Hi All,
The Lenovo Yoga Book (yb1-x9*) is a yoga 2-in-1 where the keyboard
half has a touch keyboard (with a backlit fixed key layout) to make
it extra thin and light. The keyboard half can also be switched to
an alternative wacom digitizer mode where it instead can be used
to draw on. The backlight + switching is handled by
the lenovo-yogabook driver.
There are both Windows and Android versions with different BIOS-es /
ACPI tables. This series extends the current Windows model only driver
to also support the Android model.
On the Android yb1-x90f/l models there is not ACPI method to control
the keyboard backlight brightness. Instead the second PWM controller
is exposed directly to the OS there.
This requires adding a pwm_lookup table and the lenovo-yogabook code
can (and typically is) build as a module. So the first patch in
this series exports pwm_add_table() and pwm_remove_table() for use
in modules.
I believe that it is easiest to just merge the entire series through
the drivers/platform/x86 tree. Thierry, may I have your ack for
patch 1/19 to merge it through the pdx86 tree ?
Changes in v2:
- Address Andy's review remarks
- Error-exit handling fixes in yogabook_pdev_probe() and
yogabook_module_init()
- Explicitly turn off keyboard backlight on suspend
Regards,
Hans
