This patch series adds eQEP DT nodes for K3 Sitara devices:
- AM62x
- AM62ax
- AM62px
- AM64x
Also enable eQEP to be built as a module for ARCH_k3.

2.43.2
Add eQEP DT nodes 0-2 for AM62A7 SoC.
Since external hardware was needed to test eQEP, the DT nodes
for eQEP were not included in the introductory commit. Now that
eQEP has been validated, add nodes to k3-am62a-main.dtsi.
