Hi,
Please do not spend time to review v3.
V4 has been pushed to fix an issue in YAML bindings.
Regards,
Christophe Kerello.

The FMC2 functional block makes the interface with: synchronous and
asynchronous static devices (such as PSNOR, PSRAM or other memory-mapped
peripherals) and NAND flash memories.
Its main purposes are:
- to translate AXI transactions into the appropriate external device
protocol
- to meet the access time requirements of the external devices
All external devices share the addresses, data and control signals with the
controller. Each external device is accessed by means of a unique Chip
Select. The FMC2 performs only one access at a time to an external device.
Changes in v3:
- NAND:
- rename labels used on errors
- add in the commit log the reason to increase FMC2_TIMEOUT_MS (patch 3)
- add Miquel reviewed-by tag (patches 2/4/5/9)
- EBI:
- move in memory folder
- merge MFD and BUS drivers to avoid a MFD driver
- bindings:
- pattern name has been modified
- vendor properties have been modified
- s/_/-/
- add unit suffix (-ns) on timing properties
