* tegra: Remove 'power' console commandVic Yang2014-09-241-59/+0
| | | | | | | | | | | | | | | | | The 'power' console command is entirely redundant: - 'power on' can be replaced by 'powerbtn'. - 'power off' can be replaced by 'apshutdown'. - 'power' can be replaced by 'powerinfo'. Let's remove this command to save flash space. BUG=chrome-os-partner:32203 TEST=Build Ryu.

* Veyron: Reset the PMIC properly at power onAlexandru M Stan2014-09-041-35/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a way to brick the PMIC by programming its registers with a bad configuration, this could prevent the AP from powering up properly (thus not being able to unbrick it). The PMIC retains register state through S5 (presumably due to RTC business) and they do not get reset at bootup unless the OTP reset is asserted. The OTP reset actually has to be asserted in a special(rather long as well) sequence. A bug was discovered while making this change(crosbug.com/p/31635): usleep does not work for long delays. Since I needed at least 300ms on one of the delays I used a workaround with a loop. I also cleaned up some old tegra stuff and renamed things to be more semantic. BUG=None BRANCH=None TEST=From the AP set a PMIC register from the default value of 0x7d to 0xfd: user@ap~$ modprobe i2c-dev user@ap~$ i2cget -f -y 0 0x1b 0x24 Check what the default state is, mine was 0x7d user@ap~$ i2cset -f -y 0 0x1b 0x24 0xfd #or change 0xfd to something!=default Cold reboot the dut("apreset" or "power on\npower off" will work) then check if the PMIC registers got reset: user@ap~$ modprobe i2c-dev user@ap~$ i2cget -f -y 0 0x1b 0x24 0x7d(or whatever your default state was) #good 0xfd #bad, did not reset properly Using "user@ap~$ i2cset -f -y 0 0x1b 0x24 0x00" instead will prove the bricking of the PMIC/AP.

* baytrail: Workaround for stuck boot processRandall Spangler2014-04-301-0/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases, the system will boot to S0 from the point of view of the EC, but PLTRST# will never deassert. Work around this by waiting 50 ms for PLTRST# to deassert. If it doesn't, force the chipset all the way down by deasserting RSMRST#, then pulse the power button to turn it back on. Also add a powerfail debug command to simulate this failure event, so that the recovery process can be tested. Add API to the LPC module to get the state of PLTRST#, and to the power button state machine to force it released when we shut down the chipset and and force another power button pulse as we reset the chipset. BUG=chrome-os-partner:28422 BRANCH=baytrail TEST=1. Boot system. Should boot normally. Shut system down. 2. powerfail 3. Boot system. On the EC console, should see the system come up, go back down through G3S5, then come back up. From the user's point of view, it just boots. 1. Boot system. Should boot normally.

When all disable sources are off, scanning is enabled, otherwise scanning is disabled. This fixes a recently introduced bug in which enabling/disabling keyboard scanning due to lid angle in S3 was interfering with enabling/disabling keyboard scanning due to power button.
