[PATCH v3 0/3] Enable rk3588 timer support

[Cristian Ciocaltea]

This patchset enables Rockchip RK3588/RK3588S SoC timer support.
While here, it also handles a minor DT binding issue related to RK3288.

Changes in v3:
 - Updated commit description in patch 1, per Krzysztof's review
 - Added Acked-by tag from Krzysztof in patch 2
 - v2: https://lore.kernel.org/lkml/20230418120624.284551-1-cristian.ciocaltea@collabora.com/

Changes in v2:
 - Added Reviewed-by tag from Heiko in patches 1 & 2
 - Update patch 3 according to Johan's review
 - v1: https://lore.kernel.org/lkml/20230418095344.274025-1-cristian.ciocaltea@collabora.com/

[PATCH v3 1/3] dt-bindings: timer: rockchip: Drop superfluous rk3288 compatible

[Cristian Ciocaltea]

The compatible string for Rockchip RK3288 is wrongly provided in the
'enum' item, in addition to the subsequent 'const', which allows the
usage of an incorrect specification:

  compatible = "rockchip,rk3288-timer", "rockchip,rk3288-timer";

As the rk3288 string is also specified in the top-most 'const' item, the
binding already allows the usage of the correct variant:

  compatible = "rockchip,rk3288-timer";

Drop the unwanted rk3288 entry from the enum.

I tested this on a QuartzPro64 dev board, I applied your series top of my tree:
Collabora's rk3588 + some DT patches to add support for the qp64 board.

Here is the output from the commands you told me to try:

bash-5.1# grep rk_timer /sys/bus/clockevents/devices/*/current_device
/sys/bus/clockevents/devices/broadcast/current_device:rk_timer

bash-5.1# grep -B3 -A14 'Device: rk_timer' /proc/timer_list

Tick Device: mode:     1
Broadcast device
Clock Event Device: rk_timer
 max_delta_ns:   178956969070
 min_delta_ns:   1000
 mult:           51539608
 shift:          31
 mode:           3
 next_event:     150944000000 nsecs
 set_next_event: rk_timer_set_next_event
 shutdown:       rk_timer_shutdown
 periodic:       rk_timer_set_periodic
 event_handler:  tick_handle_oneshot_broadcast

 retries:        0

tick_broadcast_mask: ff

bash-5.1# head -1 /proc/interrupts ; grep rk_timer /proc/interrupts;
sleep 10; grep rk_timer /proc/interrupts
           CPU0       CPU1       CPU2       CPU3       CPU4       CPU5
      CPU6       CPU7
 25:        742        210         52         49       2197       1640
      1089       2341     GICv3 321 Level     rk_timer
 25:        754        222         52         49       2252       1727
      1146       2404     GICv3 321 Level     rk_timer

So it looks like this is working.

Thanks for your work.

You did the work, I try to help...

BTW, I'll test the PWM fan patch (ported to QP64 board) iff I can find
a fan with the same connector...
