2019-11-18	remoteproc: stm32: fix probe error case	Fabien Dessenne	1	-2/+15
	If the rproc driver is probed before the mailbox driver and if the rproc Device Tree node has some mailbox properties, the rproc driver probe shall be deferred instead of being probed without mailbox support.

2019-11-14	remoteproc: stm32: wakeup the system by wdg irq	Fabien Dessenne	1	-0/+45
	If the device node defines the 'wakeup-source' property, use the WDG exti IRQ as a wakeup source of the system.

2019-11-08	remoteproc: stm32: use workqueue to treat mailbox callback	Arnaud Pouliquen	1	-5/+33
	The mailbox callback is under interrupt context. A consequence is that RPMsg Callbacks are also in interrupt context. Create workqueue to treat the callbacks in normal context. Signed-off-by: Arnaud Pouliquen <arnaud.pouliquen@st.com> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>

2019-08-26	remoteproc: stm32: clear MCU PDDS at firmware start	Fabien Dessenne	1	-0/+11
	When remoteproc stops a firmware, it sets the MCU PDDS flag, allowing the platform to reach the Standby power mode if needed. Symmetrically, clear this flag before running a firmware. This fixes the issue where the system goes to Standby mode when the MCU crashes while MPU is in CSTOP mode.

2019-07-08	remoteproc: stm32: fix building without ARM SMCC	Arnd Bergmann	1	-1/+1
	When compile testing this driver without SMCC support enabled, we get a link error: drivers/remoteproc/stm32_rproc.o: In function `stm32_rproc_start': stm32_rproc.c:(.text+0x776): undefined reference to `__arm_smccc_smc' drivers/remoteproc/stm32_rproc.o: In function `stm32_rproc_stop': stm32_rproc.c:(.text+0x92c): undefined reference to `__arm_smccc_smc' Make the actual call to arm_smccc_smc conditional on the Kconfig symbol controlling its implementation.

2019-06-29	remoteproc: stm32: add an ST stm32_rproc driver	Fabien Dessenne	1	-0/+628
	This patch introduces a new remoteproc driver to control Cortex-M4 co-processor of the STM32 family. It provides with the following features: - start and stop - dedicated co-processor memory regions registration - coredump and recovery Signed-off-by: Fabien Dessenne <fabien.dessenne@st.com> Signed-off-by: Ludovic Barre <ludovic.barre@st.com> Signed-off-by: Loic Pallardy <loic.pallardy@st.com> Signed-off-by: Arnaud Pouliquen <arnaud.pouliquen@st.com> [bjorn: Fixup of dev_dbg types and cast of int to pointer in mbox send] Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
