Subject: [PATCH 00/13] nvmem: misc enhancements
Date: Sat, 19 Jun 2021 05:45:03 +0200	[thread overview]
Message-ID: <20210619034516.6737-1-a.fatoum@pengutronix.de> (raw)

Series implements some of the new NVMEM bindings:

- New providers:
  - nvmem-cells (for MTD partitions)
  - nvmem-rmem (memory regions passed by previous boot stages)

- New consumers:
  - Network devices: Unlike Linux, we do that for all drivers
    in generic code. This is done postenvironment, so network drivers,
    board code and other (OTP) drivers are not overridden.
  - nvmem-reboot-mode: To go along with syscon-reboot-mode
  - nvmem command: This one only prints registered devices for now

And changes sandbox to make use of it.

Ahmad Fatoum (13):
  nvmem: bsec: remove unused, left-over, struct member
  nvmem: treat devices without nvmem_bus::write as read only
  nvmem: add support for new read-only memory (rmem) binding
  nvmem: add support for nvmem-cells binding
  sandbox: use nvmem on top of stickypage for reset reason
  power: reset: port Linux generic NVMEM reboot mode driver
  sandbox: use nvmem-reboot-mode instead of syscon-reboot-mode
  sandbox: dts: fix unit-address for state partition
  nvmem: add command to list nvmem devices
  sandbox: hostfile: move initcall to earlier postcore level
  of: of_net: sync of_get_mac_address with Linux for NVMEM support
  net: consult device tree for ethernet address in NVMEM as fall-back
  sandbox: ship sample environment
