[PATCH 0/3] clk: qcom: Migrate x1e80100 TCSR to clk_ref helper

[Qiang Yu]

The QREF block on X1E80100 supplies reference clocks to PCIe/USB/UFS
PHYs and requires dedicated LDO supplies to operate. The digital
control interface for QREF (clkref_en registers) resides in TCSR on
X1E80100. This series migrates the x1e80100 TCSR driver to the common
clkref_en helper introduced for Glymur/Mahua, and wires up the
required regulator supplies.

Patch 1 splits qcom,x1e80100-tcsr out of the shared qcom,sm8550-tcsr.yaml
into its own binding file and documents the QREF/refgen supply
properties, mirroring the qcom,glymur-tcsr.yaml split.

Patch 2 converts tcsrcc-x1e80100.c from local clk_branch definitions to
descriptor-based registration via qcom_clk_ref_probe(), reusing the
common regulator handling and enable/disable sequencing.

Patch 3 wires up the QREF/refgen LDO supplies on the boards Qualcomm
maintains directly: the CRD, QCP, Snapdragon Devkit, and the hamoa and
purwa IoT SoMs (purwa shares hamoa's QREF topology, so it reuses the
same qcom,x1e80100-tcsr compatible and supply set rather than needing a
dedicated one).

This patch series depends on:
