Subject: [PATCH v3 6/6] thermal: brcmstb_thermal: Register different ops per process
Date:   Tue, 14 Jan 2020 11:06:07 -0800
Message-Id: <20200114190607.29339-7-f.fainelli@gmail.com>
In-Reply-To: <20200114190607.29339-1-f.fainelli@gmail.com>
References: <20200114190607.29339-1-f.fainelli@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Since we do not have interrupts on BCM7216, we cannot have trip point
crossing, the thermal subsystem expects us to provide a NULL set_trips
operation in that case, so make it possible to provide per-process
thermal_zone_of_device_ops
