Hi all, these are the remaining unapplied patches of the ARM HDLCD patch series. Changes in v7: - rebased on b61ed421d2c85b5b106c63f2c14f8aa162b282f0; - turn more printk and panic into early_printk and early_panic. Changes in v6: - rebased on 77d3a1db3196b1b5864469f8d3f41d496800c795; - remove useless initializations to NULL in lfb_init; - more compact checks in...

...obe connectors while runtime suspended. E.g. for a PCI device, probing might require mmio access, which isn't possible outside of power state D0. There are no ->detect hooks declared in drivers/gpu/drm/arm/, so it's unclear to me whether you're able to probe during runtime suspend. hdlcd_drv.c and malidp_drv.c both enable output polling. Output polling is only necessary if you don't get HPD interrupts. You're not disabling polling upon runtime suspend. Thus, if a runtime PM ref is acquired during polling (such as in a ->detect hook), the GPU will be runtime resumed ev...

That's because the drivers in drivers/gpu/drm/arm do not have connectors, they are only the CRTC part of the driver. Both hdlcd and mali-dp use the component framework to locate an encoder in device tree that will then provide the connectors. > > hdlcd_drv.c and malidp_drv.c both enable output polling.
