Subject: [PATCH 2/4] arm: dts: sunplus: add PWM, watchdog and MMC nodes to SP7021 DTSI
Date: Thu, 17 Sep 2026 10:26:30 +0200 [thread overview]
Message-ID: <20260917082632.626614-3-ag@ffroot.co.za> (raw)
In-Reply-To: <20260917082632.626614-1-ag@ffroot.co.za>
Add device nodes for the peripherals that have upstream drivers:
- PWM controller
- Watchdog controller
- eMMC controller
Also add a label to the gpio-leds node so board DTS files can override it.
