2022-11-07phy: ti: gmii-sel: Add support for CPSW9G GMII SEL in J721eSiddharth Vadapalli1-0/+13
Each of the CPSW9G ports in J721e support additional modes like QSGMII. Add a new compatible for J721e to support the additional modes. In TI's J721e, each of the CPSW9G ethernet interfaces can act as a QSGMII main or QSGMII-SUB port. The QSGMII main 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.

2022-11-07phy: ti: gmii-sel: Update methods for fetching and using qsgmii main portSiddharth Vadapalli1-7/+22
The number of QSGMII main ports are specific to the device. TI's J7200 for which the QSGMII main port property is fetched from the device-tree has only one QSGMII main port. However, devices like TI's J721e support up to two QSGMII main ports. Thus, the existing methods for fetching and using the QSGMII main port are not scalable. Update the existing methods for handling the QSGMII main ports and its associated requirements to make it scalable for future devices.

2022-11-07phy: sun4i-usb: Add support for the H616 USB PHYAndre Przywara1-0/+12
The USB PHY used in the Allwinner H616 SoC inherits some traits from its various predecessors: it has four full PHYs like the H3, needs some extra bits to be set like the H6, and puts SIDDQ on a different bit like the A100. Plus it needs this weird PHY2 quirk. Name all those properties in a new config struct and assign a new compatible name to it.

2022-11-07phy: sun4i-usb: Introduce port2 SIDDQ quirkAndre Przywara1-0/+59
At least the Allwinner H616 SoC requires a weird quirk to make most USB PHYs work: Only port2 works out of the box, but all other ports need some help from this port2 to work correctly: The CLK_BUS_PHY2 and RST_USB_PHY2 clock and reset need to be enabled, and the SIDDQ bit in the PMU PHY control register needs to be cleared. For this register to be accessible, CLK_BUS_ECHI2 needs to be ungated. Don't ask .... Instead of disguising this as some generic feature, treat it more like a quirk (what it really is): If the quirk bit is set, and we initialise a PHY other than PHY2, ungate this one special clock, and clear the SIDDQ bit. We also pick the clock and reset from PHY2 and enable them as well.

2022-11-07phy: usb: Disable phy auto-suspendJustin Chen1-0/+6
The BDC block requires the PLL lock in order to grab the PLL clock. The phy auto-suspend feature turns off the phy when nothing is attached leading to the PLL to not lock. This leads the BDC block to grab the AUX clock instead of the PLL clock. This is not ideal, so lets turn this feature off.

Split port modes into two different variables. Supported port modes is what the hardware supports. While port mode is how the hardware is currently configured and can be dynamically changed through the sysfs. We initialize all supported port modes on init even though the port mode may not be selected because we cannot guarantee the downstream interface from the phy will be active or not. This also fixes an issue where port modes selected via sysfs were not being saved through suspend/resume.

2022-10-28phy: qcom-qmp-pcie: add config sanity checksJohan Hovold1-0/+3
The driver expects every configuration to set the pwrdn_ctrl and phy_status masks. Add some probe WARN_ON_ONCE() to probe to catch any new driver support that fails to provide them.
