2023-04-24tpm, tpm_tis: Request threaded interrupt handlerLino Sanfilippo
The TIS interrupt handler at least has to read and write the interrupt status register. In case of SPI both operations result in a call to tpm_tis_spi_transfer() which uses the bus_lock_mutex of the spi device and thus must only be called from a sleepable context. To ensure this request a threaded interrupt handler.

2023-04-24tpm, tpm: Implement usage counter for localityLino Sanfilippo
Implement a usage counter for the (default) locality used by the TPM TIS driver: Request the locality from the TPM if it has not been claimed yet, otherwise only increment the counter. Also release the locality if the counter is 0 otherwise only decrement the counter. Since in case of SPI the register accesses are locked by means of the SPI bus mutex use a sleepable lock (i.e. also a mutex) to ensure thread-safety of the counter which may be accessed by both a userspace thread and the interrupt handler. By doing this refactor the names of the amended functions to use a more appropriate prefix.

2023-04-24tpm, tpm_tis: do not check for the active locality in interrupt handlerLino Sanfilippo
After driver initialization tpm_tis_data->locality may only be modified in case of a LOCALITY CHANGE interrupt. In this case the interrupt handler iterates over all localities only to assign the active one to tpm_tis_data->locality. However this information is never used any more, so the assignment is not needed. Furthermore without the assignment tpm_tis_data->locality cannot change any more at driver runtime, and thus no protection against concurrent modification is required when the variable is read at other places. So remove this iteration entirely.

2023-04-24tpm, tpm_tis: Only handle supported interruptsLino Sanfilippo
According to the TPM Interface Specification (TIS) support for "stsValid" and "commandReady" interrupts is only optional. This has to be taken into account when handling the interrupts in functions like wait_for_tpm_stat(). To determine the supported interrupts use the capability query. Also adjust wait_for_tpm_stat() to only wait for interrupt reported status changes. After that process all the remaining status changes by polling the status register.

2023-04-24tpm, tpm_tis: Claim locality before writing interrupt registersLino Sanfilippo
In tpm_tis_probe_single_irq() interrupt registers TPM_INT_VECTOR, TPM_INT_STATUS and TPM_INT_ENABLE are modified to setup the interrupts. Currently these modifications are done without holding a locality thus they have no effect. Fix this by claiming the (default) locality before the registers are written. Since now tpm_tis_gen_interrupt() is called with the locality already claimed remove locality request and release from this function.

2023-04-24tpm, tpm_tis: Do not skip reset of original interrupt vectorLino Sanfilippo
If in tpm_tis_probe_irq_single() an error occurs after the original interrupt vector has been read, restore the interrupts before the error is returned. Since the caller does not check the error value, return -1 in any case that the TPM_CHIP_FLAG_IRQ flag is not set. Since the return value of function tpm_tis_gen_interrupt() is not longer used, make it a void function.

Both functions tpm_tis_probe_irq_single() and tpm_tis_probe_irq() may setup the interrupts and then return with an error. This case is indicated by a missing TPM_CHIP_FLAG_IRQ flag in chip->flags.

2023-04-24tpm, tpm_tis: Avoid cache incoherency in test for interruptsLino Sanfilippo
The interrupt handler that sets the boolean variable irq_tested may run on another CPU as the thread that checks irq_tested as part of the irq test in tpm_tis_send(). Since nothing guarantees cache coherency between CPUs for unsynchronized accesses to boolean variables the testing thread might not perceive the value change done in the interrupt handler. Avoid this issue by setting the bit TPM_TIS_IRQ_TESTED in the flags field of the tpm_tis_data struct and by accessing this field with the bit manipulating functions that provide cache coherency. Also convert all other existing sites to use the proper macros when accessing this bitfield.

This means that the last constant PMBUS_HAVE_IIN was not OR-ed with the other PM_BUS_HAVE_* constants for this page but it initialized the next element of the func array (which was not accessed from anywhere because of the number of pages). However, there is no need for setting PMBUS_HAVE_IIN in the 5Vsb page because this command does not seem to be paged.

ath9k_mci_update_wlan_channels() This partially reverts commit e161d4b60ae3a5356e07202e0bfedb5fad82c6aa. Turns out the channelmap variable is not actually read-only, it's modified through the MCI_GPM_CLR_CHANNEL_BIT() macro further down in the function, so making it read-only causes page faults when that code is hit.

2023-04-20PCI: Restrict device disabled status check to DTRob Herring
Commit 6fffbc7ae137 ("PCI: Honor firmware's device disabled status") checked the firmware device status for both DT and ACPI devices. That caused a regression in some ACPI systems. The exact reason isn't clear. It's possibly a firmware bug. For now, at least, refactor the check to be for DT based systems only. Note that the original implementation leaked a refcount which is now correctly handled.
