Switch to using the device-managed of_iomap helper to avoid leaking memory on probe deferral and driver unbind. Note that this helper checks for already reserved regions and may fail if there are multiple devices claiming the same memory.

Make sure that the (otherwise) optional pcs_misc IO region has been provided in case the configuration specifies a corresponding initialisation table to avoid crashing with malformed device trees. Note that the related debug message is now superfluous as the region is only used when the configuration has a pcs_misc table.

Drop the unused and incomplete runtime PM implementation, which was only used by USB PHYs before splitting the QMP driver.

Each of the CPSW5G ports in J7200 support additional modes like QSGMII. Add a new compatible for J7200 to support the additional modes. In TI's J7200, each of the CPSW5G ethernet interfaces can act as a QSGMII or QSGMII-SUB port. The QSGMII interface is responsible for performing auto-negotiation between the MAC and the PHY while the rest of the interfaces are designated as QSGMII-SUB interfaces, indicating that they will not be taking part in the auto-negotiation process. To indicate the interface which will serve as the main QSGMII interface, add a property "ti,qsgmii-main-ports", whose value indicates the port number of the interface which shall serve as the main QSGMII interface. The rest of the interfaces are then assigned QSGMII-SUB mode by default. The property "ti,qsgmii-main-ports" is used to configure the CTRLMMR_ENETx_CTRL register. Depending on the device, it is possible for more than one QSGMII main port to exist. Thus, the property "ti,qsgmii-main-ports" is defined as an array of values in order to reuse the property for other devices. Signed-off-by:

The serdes driver contains also a mux to decide which interface type to use. Currently the driver supports GMII/SGMII/QSGMII and partially RGMII. As it doesn't support all the other RGMII interfaces like RGMII_TXID/RXID/ID and it could run only at 1G. Therefore extend this for all the other speeds(10/100) and also allow the other interfaces.

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. Fixes: 8dc60f8d ("phy: rockchip-inno-usb2: Sync initial otg state") Reported-by:

When the platform was booted with the involved clocks enabled the clk_set_rate() of the link and pixel clocks will perculate to the children, which will fail to update because the PHY driver has just shut down the PLL.
