drivers/reset/reset-ti-sci.c

3  * Texas Instruments System Control Interface (TI SCI) reset driver
8  * Loosely based on Linux kernel reset-ti-sci.c...
14 #include <reset-uclass.h>
18  * struct ti_sci_reset_data - reset controller information structure
53 	 * On TI SCI-based devices, the reset provider id field is used as a  in ti_sci_reset_of_xlate()
54 	 * device ID, and the data field is used as the associated reset mask.  in ti_sci_reset_of_xlate()
75  * ti_sci_reset_set() - program a device's reset
76  * @rst: Handle to a single reset signal
80  * reset using the TI SCI protocol. The device's reset is asserted if the
83  * reset register is read using a TI SCI device operation, the new value is
84  * set or un-set using the reset's mask, and the new reset value written by
120  * ti_sci_reset_assert() - assert device reset
121  * @rst: Handle to a single reset signal
123  * This function implements the reset driver op to assert a device's reset
126  * argument set to true for asserting the reset.
137  * ti_sci_reset_deassert() - deassert device reset
138  * @rst: Handle to a single reset signal
140  * This function implements the reset driver op to deassert a device's reset
143  * argument set to false for deasserting the reset.
154  * ti_sci_reset_status() - check device reset status
155  * @rst: Handle to a single reset signal
157  * This function implements the reset driver op to return the status of a
158  * device's reset using the TI SCI protocol. The reset register value is read
160  * status of the specific reset is extracted and returned using this reset's
161  * reset mask.
163  * Return: 0 if reset is deasserted, or a non-zero value if reset is asserted
