fix-lis302dl-resume-and-init-reload-boot-coefficients.patch
Reported-by: John Lee <john_lee@openmoko.com>
We don't reset the devices either at init or resume, where init
means use the BOOT bit to reload device calibration coefficients
from internal EEPROM. John Lee saw brain-damaged behaviour after
resume and sometimes after boot (since it may not have lost power
to force a BOOT itself that makes sense).
This patch
- adds a diagnostic dump feature down /sys
- forces BOOT action on init and resume, and waits for
completion
- makes sure XYZ capture is enabled on resume
- adds some constants in the .h and removes some magic numbers
in the code by using them
