[PATCH] pinctrl: pinctrl-single: add ti,am62l-padconf compatible string

From: Kendall Willis <hidden>
Date: 2026-02-12 21:38:34
Also in: linux-gpio, linux-omap, lkml
Subsystem: pin control subsystem, pin controller - single, the rest · Maintainers: Linus Walleij, Tony Lindgren, Haojian Zhuang, Linus Torvalds

From: Vignesh Raghavendra <vigneshr@ti.com>

Add "ti,am62l-padconf" compatible string for the AM62L SoC, which
requires register configurations to be restored during system resume
after suspend to RAM (RTC only + DDR mode). This reuses the j7200
configuration which includes the PCS_CONTEXT_LOSS_OFF flag needed for
proper restoration.

RTC Only + DDR is a low power mode on the AM62L SoC where most of the
SoC is off except for RTC, which is used as a wakeup source, and DDR
which is in self-refresh.
