Simon Glass	1e6ca1a6ad	dm: core: Add an implementation of regmap_init_mem_platdata() ... 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.

Simon Glass	a951431e82	dm: core: Move regmap allocation into a separate function ... We plan to add a new way of creating a regmap for of-platdata. Move the allocation code into a separate function so that it can be shared. Signed-off-by: Simon Glass <sjg@chromium.org>	2016-07-14 20:40:24 -06:00
Simon Glass	3b2a29e097	dm: regmap: Add a dummy implementation for of-platdata ... Add a placeholder for now so that this code will compile. It currently does nothing. Signed-off-by: Simon Glass <sjg@chromium.org>	2016-07-14 20:40:24 -06:00
Simon Glass	6f98b7504f	dm: Add support for register maps (regmap) ... 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>	2015-07-21 17:39:23 -06:00
