2021-06-14phy: phy-can-transceiver: Add support for generic CAN transceiver driverAswath Govindraju
The driver adds support for generic CAN transceivers. Currently the modes supported by this driver are standby and normal modes for TI TCAN1042 and TCAN1043 CAN transceivers. The transceiver is modelled as a phy with pins controlled by gpios, to put the transceiver in various device functional modes. It also gets the phy attribute max_link_rate for the usage of CAN drivers.

To support XUSB host controller ELPG, this commit moves VBUS control .phy_power_on()/.phy_power_off() to .phy_init()/.phy_exit(). When XUSB host controller enters ELPG, host driver invokes .phy_power_off(), VBUS should remain ON so that USB devices will not disconnect. VBUS can be turned OFF when host driver invokes .phy_exit() which indicates disabling a USB port.

2021-06-03phy: tegra: xusb: Rearrange UPHY init on Tegra210JC Kuo
This commit is a preparation for enabling XUSB SC7 support. It rearranges Tegra210 XUSB PADCTL UPHY initialization sequence, for the following reasons: 1. PLLE hardware power sequencer has to be enabled only after both PEX UPHY PLL and SATA UPHY PLL are initialized. tegra210_uphy_init() -> tegra210_pex_uphy_enable() -> tegra210_sata_uphy_enable() -> tegra210_plle_hw_sequence_start() -> tegra210_aux_mux_lp0_clamp_disable() 2. At cold boot and SC7 exit, the following bits must be cleared after PEX/SATA lanes are out of IDDQ (IDDQ_DISABLE=1). a. XUSB_PADCTL_ELPG_PROGRAM1_AUX_MUX_LP0_CLAMP_EN, b. XUSB_PADCTL_ELPG_PROGRAM1_AUX_MUX_LP0_CLAMP_EN_EARLY c. XUSB_PADCTL_ELPG_PROGRAM1_AUX_MUX_LP0_VCORE_DOWN tegra210_pex_uphy_enable() and tegra210_sata_uphy_enable() are in charge of bringing lanes out of IDDQ, and then AUX_MUX_LP0_* bits will be cleared by tegra210_aux_mux_lp0_clamp_disable(). 3. Once UPHY PLL hardware power sequencer is enabled, do not assert reset to PEX/SATA PLLs, otherwise UPHY PLL operation will be broken.

2021-06-03phy: tegra: xusb: Move usb3 port init for Tegra210JC Kuo
The programming sequence in tegra210_usb3_port_enable() is required for both cold boot and SC7 exit, and must be performed only after PEX/SATA UPHY is initialized. Therefore, this commit moves the programming sequence to tegra210_usb3_phy_power_on(). PCIE/SATA phy .power_on() stub will invoke tegra210_usb3_phy_power_on() if the lane is assigned for XUSB super-speed.

2021-04-16phy: phy-twl4030-usb: Fix possible use-after-free in twl4030_usb_remove()Yang Yingliang
This driver's remove path calls cancel_delayed_work(). However, that function does not wait until the work function finishes. This means that the callback function may still be running after the driver's remove function has finished, which would result in a use-after-free. Fix by calling cancel_delayed_work_sync(), which ensures that the work is properly cancelled, no longer running, and unable to re-schedule itself.
