2019-12-17dt-bindings: usb: Convert Allwinner USB PHY controller to a schemaMaxime Ripard1-68/+0
The Allwinner SoCs have a USB PHY controller that is supported in Linux, with a matching Device Tree binding. Now that we have the DT validation in place, let's convert the device tree bindings for that controller over to a YAML schemas.

2018-12-12dt-bindings: phy: add binding for Allwinner H6 USB2 PHYIcenowy Zheng1-3/+5
The USB2.0 PHY on Allwinner H6 is similar to the ones on the ones on older SoCs, but with holes in PHY number (USB1 and USB2 are missing, in which USB1 is a USB3 PHY). Add binding for the PHY.

2017-08-22dt-bindings: phy: sun4i-usb-phy: Add compatible string for A83TChen-Yu Tsai1-2/+4
The A83T has 3 USB PHYs, 1 for OTG, 1 for standard USB, 1 for USB HSIC. Add a compatible string for it, and describe the needed properties.

2017-08-22dt-bindings: phy: sun4i-usb-phy: Add property descriptions for H3Chen-Yu Tsai1-2/+6
The Allwinner H3 SoC has 4 USB PHYs, so it needs four sets of pmu regions, clocks, resets, and optional vbus properties. These were not described when the H3 compatible string was added.

2017-04-10dt: bindings: add pmu0 regs for USB PHYs on Allwinner H3/V3s/A64Icenowy Zheng1-0/+1
Allwinner H3/V3s/A64 SoCs have a special USB PHY0 that can route to two controllers: one is MUSB and the other is a EHCI/OHCI pair. When it's routed to EHCI/OHCI pair, it will needs a "pmu0" regs to tweak, like other EHCI/OHCI pairs in Allwinner SoCs. Add this to the binding of USB PHYs on Allwinner H3/V3s/A64.

2015-07-25phy-sun4i-usb: Add support for monitoring vbus via a power-supplyHans de Goede1-0/+1
On some boards there is no vbus_det gpio pin, instead vbus-detection for otg can be done via the pmic. This commit adds support for monitoring vbus_det via the power_supply exported by the pmic, enabling support for otg on these boards.

2015-07-25phy-sun4i-usb: Add support for the usb-phys on the sun8i-a33 SoCHans de Goede1-0/+1
The usb-phys on the sun8i-a33 SoC are mostly the same as sun8i-a23 but for some reason (hw bug?) the phyctl register was moved to a different address and is not initialized to 0 on reset. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
2015-07-25phy-sun4i-usb: Add support for the usb-phys on the sun8i-a23 SoCHans de Goede1-0/+2
The usb-phys on the sun8i-a23 SoC have the same setup wrt clocks as on the sun6i-a31 SoC, but there are only 2 instead of 3 like on the sun5i-a13 SoC. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
2015-07-25phy-sun4i-usb: Add id and vbus detection support for the otg phy (phy0)Hans de Goede1-2/+16
The usb0 phy is connected to an OTG controller, and as such needs some special handling: 1) It allows explicit control over the pullups, enable these on phy_init and disable them on phy_exit. 2) It has bits to signal id and vbus detect to the musb-core, add support for for monitoring id and vbus detect gpio-s for use in dual role mode, and set these bits to the correct values for operating in host only mode when no gpios are specified in the devicetree. While updating the devicetree binding documentation also add documentation for the sofar undocumented usage of regulators for vbus for all 3 phys.

2014-03-03PHY: sunxi: Add driver for sunxi usb phyHans de Goede1-0/+26
The Allwinner A1x / A2x SoCs have 2 or 3 usb phys which are all accessed through a single set of registers. Besides this there are also some other phy related bits which need poking, which are per phy, but shared between the ohci and ehci controllers, so these are also controlled from this new phy driver.
