Subject: [PATCH v2 1/4] MIPS: Ingenic: initial X1000 support.
Date: Sat, 23 Nov 2019 10:32:21 +0800	[thread overview]
Message-ID: <1574476344-62631-2-git-send-email-zhouyanjie@zoho.com> (raw)
In-Reply-To: <1574476344-62631-1-git-send-email-zhouyanjie@zoho.com>

Support the Ingenic X1000 SoC using the code under arch/mips/jz4740.
This is left unselectable in Kconfig until a X1000 based board is
added in a later commit.

Signed-off-by: Zhou Yanjie <zhouyanjie@zoho.com>

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