2022-07-24i2c: cadence: Support PEC for SMBus block readLars-Peter Clausen
SMBus packet error checking (PEC) is implemented by appending one additional byte of checksum data at the end of the message. This provides additional protection and allows to detect data corruption on the I2C bus. SMBus block reads support variable length reads. The first byte in the read message is the number of available data bytes. The combination of PEC and block read is currently not supported by the Cadence I2C driver. * When PEC is enabled the maximum transfer length for block reads increases from 33 to 34 bytes. * The I2C core smbus emulation layer relies on the driver updating the `i2c_msg` `len` field with the number of received bytes. The updated length is used when checking the PEC. Add support to the Cadence I2C driver for handling SMBus block reads with PEC. To determine the maximum transfer length uses the initial `len` value of the `i2c_msg`. When PEC is enabled this will be 2, when it is disabled it will be 1. Once a read transfer is done also increment the `len` field by the amount of received data bytes. This change has been tested with a UCM90320 PMBus power monitor, which requires block reads to access certain data fields, but also has PEC enabled by default.

2022-07-22PCI: Extend isolated function probing to s390Niklas Schnelle
Like the jailhouse hypervisor, s390's PCI architecture allows passing isolated PCI functions to a guest OS instance. As of now this is was not utilized even with multi-function support as the s390 PCI code makes sure that only virtual PCI busses including a function with devfn 0 are presented to the PCI subsystem. A subsequent change will remove this restriction. Allow probing such functions by replacing the existing check for jailhouse_paravirt() with a new hypervisor_isolated_pci_functions() helper.

2022-07-22PCI: Move jailhouse's isolated function handling to pci_scan_slot()Niklas Schnelle
The special case of the jailhouse hypervisor passing through individual PCI functions handles scanning for PCI functions even if function 0 does not exist. Previously this was done with an extra loop duplicating the one in pci_scan_slot(). By incorporating the check for jailhouse_paravirt() into pci_scan_slot() we can instead do this as part of the normal slot scan. Note that with the assignment of dev->multifunction gated by fn > 0 we set dev->multifunction unconditionally for all functions if function 0 is missing just as in the existing jailhouse loop. The only functional change is that we now call pcie_aspm_init_link_state() for these functions, but this already happened if function 0 was passed through and should not be a problem.
