Subject: [PATCH 05/11] Doc: DT: thermal: new irq-mode for trip point
Date: Tue, 16 Oct 2018 16:56:16 +0200	[thread overview]
Message-ID: <20181016145646eucas1p1bd4607c80258df10777ed111cf889fbc~eHqKU_F8K2225422254eucas1p1r@eucas1p1.samsung.com> (raw)
In-Reply-To: <1539701782-26852-1-git-send-email-l.luba@partner.samsung.com>

Thermal trip point gets new flag in DT: irq-mode.
Trip point may have a new explicit flag which indicate
irq support when the temperature is met (so the thermal framework
deos not need set polling for it).
It is useful for 'passive' cooling trip point,
which now will not register for polling the temperature.

Update documentation about irq-mode for trip points.
