Subject: [PATCH v8 4/4] MIPS: Ingenic: Add YSH & ATIL CU Neo board support.
Date: Tue, 10 Dec 2019 20:02:43 +0800	[thread overview]
Message-ID: <1575979363-25956-5-git-send-email-zhouyanjie@wanyeetech.com> (raw)
In-Reply-To: <1575979363-25956-1-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.

Signed-off-by: 周琰杰 (Zhou Yanjie) <zhouyanjie@wanyeetech.com>

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.
    
    v7->v8:
    Merge [6/6] in v7 to this patch.
