gd,gd32-flash-controller
Vendor: GigaDevice Semiconductor
Note
An implementation of a driver matching this compatible is available in drivers/flash/flash_gd32.c.
Description
There are three types GD32 FMC.
GD32 FMC v1: its flash memory has 1 bank, page size is equal in the bank,
flash size is smaller than 512KB.
GD32 FMC v2: its flash memory has 2 banks. Page size equal within the same bank but
different between banks. Flash size can be up to 3072KB. FMC v2 has two
registers to control bank0 and bank1 separately.
GD32 FMC v3: its flash memory has 2 banks, use sector size as the minimum operating
unit, the sector size is not equal.

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
