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>
2020-04-28device: Constify struct device * parameter to acpi_fill_ssdt()Furquan Shaikh
.acpi_fill_ssdt() does not need to modify the device structure. This change makes the struct device * parameter to acpi_fill_ssdt() as const.

2020-04-10Replace DEVICE_NOOP with noop_(set|read)_resourcesNico Huber
`.read_resources` and `.set_resources` are the only two device operations that are considered mandatory. Other function pointers can be left NULL. Having dedicated no-op implementations for the two mandatory fields should stop the leaking of no-op pointers to other fields.

2020-04-10Drop unnecessary DEVICE_NOOP entriesNico Huber
Providing an explicit no-op function pointer is only necessary for `.read_resources` and `.set_resources`. All other device-operation pointers are optional and can be NULL.

2020-04-02Trim `.acpi_fill_ssdt_generator` and `.acpi_inject_dsdt_generator`Nico Huber
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.

2019-10-22AUTHORS: Move src/drivers/[a*-i*] copyrights into AUTHORS fileMartin Roth
As discussed on the mailing list and voted upon, the coreboot project is going to move the majority of copyrights out of the headers and into an AUTHORS file. This will happen a bit at a time, as we'll be unifying license headers at the same time. Updated Authors file is in a separate commit.

2019-02-08drivers/gpio_keys: Remove redundant is_wakeup_source flagKarthikeyan Ramasubramanian
"is_wakeup_source" flag is used to indicate if the concerned device can trigger a wakeup. This flag is redundant with the "wake" GPE event definition. So remove the redundant flag and use the "wake" GPE event to mark the wakeup source. BUG=None BRANCH=None TEST=Boot to ChromeOS. Ensure that the device is marked as wakeup-source in SSDT if wake GPE is configured. Ensure that the system can suspend and the device acts as a wakeup source Change-Id: I99237323639df1cb72e3a81bcfed869900a2eefa Signed-off-by: Karthikeyan Ramasubramanian <kramasub@google.com> Reviewed-on: https://review.coreboot.org/c/31258 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
