dm: core: Add warnings to private / platform setters

2021-03-26T04:03:09+00:00

Add a warning to each of these functions so that people do not attempt to use them outside driver model. Signed-off-by: Simon Glass Signed-off-by: Simon Glass

dm: core: Add macros to access the new linker lists

2021-03-22T06:23:28+00:00

Add macros which work with instantiated devices and uclasses, as created at build time by dtoc. Include variants that can be used in data structures. These are mostly used by dtoc but it is worth documenting them fully for the occasional case where they might come up in user code. Signed-off-by: Simon Glass Signed-off-by: Simon Glass

dm: core: Add function to access uclass priv

2021-01-05T19:24:40+00:00

Add functions so this information is not accessed directly. This will be needed for of-platdata which stores it in a different place. Signed-off-by: Simon Glass

dm: core: Update uclass_find_next_free_req_seq() for new scheme

2020-12-19T03:32:21+00:00

This function current deals with req_seq which is deprecated. Update it to use the new sequence numbers, putting them above existing aliases. Rename the function to make this clear. Signed-off-by: Simon Glass

dm: Drop the unused arg in uclass_find_device_by_seq()

2020-12-19T03:32:21+00:00

Now that there is only one sequence number (rather than both requested and assigned ones) we can simplify this function. Also update its caller to simplify the logic. Signed-off-by: Simon Glass

dm: core: Update uclass_find_next_free_req_seq() args

2020-12-19T03:32:21+00:00

At present this is passed a uclass ID and it has to do a lookup. The callers all have the uclass pointer, except for the I2C uclass where the code will soon be deleted. Update the argument to a uclass * instead of an ID since it is more efficient. Signed-off-by: Simon Glass

dm: core: Correct the return value for uclass_find_first_device()

2019-10-08T05:57:38+00:00

This function returns -ENODEV when there is no device. This is inconsistent with other functions, such as uclass_find_next_device(), which returns 0. Update it and tidy up the incorrect '-1' values in the comments. Signed-off-by: Simon Glass Reviewed-by: Bin Meng Tested-by: Bin Meng

dm: device: Allow using uclass_find_device_by_seq() without OF_CONTROL

2018-12-10T05:05:32+00:00

If OF_CONTROL is not enabled and DM_SEQ_ALIAS is enabled, we must assign an alias (requested sequence number) to devices that belongs to a class with the DM_UC_FLAG_SEQ_ALIAS flag. Otherwise uclass_find_device_by_seq() cannot be used to get/probe a device. In particular i2c_get_chip_for_busnum() cannot be used.

dm: core: Export uclass_find_device_by_phandle()

2018-11-29T16:30:05+00:00

This function may be useful to code outside of the code driver-model implementation. Export it and add a test. Signed-off-by: Simon Glass

uclass: Add dev_get_uclass_index() to get the uclass/index of a device

2018-08-21T14:21:37+00:00

This function is the reciprocal of uclass_find_device(). It will be used to print the index information in dm tree dump. Signed-off-by: Jean-Jacques Hiblot
