usb: phy: tahvo: add IRQ check

2021-09-15T08:00:48+00:00

[ Upstream commit 0d45a1373e669880b8beaecc8765f44cb0241e47 ]

The driver neglects to check the result of platform_get_irq()'s call and
blithely passes the negative error codes to request_threaded_irq() (which
takes *unsigned* IRQ #), causing it to fail with -EINVAL, overriding an
original error code.  Stop calling request_threaded_irq() with the invalid
IRQ #s.

usb: phy: twl6030: add IRQ checks

[ Upstream commit 0881e22c06e66af0b64773c91c8868ead3d01aa1 ]

The driver neglects to check the result of platform_get_irq()'s calls and
blithely passes the negative error codes to request_threaded_irq() (which
takes *unsigned* IRQ #), causing them both to fail with -EINVAL, overriding
an original error code.  Stop calling request_threaded_irq() with the
invalid IRQ #s.

usb: phy: tegra: Correct definition of B_SESS_VLD_WAKEUP_EN bit

2021-07-14T15:07:41+00:00

[ Upstream commit 7917e90667bc8dce02daa3c2e6df47f6fc9481f7 ]

The B_SESS_VLD_WAKEUP_EN bit 6 was added by a mistake in a previous
commit. This bit corresponds to B_SESS_END_WAKEUP_EN, which we don't use.
The B_VBUS_VLD_WAKEUP_EN doesn't exist at all and B_SESS_VLD_WAKEUP_EN
needs to be in place of it. We don't utilize B-sensors in the driver,
so it never was a problem, nevertheless let's correct the definition of
the bits.

usb: phy: tegra: Wait for VBUS wakeup status deassertion on suspend

2021-07-14T15:07:41+00:00

[ Upstream commit 6f8d39a8ef55efde414b6e574384acbce70c3119 ]

Some devices need an extra delay after losing VBUS, otherwise VBUS may
be detected as active at suspend time, preventing the PHY's suspension
by the VBUS detection sensor. This problem was found on Asus Transformer
TF700T (Tegra30) tablet device, where the USB PHY wakes up immediately
from suspend because VBUS sensor continues to detect VBUS as active after
disconnection. We need to poll the PHY's VBUS wakeup status until it's
deasserted before suspending PHY in order to fix this minor trouble.

usb: phy: tegra: Add delay after power up

2021-01-13T10:26:34+00:00

The PHY hardware needs the delay of 2ms after power up, otherwise initial
interrupt may be lost if USB controller is accessed before PHY is settled
down. Previously this issue was masked by implicit delays, but now it pops
up after squashing the older ehci-tegra driver into the ChipIdea driver.
