<content type='text'>
commit baaef0a274cfb75f9b50eab3ef93205e604f662c upstream.

There are two variables that indicate the interrupt type to be used
in the next test execution, "irq_type" as global and "test-&gt;irq_type".

The global is referenced from pci_endpoint_test_get_irq() to preserve
the current type for ioctl(PCITEST_GET_IRQTYPE).

The type set in this function isn't reflected in the global "irq_type",
so ioctl(PCITEST_GET_IRQTYPE) returns the previous type.

As a result, the wrong type is displayed in old version of "pcitest"
as follows:

  - Result of running "pcitest -i 0"

      SET IRQ TYPE TO LEGACY:         OKAY

  - Result of running "pcitest -I"

      GET IRQ TYPE:           MSI

Whereas running the new version of "pcitest" in kselftest results in an
error as follows:

  #  RUN           pci_ep_basic.LEGACY_IRQ_TEST ...
  # pci_endpoint_test.c:104:LEGACY_IRQ_TEST:Expected 0 (0) == ret (1)
  # pci_endpoint_test.c:104:LEGACY_IRQ_TEST:Can't get Legacy IRQ type

Fix this issue by propagating the current type to the global "irq_type".

commit 919d14603dab6a9cf03ebbeb2cfa556df48737c8 upstream.

There are two variables that indicate the interrupt type to be used
in the next test execution, global "irq_type" and "test-&gt;irq_type".

The former is referenced from pci_endpoint_test_get_irq() to preserve
the current type for ioctl(PCITEST_GET_IRQTYPE).

In the pci_endpoint_test_request_irq(), since this global variable
is referenced when an error occurs, the unintended error message is
displayed.

For example, after running "pcitest -i 2", the following message
shows "MSI 3" even if the current IRQ type becomes "MSI-X":

  pci-endpoint-test 0000:01:00.0: Failed to request IRQ 30 for MSI 3
  SET IRQ TYPE TO MSI-X:          NOT OKAY

Fix this issue by using "test-&gt;irq_type" instead of global "irq_type".

commit f6cb7828c8e17520d4f5afb416515d3fae1af9a9 upstream.

After devm_request_irq() fails with error in pci_endpoint_test_request_irq(),
the pci_endpoint_test_free_irq_vectors() is called assuming that all IRQs
have been released.

However, some requested IRQs remain unreleased, so there are still
/proc/irq/* entries remaining, and this results in WARN() with the
following message:

  remove_proc_entry: removing non-empty directory 'irq/30', leaking at least 'pci-endpoint-test.0'
  WARNING: CPU: 0 PID: 202 at fs/proc/generic.c:719 remove_proc_entry +0x190/0x19c

To solve this issue, set the number of remaining IRQs to test-&gt;num_irqs,
and release IRQs in advance by calling pci_endpoint_test_release_irq().

commit 038ef0754aae76f79b147b8867f9250e6a976872 upstream.

The dev_id value in the GPIO lookup table must match to
the device instance name, which in this case is combined
of name and platform device ID, i.e. "spi_gpio.1". But
the table assumed that there was no platform device ID
defined, which is wrong. Fix the dev_id value accordingly.

This reverts commit 235b630eda072d7e7b102ab346d6b8a2c028a772.

This commit was found responsible for issues with SD card recognition,
as users had to re-insert their cards in the readers and wait for a
while. As for some people the SD card was involved in the boot process
it also caused boot failures.

commit 6ca4ea1f88a06a04ed7b2c9c6bf9f00833b68214 upstream.

For registered  buffers, fastrpc driver sends the buffer information
to remote subsystem. There is a problem with current implementation
where the page address is being sent with an offset leading to
improper buffer address on DSP. This is leads to functional failures
as DSP expects base address in page information and extracts offset
information from remote arguments. Mask the offset and pass the base
page address to DSP.

This issue is observed is a corner case when some buffer which is registered
with fastrpc framework is passed with some offset by user and then the DSP
implementation tried to read the data. As DSP expects base address and takes
care of offsetting with remote arguments, passing an offsetted address will
result in some unexpected data read in DSP.

All generic usecases usually pass the buffer as it is hence is problem is
not usually observed. If someone tries to pass offsetted buffer and then
tries to compare data at HLOS and DSP end, then the ambiguity will be observed.

This commit reintroduces interrupt-based card detection previously
used in the rts5139 driver. This functionality was removed in commit
00d8521dcd23 ("staging: remove rts5139 driver code").

Reintroducing this mechanism fixes presence detection for certain card
readers, which with the current driver, will taken approximately 20
seconds to enter S3 as `mmc_rescan` has to be frozen.

[ Upstream commit 7738a7ab9d12c5371ed97114ee2132d4512e9fd5 ]

Add a quirk similar to eeprom_93xx46 to add an extra clock cycle before
reading data from the EEPROM.

The 93Cx6 family of EEPROMs output a "dummy 0 bit" between the writing
of the op-code/address from the host to the EEPROM and the reading of
the actual data from the EEPROM.

More info can be found on page 6 of the AT93C46 datasheet (linked below).
Similar notes are found in other 93xx6 datasheets.

In summary the read operation for a 93Cx6 EEPROM is:
Write to EEPROM:	110[A5-A0]	(9 bits)
Read from EEPROM:	0[D15-D0]	(17 bits)

Where:
	110 is the start bit and READ OpCode
	[A5-A0] is the address to read from
	0 is a "dummy bit" preceding the actual data
	[D15-D0] is the actual data.

Looking at the READ timing diagrams in the 93Cx6 datasheets the dummy
bit should be clocked out on the last address bit clock cycle meaning it
should be discarded naturally.

However, depending on the hardware configuration sometimes this dummy
bit is not discarded. This is the case with Exar PCI UARTs which require
an extra clock cycle between sending the address and reading the data.
