Subject: [PATCH v3 0/2] dt: bindings: net: ath11k: add dt entry for XO calibration support

Add dt binding to get XO calibration data support for Wi-Fi RF clock.

Retrieve the XO trim offset via system firmware (e.g., device tree),
especially in the case where the device doesn't have a useful EEPROM
on which to store the calibrated XO offset.
Calibrated XO offset is sent to firmware, which compensate the RF clock
drift by programing the XO trim register.

Changes from v2:
 - Added proper commit text

Changes from v1:
 - Sending the series to right list
