      reset: lpc18xx: get rid of global variables for restart notifier · 773fe726
      Joachim Eastwood authored
      Moving the notifier_block into the drivers priv struct allows us
      to retrive the priv struct with container_of and remove the
      global variables.

      reset: Add support for shared reset controls · 0b52297f
      Hans de Goede authored
      In some SoCs some hw-blocks share a reset control. Add support for this
      setup by adding new:
      methods to get a reset_control. Note that this patch omits adding of_
      variants, if these are needed later they can be easily added.
      This patch also changes the behavior of the existing exclusive
      reset_control_get() variants, if these are now called more then once
      for the same reset_control they will return -EBUSY. To catch existing
      drivers triggering this error (there should not be any) a WARN_ON(1)
      is added in this path.
      When a reset_control is shared, the behavior of reset_control_assert /
      deassert is changed, for shared reset_controls these will work like the
      clock-enable/disable and regulator-on/off functions. They will keep a
      deassert_count, and only (re-)assert the reset after reset_control_assert
      has been called as many times as reset_control_deassert was called.
      Calling reset_control_assert without first calling reset_control_deassert
      is not allowed on a shared reset control. Calling reset_control_reset is
      also not allowed on a shared reset control.

      reset: Share struct reset_control between reset_control_get calls · c15ddec2
      Hans de Goede authored
      Now that struct reset_control no longer stores the device pointer for
      the device calling reset_control_get we can share a single struct
      reset_control when multiple calls to reset_control_get are made for
      the same reset line (same id / index).
      This is a preparation patch for adding support for shared reset lines.

      reset: Make [of_]reset_control_get[_foo] functions wrappers · 6c96f05c
      Hans de Goede authored
      With both the regular, _by_index and _optional variants we already have
      quite a few variants of [of_]reset_control_get[_foo], the upcoming
      addition of shared reset lines support makes this worse.
      This commit changes all the variants into wrappers around common core
      functions. For completeness sake this commit also adds a new
      devm_get_reset_control_by_index wrapper.
