phy: rockchip-inno-usb2: Ignore OTG IRQs in host mode

2022-08-17T13:15:33+00:00

[ Upstream commit fd7d47484125c7d04578de9294faa7fec6e5df0a ]

When the OTG port is fixed to host mode, the driver does not request its
IRQs, nor does it enable those IRQs in hardware. Similarly, the driver
should ignore the OTG port IRQs when handling the shared interrupt.

Otherwise, it would update the extcon based on an ID pin which may be in
an undefined state, or try to queue a uninitialized work item.

phy: stm32: fix error return in stm32_usbphyc_phy_init

2022-08-17T13:15:33+00:00

[ Upstream commit 32b378a9179ae4db61cfc5d502717214e6cd1e1c ]

Error code is overridden, in case the PLL doesn't lock. So, the USB
initialization can continue. This leads to a platform freeze.
This can be avoided by returning proper error code to avoid USB probe
freezing the platform. It also displays proper errors in log.

phy: qcom-qmp: fix the QSERDES_V5_COM_CMN_MODE register

2022-08-17T13:15:28+00:00

[ Upstream commit 488987b2d5cade4e7680f7e81590435a848d1fa9 ]

Change QSERDES_V5_COM_CMN_MODE to be defined to 0x1a0 rather than 0x1a4.
The only user of this register name (sm8450_qmp_gen4x2_pcie_serdes_tbl)
should use the 0x1a0 register, as stated in the downstream dtsi tree.

phy: rockchip-inno-usb2: Sync initial otg state

2022-08-17T13:15:27+00:00

[ Upstream commit 8dc60f8da22fdbaa1fafcfb5ff6d24bc9eff56aa ]

The initial otg state for the phy defaults to device mode. The actual
state isn't detected until an ID IRQ fires. Fix this by syncing the ID
state during initialization.

phy: ti: tusb1210: Don't check for write errors when powering on

2022-08-17T13:15:27+00:00

[ Upstream commit d4a0a189b72a7c98e4256292b18b67c69fbc9343 ]

On some platforms, like Intel Merrifield, the writing values during power on
may timeout:

   tusb1210 dwc3.0.auto.ulpi: error -110 writing val 0x41 to reg 0x80
   phy phy-dwc3.0.auto.ulpi.0: phy poweron failed --> -110
   dwc3 dwc3.0.auto: error -ETIMEDOUT: failed to initialize core
   dwc3: probe of dwc3.0.auto failed with error -110

which effectively fails the probe of the USB controller.
Drop the check as it was before the culprit commit (see Fixes tag).

Make sure to disable the pipe clock also if ufs-reset deassertion fails
during power on.

Note that the ufs-reset is asserted in qcom_qmp_phy_com_exit().

phy: qcom-qmp: switch to explicit reset helpers

2022-05-03T04:41:01+00:00

Switch to consistently using the explicit reset-controller API which
makes it clear that the reset controllers are used exclusively by the
PHY driver.

Note that the deprecated of_reset_control_get() and
devm_reset_control_get() are just transitional wrappers for the explicit
API so there's no functional change.
