From 57bb2398bd5fb202cd9688a13c685992737d4c16 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Tue, 5 Oct 2021 16:55:54 +0300 Subject: dt-bindings: net: wireless: qca,ath9k: convert to the json-schema This replaces the existing .txt binding file. Furthermore, this also helps with validating DTS files. Introduced binding changes: 1. added inherited mac-address nvmem property 2. added inherited ieee80211-freq-limit property 3. added new calibration nvmem property 4. added second example (taken from the Netgear WNDR3700v2) Reason: Setting qca,no-eeprom; takes presedence over nvmem-cells. I think a different example is needed, because the driver can only reads from one calibration source per device. 5. (re-added) chip list (based on data from ath9k's pci.c) Added binding .yaml to MAINTAINERS.
