Subject: [PATCH v5 0/7] Add support for Clock controllers for Glymur SoC

Introduce the support for Global clock controller(GCC), TCSR and the RPMH clock controller for

Qualcomm's next gen compute SoC - Glymur.

Device tree changes aren't part of this series and will be posted separately after the
official announcement of the Glymur SoC.

Changes in v5:
 - wrap commit message for 'TCSR Clock Controller binding'
 - Fix the GCC documentation binding for the clock descriptions and
   clock phandles for 'pcie 4b --> pcie 3b' and remove extra 'pcie 6b'.
 - Add RB tag from
	- [Bjorn], [Krzysztof] for RPMh/TCSR clock binding.
	- [Abel] for TCSR Clock Controller driver.
	- [Dmitry] for GCC clock controller driver.
 - Link to v4: https://lore.kernel.org/all/20250813-glymur-clock-controller-v4-v4-0-a408b390b22c@oss.qualcomm.com/

Changes in v4:
 - Update the commit message for all dt-bindings to incorporate "Glymur SoC".
 - Add the xo parent for the TCSR CC clocks[Abel]
 - Update the GCC driver to cleanup dfs_rcgs as part of 'qcom_cc_driver_data'[Dmitry]
 - Add RB tag from [Konrad]
 - Fix the broken previous patchset links.
 - Link to v3: https://lore.kernel.org/lkml/20250729-glymur-gcc-tcsrcc-rpmhcc-v3-0-227cfe5c8ef4@oss.qualcomm.com/

Changes in v3:
- Update the commit message for all the dt-bindings [Krzysztof]
- Update the commit message as required.
- Link to v2: https://lore.kernel.org/all/20250724-glymur_clock_controllers-v2-0-ab95c07002b4@oss.qualcomm.com/

Changes in v2:
- Drop second/last, redundant "bindings" in TCSR and also align the
  filename [Krzysztof]
- Update the year to the copyright [Krzysztof]
- Align to the new Kconfig name CLK_GLYMUR_GCC/TCSR [Abel, Bjorn]
- Use qcom_cc_probe() for tcsrcc [Dmitry]
- Add RB tag from [Dmitry] to patch #5
- Link to v1: https://lore.kernel.org/lkml/20250716152017.4070029-1-pankaj.patil@oss.qualcomm.com/
