[PATCH v6 01/12] MIPS: Ingenic: Initial X1000 support.
From: Zhou Yanjie <hidden>
Date: 2019-11-29 08:50:35
Also in:
linux-mips, lkml
Subsystem:
ingenic jz47xx socs, mips, the rest · Maintainers:
Paul Cercueil, Thomas Bogendoerfer, Linus Torvalds
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 <redacted>

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.
