2021-03-31phy: cadence: Sierra: Explicitly request exclusive reset controlKishon Vijay Abraham I
No functional change. Since the reset controls obtained in Sierra is exclusively used by the Sierra device, use exclusive reset control request API calls.

2021-03-31phy: ti: j721e-wiz: Get PHY properties only for "phy" or "link" subnodeKishon Vijay Abraham I
"serdes" node (child node of WIZ) can have sub-nodes for representing links or it can have sub-nodes for representing the various clocks within the serdes. Instead of trying to read "reg" from every child node used for assigning "lane_phy_type", read only if the child node's name is "phy" or "link" subnode. Ideally all PHY dt nodes should have node name as "phy", however existing devicetree used "link" as subnode. So in order to maintain old DT compatibility get PHY properties for "phy" or "link" subnode.

Cadence Sierra PHY driver registers PHY using devm_phy_create() for all sub-nodes of Sierra device tree node. However Sierra device tree node can have sub-nodes for the various clocks in addtion to the PHY. Use devm_phy_create() only for nodes with name "phy" (or "link" for old device tree) which represent the actual PHY.

Invoke wiz_init() before configuring anything else in Sierra/Torrent (invoked as part of of_platform_device_create()). wiz_init() resets the SERDES device and any configuration done in the probe() of Sierra/Torrent will be lost.

commit 091876cc355d ("phy: ti: j721e-wiz: Add support for WIZ module present in TI J721E SoC") modeled the internal clocks depending on the subnodes that are populated in device tree. However recent discussions in the mailing list [1] suggested to just add #clock cells in the parent DT node and model the clocks within the driver. Model the mux clocks without device tree input for AM64x SoC. Don't remove the earlier design since DT nodes for J7200 and J721e are already upstreamed.

2021-03-15phy: phy-brcm-usb: select SOC_BRCMSTB on brcmstb onlyRafał Miłecki
phy-brcm-usb has some conditional init code required on selected brcmstb devices. Execution of that code depends on family / product detected by brcmstb soc code. For ARCH_BCM4908 brcmstb soc code always return 0 values as ids. Don't bother selecting & compiling that redundant driver.

usbphyc provides a unique clock called ck_usbo_48m. STM32 USB OTG needs a 48Mhz clock (utmifs_clk48) for Full-Speed operation. ck_usbo_48m is a possible parent clock for USB OTG 48Mhz clock. ck_usbo_48m is available as soon as the PLL is enabled.

2021-03-12phy: tusb1210: use bitmasks to set VENDOR_SPECIFIC2Liam Beguin
Start by reading the content of the VENDOR_SPECIFIC2 register and update each bit field based on device properties when defined. The use of bit masks prevents fields from overriding each other and enables users to clear bits which are set by default, like datapolarity in this instance.
