Subject: [PATCH v2 02/12] remoteproc: stm32: Request IRQ with platform device
Date: Fri, 24 Apr 2020 14:24:55 -0600	[thread overview]
Message-ID: <20200424202505.29562-3-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20200424202505.29562-1-mathieu.poirier@linaro.org>

Request IRQ with platform device rather than remote proc in order to
call stm32_rproc_parse_dt() before rproc_alloc().  That way we can
know whether we need to synchronise with the MCU or not.
