phy: renesas: rcar-gen3-usb2: add is_otg_channel to use "role" sysfs

2018-09-25T10:40:12+00:00

Even if a board doesn't have otg pins connection, this hardware can
change the role by a register setting. So, this patch adds
"is_otg_channel" for it.

phy: renesas: rcar-gen3-usb2: add conditions for uses_otg_pins == false

2018-09-25T10:40:11+00:00

If uses_otg_pins is set to false, this driver 1) should disable otg
related interruptions, and 2) should not get ID pin signal, to avoid
unexpected behaviors. So, this patch adds conditions for it.

phy: renesas: rcar-gen3-usb2: change a condition "dr_mode"

2018-09-25T10:40:11+00:00

This patch changes a condition about dr_mode. If a device node has
any dr_mode ("host", "peripheral" or "otg"), this driver allows to
set "is_otg_channel" to true. Also, this patch keeps the dr_mode
value for future use.

phy: renesas: rcar-gen3-usb2: Check a property to use otg pins

2018-09-25T10:40:10+00:00

Since All R-Car Gen3 SoCs have dedicated otg pins actually but
some boards don't use the otg pins (e.g. R-Car D3 Draak and R-Car E3
Ebisu), the driver should not choose SoC model base by using
rcar_gen3_phy_usb2_match_table's data. So, this patch checks a
"renesas,no-otg-pins" property to set the "uses_otg_pins".

Note that since r8a77995-draak.dts and r8a77990-ebisu.dts don't have
'dr_mode = "otg";' for now, if we apply this patch, no behavior
changes (the value of "uses_otg_pins" is false).

phy: renesas: rcar-gen3-usb2: Rename has_otg_pins to uses_otg_pins

2018-09-25T10:40:09+00:00

Since R-Car E3 and D3 have dedicated otg pins actually, "has_otg_pins"
is possible to misread in the future. So, this patch renames
has_otg_pins to uses_otg_pins.

phy: renesas: rcar-gen3-usb2: fix vbus_ctrl for role sysfs

2018-09-25T10:40:09+00:00

This patch fixes and issue that the vbus_ctrl is disabled by
rcar_gen3_init_from_a_peri_to_a_host(), so a usb host cannot
supply the vbus.

Note that this condition will exit when the otg irq happens
even if we don't apply this patch.

phy: Renesas R-Car gen3 PCIe PHY driver

2018-07-10T08:15:11+00:00

This PHY is  still  mostly undocumented -- the only documented registers
exist on R-Car V3H (R8A77980) SoC where this PHY stays in a powered-down
state after a reset and thus  we  must power it up for PCIe to work...
