[PATCH 0/2] add ROG STRIX X870E-E GAMING WIFI

[Eugene Shalygin]

This adds the new board and increases the ACPI mutex lock timeout so
that the driver works with the ROG STRIX X870E-E GAMING WIFI board
without triggering frequent lock failures.

[PATCH 1/2] hwmon: (asus-ec-sensors) add ROG STRIX X870E-E GAMING WIFI

[Eugene Shalygin]

From: Ben Copeland <ben.copeland@linaro.org>

Add support for ROG STRIX X870E-E GAMING WIFI

This board uses the same sensor configuration as the
ProArt X870E-CREATOR WIFI motherboard.

[PATCH 2/2] hwmon: (asus-ec-sensors) increase timeout for locking ACPI mutex

[Eugene Shalygin]

From: Ben Copeland <ben.copeland@linaro.org>

Some motherboards require more time to acquire the ACPI mutex,
causing "Failed to acquire mutex" messages to appear in the kernel log.
Increase the timeout from 500ms to 800ms to accommodate these cases.
