Subject: [PATCH v5 0/3] Add SMP/SMT support for Ingenic sysost driver.

1.On the hardware of X2000 SoC, the OST has been split into
two parts, two 32bit timers for clockevent and one 64bit
timer for clocksource (with different addresses), so it
not appropriate to use only one "ingenic,x2000-ost", just
remove it, then introduce "ingenic,x2000-ost32" and
"ingenic,x2000-ost64".
2.The OST in Ingenic XBurst®2 SoCs has a global timer and
up to 16 event timers, add support for the event timers.
3.Add dt-bindings and compatible strings for the X1600 SoC,
the X1700 SoC, the X1830 SoC, the X2000 SoC, the X2500 SoC.

v4->v5:
Fix warnings reported-by: kernel test robot <[email protected]>.

周琰杰 (Zhou Yanjie) (3):
dt-bindings: timer: Remove unreasonable binding.
dt-bindings: timer: Add bindings for new Ingenic SoCs.
clocksource: Ingenic: Add SMP/SMT support for sysost driver.

Hi guys,


Please ignore this series, according to Paul's suggestion, we will use a
new driver to implement these functions.


Thanks and beset regards!
