[PATCH v7 1/6] MIPS: Ingenic: Initial X1000 support.

周琰杰 (Zhou Yanjie)
2019-12-09T13:01:14Z

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.

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

v2->v3:
Drop the 'apb' node.

v3->v4:
Adjust the node order to make it consistent with
other Ingenic boards.

v4->v5:
No change.

v5->v6:
No change.

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.
