As both SDCC and UFS drivers use the ICE with duplicated implementation,
while none of the currently supported platforms make use concomitantly
of the same ICE IP block instance, the new SM8550 allows both UFS and
SDCC to do so. In order to support such scenario, there is a need for
a unified implementation and a devicetree node to be shared between
both types of storage devices. So lets drop the duplicate implementation
of the ICE from both SDCC and UFS and make it a dedicated (soc) driver.

For now, only SM8550 has been added to support the new approach. This
also involves adding support for HW version 4.x.

The v5 is here:
https://lore.kernel.org/all/20230403200530.2103099-1-abel.vesa@linaro.org/

Changes since v5:
 * See each individual patch for changelogs.

Changes since v4:
 * dropped the SDHCI dt-bindings patch as it will be added along
   with the first use of qcom,ice property from an SDHCI DT node

Abel Vesa (6):
  dt-bindings: crypto: Add Qualcomm Inline Crypto Engine
  dt-bindings: ufs: qcom: Add ICE phandle
  soc: qcom: Make the Qualcomm UFS/SDCC ICE a dedicated driver
  scsi: ufs: ufs-qcom: Switch to the new ICE API
  mmc: sdhci-msm: Switch to the new ICE API
  arm64: dts: qcom: sm8550: Add the Inline Crypto Engine node
