ARM: dts: Use 32KiHz oscillator on devkit8000

2022-03-08T18:12:49Z

[ Upstream commit 8840f5460a23759403f1f2860429dcbcc2f04a65 ] Devkit8000 board seems to always used 32k_counter as clocksource. Restore this behavior. If clocksource is back to 32k_counter, timer12 is now the clockevent source (as before) and timer2 is not longer needed here. This commit fixes the same issue observed with commit 23885389dbbb ("ARM: dts: Fix timer regression for beagleboard revision c") when sleep is blocked until hitting keys over serial console.

ARM: dts: Fix timer regression for beagleboard revision c

2022-02-16T11:56:21Z

[ Upstream commit 23885389dbbbbc698986e77a45c1fc44a6e3632e ] Commit e428e250fde6 ("ARM: dts: Configure system timers for omap3") caused a timer regression for beagleboard revision c where the system clockevent stops working if omap3isp module is unloaded. Turns out we still have beagleboard revisions a-b4 capacitor c70 quirks applied that limit the usable timers for no good reason. This also affects the power management as we use the system clock instead of the 32k clock source. Let's fix the issue by adding a new omap3-beagle-ab4.dts for the old timer quirks. This allows us to remove the timer quirks for later beagleboard revisions. We also need to update the related timer quirk check for the correct compatible property.

clocksource/drivers/dw_apb_timer_of: Fix probe failure

2021-12-14T09:57:23Z

commit a663bd19114d79f0902e2490fc484e5a7419cdc2 upstream. The driver refuses to probe with -EINVAL since the commit 5d9814df0aec ("clocksource/drivers/dw_apb_timer_of: Add error handling if no clock available"). Before the driver used to probe successfully if either "clock-freq" or "clock-frequency" properties has been specified in the device tree. That commit changed if (A && B) panic("No clock nor clock-frequency property"); into if (!A && !B) return 0; That's a bug: the reverse of `A && B` is '!A || !B', not '!A && !B' Signed-off-by: Vadim V.
