* console: compile some channels in conditionallyVadim Bendebury2015-07-251-0/+6
| | | | | | | | | | | | | | | | As new features come along the console channel space limited at 32 becomes very tight. But not all features are present all the time. Let's make some of the channels compile time configurable. This makes for uglier code but allows to support more channels.

* cr50: Use distinct configuration option for SPI Slave supportVadim Bendebury2015-07-251-0/+1
| | | | | | | | | | | | | | | | | | | | SPI slave and master interfaces require very different code to support, they should have separate configuration options. Host command code printouts should use their own console channel. Using SPS to designate SPI Slave interface is not universally acceptable, a bug has been opened to discuss the alternatives and clean up the code.

* rambi: glimmer: Disable key scanning in suspend when lid is openAlec Berg2014-03-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Added ability to disable the keyboard to wake from suspend when the lid is outside a certain angle range. This has been added to glimmer by defining CONFIG_LID_ANGLE_KEY_SCAN in its board.h.

BUG=none BRANCH=rambi TEST=Tested on a glimmer: In S3, verified that when the lid is open past ~180 deg, the keyboard does not wake the machine. Also verified that if you align hinge with gravity, the keyboard enabled/disabled status remains the same (since we can't actually trust the lid angle value).

* rambi: Add motion sense task to track motionAlec Berg2014-02-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added motion sense task to Clapper and Glimmer. This task samples the accelerometers and calculate a lid angle. Note that as the machine is rotated towards the hinge angle aligning with gravity, the lid calculation becomes less trustworthy. Added a math_util file to hold various mathematical functions useful for calculating lid angle that may be helpful in other places. For each board with accelerometers we need to define some orientation specific data in board.c. There is a calibration procedure through the EC console that can be enabled by defining CONFIG_ACCEL_CALIBRATE. The calibration procedure can help determine the orientation data required. For debugging purposes there is a console command to regularly print to the EC console the accelerometer data and derived lid angle. The console command can be enabled by defining CONFIG_CMD_LID_ANGLE. BUG=none Original-BUG=chrome-os-partner:24703 BRANCH=rambi TEST=Ran the calibration procedure on a Glimmer unit, and then rotated the machine in space.

* lm4: Add a low power idle task.stabilize-4825.BAlec Berg2013-10-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First implementation of a low power idle task for the LM4 chip. The low power mode is selected by defining CONFIG_LOW_POWER_IDLE in a board.h file. This commit turns it on for Peppy, Slippy, and Falco only because those are the only boards tested. When using the low power idle task, the chip goes in to deep sleep when it can. Deep sleep disables clocks to most peripherals and puts the onboard flash and RAM into a low power mode. The chip is woken out of deep sleep using the RTC in the hibernate module. Increased the idle task stack size to handle more involved idle task. In board.c, the array of GPIO info can be used to select which GPIO points can wake up the EC from deep sleep. Currenlty selected are the power button, lid open, AC present, PCH_SLP_S3, and PCH_SLP_S5. Additionally the port with the KB scan row GPIO point is also enabled to wake up the EC from deep sleep. Signed-off-by: Alec Berg <alecaberg@chromium.org> BUG=None BRANCH=none TEST=Passes all unit tests. Runs on slippy, peppy, and falco with no noticeable side affects. Verified that the power consumed by the EC is lower when in S3, S5 and G3 by scoping the sense resistor powering the chip.
