2020-03-19phy: tegra: xusb: Don't warn on probe deferJon Hunter
Deferred probe is an expected return value for tegra_fuse_readl(). Given that the driver deals with it properly, there's no need to output a warning that may potentially confuse users.

2020-03-19phy: tegra: xusb: Add Tegra194 supportJC Kuo
Add support for the XUSB pad controller found on Tegra194 SoCs. It is mostly similar to the same IP found on Tegra186, but the number of pads exposed differs, as do the programming sequences. Because most of the Tegra194 XUSB PADCTL registers definition and programming sequence are the same as Tegra186, Tegra194 XUSB PADCTL can share the same driver, xusb-tegra186.c, with Tegra186 XUSB PADCTL. Tegra194 XUSB PADCTL supports up to USB 3.1 Gen 2 speed, however, it is possible for some platforms have long signal trace that could not provide sufficient electrical environment for Gen 2 speed. This patch adds a "maximum-speed" property to usb3 ports which can be used to specify the maximum supported speed for any particular USB 3.1 port. For a port that is not capable of SuperSpeedPlus, "maximum-speed" property should carry "super-speed".

2020-02-21phy: brcm-sata: Correct MDIO operations for 40nm platformsFlorian Fainelli
The logic to write to MDIO registers on 40nm platforms was wrong because it would use the port number as an offset from the base address rather than the bank address of the PHY. This is hardly noticeable because the only programming we do is enabling SSC or not, which is not really causing an observable functional change. Correct that mistake by passing down the struct brcm_sata_port structure down to the brcm_sata_mdio_wr() and brcm_sata_mdio_rd() functions and do the proper offsetting for 28nm, respectively 40nm platforms from there. This means that brcm_sata_pcb_base() is now useless and is therefore removed.

I've noticed that when writing data to the modem the writes can time out at some point eventually. Looks like kicking the modem idle GPIO every 600 ms instead of once a second fixes the issue. Note that this rate is different from our runtime PM autosuspend rate MDM6600_MODEM_IDLE_DELAY_MS that we still want to keep at 1 second, so let's add a separate define for PHY_MDM6600_IDLE_KICK_MS.

2020-01-08phy: usb: Add support for wake and USB low power mode for 7211 S2/S5Al Cooper
Add support for 7211 USB wake. Disable all possible 7211 USB logic for S2/S5 if USB wake is not enabled. On the 7211, the XHCI wake signal was not connected properly and only goes to the USB1_USB1_CTRL_TP_DIAG1 diagonstic register. The workaround is to have VPU code running that polls for the proper bit in the DIAG register and to wake the system when the bit is asserted.

2020-01-08phy: usb: PHY's MDIO registers not accessible without device installedAl Cooper
When there is no device connected and FSM is enabled, the XHCI puts the PHY into suspend mode. When the PHY is put into suspend mode the USB LDO powers down the PHY. This causes the MDIO to be inaccessible and its registers reset to default. The fix is to disable FSM.
