Subject: [GIT pull] timers/core for v5.19-rc1

Linus,

please pull the latest timers/core branch from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git timers-core-2022-06-05

up to:  57963a92a70b: Merge tag 'timers-v5.19-rc1' of https://git.linaro.org/people/daniel.lezcano/linux into timers/core


Clockevent/clocksource updates:

   - Device tree bindings for MT8186

   - Tell the kernel that the RISC-V SBI timer stops in deeper power states

   - Make device tree parsing in sp804 more robust

   - Dead code removal and tiny fixes here and there

   - Add the missing SPDX identifiers


Thanks,

	tglx
