3608a2cd - backlight: apple_bl: Use acpi_video_get_backlight_type()

Tue, 07 Mar 2023 12:05:40 +0000

backlight: apple_bl: Use acpi_video_get_backlight_type()On some MacBooks both the apple_bl and the apple-gmux backlight driversmay be able to export a /sys/class/backlight device.To avoid having 2 backlight devices for one LCD panel until nowthe apple-gmux driver has been calling apple_bl_unregister() to movethe apple_bl backlight device out of the way when it loads.Similar problems exist on other x86 laptops and all backlight driverswhich may be used on x86 laptops have moved to usingacpi_video_get_backlight_type() to determine whether they should loador not.Switch apple_bl to this model too, so that it is consistent with allthe other x86 backlight drivers.Besides code-simplification and consistency this has 2 other benefits:1) It removes a race during boot where userspace will briefly see an apple_bl backlight and then have it disappear again, leading to e.g.: https://bbs.archlinux.org/viewtopic.php?id=2699202) This allows user to switch between the drivers by passing acpi_backlight=apple_gmux or acpi_backlight=vendor on the kernel commandline.Signed-off-by: Hans de Goede Reviewed-by: Daniel Thompson Acked-by: Lee Jones Link: https://lore.kernel.org/r/20230307120540.389920-1-hdegoede@redhat.com List of files: /linux-6.15/drivers/video/backlight/Kconfig

Fri, 26 Jun 2020 10:25:00 +0000

backlight: Delete the OT200 backlight driverThis driver has no in-kernel users. The device can only be populatedby board files since it does not support device tree nor ACPI,and nothing in the kernel creates a device named "ot200-backlight".This driver has been in the kernel since 2012. If it is used byout-of-tree code that code should have been upstreamed by now,it's been 8 years.It uses the idiomatic forked GPIO of the CS5535 which combinespin control and GPIO into its private custom interface, whichcauses me a headache because that is not how we do things thesedays: we creates separate pin control and GPIO drivers.Delete this unused driver.Cc: Christian Gmeiner Signed-off-by: Linus Walleij Reviewed-by: Daniel Thompson Signed-off-by: Lee Jones List of files: /linux-6.15/drivers/video/backlight/Kconfig
