XO 1.5 EC dev changelog

1.5 EC development change log

Ver: 1.9.5

Fixes:

Catch soft off. Soft off is dictated by SUSC and MAIN_ON (SUSB) when the signals go into a specific state it means that the host has turned itself off and the EC should shut down the voltage regulators.
Fix the polarity of the SUSC high low reporting. It was inverted.
Optimize the way the SCI timing reporting was happening the numbers reported by tMO now match the timestamps happening from MO L and MO H.

Features:

Disable sequence warnings fro srec_cat when building the .bin image
Update the make dev rule so that it copies the test code to 'ec_test.img' in the EC firmware dir.
Remove code that deals with a register we don't have. Leftover from another code base.
Compile option to disable timestamp printing. (if you need diagnostic stuff that has to go really fast)
Rename all the assert/deassert to enable/disable. This makes it so you can search for specific IO ops. Searching for assert_<bla> would also get you deassert_<BLA>.

Ver: 1.9.4

Fixes:

Features:

General purpose EC timer host wakeups. EC cmd 0x36 takes a signed long value that is the number of ms to wait and then it will issue a SCI 0x01. Allows wakeups with around 8 - 12 ms resolution for about 26 days in the future. (ie 2^31 milliseconds).
Autowak is synced with MAIN_ON going low to help duplicate a resume crash.
LiFePO4 debug dumps can now enabled or disabled via OFW.

Ver: 1.9.3 (Unreleased)

Fixes:

Fix a typo bug that was turing off CC0 rather than CHG
Clear the 1 wire guage cache values for voltage and current when there is not a respose to a presence pulse.

Features:

Tweak the power up sequecing state machine to remove the PWR_GOOD state since it was unused.
Make the POWER_BUT_IN# strobe pulse the same width for both power up from off and for the strobe when power is on.
Add support for setting the value on the CHGCTL pin so we can test this feature.
Refactor keyboard and touchpad wakeups so that you can tell the difference between the 2 and don't wakeup on keyboard break codes.

Ver: 1.9.2

Fixes:

reorder the scancode generation table to match the new ordering from the rewritten GetMatrixKeys.
Modify the polarity of some signals so they don't create leakage in S5
Reduce the VR_ON to RSMRST# delay to approx 20ms as requested by Beckham Chen @ quanta.
Fix no low voltage host shut off bug.
Battery charge taper current tweak 100mA -> 150mA.

Features:

Known Issues:

Battery debugging output was left enabled if you connect up a battery you will get a dump of various variables every second.
