2019-11-18spi: st-ssc4: add missed pm_runtime_disableChuhong Yuan1-0/+3
The driver forgets to call pm_runtime_disable in probe failure and remove. Add the missed calls to fix it. Signed-off-by: Chuhong Yuan <hslester96@gmail.com> Link: https://lore.kernel.org/r/20191118024848.21645-1-hslester96@gmail.com Signed-off-by: Mark Brown <broonie@kernel.org>
2019-09-04spi: st-ssc4: use devm_platform_ioremap_resource() to simplify codeYueHaibing1-3/+1
Use devm_platform_ioremap_resource() to simplify the code a bit. This is detected by coccinelle.

Remove stray single spaces after a leading hard-tab. Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-09-14spi: st-ssc4: Fix misuse of devm_gpio_request/devm_gpio_free APIsAxel Lin1-8/+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.

2016-07-12spi: st-ssc4: Remove 'no clocking' hackLee Jones1-31/+5
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>

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>
2015-01-14spi: st-ssc4: Remove duplicate code to test unsupported mode bitsAxel Lin1-6/+0
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>
