Subject: [PATCH 0/2] arm64: dts: agilex5: add support for debug daughter card
Date: Fri, 8 May 2026 18:57:46 +0800 [thread overview]
Message-ID: <cover.1778237639.git.adrian.ho.yin.ng@altera.com> (raw)
The Agilex5 SoCDK supports an optional debug daughter card that requires
a dedicated device tree variant due to differences in peripheral
connectivity compared to the standard SoCDK configuration.
When the debug daughter card is fitted:
- gpio0 and gmac2 are disabled
- gmac0 is enabled with RGMII PHY connectivity
- spi0 is enabled with a <device> peripheral at chip select 0
- The HPS LED is rewired from gpio0/porta to gpio1/portb
The new DTS inherits from socfpga_agilex5_socdk.dts and overrides only
the nodes that differ, keeping the delta minimal.
