1 How to port a SPI driver to driver model
5 exynos SPI driver to driver model (DM) and the example code is based
11 Before driver model, SPI drivers have their own private structure which
13 exists, but now it is 'per-child data' for the SPI bus. Each child of the
14 SPI bus is a SPI slave. The information that was stored in the
16 SPI bus.
26 SPI's buses private data.
39 1. Enable driver mode for SPI and SPI flash
163 empty SPI driver. You still have empty methods in your driver, but we will

357 This should set up clocks so that the SPI bus is running at the right
421 This should adjust the SPI mode (polarity, etc.). Again this code probably

597 20. A little note about SPI uclass features:
599 The SPI uclass keeps some information about each device 'dev' on the bus:
611 There are also some SPI uclass methods that get called behind the scenes:
628 The above housekeeping makes it easier to write your SPI driver.
