Re: SPI driver development

Hi Jiri,

One thing is common over all drivers is how it iterates through the r/w
buffers (drivers/spi/spi_context.h) but rest depends on hardware and
whether or not you use a HAL to access it (nrfx, stm32 are doing it for
instance).

Up to you to decide if you want to use a HAL (from Atmel's ASF) or not
then.

Hi,
I would like to try develop SPI driver for SAME70. However by looking
to ./drivers/spi/ it seems that every driver is implemented by its
own way (some needs workarounds in dts.fixup). Is there some spi
driver which I can take as reference? Im quite new to this so any
help is appreciate.

Best regards,
Jiri
