Commite428e250fd("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.

* Texas Instruments OMAP
|
|
|
|
OMAP is currently using a static file per SoC family to describe the
|
|
IPs present in the SoC.
|
|
On top of that an omap_device is created to extend the platform_device
|
|
capabilities and to allow binding with one or several hwmods.
|
|
The hwmods will contain all the information to build the device:
|
|
address range, irq lines, dma lines, interconnect, PRCM register,
|
|
clock domain, input clocks.
|
|
For the moment just point to the existing hwmod, the next step will be
|
|
to move data from hwmod to device-tree representation.
|
|
|
|
|
|
Required properties:
|
|
- compatible: Every devices present in OMAP SoC should be in the
|
|
form: "ti,XXX"
|
|
- ti,hwmods: list of hwmod names (ascii strings), that comes from the OMAP
|
|
HW documentation, attached to a device. Must contain at least
|
|
one hwmod.
|
|
|
|
Optional properties:
|
|
- ti,no_idle_on_suspend: When present, it prevents the PM to idle the module
|
|
during suspend.
|
|
- ti,no-reset-on-init: When present, the module should not be reset at init
|
|
- ti,no-idle-on-init: When present, the module should not be idled at init
|
|
- ti,no-idle: When present, the module is never allowed to idle.
|
|
|
|
Example:

|
|
compatible = "ti,omap4-spinlock";

ti,hwmods = "spinlock";
