usb: dwc3: select CONFIG_REGMAP_MMIO

2019-11-12T18:27:55+00:00

[ Upstream commit a51bab592fbbef10f0e42a8aed86adfbf6a68fa7 ] After many randconfig builds, one configuration caused a link error with dwc3-meson-g12a lacking the regmap-mmio code: drivers/usb/dwc3/dwc3-meson-g12a.o: In function `dwc3_meson_g12a_probe': dwc3-meson-g12a.c:(.text+0x9f): undefined reference to `__devm_regmap_init_mmio_clk' Add the select statement that we have for all other users of that dependency.

usb: dwc3: qcom: Add support for booting with ACPI

2019-06-18T08:58:29+00:00

In Linux, the DWC3 core exists as its own independent platform device. Thus when describing relationships in Device Tree, the current default boot configuration table option, the DWC3 core often resides as a child of the platform specific node. Both of which are given their own address space descriptions and the drivers can be mostly agnostic to each other. However, other Operating Systems have taken a more monolithic approach, which is evident in the configuration ACPI tables for the Qualcomm Snapdragon SDM850, where all DWC3 (core and platform) components are described under a single IO memory region. To ensure successful booting using the supplied ACPI tables, we need to devise a way to chop up the address regions provided and subsequently register the DWC3 core with the resultant information, which is precisely what this patch aims to achieve.

usb: dwc3: Add Amlogic G12A DWC3 glue

2019-05-03T06:13:47+00:00

Adds support for Amlogic G12A USB Control Glue HW. The Amlogic G12A SoC Family embeds 2 USB Controllers : - a DWC3 IP configured as Host for USB2 and USB3 - a DWC2 IP configured as Peripheral USB2 Only A glue connects these both controllers to 2 USB2 PHYs, and optionnally to an USB3+PCIE Combo PHY shared with the PCIE controller. The Glue configures the UTMI 8bit interfaces for the USB2 PHYs, including routing of the OTG PHY between the DWC3 and DWC2 controllers, and setups the on-chip OTG mode selection for this PHY. This drivers supports the on-probe setup of the OTG mode, and manually via a debugfs interface. The IRQ mode change detect is yet to be added in a future patchset, mainly due to lack of hardware to validate on.

usb: dwc3: Add Qualcomm DWC3 glue driver

2018-05-15T07:20:13+00:00

DWC3 controller on Qualcomm SOCs has a Qscratch wrapper. Some of its uses are described below resulting in need to have a separate glue driver instead of using dwc3-of-simple: - It exposes register interface to override vbus-override and lane0-pwr-present signals going to hardware. These must be updated in peripheral mode for DWC3 if vbus lines are not connected to hardware block. Otherwise RX termination in SS mode or DP pull-up is not applied by device controller. - pwr_events_irq_stat support to check if USB2 PHY is in L2 state before glue driver proceeds with suspend. - Support for wakeup interrupts lines that are asserted whenever there is any wakeup event on USB3 or USB2 bus. - Support to replace pip3 clock going to DWC3 with utmi clock for hardware configuration where SSPHY is not used with DWC3.
