[PATCH 0/2] pwm-tiecap: Add support for AM654 SoCs

[Vignesh R]

Couple of patches to enable pwm-tiecap driver to be used with TI's new
AM654 platforms.

Vignesh R (2):
  dt-bindings: pwm: tiecap: Add TI AM654 SoC specific compatible
  pwm: Kconfig: Enable TI ECAP driver for ARCH_K3

[PATCH 1/2] dt-bindings: pwm: tiecap: Add TI AM654 SoC specific compatible

[Vignesh R]

Add a new compatible string "ti,am654-ecap" to support PWM ECAP IP of
TI AM654 SoC.

[PATCH 2/2] pwm: Kconfig: Enable TI ECAP driver for ARCH_K3

[Vignesh R]

K3 devices have the same ECAP IP as OMAP SoC. Enable driver to be built
for K3 devices.
