phy: rockchip-usb: add usb-uart setup for rk3188

2018-09-25T10:40:13+00:00

The rk3188 also supports bringing the uart2 out through the usb dm+dp pins, so add the necessary setup for it. rk3066 does not seem to support usb-uart functionality and this particular phy was only used on older Rockchip socs, so this leaves room for a bit of cleanup as well, as there most likely won't be new additions in the driver.

phy: Convert to using %pOFn instead of device_node.name

2018-09-25T10:40:07+00:00

In preparation to remove the node name pointer from struct device_node, convert printf users to use the %pOFn format specifier. Cc: Kishon Vijay Abraham I Cc: linux-arm-kernel@lists.infradead.org Signed-off-by: Rob Herring Signed-off-by: Kishon Vijay Abraham I

phy: rockchip-typec: fall back to working in host-mode if extcon is missing.

2018-03-16T11:25:37+00:00

Right now the rockchip type-c phy does fail probing when no extcon is detected. Some boards get the cable-state via the extcon interface and have this supported, other boards seem to use the fusb302 chip or another but the driver currently does not seem to utilize the extcon interface to report the cable-state. And, other, just connect the type-c to a standard USB-A port so use no controller at all. A missing extcon shouldn't fail to probe, instead, should just fall back to working in host-mode if it cannot get the extcon.

phy: rockchip-typec: support DP phy switch

2018-03-16T11:25:35+00:00

There are 2 Type-c PHYs in RK3399, but only one DP controller. Hence only one PHY can connect to DP controller at one time, the other should be disconnected. The GRF_SOC_CON26 register has a switch bit to do it, set this bit means enable PHY 1, clear this bit means enable PHY 0.

phy: rockchip-typec: force to USB2 if DP at 4 lanes mode

2018-03-16T11:25:34+00:00

The usb3tousb2_en BIT will be clear to 0 in probe(), it make USB controller work at USB3 mode, and if the USB phy is turned on with DP only mode(4 lanes DP), the rockchip_usb3_phy_power_on() will return directly, so usb3_host_disable and usb3_host_port these 2 BIT will keep a same value as coreboot. In coreboot, these 3 BITs are set as USB2 mode, but now one of the bits is changed to USB3, it make USB controller work at a unknown status. These 3 BITs should be changed to USB2, if the Type-C works at 4 lanes mode, and then switch it back to USB3 mode, when USB disconnect.

phy: rockchip-typec: enable usb3 host during usb3 phy power on

2018-03-16T11:25:33+00:00

We have forced usb3 to work in usb2 only mode in firmware by setting usb3tousb2_en (bit3 of GRF_USB3PHY0/1_CON0) to 1, and setting host_u3_port_disable (bit0 of GRF_USB3OTG0/1_CON1) to 1 and host_u3_port (bit15~12 of GRF_USB3OTG0/1_CON1) to 0. So we need to re-enable usb3 host. Note that the RK3399 TRM suggests that we should keep the whole usb3 controller in reset for the duration of the Type-C PHY initialization. However, it's hard to assert the reset in the current framework of reset. And according to the TRM, it doesn't require that we should clear the usb3tousb2 bit before pipe ready. So let's enable the usb3 host after pipe ready to avoid the Type-C PHY initialization failure.

phy: rockchip-typec: deprecate some DT properties for various register fields.

2018-03-16T11:25:31+00:00

Adding properties for various register fields in the DT doesn't scale and this information should be in the driver instead. Before this patch these registers (description below) were specified in the DT, every register node contained 3 sections: offset, enable bit, write mask bit. - rockchip,typec-conn-dir : the register of type-c connector direction, for type-c phy0, it must be <0xe580 0 16>; for type-c phy1, it must be <0xe58c 0 16>; - rockchip,usb3tousb2-en : the register of type-c force usb3 to usb2 enable control. for type-c phy0, it must be <0xe580 3 19>; for type-c phy1, it must be <0xe58c 3 19>; - rockchip,external-psm : the register of type-c phy external psm clock selection. for type-c phy0, it must be <0xe588 14 30>; for type-c phy1, it must be <0xe594 14 30>; - rockchip,pipe-status : the register of type-c phy pipe status. for type-c phy0, it must be <0xe5c0 0 0>; for type-c phy1, it must be <0xe5c0 16 16>; After this patch these register definitions are in the driver. So can be removed from the DT. Note that there are 2 type-c phys for RK3399 with different offsets, the driver checks the phy base address of the running instance and applies the right offsets.
