Usually the digital and analog phys use the same reference clock, but some platforms have two separate reference clocks for each of them, so add another optional clock to support them. In order to keep the clock names consistent with PHY IP's, change the da_ref for analog phy and ref clock for digital phy. Signed-off-by:

The u3phya_ref clock is already moved into sub-node, and renamed as ref clock, no used anymore now, so remove it, this can avoid confusion when support new platforms Signed-off-by:

Sometimes the reference clock of USB3 PHY comes from oscillator directly, and no need refer to a fixed-clock in DTS anymore if make it optional. Signed-off-by:

This is used to tune J-K voltage by internal R (resistance), the range is [0, 31], the resistance value is about 6.9K ohm for 0, 3.8K ohm for 31, and the step is 1K ohm Signed-off-by:

This is used to tune the threshold of disconnect, the index range is [0, 15], the threshold voltage is about 400mV for 0, 700mV for 15, and the step is 20mV. Signed-off-by:

The PCIe PHY initialization requires the attached device to be present, which is primarily achieved by the PCI controller driver. So move the logic from init/exit to power_on/power_off. Signed-off-by:

Since this phy is shared by multiple devices including USB and PCIe, it is necessary to determine which device use this phy. This patch adds SoC-dependent functions to determine a device using this phy. When there is 'socionext,syscon' property in the pcie-phy node, the driver calls SoC-dependt function instead of checking .has_syscon in SoC-dependent data. The function configures the system controller to use phy for PCIe. Signed-off-by:

Add legacy SoC support that needs to manage gio clock and reset and to skip setting unimplemented phy parameters. This supports Pro5. This specifies only 1 port use because Pro5 doesn't set it in the power-on sequence. Signed-off-by:

In case of using default parameters, communication failure might occur in rare cases. This sets Rx sync mode parameter to avoid the issue. Signed-off-by:

Pro5 SoC has same scheme of USB3 ss-phy as Pro4, so the data for Pro5 is equivalent to Pro4. Signed-off-by:

Kunihiko Hayashi authored
This adds compatible string for Pro5 SoC that needs to manage gio clock and reset. And Pro4 SoC uses USB2 PHY instead of USB3 HS-PHY, so this removes Pro4 description from usb3-hsphy. Signed-off-by:

The support for the 14nm MSM8996 UFS PHY is currently handled by the UFS-specific 14nm QMP driver, due to the earlier need for additional operations beyond the standard PHY API. Add support for this PHY to the common QMP driver, to allow us to remove the old driver. Acked-by:

Rename Cadence DP PHY driver from phy-cadence-dp to phy-cadence-torrent to make it more generic for future use. Modifiy Makefile and Kconfig accordingly. Also, change driver compatible from "cdns,dp-phy" to "cdns,torrent-phy".This will not affect ABI as the driver has never been functional, and therefore do not exist in any active use case.

- Add Cadence MHDP PHY bindings in YAML format. - Add Torrent PHY reference clock bindings. - Add sub-node bindings for each group of PHY lanes based on PHY type. Each sub-node includes properties such as master lane number, link reset, phy type, number of lanes etc. - Add reset support including PHY reset and individual lane reset. - Add a new compatible string used for TI SoCs using Torrent PHY. This will not affect ABI as the driver has never been functional, and therefore do not exist in any active use case. Signed-off-by:
