2017-09-11dm: core: Add ofnode_for_each_subnode()Simon Glass
Add a convenience macro to iterate over subnodes of a node. Make use of this where appropriate in the code. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-06-01dm: pmic: Convert uclass to livetreeSimon Glass
Update the pmic uclass and all pmics to support a live device tree. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-02-08dm: core: Replace of_offset with accessorSimon Glass
At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

2016-01-21dm: power: Tidy up debugging output and return valuesSimon Glass
The currect PMIC debugging is a little confusing. Adjust it so that it is clear whether the operation succeeded or failed. Also, avoid creating a new error return value when a perfectly good one is already available. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21dm: power: Allow regulators to be omitted from SPLSimon Glass
For some boards the pmic interface is useful but the regulator interface (which comes with it) is too large. Allow them to be separated such that SPL can decide which it needs. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-08-05dm: pmic: Correct the pmic_reg_write() implementationSimon Glass
This should write the register, not read it. Fix this bug. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Przemyslaw Marczak <p.marczak@samsung.com>
2015-07-21power: pmic: Use trailing_strtol() instead of a local functionSimon Glass
Use the common function to obtain the number from the end of the string, instead of a local function. Also tweak the position of a debug() statement.

2015-07-21dm: pmic: Add functions to adjust PMIC registersSimon Glass
It is a common requirement to update some PMIC registers. Provide some simple convenience functions to do this. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Przemyslaw Marczak <p.marczak@samsung.com> Acked-by: Przemyslaw Marczak <p.marczak@samsung.com>
2015-07-21dm: power: Avoid case-insensitve match for child namesSimon Glass
This is not user input (i.e. from the command line). It should be possible to get the case correct and avoid the case-insensitive match. This will help avoid sloppy device tree setups.

2015-05-14dm: pmic: code cleanup of PMIC uclass driverPrzemyslaw Marczak
The cleanup includes: - pmic.h - fix mistakes in a few comments - pmic operations: value 'reg_count' - redefine as function call - fix function name: pmic_bind_childs() -> pmic_bind_children() - pmic_bind_children: change the 'while' loop with the 'for' - add implementation of pmic_reg_count() method - pmic_bind_children() - update function call name - Kconfig: add new line at the end of file - Update MAX77686 driver code Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Acked-by: Simon Glass <sjg@chromium.org> Tested on sandbox: Tested-by: Simon Glass <sjg@chromium.org>
2015-05-14dm: pmic: add implementation of driver model pmic uclassPrzemyslaw Marczak
This commit introduces the PMIC uclass implementation. It allows providing the basic I/O interface for PMIC devices. For the multi-function PMIC devices, this can be used as I/O parent device, for each IC's interface. Then, each PMIC particular function can be provided by the child device's operations, and the child devices will use its parent for read/write by the common API. Core files: - 'include/power/pmic.h' - 'drivers/power/pmic/pmic-uclass.c' The old pmic framework is still kept and is independent. For more detailed informations, please look into the header file. Changes: - new uclass-id: UCLASS_PMIC - new config: CONFIG_DM_PMIC Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Acked-by: Simon Glass <sjg@chromium.org>
