2024-02-13drivers/gfx/generic: Add display type fieldMatt DeVillier
Add an enum for the Display Type, which if set, can be used to generate the Device ID value dynamically when the addr field is not set. This will allow devicetree entries to specify the display type instead of a hex value for the address which requires referencing the ACPI spec to decode. For an internal panel connected to the first port on the graphics chip, currently an addr value of 0x80010400 is specified. Replacing the 'addr' field with the 'type' field and setting it to 'panel' will generate the same DID value.

2023-05-08drivers/gfx/generic: Add _PLD support to GFX deviceWon Chung
Add _PLD support to GFX device so that each display output can store its physical location of connection point. This is to be used primarily for describing DP on USB-C ports in the future patches. The upstream Linux kernel now has a feature to compare _PLD of Type C connectors and DP connectors to link them together. https://cgit.freedesktop.org/drm/drm-misc/commit/?id=c5c51b2420625faa1f0e363f21dba1de53806ff7 This feature allows us to tell which display output is used by which USB-C port. So, for the future boards, we want to add _PLD for each DP connector matching with the corresponding USB-C port.

2020-05-02acpi: Move ACPI table support out of arch/x86 (3/5)Furquan Shaikh
This change moves all ACPI table support in coreboot currently living under arch/x86 into common code to make it architecture independent. ACPI table generation is not really tied to any architecture and hence it makes sense to move this to its own directory. In order to make it easier to review, this change is being split into multiple CLs. This is change 3/5 which basically is generated by running the following command: $ git grep -iIl "arch/acpi" | xargs sed -i 's/arch\/acpi/acpi\/acpi/g' BUG=b:155428745 Change-Id: I16b1c45d954d6440fb9db1d3710063a47b582eae Signed-off-by: Furquan Shaikh <furquan@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/40938 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: HAOUAS Elyes <ehaouas@noos.fr>

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.

2020-02-24gfx: Move drivers/generic/gfx to drivers/gfx/genericFurquan Shaikh
This change creates gfx directory under drivers/ so that all drivers handling gfx devices can be located in the same place. In follow-up CLs, we will be adding another driver that handles gfx devices. This change also updates the names used within the driver from *generic_gfx* to *gfx_generic*. In addition to that, mainboard drallion using this driver is updated to match the correct path and Kconfig name. TEST=Verified that drallion still builds.
