phy: qcom: Add SNPS femto v2 USB HS phy

2024-04-04T15:46:46Z

Some Qualcomm SoCs newer than SDM845 feature a so-called "7nm phy" driver, notable the SM8250 SoC which will gain U-Boot support in upcoming patches. Introduce a driver based on the Linux driver.

phy: qcom: add Qualcomm QUSB2 USB PHY driver

2024-04-04T15:46:46Z

The Snapdragon 845 and several other Qualcomm SoCs feature this USB high-speed phy. Add a driver for it based on the Linux driver, with support for the SDM845, and the QCM2290 and SM6115 SoCs which will gain support in U-Boot in future patches.

phy: phy-imx8m-pcie: Add support for i.MX8M{M/P} PCIe PHY

2024-03-24T16:35:59Z

Add initial support for i.MX8M{M/P} PCIe PHY. On i.MX8M{M/P} SoCs PCIe PHY initialization moved to this standalone PHY driver. Inspired from counterpart Linux kernel v6.8-rc3 driver: drivers/phy/freescale/phy-fsl-imx8m-pcie.c. Use last Linux kernel driver reference commit 7559e7572c03 ("phy: Explicitly include correct DT includes").

phy: rockchip-inno-usb2: Limit changes made to regs

2024-03-14T03:48:40Z

The USB2PHY regs already contain working default reset values for RK3328 and RK35xx as evidenced by the fact that this driver never has changed a single value for these SoCs. Reduce to only configure utmi_suspend_n and utmi_sel bits similar to what is currently done on RK3399. Also add missing clkout_ctl for RK3588. When enabled utmi_suspend_n is changed to normal mode and utmi_sel to use otg/host controller utmi interface to phy. When disabled utmi_suspend_n is changed to suspend mode and utmi_sel to use GRF utmi interface to phy. Signed-off-by: Jonas Karlman

phy: rockchip-inno-usb2: Write to correct GRF

2024-03-14T03:48:40Z

On RK3399 the USB2PHY regs are located in the common GRF, remaining SoCs that is supported by this driver have the USB2PHY regs in a different GRF. When support for RK356x, RK3588 and RK3328 was added this driver was never updated to use correct GRF and have instead incorrectly written to wrong GRF for these SoCs. The default reset values for the USB2PHY have made USB mostly working even when wrong GRF was used, however, following have been observed: scanning bus usb@fd840000 for devices... ERROR: USB-error: DEVICENOTRESPONDING: Device did not respond to token (IN) or did not provide a handshake (OUT) (5) ERROR: USB-error: DEVICENOTRESPONDING: Device did not respond to token (IN) or did not provide a handshake (OUT) (5) unable to get device descriptor (error=-1) Fix this by using a regmap from rockchip,usbgrf prop and fall back to getting a regmap for parent udevice instead of always getting the common GRF. Also protect against accidental clear of bit 0 in a reg with offset 0, only bind driver to enabled otg/host-ports and remove unused headers.

board: dragonboard410c: upstream DT compat

2024-03-01T14:44:37Z

Use the root compatible strings from upstream Linux, add missing '#clock-cells' property to the gcc node. Adjust some of the msm8916/apq8016 drivers to use the correct upstream compatible properties and DT bindings. This prepares us to switch to upstream DT in a future patch.
