* spi: pl022: Specify 'num-cs' property as required in devicetree bindingEzequiel Garcia2015-07-21
| | | | | | | | | | | | | | | | commit ea6055c46eda1e19e02209814955e13f334bbe1b upstream. Since commit 39a6ac11df65 ("spi/pl022: Devicetree support w/o platform data") the 'num-cs' parameter cannot be passed through platform data when probing with devicetree. Instead, it's a required devicetree property. Fix the binding documentation so the property is properly specified.

| | * | | spi/rockchip: Add device tree property to configure Rx Sample DelayJulius Werner2015-03-26
| | |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have found that we can sometimes see read failures on boards with high-capacitance SPI lines. It seems that the controller samples the Rx data line too early, and its register interface has an "Rx Sample Delay" setting to fine-tune against this issue. This patch adds a new optional device tree entry that can configure this delay in terms of nanoseconds. The kernel will calculate the best-fitting amount of parent clock ticks to program the controller with based on that.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds DMA capabilities to the spi-qup driver. If DMA channels are present, the QUP will use DMA instead of block mode for transfers to/from SPI peripherals for transactions larger than the length of a block.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the CONTINUE bit is set, the interrupt status we are polling to identify if a transaction has finished can be sporadic. Even though the transfer has finished, the interrupt status may erroneously indicate that there is still data in the FIFO. This behaviour causes random timeouts in large PIO transfers. Instead of using the CONTINUE bit to control the CS lines, use the SPI core's CS GPIO handling. Also, now that the CONTINUE bit is not being used, we can poll for the ALLDONE interrupt to indicate transfer completion.

Specifically the Serial Baud Rate Pre-selection bits in the SPI Interface Configuration Register now also use bits 6 and 7 as well. Modify the baud rate calculation to handle these differences for the Armada case. Potentially a baud rate can be setup using a number of different pre-scalar and scalar combinations. This code tries all possible pre-scalar divisors (8 in total) to try and find the most accurate set. This change introduces (and documents) a new device tree compatible device name "armada-370-spi" to support this.

| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently driver supports only configuration of GPIO CS through platform data. This patch enhances the driver to configure GPIO CS through DT. Also update the DT binding documentation to reflect the availability of cs-gpios.

* / / spi: qup: Remove chip select functionAndy Gross2014-06-22
|/ / | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the chip select function. Chip select should instead be supported using GPIOs, defining the DT entry "cs-gpios", and letting the SPI core assert/deassert the chip select as it sees fit. The chip select control inside the controller is buggy. It is supposed to automatically assert the chip select based on the activity in the controller, but it is buggy and doesn't work at all. So instead we elect to use GPIOs. Signed-off-by: Andy Gross <agross@codeaurora.org> Signed-off-by: Mark Brown <broonie@linaro.org>
