Subject: [PATCH v1 4/5] thermal/drivers/mediatek/lvts_thermal: Add SoC based golden Temp
Date: Sun, 26 Oct 2025 13:21:33 +0100 [thread overview]
Message-ID: <20251026122143.71100-5-linux@fw-web.de> (raw)
In-Reply-To: <20251026122143.71100-1-linux@fw-web.de>
From: Frank Wunderlich <frank-w@public-files.de>
Add SoC based golden temp for invalid efuse data.
This is a preliminary patch for mt7987 support where goldentemp is
slightly higher than other SOCs.
