Subject: Re: [PATCH 2/5] aspeed: ast27x0: Map unimplemented devices in SoC
memory
Hello,

Maps following unimplemented devices in SoC memory
- dpmcu
- iomem0
- iomem1
- ltpi
- io
Could you please add a sentence about what these devices are ?
Thanks,
C.
DPMCU stands for Display Port MCU controller.
Regarding LTPI, when the AST1700 is connected to the AST2700, AST1070 LTPI
controller's registers are mapped to 0x30000000.
Is the LTPI IP a device for communication between SoCs ?
Io, Iomem0 and Iomem1 include unimplemented controllers in the memory ranges
0x120000000 - 0x121000000 and 0x14000000 - 0x141000000.
For instance:
- USB hub at 0x12010000
- eSPI at 0x14C5000
- PWM at 0x140C0000
I will include the description in the commit message.
yes please.
Thanks,
C.
