These two identifiers were always very confusing. We're not filling and injecting generators. We are filling SSDTs and injecting into the DSDT. So drop the `_generator` suffix. Hopefully, this also makes ACPI look a little less scary.

2020-03-20ec/google/chromeec: don't put empty block in SSDTMatt DeVillier
Check that there are actually USB-PD ports for which to add data to SSDT, before actually generating SSDT data. This prevents an empty scope from being generated on devices without any USB-PD ports, which was breaking parsing/decompilation on some older platforms (eg, Braswell). Test: build/boot google/edgar, verify SSDT table able to be parsed via iasl after dumping.

2020-03-17src (minus soc and mainboard): Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2020-03-06ec/google/chromeec: Fix dev ops for chromeecFurquan Shaikh
CB:38541 ("ec/google/chromeec: Add SSDT generator for ChromeOS EC") added a new device_operations structure for chromeec for handling ACPI SSDT generation. However, this resulted in the original device_operations which handled lpc read resources to be skipped. This change fixes the above regression by combining the device operations for reading resources and ACPI SSDT generation into a single structure and retains the old logic for enabling of pnp devices.

2020-02-28ec/google/chromeec: Introduce SKU_ID helpersEdward O'Callaghan
The following introduces helpers that, by default, accommodate a larger SKU id space. The following is the rational for that: Allow INT32_MAX SKU id encodings beyond UINT8_MAX. This allows for the SKU id to accommodate up to 4 bytes however we reserve the highest bit for SKU_UNKNOWN to be encoded. However, the legacy UINT8_MAX encoding is supported by leveraging the Kconfig by overriding it with the legacy max of 0xff. Follow ups migrate boards to this common framework. V.2: Fixup array size && drop sku_id SKU_UNKNOWN check and pass whatever is set to userspace as firmware doesn't care about the value. V.3: Use SPDX-License header.

Upcoming patches for the Linux kernel (5.6 ?) would like to consume information about the USB PD ports that are attached to the device. This information is obtained from the CrOS EC and exposed in the SSDT ACPI table. Also, the device enable for this PCI device is moved from ec_lpc.c to a new file, ec_chip.c, where EC-related ACPI methods can live.

After ChromiumOS CL:1293132 and CL:1295890, Chrome EC can store the flag telling if the last reboot was triggered by AP watchdog for some boards (e.g., Kukui). This CL adds a new function google_chromeec_get_ap_watchdog_flag(), which reads the AP watchdog flag from Chrome EC, and updates the tables of reset causes and reset flags. A new Kconfig option CHROMEOS_USE_EC_WATCHDOG_FLAG is added for elog_handle_watchdog_tombstone() to determine if watchdog reset was triggered by the AP watchdog flag from EC instead of the tombstone in AP.

2018-11-12ec/google/chromeec: Configure EC_SYNC_IRQ as level triggeredFurquan Shaikh
EC_SYNC_IRQ from EC to host is level-triggered in practice and configuring it as edge-triggered on the host results in host missing events if there are multiple events queued on the EC side. This is because Linux kernel driver reads one event per irq and the EC does not de-assert the interrupt line until all events are drained out. This results in event queue being filled up completely on the EC and the host failing to see any of those events. This change configures EC_SYNC_IRQ as level triggered to allow the host to read events from the the EC as long as the line is asserted.

2018-11-06chromeec: Disable battery remaining capacity workaroundDaisuke Nojiri
If remaining charge is more than x% of the full capacity, the remaining charge is raised to the full capacity before it's reported to the rest of the system. Some batteries don't update full capacity timely or don't update it at all. On such systems, compensation is required to guarantee the remaining charge will be equal to the full capacity eventually. On some systems, Rohm charger generates audio noise when the battery is fully charged and AC is plugged. A workaround is to do charge- discharge cycles between 93 and 100%. On such systems, compensation was also applied to mask this cycle from users. This used to be done in ACPI, thus, all software components except EC was able to see the compensated charge. This patch is part of the effort of moving the logic to EC. With this and the EC changes, EC can see what the rest of the system sees, thus, can control LEDs synchronously (to the display percentage). Another rationale of this move is EC can perform more granular and precise compensation than ACPI since it has more knowledge about the battery and the charger.

Some boards are adding a second pin used for synchronization between the EC and AP. This is a direct connection between the EC and the SOC that is intended to provide a lower latency interrupt signal for sensors on the EC. Currently the runtime EC interrupts assert an SCI before eventually resulting in a Notify() on the MKBP device that the sensor driver users. These extra layers add processing time and require additional EC communication to determine the event source. This interface was tested on a reworked Nocturne board with modified EC and a modified kernel driver to ensure that the interrupt asserts as expected and can be used by the kernel driver.

On some detachables, the mere presence of attached base is not enough to determine whether the device is in tablet mode or not, so we introducing a new "switch" in EC, separate from "Tablet Mode" switch, to signal whether the base is attached or not. We also want the driver to be separate from cros_ec_keyb, so we create a new ACPI device, C(hrome)B(ase)A(ttached)S(witch), with HID GOOG000B, and guard it with EC_ENABLE_CBAS_DEVICE.

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.
