1STMicroelectronics STi family Sysconfig Peripheral SoftReset Controller2=============================================================================3 4This binding describes a reset controller device that is used to enable and5disable on-chip peripheral controllers such as USB and SATA, using6"softreset" control bits found in the STi family SoC system configuration7registers.8 9The actual action taken when softreset is asserted is hardware dependent.10However, when asserted it may not be possible to access the hardware's11registers and after an assert/deassert sequence the hardware's previous state12may no longer be valid.13 14Please refer to reset.txt in this directory for common reset15controller binding usage.16 17Required properties:18- compatible: Should be "st,stih407-softreset";19- #reset-cells: 1, see below20 21example:22 23 softreset: softreset-controller {24 #reset-cells = <1>;25 compatible = "st,stih407-softreset";26 };27 28 29Specifying softreset control of devices30=======================================31 32Device nodes should specify the reset channel required in their "resets"33property, containing a phandle to the softreset device node and an34index specifying which channel to use, as described in reset.txt35 36example:37 38 ethernet0{39 resets = <&softreset STIH415_ETH0_SOFTRESET>;40 };41 42Macro definitions for the supported reset channels can be found in:43 44include/dt-bindings/reset/stih407-resets.h45
