Subject: [PATCH v5 02/11] remoteproc: stm32: Request IRQ with platform device
Date: Tue, 7 Jul 2020 15:31:03 -0600 [thread overview]
Message-ID: <20200707213112.928383-3-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20200707213112.928383-1-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.
