[PATCH v6 0/3] clocksource/drivers/atcpit100: Add andestech atcpit100 timer
From: Greentime Hu
Date: Mon Jan 15 2018 - 00:57:57 EST
ATCPIT100 is often used on the Andes architecture,
This timer provide 4 PIT channels. Each PIT channel is a
multi-function timer, can be configured as 32,16,8 bit timers
or PWM as well.
For system timer it will set channel 1 32-bit timer0 as clock
source and count downwards until underflow and restart again.
It also set channel 0 32-bit timer0 as clock event and count
downwards until condition match. It will generate an interrupt
for handling periodically.
Changes in v6:
- To select TIMER_OF in drivers/clocksource/Kconfig instead of arch/nds32/Kconfig
- Refine Kconfig
- Update license format to SPDX-License-Identifier
