Simon Glass	ac94b7bcbe	dm: syscon: Allow finding devices by driver data ... We have a way to find a regmap by its syscon driver data value. Add the same for syscon itself. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>	9 years ago
Simon Glass	9f4629be8a	dm: core: Add device checking to syscon_get_regmap() ... This function can only handle a syscon device. It is possible that someone will make a mistake, so add a check for this. Also we should return -ENODEV when a device cannot be found, so update the syscon_get_regmap_by_driver_data() to follow this convention. Signed-off-by: Simon Glass <sjg@chromium.org>	10 years ago
Simon Glass	5725128507	dm: Add support for generic system controllers (syscon) ... Many SoCs have a number of system controllers which are dealt with as a group by a single driver. It is a pain to have to add lots of compatible strings and/or separate drivers for each. Instead we can identify the controllers by a number and request the address of the one we want. Add a simple implementation of this which can be used by SoC driver code. Signed-off-by: Simon Glass <sjg@chromium.org>	10 years ago
