phy: rockchip-snps-pcie3: only look for rockchip,pipe-grf on rk3588

2022-09-29T06:13:04Z

The rockchip,pipe-grf property is only used on rk3588, but not on rk3568. Therefore this property is not present on rk3568 devices, leading to the following message: rockchip-snps-pcie3-phy fe8c0000.phy: failed to find rockchip,pipe_grf regmap Fix that by only looking for this property on rk3588.

phy: rockchip: inno-dsidphy: Add support for rk3568

2022-09-20T06:09:47Z

Add support for the Rockchip RK3568 DSI-DPHY. Registers were taken from the BSP kernel driver and wherever possible cross referenced with the TRM. Refactor the code to allow the different compatible strings to set either a max 1GHz timing table (all existing hardware) or a max 2.5GHz timing table (the new RK356x). This works (for me) on both an RK3326 (PX30) and a new RK3566 device.

phy: rockchip-inno-usb2: Return zero after otg sync

2022-09-04T15:23:40Z

The otg sync state patch reuses the ret variable, but fails to set it to zero after use. This leads to a situation when the otg port is in peripheral mode where the otg phy aborts halfway through setup. It also fails to account for a failure to register the extcon notifier. Fix this by using our own variable and skipping otg sync in case of failure.

phy: rockchip: Support PCIe v3

2022-09-04T15:05:48Z

RK3568 supports PCIe v3 using not Combphy like PCIe v2 on rk3566. It use a dedicated PCIe-phy. Add support for this. Initial support by Shawn Lin, modifications by Peter Geis and Frank Wunderlich. Add data-lanes property for splitting pcie-lanes across controllers. The data-lanes is an array where x=0 means lane is disabled and x > 0 means controller x is assigned to phy lane.

phy: rockchip: add support for the rk356x variant to rockchip-inno-csidphy

2022-09-02T17:30:47Z

This adds support for variant found in Rockchip RK356x SoCs. Note that only the basic operating mode is supported, in which all four CSI lines are controlled by the Rockchip ISP.

phy: rockchip-inno-usb2: Ignore OTG IRQs in host mode

2022-07-15T11:50:04Z

When the OTG port is fixed to host mode, the driver does not request its IRQs, nor does it enable those IRQs in hardware. Similarly, the driver should ignore the OTG port IRQs when handling the shared interrupt. Otherwise, it would update the extcon based on an ID pin which may be in an undefined state, or try to queue a uninitialized work item.

phy: rockchip-inno-usb2: Sync initial otg state

2022-07-05T07:26:53Z

The initial otg state for the phy defaults to device mode. The actual state isn't detected until an ID IRQ fires. Fix this by syncing the ID state during initialization.
