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 to /lib/firmware/cdn/dptx.bin. The uCPU in charge of aux communication and link training, the host use mailbox to communicate with the ucpu.
The PHY driver 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 PHY and DP controller.
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: https://github.com/markyzq/kernel-drm-rockchip/tree/drm-rockchip-next-2016-0...
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.
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>; - use EXTCON_DISP_DP and EXTCON_DISP_DP_ALT cable to get dp port state. - reset spdif before config it - modify the firmware clk to 100Mhz - retry load firmware if fw file is requested too early
Changes in v2: - add some registers description - select RESET_CONTROLLER - alphabetic order - modify some spelling mistakes - make mode cleaner - use bool for enable/disable - check all of the return value - return a better err number - use more readx_poll_timeout() - clk_disable_unprepare(tcphy->clk_ref); - remove unuse functions, rockchip_typec_phy_power_on/off - remove unnecessary typecast from void * - use dts node to distinguish between phys. - Alphabetic order - remove excess error message - use define clk_rate - check all return value - remove dev_set_name(dp->dev, "cdn-dp"); - use schedule_delayed_work - remove never-called functions - remove some unnecessary ()
Changes in v1: - add extcon node description - move the registers in phy driver - remove the suffix of reset - update the licence note - init core clock to 50MHz - use extcon API - remove unused global - add some comments for magic num - change usleep_range(1000, 2000) tousleep_range(1000, 1050) - remove __func__ from dev_err - return err number when get clk failed - remove ADDR_ADJ define - use devm_clk_get(&pdev->dev, "tcpdcore") - add extcon node description - add #sound-dai-cells description - use extcon API - use hdmi-codec for the DP Asoc - do not initialize the "ret" - printk a err log when drm_of_encoder_active_endpoint_id - modify the dclk pin_pol to a single line
