Subject: [PATCH] dt-bindings: mt76: support pointing to EEPROM using NVMEM cell
From: Rafał Miłecki <rafal@...ecki.pl>
All kind of calibration data should be described as NVMEM cells of NVMEM
devices. That is more generic solution than "mediatek,mtd-eeprom" which
is MTD specific.
Add support for EEPROM NVMEM cells and deprecate existing MTD-based
property.

Ansuel is working on mt76 driver support for NVMEM based EEPROM access:
https://github.com/openwrt/mt76/pull/765
I took the liberty to propose this binding patch.
One important difference: my binding uses "eeprom" while Ansuel went
with "precal". I found a lot of "eeprom" references and only one
"precal". If you think however "precal" fits better please comment.
