[PATCH v7 4/6] MIPS: Ingenic: Initial YSH & ATIL CU Neo board support.

周琰杰 (Zhou Yanjie)
2019-12-09T13:01:33Z

Add a device tree for the Ingenic X1000 based YSH & ATIL CU Neo board.
Note that this is unselectable via Kconfig until the X1000 SoC is made
selectable in a later commit.

Notes:
v1->v2:
Rebase on top of mips-next, use TCU for system timer and clocksource.

v2->v3:
No change.

v3->v4:
1.Adjust "model" in "cu1000.dts" to match the description in "devices.yaml".
2.Adjust "bool" in "Kconfig" to avoid duplicate names with subsequent boards.

v4->v5:
1.Rename "cu1000" to "cu1000-neo" to prevent conflicts with subsequent boards
such as "cu1000-geo", and so on.
2.Remove "CONFIG_HZ=100" and "mem=32M@0x0" from defconfg.
3.Modify incorrect comments in DT.

v5->v6:
1.Use "stdout-path = "serial2:115200n8"" instead "stdout-path = &uart2" in DT.
2.Remove "console=ttyS2,115200n8" and "CONFIG_CMDLINE_OVERRIDE=y" from defconfg.

v6->v7:
Change my Signed-off-by from "Zhou Yanjie <zhouyanjie@zoho.com>"
to "周琰杰 (Zhou Yanjie) <zhouyanjie@wanyeetech.com>" because
the old mailbox is in an unstable state.
