Subject: [PATCH RESEND v3 0/3] phy: qcom: edp: Add missing ref clock to x1e80100
Date: Tue, 14 Oct 2025 12:46:02 +0300 [thread overview]
Message-ID: <20251014-phy-qcom-edp-add-missing-refclk-v3-0-078be041d06f@linaro.org> (raw)
According to documentation, the DP PHY on x1e80100 has another clock
called ref.
The current X Elite devices supported upstream work fine without this
clock, because the boot firmware leaves this clock enabled. But we should
not rely on that. Also, when it comes to power management, this clock
needs to be also disabled on suspend. So even though this change breaks
the ABI, it is needed in order to make we disable this clock on runtime
PM, when that is going to be enabled in the driver.
So rework the driver to allow different number of clocks, fix the
dt-bindings schema and add the clock to the DT node as well.

Changes in v3 (resend)
- picked-up Krzysztof's R-b tag for bindings patch
Changes in v3:
- Use dev_err_probe() on clocks parsing failure.
- Explain why the ABI break is necessary.
- Drop the extra 'clk' suffix from the clock name. So ref instead of
refclk.
- Link to v2: https://lore.kernel.org/r/20250903-phy-qcom-edp-add-missing-refclk-v2-0-d88c1b0cdc1b@linaro.org
Changes in v2:
- Fix schema by adding the minItems, as suggested by Krzysztof.
- Use devm_clk_bulk_get_all, as suggested by Konrad.
- Rephrase the commit messages to reflect the flexible number of clocks.
- Link to v1: https://lore.kernel.org/r/20250730-phy-qcom-edp-add-missing-refclk-v1-0-6f78afeadbcf@linaro.org
