The Lenovo H8 battery interface uses a paged EC memory area. Some Thinkpads (in particular the S230U) use a different EC controller (ENE KB9012) with mostly compatible firmware, which requires an explicit delay between writing the page register and reading the page data.

2017-03-06ec/lenovo/h8: Use older syntax for bit shiftPaul Menzel
Currently, when using `iasl` 20140926-32 [Oct 1 2014] from Debian 8 (Jessie/stable), the build of the Lenovo X60 fails due to syntax errors. ASL 2.0 supports `<<`. For consistency, right now, coreboot still uses the old syntax. So use `ShiftLeft` instead, which also fixes the build issue with older ASL compilers.

thinkpad_acpi expects a SSMS method to turn on/off the mute LED and a MMTS method to turn on/off the microphone mute LED. With these methods implemented the driver can correctly sync the LEDs with the corresponding statuses. There seems to be two different bits to mute the audio in the Lenovo H8 EC: * AMUT, used internally (for example to disable the audio before entering S3). * ALMT, controllable by the OS, which also toggles the mute LED (if present).

2017-02-24ec/lenovo/h8: Guard against EC bugs in the battery status logic.Tobias Diedrich
On my Thinkpad with an H8-compatible ENE KB9012 EC (GDHT92WW 1.52), when the battery is nearly full and we switch from battery to AC by plugging in the cable, the current rate will not drop to 0 immediately, but the discharging state is cleared immediately. This leads to the code trying to process an invalid rate value >0x8000, leading to a displayed rate of >1000W. This patch changes the logic to deal with these corner cases.

This fixes an issue on systems where the S3 state in the pm1 control registers are not cleared when vboot determines recovery mode is required on an S3 resume. The EC code will reboot the system knowing that the EC was in RW. However, on subsequent entry into romstage the S3 path will be taken and fails to recover cbmem -- forcing another reboot. To work around that, signal to the platform a reboot is happening and let the platform perform the necessary fix ups to the register state.

USB AO is the internal name for the dedicated charging port on ThinkPads when in S3 or lower. AOEN (bit 0) is internal name for enabling this feature while AOCF (bits 2 and 3) is the configuration field. According to Peter Stuge, AOCF can be configured in this way: 00 => AC S3 S4 S4 USB on, battery S3 USB on, battery S4 S5 off 11 => AC S3 S4 S4 USB on, battery S3 S4 S5 USB off 10, 01 => equivalent to 00 This commit also adds a new configuration field in the CMOS of the X220 and the X201 to activate this feature. It probably can be also added to all the ThinkPads that support this functionality. With this functionality USB devices are able to negotiate full power from the dedicated port (usually the yellow one) even in S3. Tested on a X201 and X220 with an Android smartphone: with this feature enabled it shows "Charging" when connected during S3, without it it shows "Charging slowly" (or it doesn't charge at all on the X201). For some reasons the "AC only" mode doesn't work, so it has been disabled.

2016-10-02Kconfig: Update default hex values to start with 0xMartin Roth
Kconfig hex values don't need to be in quotes, and should start with '0x'. If the default value isn't set this way, Kconfig will add the 0x to the start, and the entry can be added unnecessarily to the defconfig since it's "different" than what was set by the default. A check for this has been added to the Kconfig lint tool.

2016-08-04chromeec: Chrome EC firmware source selection for EC and PD firmwaresPaul Kocialkowski
In some cases, we don't want the Chrome EC firmwares (both EC and PD) built directly by the coreboot build system or included in images at all. This is already supported with EC_EXTERNAL_FIRMWARE but it does implement a binary (build and include) or (neither build nor include) policy. Some cases require the ability to separately control whether the EC and PD firmwares should be built and included by the coreboot build system, only included from externally-built images or not included at all. This introduces config changes implementing that behaviour, renaming options to make it clear that they are specific to the Chrome EC.
