Subject: [PATCH 0/9] AT24 EEPROM MTD Support
Date: Mon, 01 Jul 2024 15:53:39 +0200 [thread overview]
Message-ID: <20240701-b4-v6-10-topic-usbc-tcpci-v1-0-3fd5f4a193cc@pengutronix.de> (raw)
This series adds the intial support to handle EEPROMs via the MTD layer
as well. This allow the user-space to have separate paritions since
EEPROMs can become quite large nowadays.
With this patchset applied EEPROMs can be accessed via:
- legacy 'eeprom' device
- nvmem device
- mtd device(s)
The patchset targets only the AT24 (I2C) EEPROMs since I have no access
to AT25 (SPI) EEPROMs nor to one of the other misc/eeprom/* devices.
Note: I'm not familiar with Kconfig symbol migration so I don't know if
the last patch is required at the moment. Please be notified that the
list of recipients is quite large due to the defconfig changes.
Regards,
Marco
