OST is the OS Timer, a 64-bit timer/counter with buffered reading.
SoCs before the JZ4770 had (if any) a 32-bit OST; the JZ4770 and
JZ4780 have a 64-bit OST.
This driver will register both a clocksource and a sched_clock to
the
system.

Notes:
v5: New patch
v6: - Get rid of SoC IDs; pass pointer to
ingenic_ost_soc_info as
devicetree match data instead.
- Use device_get_match_data() instead of the of_* variant
- Handle error of dev_get_regmap() properly
v7: Fix section mismatch by using
builtin_platform_driver_probe()
v8: builtin_platform_driver_probe() does not work anymore in
4.20-rc6? The probe function won't be called. Work around
this
for now by using late_initcall.
Did anyone notice this ? Either something is wrong with the driver, or
with the kernel core. Hacking around it seems like the worst possible
"solution".
I can confirm it still happens on 5.0-rc3.
Just to explain what I'm doing:
My ingenic-timer driver probes with builtin_platform_driver_probe (this
works),
and then calls of_platform_populate to probe its children. This driver,
ingenic-ost, is one of them, and will fail to probe with
builtin_platform_driver_probe.
