2024-10-07soc/intel/adl to jsl: Explicitly include static.h for config_of_socNicholas Chin
As per commit 865173153760 ("sconfig: Move config_of_soc from device.h to static.h"), sources that require access to the devicetree should directly include static.h so that it can be removed from device.h, eliminating unnecessary dependencies on static.h for files that only need the types and function declarations in device.h.

2021-11-04soc/intel: Replace bad uses of `find_resource`Angel Pons
The `find_resource` function will never return null (will die instead). In cases where the existing code already accounts for null pointers, it is better to use `probe_resource` instead, which returns a null pointer instead of dying.

2021-07-26soc/intel/jasperlake: Set xHCI LFPS period sampling off timeBen Kao
Provide an option to set xHCI LFPS period sampling off time (SS_U3_LFPS_PRDC_SAMPLING_OFFTIME_CTRL in JSL EDS revision 2.0). If the option is set in the devicetree, the bits[7:4] in xHCI MMIO BAR + offset 0x80A4 (PMCTRL_REG) will be updated. The host will sample LFPS for U3 wake-up detection when suspended, but it doesn't sample LFPS at all time due to power management, the default xHCI LFPS period sampling off time is 9ms. If the xHCI LFPS period sampling off time is not 0ms, the host may miss the device-initiated U3 wake-up and causes some kind of race condition for U3 wake-up between the host and the device. BUG=b:187801363, b:191426542 TEST=build coreboot with xhci_lfps_sampling_offtime_ms and flash the image to the device.

2020-12-10soc/intel/common: Adapt XHCI elog driver for reuseTim Wawrzynczak
Currently this XHCI driver assumes the PCH XHCI controller, but the TCSS or North XHCI block has a similar enough PCI MMIO structure to make this code mostly reusable. 1) Rename everything to drop the `pch_` prefix 2) xhci_update_wake_event() now takes in a pci_devfn_t for the XHCI controller 3) soc_get_xhci_usb_info() also now takes a pci_devfn_t for the XHCI controller BUG=b:172279037 TEST=plug in USB keyboard while in S0, enter S0ix and verify entry via EC; type on keyboard, verify it wakes up, eventlog contains: 39 | 2020-12-10 09:40:21 | S0ix Enter 40 | 2020-12-10 09:40:42 | S0ix Exit 41 | 2020-12-10 09:40:42 | Wake Source | PME - XHCI (USB 2.0 port) | 1 42 | 2020-12-10 09:40:42 | Wake Source | GPE # | 109 which verifies it still functions for the PCH XHCI controller Change-Id: I9f28354e031e3eda587f4faf8ef7595dce8b33ea Signed-off-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/47411 Reviewed-by: Furquan Shaikh <furquan@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
