phy: usb: Fix misuse of IS_ENABLED

2021-06-16T10:01:43+00:00

commit 7c2fc79250cafa1a29befeb60163028ec4720814 upstream. While IS_ENABLED() is perfectly fine for CONFIG_* symbols, it is not for other symbols such as __BIG_ENDIAN that is provided directly by the compiler. Switch to use CONFIG_CPU_BIG_ENDIAN instead of __BIG_ENDIAN.

phy: usb: Fix incorrect clearing of tca_drv_sel bit in SETUP reg for 7211

2020-10-28T16:10:56+00:00

The 7211a0 has a tca_drv_sel bit in the USB SETUP register that should never be enabled. This feature is only used if there is a USB Type-C PHY, and the 7211 does not have one. If the bit is enabled, the VBUS signal will never be asserted. In the 7211a0, the bit was incorrectly defaulted to on so the driver had to clear the bit. In the 7211c0 the state was inverted so the driver should no longer clear the bit. This hasn't been a problem because all current 7211 boards don't use the VBUS signal, but there are some future customer boards that may use it.

drivers: phy: sr-usb: do not use internal fsm for USB2 phy init

2020-05-18T14:00:56+00:00

During different reboot cycles, USB PHY PLL may not always lock during initialization and therefore can cause USB to be not usable. Hence do not use internal FSM programming sequence for the USB PHY initialization.
