From 6dba9b7268cc50166bce47608670192fd874e363 Mon Sep 17 00:00:00 2001 From: Biju Das Date: Sat, 28 Mar 2026 09:05:45 +0000 Subject: [PATCH] pinctrl: renesas: rzg2l: Fix incorrect PUPD register offset for high pins during suspend/resume MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When saving/restoring pull-up/down register state during suspend/resume, the second PUPD register access was incorrectly using the same base offset as the first, effectively reading/writing the same register twice instead of the adjacent one. Add the correct + 4 byte offset to the second RZG2L_PCTRL_REG_ACCESS32 call so that pupd[1][port] is properly saved and restored from the next 32-bit register in the PUPD register pair, covering pins 4–7 of ports with 4 or more pins.
