Judith Mendez 988609f2aa counter: ti-eqep: Allow eQEP driver to be built for K3 devices
TI K3 SoC's support eQEP hardware, so add ARCH_K3 to the depends
so the TI eQEP driver can be built for K3 devices.

help
Enables support for the i8254 interface library functions. The i8254
interface library provides functions to facilitate communication with
interfaces compatible with the venerable Intel 8254 Programmable
Interval Timer (PIT). The Intel 825x family of chips was first
released in the early 1980s but compatible interfaces are nowadays
typically found embedded in larger VLSI processing chips and FPGA
components.
If built as a module its name will be i8254.

This enables counter device support through the Generic Counter
interface. You only need to enable this, if you also want to enable
one or more of the counter device drivers below.

Say yes here to build support for the ACCES 104-QUAD-8 quadrature
encoder counter/interface device family (104-QUAD-8, 104-QUAD-4).
A counter's respective error flag may be cleared by performing a write
operation on the respective count value attribute. The 104-QUAD-8
counters may be set either directly or via the counter's preset
attribute.
The base port addresses for the devices may be configured via the base
array module parameter. The interrupt line numbers for the devices may
be configured via the irq array module parameter.
