mfd: Adopt mfd_data in 88pm860x backlight

2011-03-23T09:42:05+00:00

Copy 88pm860x platform data into different mfd_data structure for
backlight driver. So move the identification of device node from
backlight driver to mfd driver.

pwm_backlight: add check_fb() hook

2011-03-23T00:44:00+00:00

In systems with multiple framebuffer devices, one of the devices might be
blanked while another is unblanked.  In order for the backlight blanking
logic to know whether to turn off the backlight for a particular
framebuffer's blanking notification, it needs to be able to check if a
given framebuffer device corresponds to the backlight.

This plumbs the check_fb hook from core backlight through the
pwm_backlight helper to allow platform code to plug in a check_fb hook.

drivers/video/backlight/jornada720_*.c: make needlessly global symbols static

2011-03-23T00:44:00+00:00

The following symbols are needlessly defined global: jornada_bl_init,
jornada_bl_exit, jornada_lcd_init, jornada_lcd_exit.

Make them static.

backlight: apple_bl depends on ACPI

2011-03-23T00:44:00+00:00

apple_bl uses ACPI interfaces (data & code), so it should depend on ACPI.

mbp_nvidia_bl: rename to apple_bl

2011-03-23T00:44:00+00:00

It works on hardware other than Macbook Pros, and it works on GPUs other
than Nvidia.  It should even work on iMacs, so change the name to match
reality more precisely and include an alias so existing users don't get
confused.

mbp_nvidia_bl: check that the backlight control functions

2011-03-23T00:44:00+00:00

The SMI-based backlight control functionality may fail to work if the
system is running under EFI rather than BIOS.  Check that the hardware
responds as expected, and exit if it doesn't.

mbp_nvidia_bl: remove DMI dependency

2011-03-23T00:44:00+00:00

This driver only has to deal with two different classes of hardware, but
right now it needs new DMI entries for every new machine. It turns out
that there's an ACPI device that uniquely identifies Apples with backlights,
so this patch reworks the driver into an ACPI one, identifies the hardware
by checking the PCI vendor of the root bridge and strips out all the DMI
code. It also changes the config text to clarify that it works on devices
other than Macbook Pros and GPUs other than nvidia.

backlight: add backlight type

2011-03-23T00:43:59+00:00

There may be multiple ways of controlling the backlight on a given
machine.  Allow drivers to expose the type of interface they are
providing, making it possible for userspace to make appropriate policy
decisions.
