* | dm: core: Add device checking to syscon_get_regmap() | Simon Glass | 2015-07-21 | -2/+5 |
| | | | | | | | | | | 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> | |||
* | dm: Add support for generic system controllers (syscon) | Simon Glass | 2015-07-21 | -0/+73 |
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.
