* spi: st-ssc4: whitespace cleanupChris Packham2017-05-261-19/+19

* spi: st-ssc4: Fix misuse of devm_gpio_request/devm_gpio_free APIsAxel Lin2016-09-141-8/+11
| | | | | | | | | | devm_* API is supposed to be used only in probe function call. The resource is allocated at 'probe' and free automatically at 'remove'. Usage of devm_* functions outside probe sometimes leads to resource leak. Thus avoid using devm_* APIs in .setup/.cleanup callbacks.

* spi: st-ssc4: Remove 'no clocking' hackLee Jones2016-07-121-31/+5Star
| | | | | | | | Due to the newly upstreamed 'critical clocks' API we can now safely handle clocking in the SPI and I2C drivers without fear of catastrophically crippling the running platform. Signed-off-by: Lee Jones <lee.jones@linaro.org>

* spi: constify of_device_id arrayFabian Frederick2015-03-171-1/+1
| | | | | | | | of_device_id is always used as const. (See driver.of_match_table and open firmware functions) Signed-off-by: Fabian Frederick <fabf@skynet.be> Signed-off-by: Mark Brown <broonie@kernel.org>
* spi: st-ssc4: Remove duplicate code to test unsupported mode bitsAxel Lin2015-01-141-6/+0Star
| | | | | | | | spi_setup() will test unsupported mode bits before calling spi->master->setup. Thus remove duplicate code to test unsupported mode bits in spi_st_setup(). Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@kernel.org>
