[PATCH v2 1/2] arm64: dts: ti: k3-pinctrl: Introduce deep sleep macros

From: Siddharth Vadapalli
Date: Thu Dec 05 2024 - 07:02:20 EST


The behavior of pins in deep sleep mode can be configured by programming
the corresponding bits in the respective Pad Configuration register. Add
macros to support this.

v1:
https://lore.kernel.org/r/20241112115650.988943-2-s-vadapalli@xxxxxx
Changes since v1:
- Rebased on next-20241204.

While Rob had suggested dropping the zero defines at:
https://lore.kernel.org/r/20241115154822.GA2954187-robh@xxxxxxxxxx/
I had pointed out the inconsistency with existing convention at:
https://lore.kernel.org/r/5b35c736-74d6-4fe9-ae82-272dc2e98b82@xxxxxx/
asking for Rob's opinion. Since I didn't receive a reply, I assumed that
the patch is fine in terms of being consistent and hence haven't dropped
the zero defines in the current version.

Regards,
Siddharth.
