From f91a731ffc3b9eed7e3091d59620b292c448e9c1 Mon Sep 17 00:00:00 2001 From: Abel Vesa Date: Wed, 21 Feb 2024 15:04:25 +0200 Subject: [PATCH] arm64: dts: qcom: sm8550: Fix SPMI channels size [ Upstream commit 77dd1e50ffcba33c3195ae4fc78f354368ddacb2 ] The actual size of the channels registers region is 4MB, according to the documentation. This issue was not caught until now because the driver was supposed to allow same regions being mapped multiple times for supporting multiple buses. Thie driver is using platform_get_resource_byname() and devm_ioremap() towards that purpose, which intentionally avoids devm_request_mem_region() altogether.
