1 STMicroelectronics STi family Sysconfig Peripheral SoftReset Controller
2 =============================================================================
4 This binding describes a reset controller device that is used to enable and
5 disable on-chip peripheral controllers such as USB and SATA, using
6 "softreset" control bits found in the STi family SoC system configuration
9 The actual action taken when softreset is asserted is hardware dependent.
10 However, when asserted it may not be possible to access the hardware's
11 registers and after an assert/deassert sequence the hardware's previous state
12 may no longer be valid.
14 Please refer to reset.txt in this directory for common reset
15 controller binding usage.

29 Specifying softreset control of devices
30 =======================================
32 Device nodes should specify the reset channel required in their "resets"
33 property, containing a phandle to the softreset device node and an
34 index specifying which channel to use, as described in reset.txt
39 resets = <&softreset STIH415_ETH0_SOFTRESET>;
42 Macro definitions for the supported reset channels can be found in:
