[PATCH v5 0/2] Convert TI dmtimer binding to yaml

[Tony Lindgren]

Hi,

Here are v5 changes for TI dmtimer.

Regards,

Tony


Changes since v1:

- Improve yaml for various checks based on comments from Krzysztof
  and Nishanth

- Add checks for am4 timer as pointed out by Krzysztof and Rob

- Split am6 additions into a separate patch as suggested by Krzysztof

Changes since v2:

- Improve yaml for more checks based on comments from Grygorii and
  Krzysztof

Changes since v3:

- Simplify constraints for reg, clocks and clock-names as suggested by
  Krzysztof

- Use version number for patches too as suggested by Rob

Changes since v4:

- Drop duplicated items as noted by Krzysztof

[PATCH v5 1/2] dt-bindings: timer: Update TI timer to yaml

[Tony Lindgren]

Let's update the TI timer binding to use yaml. As this binding is specific
to the TI dual-mode timers also known as dm-timers, let's use file name
ti,timer-dm.yaml to avoid confusion with other timers.

We add checks for the deprecated ti,hwmods property as done for other TI
device driver bindings earlier.

We also correct the issue with the old binding that was out of date for
several properties.

The am43 related timers are undocumented, but compatible with the am3
timers. Let's add the am43 timers too.

The dm814 and dm816 timers are missing, let's add them.

Some timers on some SoCs are dual mapped, like the ABE timers on omap4
and 5. The reg property maxItems must be updated to 2.

The timer clocks can be managed by the parent interconnect target module
with no clocks assigned for the timer node. And in some cases, the SoC may
need to configure additional system clock for the timer in addition to the
functional clock.

The clock names are optional and not specific to the comptible property.
For example, dra7 timers on l3 interconnect do not need clock-names, while
the timers on dra7 l4 interconnect need them with both being compatible
with ti,omap5430-timer.

[PATCH v5 2/2] dt-bindings: timer: Add compatible for am6 for TI timer-dm

[Tony Lindgren]

Let's add compatible for ti,am654-timer for TI am64, am65 and j72 SoCs.
As the timer hardware is the same between am64, am65 and j72 we use the
compatible name for the earliest SoC with this timer.

The timer interrupts are not routable for the operating system for some
timers on am6. Let's make sure the interrupts are configured for the
timers on all other SoCs.

[PATCH v5 2/2] dt-bindings: timer: Add compatible for am6 for TI timer-dm

[Tony Lindgren]

Let's add compatible for ti,am654-timer for TI am64, am65 and j72 SoCs.
As the timer hardware is the same between am64, am65 and j72 we use the
compatible name for the earliest SoC with this timer.

The timer interrupts are not routable for the operating system for some
timers on am6. Let's make sure the interrupts are configured for the
timers on all other SoCs.
