[PATCH v2 0/4] Add reset support to EN7581 clk driver

[Lorenzo Bianconi]

Introduce reset-controller support to the Airoha EN7581 clock module.

Changes since v1:
- squash patch 1/5 and 2/5
- introduce reset line mapping in order to take into account possible holes in
  reset definitions
- fix error path in en7523_clk_probe()

Lorenzo Bianconi (4):
  dt-bindings: clock: airoha: Add reset support to EN7581 clock binding
  arm64: dts: airoha: Add reset-controller support to EN7581 clock node
  clk: en7523: Add reset-controller support for EN7581 SoC
  clk: en7523: Remove pcie prepare/unpreare callbacks for EN7581 SoC

[PATCH v2 4/4] clk: en7523: Remove pcie prepare/unpreare callbacks for EN7581 SoC

[Lorenzo Bianconi]

Get rid of prepare and unpreare callbacks for PCIe clock since they can
be modeled as a reset line cosumed by the PCIe driver
(pcie-mediatek-gen3)
