arm: zynq: Set proper GIC flags (9f4f5d26) · Commits · 戴 / test

Zynq is able to wake up on any IRQ, so flag it with IRQCHIP_SKIP_SET_WAKE, and we want to mask off the IRQs when going to suspend to avoid transient effects so also flag this with IRQCHIP_MASK_ON_SUSPEND. This is essentially, making the same changes as commit 'ARM: ux500: set proper GIC flags' (sha1: ) for Zynq. Signed-off-by:
