phy: renesas: rcar-gen3-usb2: follow the hardware manual procedure

2018-12-12T04:31:38Z

This patch modifies rcar_gen3_init_otg() procedure to follow Figure 73.4 of "R-Car Series, 3rd Generation User's Manual: Hardware Rev.1.00". Signed-off-by: Yoshihiro Shimoda Signed-off-by: Kishon Vijay Abraham I

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

2018-09-25T10:40:12Z

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. Signed-off-by: Yoshihiro Shimoda Reviewed-by: Simon Horman Signed-off-by: Kishon Vijay Abraham I

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

2018-09-25T10:40:11Z

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. Signed-off-by: Yoshihiro Shimoda Reviewed-by: Simon Horman Signed-off-by: Kishon Vijay Abraham I

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

2018-09-25T10:40:11Z

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. Signed-off-by: Yoshihiro Shimoda Reviewed-by: Simon Horman Signed-off-by: Kishon Vijay Abraham I

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

2018-09-25T10:40:10Z

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

2018-09-25T10:40:09Z

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. Signed-off-by: Yoshihiro Shimoda Reviewed-by: Simon Horman Signed-off-by: Kishon Vijay Abraham I

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

2018-09-25T10:40:09Z

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.
