Subject: [PATCH v4 02/11] remoteproc: stm32: Request IRQ with platform device
Date: Mon, 1 Jun 2020 11:55:43 -0600 [thread overview]
Message-ID: <20200601175552.22286-3-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20200601175552.22286-1-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.
