+title: STMicroelectronics STi family Sysconfig Picophy SoftReset Controller
+

+
+description: |
+  This binding describes a reset controller device that is used to enable and
+  disable on-chip PicoPHY USB2 phy(s) using "softreset" control bits found in
+  the STi family SoC system configuration registers.
+
+  The actual action taken when softreset is asserted is hardware dependent.
+  However, when asserted it may not be possible to access the hardware's
+  registers and after an assert/deassert sequence the hardware's previous state
+  may no longer be valid.
