Subject[PATCH V2] arm64: dts: ti: k3-pinctrl: Introduce debounce select mux macros
Date
Introduce the debounce select mux macros to allow folks to setup
debounce configuration for pins. Each configuration selected maps
to a specific timing register as documented in appropriate Technical
Reference Manual (example:[1]).

[1] AM625x TRM (section 6.1.2.2): https://www.ti.com/lit/pdf/spruiv7

Changes since V1:
- I have'nt picked up Krystoff's ack since the file modified is now different.
- Changes now applied to k3-pinctrl.h instead of the ABI header that is
now set up to be deleted in v6.5-rc1.

V1: https://lore.kernel.org/linux-devicetree/20230308084309.396192-1-nm@ti.com/
