commit 86f0c3ec13aa6d583a586f343329d15faf22bd75 Author: Adrian Chadd <[email protected]> AuthorDate: 2021-12-28 02:21:36 +0000 Commit: Adrian Chadd <[email protected]> CommitDate: 2021-12-28 02:21:36 +0000 ipq4018_usb_phy: add USB 2.0 and 3.0 PHY support This adds the USB 2.0 and 3.0 PHY support for the IPQ4018/IPQ4019. All it really needs to do is gate the relevant clocks on/off in the right order with the right delays. --- sys/arm/conf/std.qca | 4 + sys/arm/qualcomm/ipq4018_usb_hs_phy.c | 236 ++++++++++++++++++++++++++++++++++ sys/arm/qualcomm/ipq4018_usb_ss_phy.c | 218 +++++++++++++++++++++++++++++++ sys/arm/qualcomm/std.ipq4018 | 3 + 4 files changed, 461 insertions(+) diff --git a/sys/arm/conf/std.qca b/sys/arm/conf/std.qca index bb884531508b..c835b3c94616 100644 --- a/sys/arm/conf/std.qca +++ b/sys/arm/conf/std.qca @@ -61,3 +61,7 @@ options FDT # Disable CP14 work in DDB as TZ won't let us by default options ARM_FORCE_DBG_MONITOR_DISABLE + +# USB PHY support +device qcom_ipq4018_hs_usbphy +device qcom_ipq4018_ss_usbphy diff --git a/sys/arm/qualcomm/ipq4018_usb_hs_phy.c b/sys/arm/qualcomm/ipq4018_usb_hs_phy.c new file mode 100644 index 000000000000..8e03d2f27e6f --- /dev/null +++ b/sys/arm/qualcomm/ipq4018_usb_hs_phy.c @@ -0,0 +1,236 @@ +/*- + * SPDX-License-Identifier: BSD-2-Clause-FreeBSD + * + * Copyright (c) 2019 Michal Meloun <[email protected]> + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
