From 4fd8f47e7e5b64a74b60f23c2e08ba8234d659d1 Mon Sep 17 00:00:00 2001 From: Grygorii Strashko Date: Fri, 14 Aug 2015 15:20:29 +0300 Subject: irqchip/crossbar: Restore the mask on suspend behaviour From: Grygorii Strashko commit 4fd8f47e7e5b64a74b60f23c2e08ba8234d659d1 upstream. The ARM GIC requires that all interrupts which are not used as a wakeup source have to be masked during suspend. The conversion of the crossbar irqchip to hierarchical irq domains failed to mark the crossbar irqchip with the IRQCHIP_MASK_ON_SUSPEND flag and therefor broke the suspend requirement of the GIC. Before the conversion the flags were visible because the GIC was the top level irqchip. After the conversion the crossbar irqchip is the top level irq chip whose flags are evaluated in suspend_device_irq(). As the flag is not set the masking of the non-wakeup irqs is not invoked which breaks suspend. Add the IRQCHIP_MASK_ON_SUSPEND flag to the crossbar irqchip, so the GIC interrupts get masked properly.
