2018-02-14spi: spi-gpio: Augment device tree bindingsLinus Walleij1-6/+18
After we augmented the core to handle "gpio-sck"/"sck-gpios", "gpio-mosi"/"mosi-gpios", "gpio-miso"/"miso-gpios" alike, deprecate the old binding and put the strict modern and recommended binding practice into place as the default for GPIO-based SPI. This reflects the similar change in I2C: commit 7d29f509d2cf ("dt-bindings: i2c: i2c-gpio: Add support for named gpios") Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>

On Armada 7K/8K we need to explicitly enable the bus clock. The bus clock is optional because not all the SoCs need them but at least for Armada 7K/8K it is actually mandatory.

2017-03-20spi: pl022: remove nonexistent properties from DT binding exampleAntonio Borneo1-3/+0
The properties "pl022,hierarchy" and "pl022,slave-tx-disable" were initially proposed till patch V4 [1] but then discarded in V5 [2] when the patch set was taken over by another developer, as explained in patch history in [3]. The above properties never landed in mainline code but were then listed in the binding example by a following commit dc715452e914 ("spi: pl022: use generic DMA slave configuration if possible") and later on they were copy-paste in some board's DT. Remove the nonexistent properties from the example. Also remove a spaces-only line at the end of the file.
