  • In "make menuconfig", reset drivers are currently lined up together
    with the reset sub-system menu, like this:

    -*- Reset Controller Support ----
    < > Hi6220 Reset Driver

    (It also means, the menu "Reset Controller Support" is always empty.)

    "Hi6220 Reset Driver" should go into the sub-menu of the
    "Reset Controller Support".

  • This patch adds softreset, powerdown and picophy reset controllers for
    the STiH407 SoC.

    With this patch three new devices are registered: -
    1. st,stih407-powerdown
    2. st,stih407-softreset
    3. st,stih407-picophyreset

    All three devices use system configuration registers mapped via regmap to
    perform the reset or powerdown. The powerdown controller also has
    an acknowledgement.

    A separate picophy reset controller manages the different reset channels within
    the picophy, which have a different polarity to the other system softresets.
    Managing these different picophy softreset channels is necessary to correctly
    handle resuming from suspend when USB2 devices are plugged into the USB3 port.

  • This patch adds a reset controller platform driver for the STiH416
    SoC. This initial version provides a compatible driver for the
    "st,stih416-powerdown" device, which registers a system configuration
    register based reset controller that controls the powerdown state of
    hardware such as the on-chip USB host controllers.

  • This patch adds a reset controller implementation for STMicroelectronics
    STi family SoCs; it allows a group of related reset like controls found
    in multiple system configuration registers to be represented by a single
    controller device. System configuration registers are accessed through
    the regmap framework and the mfd/syscon driver.

    The implementation optionally supports waiting for the reset action to
    be acknowledged in a separate status register and supports both
    active high and active low reset lines. These properties are common across
    all the reset channels in a specific reset controller instance, hence
    all channels in a paritcular controller are expected to behave in the
    same way.
