2018-05-03ec/google/chromeec: Update Tablet event callMartin Roth
The tablet event handler method TPET is defined as an extern, then defined again in skylake, the only platform that supports it. In newer versions of IASL, this generates an error, as the method is defined in two places. Remove the extern and the CondRefOf check. That's not needed if we only set the EC_ENABLE_TABLET_EVENT define on platforms that have a TPET handler.

2018-05-01chromeec platforms: Update ACPI thermal event handler callMartin Roth
Currently the thermal event handler method TEVT is defined as an extern, then defined again in platforms with thermal event handling. In newer versions of IASL, this generates an error, as the method is defined in two places. Simply removing the extern causes the call to it to fail on platforms where it isn't actually defined, so add a preprocessor define where it's implemented, and only call the method on those platforms.

2018-04-30cros-ec: Avoid infinitely looping in google_chromeec_pd_get_amodeDaisuke Nojiri
Currently, google_chromeec_pd_get_amode infinitely loops if a TCPC port is connected to a device with alternate mode(s) and the call is made for the mode with the index higher than 0 (e.g. Zinger). Cros EC manages alternative modes entered in an array (amode[]). The command is designed to accept a query for an particular index and a particular SVID. Zinger has a 'Google' mode. It's stored in amode[0]. When AP queries first time for DisplayPort with index=0, EC says 'no' as expected. AP sends the next query with index=1 but EC_CMD_PROTO_VERSION (0x00) is sent instead because cmd_code is cleared by google_chromeec_command. res.svid is supposed to be 0 when EC hits the last index + 1 but res.svid is set to 2 by the EC_CMD_PROTO_VERSION handler because EC_PROTO_VERSION is currently 2. So, the call succeeds and AP goes to the next index and this repeats forever. Any USB-C device with non-DisplayPort alternate mode can cause this hang unless HDMI port is used. This patch resets all the fields of chromeec_command in each iteration in case google_chromeec_command changes them. BUG=b:78630899 BRANCH=none TEST=Verify Fizz boots without monitors on Zinger. Verify the svid enumeration happens as expected.

2018-03-06mainboard/google/fizz: Check HDMI HPD and DisplayPort HPDDaisuke Nojiri
Some type-c monitors do not immediately assert HPD. If we continue to boot without HPD asserted, Depthcharge fails to show pictures on a monitor even if HPD is asserted later. Also, if an HDMI monitor is connected, no wait is needed. If only an HDMI monitor is connected, currently the API always loops until the stopwatch expires. This patch will make the AP skip DisplayPort wait loop if it detects an HDMI monitor.

But newer version of BIOS/OS is expected to use UHEPI command (EC_CMD_PROGRAM_HOST_EVENT) The UHEPI also enables the active and lazy wake masks. Active wake mask is the mask that is programmed in the LPC driver (i.e. the mask that is actively used by LPC driver for waking the host during suspended state). It is same as the current wake mask that is set by the smihandler on host just before entering sleep state S3/S5. On the other hand, lazy wake masks are per-sleep masks (S0ix, S3, S5) so that they can be used by EC to set the active wake mask depending upon the type of sleep that the host has entered. This allows the host BIOS to perform one-time programming of the wake masks for each supported sleep type and then EC can take care of appropriately setting the active mask when host enters a particular sleep state.

2017-11-22chromeec: Change the API for hostevent/wake masks to handle 64-bitFurquan Shaikh
ChromeEC is getting ready to bump up the hostevents and wake masks to 64-bits. The current commands to program hostevents/wake masks will still operate on 32-bits only. A new EC host command will be added to handle 64-bit hostevents/wake masks. In order to prevent individual callers in coreboot from worrying about 32-bit/64-bit, the same API provided by google/chromeec will be updated to accept 64-bit parameters and return 64-bit values. Internally, host command handlers will take care of masking these parameters/return values to appropriate 32-bit/64-bit values.

2017-10-18google/chromeec: Drain all MKBP events while clearing host eventsFurquan Shaikh
EC maintains a FIFO of all MKBP events and sets host event whenever a new entry is added to the FIFO. Clearing only the host event for MKBP creates an inconsistent state where there are pending MKBP events in the FIFO but host event for MKBP is cleared. In order to maintain a consistent view, host should clear all MKBP events in the FIFO if host event is being cleared. This change drains out all the MKBP events in the FIFO when clear_pending_events is called. TEST=Verified by adding debug logs in EC to verify that all the MKBP events that occur before clear_pending_events is called get cleared from the FIFO.

2017-10-04chromeec: Remove checks for EC in RODaisuke Nojiri
This patch removes checks that ensure EC to be in RO for recovery boot. We do not need these checks because when recovery is requested automatically (as opposed to manually), we show 'broken' screen where users can only reboot the device or request recovery manually. If recovery is requested, Depthcharge will check whether EC is in RO or not and recovery switch was pressed or not. If it's a legitimate manual recovery, EC should be in RO. Thus, we can trust the recovery button state it reports. This patch removes all calls to google_chromeec_check_ec_image, which is called to avoid duplicate memory training when recovery is requested but EC is in RW.
