Subject: [PATCH v5 0/2] arm64: dts: qcom: x1e80100: Describe SDCs and
 enable support on QCP

The X1E80100 has two SDHC controllers (called SDC2 and SDC4).
Describe both of them and enable the SDC2 on QCP. This brings
SD card support for the microSD port on QCP.

The SDC4 is described but there is no device outthere yet that makes
use of it, AFAIK.

Changes in v5:
- Switched the interconnect paths tags to QCOM_ICC_TAG_ALWAYS and
  QCOM_ICC_TAG_ACTIVE_ONLY, as Konrad suggested. 
- Actually enabled the sdhc on QCP (status = "okay" was missing).
- Rebased to fix conflicts due to smb2360 nodes which were already
  merged.
- Link to v4: https://lore.kernel.org/r/20241212-x1e80100-qcp-sdhc-v4-0-a74c48ee68a3@linaro.org

Changes in v4:
- Squashed the pinconf for SDC2 into the patch that describes the
  controllers.
- Reworded the commit messages a bit.
- Link to v3: https://lore.kernel.org/r/20241022-x1e80100-qcp-sdhc-v3-0-46c401e32cbf@linaro.org

Changes in v3:
- Reordered the default and sleep pinconfs. Also the bias and
  drive-strength properties. As per Konrad's suggestion.
- Link to v2: https://lore.kernel.org/r/20241014-x1e80100-qcp-sdhc-v2-0-868e70a825e0@linaro.org

Changes in v2:
- rebased on next-20241011
- dropped the bindings schema update patch
- dropped the sdhci-caps-mask properties from both
  controllers as SDR104/SDR50 are actually supported
- Link to v1: https://lore.kernel.org/r/20241008-x1e80100-qcp-sdhc-v1-0-dfef4c92ae31@linaro.org
