[PATCH 5.4 037/191] clocksource/drivers/timer-of: Use unique device name instead of timer

[Greg Kroah-Hartman]

From: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>

[ Upstream commit 4411464d6f8b5e5759637235a6f2b2a85c2be0f1 ]

If a hardware-specific driver does not provide a name, the timer-of core
falls back to device_node.name.  Due to generic DT node naming policies,
that name is almost always "timer", and thus doesn't identify the actual
timer used.

Fix this by using device_node.full_name instead, which includes the unit
addrees.

Example impact on /proc/timer_list:

    -Clock Event Device: timer
    +Clock Event Device: timer@fcfec400
