From 4910aa198d25e5d1067236560ba34ab12bccc677 Mon Sep 17 00:00:00 2001 From: "Rob Herring (Arm)" Date: Fri, 12 Jun 2026 16:52:16 -0500 Subject: [PATCH] gpio: pisosr: Read "ngpios" as u32 The generic "ngpios" property is encoded as a normal uint32 cell. The pisosr driver stores it in the gpio_chip field, but reading it with a u16 helper does not match the DT property encoding. Read "ngpios" as u32 and keep the existing assignment to the chip field.
