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
