reset: add exported __reset_control_get, return NULL if optional

2017-04-04T15:36:10Z

Rename the internal __reset_control_get/put functions to __reset_control_get/put_internal and add an exported __reset_control_get equivalent to __of_reset_control_get that takes a struct device parameter. This avoids the confusing call to __of_reset_control_get in the non-DT case and fixes the devm_reset_control_get_optional function to return NULL if RESET_CONTROLLER is enabled but dev->of_node == NULL.

reset: fix optional reset_control_get stubs to return NULL

2017-03-21T17:19:43Z

When RESET_CONTROLLER is not enabled, the optional reset_control_get stubs should now also return NULL. Since it is now valid for reset_control_assert/deassert/reset/status/put to be called unconditionally, with NULL as an argument for optional resets, the stubs are not allowed to warn anymore.

reset: make optional functions really optional

2017-01-20T09:36:15Z

The *_get_optional_* functions weren't really optional so this patch makes them really optional. These *_get_optional_* functions will now return NULL instead of an error if no matching reset phandle is found in the DT, and all the reset_control_* functions now accept NULL rstc pointers.

reset: Change shared flag from int to bool

2017-01-20T09:36:14Z

Since the new parameter being added is going to be a bool this patch changes the shared flag from int to bool to match the new parameter. Signed-off-by: Ramiro Oliveira Signed-off-by: Philipp Zabel

reset: Supply _shared variant calls when using _optional APIs

2016-06-29T19:24:53Z

Consumers need to be able to specify whether they are requesting an 'exclusive' or 'shared' reset line no matter which API (of_*, devm_*, etc) they are using. This change allows users of the optional_* API in particular to specify that their request is for a 'shared' line. Signed-off-by: Lee Jones Signed-off-by: Philipp Zabel

reset: Ensure drivers are explicit when requesting reset lines

2016-06-29T19:24:52Z

Phasing out generic reset line requests enables us to make some better decisions on when and how to (de)assert said lines. If an 'exclusive' line is requested, we know a device *requires* a reset and that it's preferable to act upon a request right away. However, if a 'shared' reset line is requested, we can reasonably assume sure that placing a device into reset isn't a hard requirement, but probably a measure to save power and is thus able to cope with not being asserted if another device is still in use. In order allow gentle adoption and not to forcing all consumers to move to the API immediately, causing administration headache between subsystems, this patch adds some temporary stand-in shim-calls. This will ease the burden at merge time and allow subsystems to migrate over to the new API in a more realistic time-frame. Signed-off-by: Lee Jones Signed-off-by: Philipp Zabel

reset: Reorder inline reset_control_get*() wrappers

2016-06-29T19:24:52Z

We're about to split the current API into two, where consumers will be forced to be explicit when requesting reset lines. The choice will be to either the call the *_exclusive or *_shared variant depending on whether they can actually tolorate not being asserted when that request is made. The new API will look like this once reorded and complete: reset_control_get_exclusive() reset_control_get_shared() reset_control_get_optional_exclusive() reset_control_get_optional_shared() of_reset_control_get_exclusive() of_reset_control_get_shared() of_reset_control_get_exclusive_by_index() of_reset_control_get_shared_by_index() devm_reset_control_get_exclusive() devm_reset_control_get_shared() devm_reset_control_get_optional_exclusive() devm_reset_control_get_optional_shared() devm_reset_control_get_exclusive_by_index() devm_reset_control_get_shared_by_index() Signed-off-by: Lee Jones Signed-off-by: Philipp Zabel
