Subject: [PATCH v6 0/4] Update the thermal support for imx93
Date: Thu, 30 Apr 2026 10:53:29 +0800 [thread overview]
Message-ID: <20260430-imx93_tmu-v6-0-485459d7b54f@nxp.com> (raw)
The TMU (Thermal Monitoring Unit) on the i.MX93 requires specific
configurations and workarounds that differ from previous implementations.
So, using the 'fsl,qoriq-tmu' compatible string is not appropriate.
To address this, a dedicated compatible string and corresponding driver
changes need to be introduced to properly support the i.MX93 TMU.
