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.
Changes since v1:
- Add new compatible ti,am62-eqep
- Fix eqep binding for new compatible, require
power-domains for new compatible
- Fix eQEP DT node to use new ti,am62-eqep compatible

All the nodes seem to be only in disabled mode, is there even a single
board that is actually using this? if so, why isn't it enabled?

I will add pinmux and enable in the board level dts file.

Question about the above... If I enable eQEP at the board level,
there will be pinmux conflicts. So, I could:
1. Leave eQEP disabled
2. Enable eQEP and disable main_uart1 at the board level dts file
3. Enable eQEP in an overlay and also disable main_uart1
Let me know which option works for you.
