Subject: [PATCH v3 0/2] Add driver support for ESWIN eic7700 SoC reset controller

From: Xuyang Dong <dongxuyang@...incomputing.com>

There are some register offsets in reset dt-bindings. It could be used.
Therefore, we want to keep these bindings. I don't known if it meets
the requirements.

PIPE_RST_CTRL, TBU_RST_CTRL and TEST_RST_CTRL are not used in this
driver. Therefore, these are left out.

Updates:

  dt-bindings: reset: eswin: Documentation for eic7700 SoC
  v2 -> v3:
    1. Drop syscon and simple-mfd from yaml and code, because these are
       not necessary.
    2. Update description to introduce reset controller.
    3. Add reset control indices for dt-bindings.
    4. Keep the register offsets in dt-bindings.

  v1 -> v2:
    1. Clear warnings/errors for using "make dt_binding_check".
    2. Update example, change parent node from sys-crg to reset-controller
       for reset yaml.
    3. Drop the child node and add '#reset-cells' to the parent node.
    4. Drop the description, because sys-crg block is changed to reset-
       controller.
    5. Change hex numbers to decimal numbers going from 0, and drop the
       not needed hardware numbers.

  reset: eswin: Add eic7700 reset driver
  v2 -> v3:
    1. Change syscon_node_to_regmap() to MMIO regmap functions, because
       droped syscon.
    2. Add BIT() in function eswin_reset_set() to shift the reset
       control indices.
    3. Remove forced type conversions from function eswin_reset_of_
       xlate_lookup_id().

  v1 -> v2:
    1. Modify the code according to the suggestions.
    2. Use eswin_reset_assert() and eswin_reset_deassert in function
       eswin_reset_reset().
    3. Place RESET_EIC7700 in Kconfig and Makefile in order.
    4. Use dev_err_probe() in probe function.
