phy: stm32: fix an error code in probe

2022-10-17T05:25:26Z

If "index > usbphyc->nphys" is true then this returns success but it should return -EINVAL.

phy: stm32: fix error return in stm32_usbphyc_phy_init

2022-07-15T11:34:25Z

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: stm32: adopt dev_err_probe for regulators

phy: stm32: add phy tuning support

2021-10-26T11:06:22Z

It can be necessary to adjust the phys settings to compensate parasitics. This patch adds support of new optional properties to configure the tune interface of the phys of stm32-usbphyc. Properties are optional, that's why each property is skipped if not found (-EINVAL). Phy tuning is restored on resume because if deep low power state is achieved, phy tuning configuration is reset.
