Subject: [PATCH] thermal: Share THERMAL_NO_LIMIT between kernel and DT bindings
Date: Wed, 21 Oct 2026 15:42:43 +0200	[thread overview]
Message-ID: <20261021134243.35103-1-daniel.lezcano@oss.qualcomm.com> (raw)

THERMAL_NO_LIMIT is defined separately in the thermal core and the DT
bindings, using different expressions for the same no-limit sentinel.

Define it as 0xffffffff in the DT bindings header and include that
header from linux/thermal.h. Remove the duplicate kernel definition so
both interfaces use the same unsigned 32-bit value while preserving
the existing DT encoding.
