Tegra234 SOCTHERM_OC when
the Module input current exceeds the preprogrammed overcurrent threshold
to keep Module power consumption within the TDP power budget.
CPU/GPU performance may drop when hardware clock throttling occurs.
To allow the user to infer whether the performance degradation is
related to the overcurrent event, the Tegra234 OC event driver is
implemented which sends a Message ReQuest (MRQ) to the BPMP firmware to
provide information regarding the overcurrent enable state and the event
count to userspace via the hwmon sysfs interface.

Upstream Linux commit 03c835f498b5 ("i2c: Switch .probe() to not take an
id parameter") removes the 'id' argument from the I2C probe callback.
Update the drivers which define an I2C probe callback function to fix
building them for Linux v6.3.

Upstream Linux commit f59ac19b7f44 ("thermal/of: Remove old OF code")
removes the structure "thermal_zone_of_device_ops" and function
devm_thermal_zone_of_sensor_register() which breaks building the pex9749
driver with Linux v6.1. Update the pex9749 driver as necessary to fix
building with Linux v6.1.
