2022-09-09drm/gma500: Fix (vblank) IRQs not working after suspend/resumeHans de Goede
Fix gnome-shell (and other page-flip users) hanging after suspend/resume because of the gma500's IRQs not working. This fixes 2 problems with the IRQ handling: 1. gma_power_off() calls gma_irq_uninstall() which does a free_irq(), but gma_power_on() called gma_irq_preinstall() + gma_irq_postinstall() which do not call request_irq. Replace the pre- + post-install calls with gma_irq_install() which does prep + request + post. 2. After fixing 1. IRQs still do not work on a Packard Bell Dot SC (Intel Atom N2600, cedarview) netbook. Cederview uses MSI interrupts and it seems that the BIOS re-configures things back to normal APIC based interrupts during S3 suspend. There is some MSI PCI-config registers save/restore code which tries to deal with this, but on the Packard Bell Dot SC this is not sufficient to restore MSI IRQ functionality after a suspend/resume. Replace the PCI-config registers save/restore with pci_disable_msi() on suspend + pci_enable_msi() on resume. Fixing e.g. gnome-shell hanging.

2021-08-10drm/gma500: Convert to Linux IRQ interfacesThomas Zimmermann
Drop the DRM IRQ midlayer in favor of Linux IRQ interfaces. DRM's IRQ helpers are mostly useful for UMS drivers. Modern KMS drivers don't benefit from using it. DRM IRQ callbacks are now being called directly or inlined.

This continues the pattern started in commit cc1ef118fc09 ("drm/irq: Make pipe unsigned and name consistent"). This is applied to the public APIs and driver callbacks, so pretty much all drivers need to be updated to match the new prototypes.
