Subject: [PATCH 2/2] ARM: dts: imx6qdl: phycore-som: Add custom volt/freq table
Date: Wed, 23 Sep 2026 09:05:05 +0200 [thread overview]
Message-ID: <20260923070505.494949-3-primoz.fiser@norik.com> (raw)
In-Reply-To: <20260923070505.494949-1-primoz.fiser@norik.com>
From: Yunus Bas <y.bas@phytec.de>
The PHYTEC phyCORE-i.MX6QDL SOM-modules are operating with a slightly
different voltage and frequency values in contrast to the generic
i.MX6Q/DL tables. The values have been adjusted to achieve the most
stable condition for the PHYTEC-modules. Introduce imx6q- and
imx6dl-phycore dtsi files with the modified power tables.
