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 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
