clocksource/drivers: Add CLINT timer driver

2020-08-20T17:57:29+00:00

We add a separate CLINT timer driver for Linux RISC-V M-mode (i.e.
RISC-V NoMMU kernel).

The CLINT MMIO device provides three things:
1. 64bit free running counter register
2. 64bit per-CPU time compare registers
3. 32bit per-CPU inter-processor interrupt registers

Unlike other timer devices, CLINT provides IPI registers along with
timer registers. To use CLINT IPI registers, the CLINT timer driver
provides IPI related callbacks to arch/riscv.

clocksource/drivers/ingenic: Add support for the Ingenic X1000 OST.

2020-07-23T14:58:09+00:00

X1000 and SoCs after X1000 (such as X1500 and X1830) had a separate
OST, it no longer belongs to TCU. This driver will register both a
clocksource and a sched_clock to the system.

clocksource: Add Low Power STM32 timers driver

2020-06-18T10:19:58+00:00

Implement clock event driver using low power STM32 timers.
Low power timer counters running even when CPUs are stopped.
It could be used as clock event broadcaster to wake up CPUs but not like
a clocksource because each it rise an interrupt the counter restart from 0.

Low power timers have a 16 bits counter and a prescaler which allow to
divide the clock per power of 2 to up 128 to target a 32KHz rate.
