In current design of the PPS APDO selection, TCPM power supply only accepts the requested voltage which is inside the range of the selected PPS profile. To extend the flexibility and usability, remove the checks about the voltage range in current profile. And try to search all PPS APDOs of the Source that fit the requested voltage. Also remove some redundant checks in tcpm_pd_build_pps_request.

2023-07-30usb: misc: onboard-hub: add support for Cypress HX3 USB 3.0 familyBenjamin Bara2-0/+10
The HX3 comes in different variants (up to 4 USB 3.0 ports; multi-TT), e.g. CYUSB330x/CYUSB331x/CYUSB332x/CYUSB230x. It operates with two different power supplies: 1V2 and 3V3. Add the support for this hub, for controlling the reset pin and the power supplies. Reset time is extracted from data sheet, page 24: "The RESETN pin can be tied to VDD_IO through an external resistor and to ground (GND) through an external capacitor (minimum 5 ms time constant)." V_IH min is given at 0.7 * 3V3 (page 34), therefore use 10ms. Also add USB PIDs for the USB 2.0 and USB 3.0 root hub.

2023-07-27usb: dwc3: pci: skip BYT GPIO lookup table for hardwired phyGratian Crisan1-2/+4
Hardware based on the Bay Trail / BYT SoCs require an external ULPI phy for USB device-mode. The phy chip usually has its 'reset' and 'chip select' lines connected to GPIOs described by ACPI fwnodes in the DSDT table. Because of hardware with missing ACPI resources for the 'reset' and 'chip select' GPIOs commit 5741022cbdf3 ("usb: dwc3: pci: Add GPIO lookup table on platforms without ACPI GPIO resources") introduced a fallback gpiod_lookup_table with hard-coded mappings for Bay Trail devices. However there are existing Bay Trail based devices, like the National Instruments cRIO-903x series, where the phy chip has its 'reset' and 'chip-select' lines always asserted in hardware via resistor pull-ups. On this hardware the phy chip is always enabled and the ACPI dsdt table is missing information not only for the 'chip-select' and 'reset' lines but also for the BYT GPIO controller itself "INT33FC". With the introduction of the gpiod_lookup_table initializing the USB device-mode on these hardware now errors out. The error comes from the gpiod_get_optional() calls in dwc3_pci_quirks() which will now return an -ENOENT error due to the missing ACPI entry for the INT33FC gpio controller used in the aforementioned table. This hardware used to work before because gpiod_get_optional() will return NULL instead of -ENOENT if no GPIO has been assigned to the requested function. The dwc3_pci_quirks() code for setting the 'cs' and 'reset' GPIOs was then skipped (due to the NULL return). This is the correct behavior in cases where the phy chip is hardwired and there are no GPIOs to control. Since the gpiod_lookup_table relies on the presence of INT33FC fwnode in ACPI tables only add the table if we know the entry for the INT33FC gpio controller is present. This allows Bay Trail based devices with hardwired dwc3 ULPI phys to continue working.
