From: Steven Lee <steven_...@aspeedtech.com> Maps following unimplemented devices in SoC memory - dpmcu - iomem - iomem0 - iomem1 - ltpi
Iomem, Iomem0 and Iomem1 include unimplemented controllers in the memory ranges 0x0 - 0x1000000, 0x120000000 - 0x121000000 and 0x14000000 - 0x141000000. For instance: - USB hub at 0x12010000 - eSPI at 0x14C5000 - PWM at 0x140C0000 DPMCU stands for Display Port MCU controller. LTPI is used to connect to AST1700. AST1700 is an I/O expander that supports the DC-SCM 2.1 LTPI protocol. It provides AST2700 with additional GPIO, UART, I3C, and other interfaces.
