From 56fcfb5b4f00830d0c1bf2230e1104045d795c82 Mon Sep 17 00:00:00 2001 From: Tim Wawrzynczak Date: Tue, 10 Nov 2020 13:39:37 -0700 Subject: soc/intel/common: Adapt XHCI elog driver for reuse 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 Reviewed-on: https://review.coreboot.org/c/coreboot/+/47411 Reviewed-by: Furquan Shaikh Tested-by: build bot (Jenkins) --- src/soc/intel/cannonlake/xhci.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/soc/intel/cannonlake/xhci.c') diff --git a/src/soc/intel/cannonlake/xhci.c b/src/soc/intel/cannonlake/xhci.c index 46cc120a06..0fb093682d 100644 --- a/src/soc/intel/cannonlake/xhci.c +++ b/src/soc/intel/cannonlake/xhci.c @@ -1,5 +1,6 @@ /* SPDX-License-Identifier: GPL-2.0-only */ +#include #include #define XHCI_USB2_PORT_STATUS_REG 0x480 @@ -14,7 +15,7 @@ static const struct xhci_usb_info usb_info = { .num_usb3_ports = XHCI_USB3_PORT_NUM, }; -const struct xhci_usb_info *soc_get_xhci_usb_info(void) +const struct xhci_usb_info *soc_get_xhci_usb_info(pci_devfn_t xhci_dev) { return &usb_info; } -- cgit v1.2.3
