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 :
"microchip,24aa025e48" and "microchip,24aa025e64"
- Update to the driver to support "microchip,24aa025e48" and
"microchip,24aa025e64" and adjusting offset for those 24AA025E{48, 64}.
- Added the nodes in devicetree for eeproms where are stored EUI-48 MAC,
and update gmac nodes to read the MAC via devicetree through NVMEM.
------------------------------------------------------------------
v2 -> v3:
* dt-bindings: eeprom: at24: Add Microchip 24AA025E48/24AA025E64
- commit subject changed to reference Microchip 24AA025E48/24AA025E64
- drop the pattern: mac02e4$ and mac02e6$ and a-z from regex
- add these two devices down at the bottom
- added Reviewed-by
* eeprom: at24: avoid adjusting offset for 24AA025E{48, 64}
- add specific compatible names according with
https://ww1.microchip.com/downloads/en/DeviceDoc/24AA02E48-24AA025E48-24AA02E64-24AA025E64-Data-Sheet-20002124H.pdf
- add extended macros to initialize the structure with explicit value for adjoff
- drop co-developed-by to maintain the commit history
(chronological order of modifications)
* ARM: dts: at91: at91-sama7g5ek: add EEPROMs
- change from atmel,24mac02e4 to microchip,24aa025e48 to align with the datasheet
- drop co-developed-by to maintain the chronological order of the changes
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
