[PATCH v4 0/5] clk: qcom: Introduce initial clock controllers for Maili SoC

[Taniya Das <taniya.das@oss.qualcomm.com>]

Introduce the initial set of clock controller bindings and driver
support for the upcoming Qualcomm Maili SoC.

Maili is a new mobile SoC from Qualcomm. It is a derivative of the
Hawi SoC and shares most of its clock topology. Where the hardware is
identical, Maili reuses the existing Hawi drivers via fallback
compatible strings. Where Maili diverges — specifically in the Global
Clock Controller (GCC), which carries an additional QUPv3 wrapper
(WRAP5) — the Hawi GCC driver is extended to handle both SoCs.

The series covers the following clock controllers:

  - RPMH clock controller: identical to Hawi; uses qcom,hawi-rpmh-clk
    as fallback.
  - TCSR clock controller: identical to Hawi; uses qcom,hawi-tcsrcc
    as fallback.
  - Global Clock Controller (GCC): extends the Hawi GCC driver with
    eight additional QUPV3 WRAP5 clocks present only on Maili.
  - CPUCP mailbox controller: software-compatible with X1E80100; uses
    qcom,x1e80100-cpucp-mbox as fallback.

The devicetree for Maili will be upstreamed later.

Changes in v4:
  - Rebase the binding of tcsr to linux-next.
  - Add RB-by from Konrad Dybcio on the GCC driver patch.
  - Link to v3: https://lore.kernel.org/r/20260724-maili_initial_clock-v3-0-45b577241c91@oss.qualcomm.com

Changes in v3:
  - Update the comment for extending the array appropriately size.
  - Add RB-by [Krzysztof] from v2
  - Link to v2: https://lore.kernel.org/r/20260713-maili_initial_clock-v2-0-79548f0bb58f@oss.qualcomm.com

 Changes in v2:
  - Split the new Maili-only QUPv3 WRAP5 clock IDs out of
    qcom,hawi-gcc.h into a new qcom,maili-gcc.h header (which includes
    qcom,hawi-gcc.h), instead of adding them directly to the Hawi
    header. [Krzysztof]
  - Update the GCC driver to include the maili-gcc header.
  - Link to v1: https://lore.kernel.org/r/20260618-maili_initial_clock-v1-0-d6ede0352113@oss.qualcomm.com
