[PATCH 0/5] ARM: dts: stm32: add counter nodes on stm32mp13 and stm32mp15

[Fabrice Gasnier]

Counter driver originally had support limited to quadrature interface
and simple counter. It has been improved[1], so populate and enable
stm32 timer counter nodes on stm32mp13 and stm32mp15.

[PATCH 1/5] ARM: dts: stm32: populate all timer counter nodes on stm32mp13

[Fabrice Gasnier]

Counter driver originally had support limited to quadrature interface
and simple counter. It has been improved[1], so add the remaining
stm32 timer counter nodes.

[PATCH 3/5] ARM: dts: stm32: add counter subnodes on stm32mp135f-dk

[Fabrice Gasnier]

Enable the counter nodes without dedicated pins. With such configuration,
the counter interface can be used on internal clock to generate events.
