[PATCH 4.19 034/280] ARM: dts: Configure clock parent for pwm vibra

From: Greg Kroah-Hartman
Date: Fri Mar 22 2019 - 08:48:45 EST


4.19-stable review patch. If anyone has any objections, please let me know.

------------------

[ Upstream commit 0840242e887586268f665bf58d5e1a7d6ebf35ed ]

Commit 84badc5ec5fc ("ARM: dts: omap4: Move l4 child devices to probe
them with ti-sysc") moved some omap4 timers to probe with ti-sysc
interconnect target module. Turns out this broke pwm-omap-dmtimer
for reparenting of the timer clock.

With ti-sysc, we can now configure the clock sources in the dts with
assigned-clocks and assigned-clock-parents.
