Subject: [PATCH v2 0/3] Read MAC address through NVMEM for sama7g5ek

This series proposes to add EEPROM support and reading MAC addresses through
NVMEM (via Devicetree) for sama7g5ek:
- Add in DT bindings document the EEPROM compatibles : "at24,mac02e4" and
"at24,mac02e6"
- Update to the driver to support "at24,mac02e4" and
"at24,mac02e6" and adjusting offset for those 24AA025E{48, 64}.
- Added the nodes in devicetree for eeproms where are stored eui48 MAC,
and update gmac nodes to read the MAC via devicetree through NVMEM.

------------------------------------------------------------------
v1 -> v2:
* dt-bindings: eeprom: at24: Add at24,mac02e4 and at24,mac02e6
  - change pattern into "^atmel,(24(c|cs|mac)[a-z0-9]+|spd)$" to keep simpler

* eeprom: at24: avoid adjusting offset for 24AA025E{48, 64}
  - no change

* ARM: dts: at91: at91-sama7g5ek: add EEPROMs
  - remove unnecessary #address-cells #size-cells
