      platform/chrome: chromeos_laptop - instantiate Atmel at primary address · 96cba9b0
      由 Dmitry Torokhov 提交于 
      The new Atmel MXT driver expects i2c client's address contain the
primary (main address) of the chip, and calculates the expected
bootloader address form the primary address. Unfortunately chrome_laptop
does probe the devices and if touchpad (or touchscreen, or both) comes
up in bootloader mode the i2c device gets instantiated with the
bootloader address which confuses the driver.

To work around this issue let's probe the primary address first. If the
device is not detected at the primary address we'll probe alternative
addresses as "dummy" devices. If any of them are found, destroy the
dummy client and instantiate client with proper name at primary address
still.

      toshiba_acpi: Do not register vendor backlight when acpi_video bl is available · 358d6a2c
      由 Hans de Goede 提交于 
      commit a39f46df ("toshiba_acpi: Fix regression caused by backlight extra
check code") causes the backlight to no longer work on the Toshiba Z30,
reverting that commit fixes this but restores the original issue fixed
by that commit.

Looking at the toshiba_acpi backlight code for a fix for this I noticed that
the toshiba code is the only code under platform/x86 which unconditionally
registers a vendor acpi backlight interface, without checking for acpi_video
backlight support first.

This commit adds the necessary checks bringing toshiba_acpi in line with the
other drivers, and fixing the Z30 regression without needing to revert the
commit causing it.

Chances are that there will be some Toshiba models which have a non working
acpi-video implementation while the toshiba vendor backlight interface does
work, this commit adds an empty dmi_id table where such systems can be added,
this is identical to how other drivers handle such systems.

      ACPI / scan: Add a scan handler for PRP0001 · 7d284352
      由 Rafael J. Wysocki 提交于 
      If the special PRP0001 device ID is present in the given device's list
of ACPI/PNP IDs and the device has a valid "compatible" property in
the _DSD, it should be enumerated using the default mechanism,
unless some scan handlers match the IDs preceding PRP0001 in the
device's list of ACPI/PNP IDs.  In addition to that, no scan handlers
matching the IDs following PRP0001 in that list should be attached
to the device.

To make that happen, define a scan handler that will match PRP0001
and trigger the default enumeration for the matching devices if the
"compatible" property is present for them.

Since that requires the check for platform_id and device->handler
to be removed from acpi_default_enumeration(), move the fallback
invocation of acpi_default_enumeration() to acpi_bus_attach()
(after it's checked if there's a matching ACPI driver for the
device), which is a better place to call it, and do the platform_id
check in there too (device->handler is guaranteed to be unset at
the point where the function is looking for a matching ACPI driver).
