2019-07-10	mailbox: imx: Clear GIEn bit at shutdown	Daniel Baluta	1	-2/+2
	GIEn is enabled at startup for RX doorbell mailboxes so we need to clear the bit at shutdown in order to avoid leaving the interrupt line enabled.

2019-03-11	mailbox: imx: keep MU irq working during suspend/resume	Anson Huang	1	-2/+2
	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.

	The i.MX Messaging Unit is a two side block which allows applications implement communication over this sides. The MU includes the following features: - Messaging control by interrupts or by polling - Four general-purpose interrupt requests reflected to the other side - Three general-purpose flags reflected to the other side - Four receive registers with maskable interrupt - Four transmit registers with maskable interrupt Reviewed-by: Vladimir Zapolskiy <vz@mleia.com> Reviewed-by: Dong Aisheng <aisheng.dong@nxp.com> Signed-off-by: Oleksij Rempel <o.rempel@pengutronix.de> Signed-off-by: Jassi Brar <jaswinder.singh@linaro.org>
