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 shared reset triggered_count decrement on error

2017-02-17T07:11:47Z

For a shared reset, when the reset is successful, the triggered_count is incremented when trying to call the reset callback, so that another device sharing the same reset line won't trigger it again. If the reset has not been triggered successfully, the trigger_count should be decremented. The code does the opposite, and decrements the trigger_count on success. As a consequence, another device sharing the reset will be able to trigger it again. Fixed be removing negation in from of the error code of the reset function.

reset: make zx2967 explicitly non-modular

2017-02-02T15:32:09Z

The Kconfig currently controlling compilation of this code is: config RESET_ZX2967 bool "ZTE ZX2967 Reset Driver ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. Since builtin_platform_driver() was already in use, the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments. We don't replace module.h with init.h since the file does not appear to use __init prefix anywhere. Cc: Jun Nie Signed-off-by: Paul Gortmaker Reviewed-by: Baoyou Xie Signed-off-by: Philipp Zabel

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: constify reset_control_ops structures

2017-01-12T10:12:07Z

Declare reset_control_ops structures as const as they are only stored in the ops field of a reset_controller_dev structure. This field is of type const struct reset_control_ops *, so reset_control_ops structures having this property can be declared as const.
