Subject: [PATCH v7 4/6] MIPS: Ingenic: Initial YSH & ATIL CU Neo board support.
Date: Mon, 9 Dec 2019 21:00:36 +0800 [thread overview]
Message-ID: <1575896438-9562-5-git-send-email-zhouyanjie@wanyeetech.com> (raw)
In-Reply-To: <1575896438-9562-1-git-send-email-zhouyanjie@wanyeetech.com>
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.
