| Subject: gpio: em: Enable mask on suspend |
| |
| Now when lazy interrupt disable has been enabled in the driver |
| then extend the code to set IRQCHIP_MASK_ON_SUSPEND which tells |
| the core that only IRQs marked as wakeups need to stay enabled |
| during Suspend-to-RAM. |
| |
| Tested on the KZM9D board with GPIO-keys. |
