lis3lv02d: add axes knowledge of HP Pavilion dv5 models

2009-02-18T23:37:54+00:00

Add support for HP Pavilion dv5.

Since Intel-based models have an inverted x axis, while AMD-based models
have an inverted y axis, we introduce a new macro that special-cases axis
orientation based on two DMI entries: HP dv5 axis configuration is then
based on both the PRODUCT and BOARD name.

lis3lv02d: support both one- and two-byte sensors

2009-02-18T23:37:54+00:00

Sensors responding with 0x3B to WHO_AM_I only have one data register per
direction, thus returning a signed byte from the position which is
occupied by the MSB in sensors responding with 0x3A.

Since multiple sensors share the reply to WHO_AM_I, we rename the defines
to better indicate what they identify (family of single and double
precision sensors).

We support both kind of sensors by checking for the sensor type on init
and defining appropriate data-access routines and sensor limits (for the
joystick) depending on what we find.

hp accelerometer: add freefall detection

2009-02-18T23:37:54+00:00

This adds freefall handling to hp_accel driver.  According to HP, it
should just work, without us having to set the chip up by hand.

hpfall.c is example .c program that parks the disk when accelerometer
detects free fall.  It should work; for now, it uses fixed 20seconds
protection period.

hp_accel: do not call ACPI from invalid context

2009-01-16T00:39:41+00:00

The LED on HP notebooks is connected through ACPI.  That unfortunately
means that it needs to be delayed by using schedule_work() to avoid
calling the ACPI interpreter from an invalid context.

lis3lv02d: merge with leds hp disk

2009-01-16T00:39:40+00:00

Move the second part of the HP laptop disk protection functionality (a red
led) to the same driver.  From a purely Linux developer's point of view,
the led and the accelerometer have nothing related.  However, they
correspond to the same ACPI functionality, and so will always be used
together, moreover as they share the same ACPI PNP alias, there is no
other simple to allow to have same loaded at the same time if they are not
in the same module.  Also make it requires the led class to compile and
update the Kconfig text.

LIS3LV02D: separate the core from HP ACPI API

2009-01-10T00:54:42+00:00

The sensor can be accessed via various buses.  In particular, SPI, I²C
and, on HP laptops, via a specific ACPI API (the only one currently
supported).  Separate this latest platform from the core of the sensor
driver to allow support for the other bus type.  The second, and more
direct goal is actually to be able to merge this part with the
hp-disk-leds driver, which has the same ACPI PNP number.
