PHY model is being used on omap5 platforms even if port mode is not OMAP_EHCI_PORT_MODE_PHY. So don't guess if PHY is required or not based on PHY mode. If PHY is provided in device tree, it must be required. So, if devm_usb_get_phy_by_phandle() gives us an error code other than -ENODEV (no PHY) then error out.

That makes the USB role switch support option visible and selectable for the user. The class driver is also moved to drivers/usb/roles/ directory. This will fix an issue that we have with the Intel USB role switch driver on systems that don't have USB Type-C connectors: Intel USB role switch driver depends on the USB role switch class as it should, but since there was no way for the user to enable the USB role switch class, there was also no way to select that driver. USB Type-C drivers select the USB role switch class which makes the Intel USB role switch driver available and therefore hides the problem. So in practice Intel USB role switch driver was depending on USB Type-C drivers.

2018-12-17tpm: add support for partial readsTadeusz Struk
Currently to read a response from the TPM device an application needs provide big enough buffer for the whole response and read it in one go. The application doesn't know how big the response it beforehand so it always needs to maintain a 4K buffer and read the max (4K). In case if the user of the TSS library doesn't provide big enough buffer the TCTI spec says that the library should set the required size and return TSS2_TCTI_RC_INSUFFICIENT_BUFFER error code so that the application could allocate a bigger buffer and call receive again. To make it possible in the TSS library, this requires being able to do partial reads from the driver. The library would read the 10 bytes header first to get the actual size of the response from the header, and then read the rest of the response. This patch adds support for partial reads, i.e. the user can read the response in one or multiple reads, until the whole response is consumed. The user can also read only part of the response and ignore the rest by issuing a new write to send a new command.

2018-12-17mmc: core: Cleanup BKOPS supportUlf Hansson
It's been ~6 years ago since we introduced the BKOPS support for eMMC cards. The current code is a bit messy and primarily that's because it prepares to support running BKOPS in an asynchronous mode. However, that mode has never been fully implemented/enabled. Instead BKOPS is always executed in synchronously, when the card has reported an urgent BKOPS level. For these reasons, let's make the code more readable by dropping the unused parts. Let's also rename mmc_start_bkops() to mmc_run_bkops(), as to make it more descriptive.

2018-12-17mmc: core: Use a minimum 1600ms timeout when enabling CACHE ctrlUlf Hansson
Some eMMCs from Micron have been reported to need ~800 ms timeout, while enabling the CACHE ctrl after running sudden power failure tests. The needed timeout is greater than what the card specifies as its generic CMD6 timeout, through the EXT_CSD register, hence the problem. Normally we would introduce a card quirk to extend the timeout for these specific Micron cards. However, due to the rather complicated debug process needed to find out the error, let's simply use a minimum timeout of 1600ms, the double of what has been reported, for all cards when enabling CACHE ctrl.
