mailbox: stm32-ipcc: check invalid irq

2019-06-15T09:52:55+00:00

[ Upstream commit 68a1c8485cf83734d4da9d81cd3b5d2ae7c0339b ] On failure of_irq_get() returns a negative value or zero, which is not handled as an error in the existing implementation. Instead of using this API, use platform_get_irq() that returns exclusively a negative value on failure. Also, do not output an error log in case of defer probe error.

mailbox: imx: keep MU irq working during suspend/resume

2019-03-11T07:51:43+00:00

During noirq suspend phase, mailbox MU irq will be masked but many drivers still need to communicate with system controller firmware via mailbox, if MU irq is masked, it will cause RPC timeout as below: [ 23.372103] imx-scu scu: RPC send msg timeout Setting MU irq to be wakeup source is NOT working as GIC driver does NOT have .irq_set_wake implemented, so to support suspend/resume, just make imx mailbox driver NOT suspend, since MU is always a wakeup source on i.MX platforms with system controller inside, and its power/clock is maintained by system controller, mailbox driver no need to manage them.
