reset: add TI SYSCON based reset driver Add a reset-controller driver for performing reset management of various devices present on the SoC, with the reset registers shared between devices in a common register memory space. This driver uses the syscon/regmap frameworks to actually implement the various reset functionalities needed by the reset consumer devices. Signed-off-by: Andrew F. Davis <afd@ti.com> [s-anna@ti.com: add documentation, syscon name change] Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> 2016-06-27 12:12:17 -05:00

reset: constify reset_control_ops structures 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.
