Re: [PATCH] SPI: spidev: Add DT compatible string for spidev driver.

but also to easily handle the case where a driver for that particular device is finally implemented, since we won't have to change the device tree in itself to reflect this. So I suggest you only add to the "real" compatible string instead of a generic one. Maxime [1] http://comments

[PATCH] spi: spi-gpio: fix compilation warning on 64 bits systems

[PATCH 1/2] spi: spi-gpio: Add checks for the dt properties

The bindings assumed that the gpios properties were always there, which made the NO_TX and NO_RX mode not usable from device tree. Add extra checks to make sure that the driver can work if either MOSI or MISO is not used. Signed-off-by: Maxime Ripard Cc: Mark Brown --- drivers/spi/spi-gpio.c

If you don't do it, the bus number will be a bogus value, possibly used for device file names in drivers like spidev. Signed-off-by: Maxime Ripard --- drivers/spi/spi-mxs.c |9 + 1 file changed, 9 insertions(+) diff --git a/drivers/spi/spi-mxs.c b/drivers/spi/spi-mxs.c

Re: [PATCH v4] spi: add Broadcom BCM63xx SPI controller driver

ility is arrange that the transfer happens and its complete() callback is issued. The two will normally happen later, after other transfers complete, and if the controller is idle it will need to be kickstarted. So we cannot do a synchronous wait here, this must be push
