Subject: [PATCH v3 3/3] arm64: dts: ti: k3-pinctrl: Add the remaining macros
Date: Tue, 2 Sep 2025 12:49:17 +0530	[thread overview]
Message-ID: <20250902071917.1616729-4-a-kaur@ti.com> (raw)
In-Reply-To: <20250902071917.1616729-1-a-kaur@ti.com>

Add the drive stregth, schmitt trigger enable macros to pinctrl file.
Add the missing macros for DeepSleep configuration control referenced
from "Table 14-6172. Description Of The Pad Configuration Register Bits"
in AM625 TRM[0].
Add some DeepSleep macros to provide combinations that can be used
directly in device tree files example PIN_DS_OUTPUT_LOW that
configures pin to be output and also sets its value to 0.
