Haavard Skinnemoen 3aa04f1b07 atmel_lcdfb: disable LCD and DMA engines when suspending ... When suspending the system with atmel_lcdfb enabled, I sometimes see this: atmel_lcdfb atmel_lcdfb.0: FIFO underflow 0x10 Which can be explained by the fact that we're not stopping the LCD controller and its DMA engine when suspending, we're just gating the clocks to them. There's another potential issue which may be harder to trigger but much more nasty: If we gate the clocks at _just_ the right moment, e.g. when the DMA engine is doing a bus transaction, we may cause the DMA engine to violate the system bus protocol and cause a lockup. Avoid these issues by shutting down the LCD controller before entering suspend (and restarting it when resuming). This prevents the underrun from happening in the first place, and prevents whatever nastiness is happening when the bus clock stops in the middle of a DMA transfer.
