    Subject[PATCH AUTOSEL 4.19 20/79] clocksource/drivers/timer-of: Use unique device name instead of timer
    Date
    From: Geert Uytterhoeven <geert+renesas@glider.be>

    [ 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
