From 3c896a2e21cc5a579233cc10542d77c8ae0a6d81 Mon Sep 17 00:00:00 2001 From: Josua Mayer Date: Mon, 28 Sep 2026 19:34:01 +0200 Subject: [PATCH] arm64: dts: renesas: Add support for solidrun hb-ripple with rzg2lc som Add support for the SolidRun HummingBoard Ripple [2] with RZ/G2LC SoM [1]. The HummingBoard Ripple is a reduced version of HummingBoard Pulse, featuring: - 2x USB-2.0 Type-A connector - 1x 100Mbps RJ45 Ethernet - micro-HDMI connector - microSD connector - mini-PCI-E connector with SIM slot supporting USB-2.0 interface - MIPI-CSI Camera Connector (not described without specific camera) - RTC with backup battery The carrier board is identical between RZ/G2L, RZ/G2LC, RZ/G2UL and RZ/V2L SoMs, yet only the RZ/G2LC combination has a product page [2]. RZ/G2LC SoM shares SCIF2 pins between on-SoM Bluetooth and carrier board. Provide dt overlay changing pin function from uart to GPIO LED control. While the variant being supported here is named "Ripple", the overlay still carries the "pulse" suffix as it would fit all its variants. Descriptions for eMMC and microSD are shared with G2L SoM and HummingBoard IIoT.
