From 0968c81ce9c4b42cfaaee15de53c665064fe7ee3 Mon Sep 17 00:00:00 2001 From: Ryan Wanner Date: Mon, 5 Jan 2026 10:59:56 +0100 Subject: [PATCH] pinctrl: at91-pio4: Add sama7d65 pio4 support Add sama7d65 compatibility string. Sama7d65 does not have a full last bank of PIO lines similar to the Sama7g54 SoC. Sama7d65 only has 14 lines on the last PIO bank not the full 32; adjusting the SoC attributes accordingly.
