spi: loopback-test: mark rx_ranges_cmp() static

2016-09-01T19:54:54+00:00

We get 1 warning when building kernel with W=1:
drivers/spi/spi-loopback-test.c:408:5: warning: no previous prototype for 'rx_ranges_cmp' [-Wmissing-prototypes]

In fact, this function is only used in the file in which it is
declared and don't need a declaration, but can be made static.
So this patch marks it 'static'.

spi: fix counting in spi-loopback-test code

2016-01-15T18:13:53+00:00

These variables are always used uninitialized:

drivers/spi/spi-loopback-test.c: In function 'spi_test_run_iter':
drivers/spi/spi-loopback-test.c:768:17: warning: 'rx_count' may be used uninitialized in this function [-Wmaybe-uninitialized]
drivers/spi/spi-loopback-test.c:762:17: warning: 'tx_count' may be used uninitialized in this function [-Wmaybe-uninitialized]

Adding an explicit initialization seems to be the only
workable solution here, to make the code behave correctly
and build without warning.

spi: loopback: fix typo in MODULE_PARM_DESC

2016-01-08T12:53:35+00:00

There should be an 's' on "dump_message" so it matches the module_param.

spi: loopback-test: spi_check_rx_ranges can get always done

2016-01-05T19:12:47+00:00

The spi_check_rx_ranges can always get executed independent of
if we have a real loopback situation.

spi: loopback-test: rename method spi_test_fill_tx to spi_test_fill_pattern

2016-01-05T19:05:23+00:00

Rename method spi_test_fill_tx to spi_test_fill_pattern
to better describe what it does.

spi: loopback-test: write rx pattern also when running without tx_buf

2016-01-05T19:05:23+00:00

Currently the rx_buf does not get set with the
SPI_TEST_PATTERN_UNWRITTEN when tx_buf == NULL in the transfer.

Reorder code so that it gets done also under this specific condition.

spi: loopback: match configuration of test to description

2015-12-13T20:10:14+00:00

The test "two tx+rx transfers - alter second" actually modifies
the first not the second transfer, which - in conjunction with
testing the read data - results also in overwriting data read
earlier.

spi: add loopback test driver to allow for spi_master regression tests

2015-12-12T23:05:18+00:00

This driver is submitting lots of distinct spi-messages messages
with all kinds of alignments and length pattern.
Also distinct kinds of transfer pattern tests are implemented
(rx, tx, rx/tx, tx+tx, tx+rx,...)

Right now on a raspberry pi 752 distinct spi_messages are executed
in 13 different scenarios.

Configuration of additional test-pattern is easy, so that when
new bugs in drivers get detected the relevant transfer pattern can
also get added to the test framework, so that such situations are
detected in other drivers as well.

The idea behind this driver is to make it possible to also detect
regressions in spi_master implementations when changes occur.
Potentially these tests could get executed automatically in a
test-server-farm.
