2016-07-15dm: core: Add an implementation of regmap_init_mem_platdata()Simon Glass
Add an implementation of this function which mirrors the functions of the automatic device-tree implementation. This can be used with of-platdata to create regmaps. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-07-15dm: regmap: Add a dummy implementation for of-platdataSimon Glass
Add a placeholder for now so that this code will compile. It currently does nothing. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-07-21dm: Add support for register maps (regmap)Simon Glass
Add a simple implementaton of register maps, supporting only direct I/O for now. This can be enhanced later to support buses which have registers, such as I2C, SPI and PCI. It allows drivers which can operate with multiple buses to avoid dealing with the particulars of register access on that bus. Signed-off-by: Simon Glass <sjg@chromium.org>
