Inspired by D-Link DGS-1210-08P - first steps I started looking into supporting the DGS-1210-08P Rev. D1 and noticed that there is actually the GPL source available:

Digging into that it appears it´s based on a MIPS platform codenamed "music"
CPU := music
CPU_ARCH := mips
OS_TYPE := linux
export CPU CPU_ARCH OS_TYPE
ifeq ($(PROJECT_NAME),DGS1220_52)
BOARD_TYPE := b2b_test
MODEL_DGS1220_52 := yes
export MODEL_DGS1220_52
endif
ifeq ($(PROJECT_NAME),DGS1220_28)
BOARD_TYPE := UW8513A
MODEL_DGS1220_28 := yes
export MODEL_DGS1220_28
endif
ifeq ($(PROJECT_NAME),DGS1220_28P)
BOARD_TYPE := UW8513A
MODEL_DGS1220_28P := yes
export MODEL_DGS1220_28P
endif
ifeq ($(PROJECT_NAME),DGS1220_20)
BOARD_TYPE := UW8513A
MODEL_DGS1220_20 := yes
export MODEL_DGS1220_20
endif
ifeq ($(PROJECT_NAME),DGS1220_10P)
BOARD_TYPE := UW8513A
MODEL_DGS1220_10P := yes
export MODEL_DGS1220_10P
endif
The file
dgs-1210-4.10.023_08P_GPL/pkgs/sdk/asdk_branch_rc_patch_0.9.7.253/system/cpusub/music/linux/2.6.31/driver/timer/music_timer.c leads me to belive that it´s a Qualcom SOC that I couldn´t find anything about:
/*
* Qualcomm device driver API
* SOC timer
*/
Since I couldn´t find anything about a Qualcomm platform codenamed "music" I assume it either got renamed down the line or this is very obscure platform.
Does anyone have an idea of how to find out more about this platform?
