This series enables clock support on the Samsung Exynos pin controller
driver.

This is required on Socs like Google Tensor gs101, which implement
fine-grained clock control / gating, and as such a running bus clock is
required for register access to work.

Changes in v3:
- fix binding for non-gs101 platforms (Krzysztof), sorry I missed that
  initially :-(
- Link to v2: https://lore.kernel.org/r/20240426-samsung-pinctrl-busclock-v2-0-8dfecaabf020@linaro.org

Changes in v2:
- propagate clk_enable() errors in samsung_pinmux_setup(), i.e.
  struct pinmux_ops::set_mux()
- move clk_enable()/disable() outside bank->slock lock, to avoid
  possible deadlocks due to locking inversion (Krzysztof)
- fix some comments (Krzysztof)
- use 'ret' instead of 'i' in samsung_pinctrl_resume() (Krzysztof)
- Link to v1: https://lore.kernel.org/r/20240425-samsung-pinctrl-busclock-v1-0-898a200abe68@linaro.org
