phy: sun4i-usb: Use devm_gpiod_get_optional for optional GPIOs

2015-10-06T14:51:47+00:00

Both data->id_det_gpio and data->vbus_det_gpio are optional, so use
devm_gpiod_get_optional for them.

phy: Constify struct phy_ops variables

2015-08-03T13:05:09+00:00

The phy_ops variables are never modified after initialized in these
drivers, so make them const.

phy-sun4i-usb: Only check vbus-det on power-on on boards with vbus-det

2015-08-03T13:05:08+00:00

data->vbus_det is always 1 on boards without a (working) vbus-det, skip
the vbus_det test on such boards.

This fixes the sun4i usb phy code never turning on Vbus on such boards.

phy-sun4i-sub: Move vbus-detect helper functions up in the file

2015-08-03T13:05:08+00:00

Move vbus-detect helper functions up in the file, just moving some code
around, no functional changes what so ever.

phy-sun4i-usb: Add missing EXPORT_SYMBOL_GPL for sun4i_usb_phy_set_squelch_detect

2015-08-01T10:22:58+00:00

sun4i_usb_phy_set_squelch_detect is used by other code, which may be built
as a module, so it should be exported.

phy-sun4i-usb: Add support for monitoring vbus via a power-supply

2015-07-25T10:15:47+00:00

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.

phy-sun4i-usb: Add support for boards with broken Vusb-detection

2015-07-25T10:15:47+00:00

On some boards we cannot detect the presence of an external Vusb, because
e.g. the 5V of the otg connector is directly connected to the 5V of the board,
and thus is always high.

This commit adds support for using such boards by only looking at the
id-detection pin.

phy-sun4i-usb: Add support for the usb-phys on the sun8i-a33 SoC

2015-07-25T10:15:47+00:00

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.

phy-sun4i-usb: Add support for the usb-phys on the sun8i-a23 SoC

2015-07-25T10:15:47+00:00

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.
