Subject: [PATCH V2] thermal/drivers/qoriq: fix getting tmu range
Date: Mon, 26 Feb 2024 08:36:57 +0800 [thread overview]
Message-ID: <20240226003657.3012880-1-peng.fan@oss.nxp.com> (raw)
From: Peng Fan <peng.fan@nxp.com>
TMU Version 1 has 4 TTRCRs, while TMU Version >=2 has 16 TTRCRs.
So limit the len to 4 will report "invalid range data" for i.MX93.
This patch drop the local array with allocated ttrcr array and
able to support larger tmu ranges.
Fixes: f12d60c81fce ("thermal/drivers/qoriq: Support version 2.1")
