* Nuvoton FLASH Interface Unit (FIU) SPI Controller
|
||||
|
||||
NPCM FIU supports single, dual and quad communication interface.
|
||||
|
||||
The NPCM7XX supports three FIU modules,
|
||||
FIU0 and FIUx supports two chip selects,
|
||||
FIU3 support four chip select.
|
||||
|
||||
Required properties:
|
||||
- compatible : "nuvoton,npcm750-fiu" for the NPCM7XX BMC
|
||||
- #address-cells : should be 1.
|
||||
- #size-cells : should be 0.
|
||||
- reg : the first contains the register location and length,
|
||||
the second contains the memory mapping address and length
|
||||
- reg-names: Should contain the reg names "control" and "memory"
|
||||
- clocks : phandle of FIU reference clock.
|
||||
|
||||
Required properties in case the pins can be muxed:
|
||||
- pinctrl-names : a pinctrl state named "default" must be defined.
|
||||
- pinctrl-0 : phandle referencing pin configuration of the device.
|
||||
|
||||
Optional property:
|
||||
- nuvoton,spix-mode: enable spix-mode for an expansion bus to an ASIC or CPLD.
|
||||
|
||||
Aliases:
|
||||
- All the FIU controller nodes should be represented in the aliases node using
|
||||
the following format 'fiu{n}' where n is a unique number for the alias.
|
||||
In the NPCM7XX BMC:
|
||||
fiu0 represent fiu 0 controller
|
||||
fiu1 represent fiu 3 controller
|
||||
fiu2 represent fiu x controller
|
||||

Then we need one hardware spinlock to synchronize between the multiple subsystems.

The new version ADI controller supplies multiple master channels for different
