2022-09-18drm/gma500: Refactor backlight support (v2)Hans de Goede
Refactor backlight support so that the gma_backlight_enable() / gma_backlight_disable() / gma_backlight_set() functions used by the Opregion handle will also work if no backlight_device gets registered. This is a preparation patch for not registering the gma500's own backlight device when acpi_video should be used, since registering 2 backlight devices for a single display really is undesirable. Since the acpi-video interface often uses the OpRegion we need to keep the OpRegion functional even when dev_priv->backlight_device is NULL. As a result of this refactor the actual backlight_device_register() call is moved to the shared backlight.c code and all #ifdefs related to CONFIG_BACKLIGHT_CLASS_DEVICE are now also limited to backlight.c . No functional changes intended. This has been tested on a Packard Bell Dot SC (Intel Atom N2600, cedarview) and a Sony Vaio vpc-x11s1e (Intel N540, poulsbo) laptop. Changes in v2: - Fix unused variable warnings when CONFIG_BACKLIGHT is not selected by marking the 2 variables as __maybe_unused.

2022-09-17drm/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.
