Sorry, forgot to add the reviewed-by and tested-by tags, so resend Hi all This series patch is for rockchip Type-C phy and DisplayPort controller driver. The USB Type-C PHY is designed to support the USB3 and DP applications. The PHY basically has two main components: USB3 and DisplyPort. USB3 operates in SuperSpeed mode and the DP can operate at RBR, HBR and HBR2 data rates. The Type-C cable orientation detection and Power Delivery (PD) is accomplished using a PD PHY or a exernal PD chip. The DP controller is compliant with DisplayPort Specification, Version 1.3, This IP is compatible with the rockchip type-c PHY IP. There is a uCPU in DP controller, it need a firmware to work, please put the firmware file[0] rockchip/dptx.bin to /lib/firmware/rockchip/dptx.bin. The uCPU in charge of aux communication and link training, the host use mailbox to communicate with the ucpu. The DP contoller has register a notification with extcon API, to get the alt mode from PD, the PD driver need call the devm_extcon_dev_allocate to create a extcon device and use extcon_set_state to notify DP controller. And call extcon_set_cable_property to set orientation. About the DP audio, cdn-dp registered 2 DAIs: 0 is I2S, 1 is SPDIF. We can reference them in simple-card. This series is based on Mark Yao's branch[1] and Chanwoo Choi's extcon-next branch[2], and the Heiko's clk patch[3]. I test this patches on the rk3399-evb board, with a fusb302 driver, this branch has no rk3399.dtsi, so the patch about dts is not included in this series. >From V9, the Type-C PHY is split into two PHYs: DP and USB3. The PHY will be init, no matter which PHY be power_on. The DP module will enter A2 mode (standby mode) after phy_init, if DP PHY is powered on, the DP module will enter to A0 mode(running mode). Then if DP PHY is powered off, DP module will back to A2 mode. If everything is un-plugged, phy will be deinit.

to earlier place. in rockchip_usb3_phy_power_off - better mutex lock for phy mode and flip - split the Type-C PHY into two PHYs: USB3 and DP - change #phy-cells to 1 - modify the reference phy = <&tcphy0 0>, <&tcphy1 0>; - do not need reset the phy before power_on - add a orientation information for set_capability - retry to read dpcd in 10 seconds Changes in v8: - set the default cable id to EXTCON_USB_HOST - optimization Error log - optimization the err log Changes in v7: - support new API of extcon - support firmware standby when no dptx connection - optimization the calculation of tu size and valid symbol Changes in v6: - add assigned-clocks and assigned-clock-rates - delete the support of PIN_ASSIGN_A/B - set the default mode to MODE_DFP_USB - disable DP PLL at USB3 only mode - add assigned-clocks and assigned-clock-rates - add power-domains - add a port struct - select SND_SOC_HDMI_CODEC - force reset the phy when hpd detected Changes in v5: - support get property from extcon - remove PIN ASSIGN A/B support - alphabetical order - do not use long, use u32 or u64 - return MODE_CLOCK_HIGH when requested > actual - Optimized Coding Style - add a formula to get better tu size and symbol value. - modify according to Sean Paul's comments - fixed the fw_wait always 0 Changes in v4: - add a #phy-cells node - select EXTCON - use phy framework to control the USB3 and DP function - rename PIN_MAP_ to PIN_ASSIGN_ - add a reset node - support 2 phys - use phy framework to control DP phy - support 2 phys Changes in v3: - use compatible: rockchip,rk3399-typec-phy - use dashes instead of underscores. - remove the phy framework(Kishon Vijay Abraham I) - add parentheses around the macro - use a single space between type and name - add spaces after opening and before closing braces. - use u16 for register value - remove type-c phy header file - CodingStyle optimization - use some cable extcon to get type-c port information - add a extcon to notify Display Port - add SoC specific compatible string - remove reg = <1>;
