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.
