spi: spi-loopback-test: use new `delay` field

2019-10-15T10:45:19Z

This change replaces the use of the `delay_usecs` field with the new `delay` field. The code/test still uses micro-seconds, but they are now configured and used via the `struct spi_delay` format of the `delay` field.

spi: loopback-test: implement testing with no CS

2017-07-26T12:08:56Z

To run spi-loopback-tests on HW without modifications, we need to disable Chip Select. This should avoid surprising side effects for SPI devices by testing patterns. Signed-off-by: Oleksij Rempel Signed-off-by: Mark Brown

spi: loopback-test: make several module parameters static

2017-07-18T13:10:01Z

Several module parameters are local to the source, so make them static. Cleans up several sparse warnings such as: "symbol 'loop_req' was not declared. Should it be static?" Signed-off-by: Colin Ian King Signed-off-by: Mark Brown

spi: loopback-test: provide loop_req option.

2017-07-17T14:27:26Z

Provide a module parameter to request internal loop by the SPI master controller. This should make loop testing easier without extra HW modification. For test automation a logic analyzer is recommended for host controller-independent verification. An example test rig configuration and procedure: i.MX6S RIoRBoard Logic Analyzer ----------------------------------------- (J13 4) GND ------------- GND (J13 6) CSPI3-CLK ------> PIN 3 (J13 8) CSPI3-MOSI <----- PIN 2 ^ - internal loop configured by SPI_LOOP | or can be user external jamper. (J13 10) CSPI3-MISO -----> PIN 1 grab some data and decode it: sigrok-cli -d fx2lafw --time 160000 --config samplerate=10m \ --channels 0-2 -o dump.sr sigrok-cli -i dump.sr -P spi:mosi=1:clk=2 > result_for_regression_tests Signed-off-by: Oleksij Rempel Signed-off-by: Mark Brown

spi: loopback-test: fix potential integer overflow on multiple

2017-03-20T16:11:39Z

A multiplication of 8U * xfer-len with the type of a 32 bit unsigned int is evaluated using 32 bit arithmetic and then used in a context that expects an expression of type unsigned long long (64 bits). Avoid any potential overflow by casting BITS_PER_BYTE to unsigned long long.
