Subject: [PATCH] ARM: dts: imx7ulp: add "tpm6" pwm node to i.MX7ULP
Date: Wed, 21 Oct 2026 10:45:59 +0200 [thread overview]
Message-ID: <20261021084602.121087-1-sympthicode@gmail.com> (raw)
From: Krzysztof Kaszubski <simpthicode@gmail.com>
Add the Low Power Timer/Pulse Width Modulation Module 6 (TPM6)
node to the i.MX 7ULP device tree.
TPM6 is located in the Application Domain (Cortex-A7) at base
address 0x40a10000. This enables PWM and timer support for
peripherals connected to this domain, such as display backlight
controllers.
