Hi Rafał,
I'm trying to use the new NVMEM cells with mt76 EEPROM bindings on an
mt7621 (SPI NOR flash) with mt79x5 (PCIe) based device, same way as you
did in 03b3284805 [1] and daaa0c1b25 [2] (ath79 target).
If I keep 'eeprom' within 'nvmem-layout', wifi doesn't work due to:
root@OpenWrt:/# cat /sys/kernel/debug/devices_deferred
0000:02:00.0pci: supplier
1e000b00.spi:flash@0:partitions:partition@50000:nvmem-layout not ready
Keeping 'eeprom' node outside 'nvmem-layout' gives expected results.
It seems there are only one (Netgear WNDR3700 v5) similar device under
ramips/mt7621, with 'eeprom' within 'nvmem-layout' defines and SPI NOR
(all other are NAND based, maybe related?) but I don't see any bug
reports (complains) about broken WiFi for it.
Any clue?
You can find related DTS in my staging tree [3].
Thanks!
