2022-05-06drivers/intel/usb4: Add Type-C port device attachment checkJohn
When fwupd Retimer firmware update is enabled, it needs to differentiate the Type-C port NDA and USB/DP/TBT/USB4 DA scenarios. This change adds support to query devices attachment. If DA, it deasserts the Retimer power and promptly returns -1 accordingly without impacting the flow of Retimer firmware update under NDA. Additionally, this patch deasserts the Retimer power during error conditions. BUG=b:212235056, 224923449, 211790542 TEST=Validated Retimer firmware update under NDA and TBT3 docks enumeration on Type-C ports under DA.

2021-12-13drivers/intel/usb4/retimer: Add function to correct EC port mappingMAULIK V VAGHELA
Currently coreboot interprets TCSS port number as per physical port number while EC abstracts port number and provides indices as port number. For example, if TCSS port 1 and 3 are enabled on the board, coreboot will interpret port numbers as 0 and 2, but since only 2 ports are enabled in the system EC will assign port numbers as 0 and 1. This creates a port number mismatch while communicating between EC and coreboot. This patch addresses issue where SoC can implement function to map correct EC port as per port enabled in mainboard. BUG=b:207057940 BRANCH=None TEST=Check if code compiles successfully. Functionality will work once function is implemented in SoC code.

2021-07-12drivers/intel/usb4/retimer: Update code to assign correct port numberMaulik V Vaghela
Since TBT controller can have maximum 2 ports per controller, our code will loop over DFP structure twice and determine port number. Retimer driver used to assign port number as below: 1. Check if power GPIO is assigned for particular DFP entry or not 2. If entry is there, assign loop count as port number Since loop count is 2, retimer will never assign port number = 2 even if it's present. In case of more than 1 controller, port number assigned will still be 0 or 1 even though actual port index might be 2 or 3. This will create an issue where even if you do transaction on device on controller 2 (port index 2 or 3), EC will route it on port 0 or 1 due to incorrect port index. Update the driver flow as per below to handle this scenario: 1. Check if power GPIO is assigned for particular DFP entry or not 2. Get USB port number from config since it's stored in usb port information under devicetree 3. Pass the port number to ACPI SSDT and EC code Above changes will ensure that we're assigning correct port number as per calculation and EC will use correct port index. BUG=b:189476816 BRANCH=None TEST=Checked that retimer firmware update works on both ports and update happens on correct port index.

2021-03-22acpi/acpigen.h: Add more intuitive AML package closing functionsJakub Czapiga
Until now every AML package had to be closed using acpigen_pop_len(). This commit introduces set of package closing functions corresponding with their opening function names. For example acpigen_write_if() opens if-statement package, acpigen_write_if_end() closes it. Now acpigen_write_else() closes previously opened acpigen_write_if(), so acpigen_pop_len() is not required before it.
