    ARM: dts: Configure system timers for ti81xx · 83bd18b4
    Tony Lindgren authored
    We can now init system timers using the dmtimer and 32k counter
    based on only devicetree data and drivers/clocksource timers.
    Let's configure the clocksource and clockevent, and drop the old
    unused platform data.
    
    As we're just dropping platform data, and the early platform data
    init is based on the custom ti,hwmods property, we want to drop
    both the platform data and ti,hwmods property in a single patch.
    
    Since the dmtimer can use both 32k clock and system clock as the
    source, let's also configure the SoC specific default values. The
    board specific dts files can reconfigure these with assigned-clocks
    and assigned-clock-parents as needed.
    
    Note that for ti81xx, also timer1 is of type 2 unlike on am335x
    where timer1 is type1 while the rest of the timers are type 2.
