[ Upstream commit 1c13d6060d612601a61423f2e8fbf9e48126acca ] Callers of of_qcom_ice_get() leak the device reference taken by of_find_device_by_node(). Introduce devm variant for of_qcom_ice_get(). Existing consumers need the ICE instance for the entire life of their device, thus exporting qcom_ice_put() is not required.

soc: qcom: Make the Qualcomm UFS/SDCC ICE a dedicated driver

2023-04-07T19:08:39+00:00

This takes the already existing duplicated support in both ufs-qcom and sdhci-msm drivers and makes it a dedicated driver that can be used by both mentioned drivers. The reason for this is because, staring with SM8550, the ICE IP block is shared between UFS and SDCC, which means we need to probe a dedicated device and share it between those two consumers. So let's add the ICE dedicated driver as a soc driver. Platforms that already have ICE supported, will use it as a library as the of_qcom_ice_get will return an ICE instance created for the consumer device. This allows the backwards compatibility with old-style devicetree approach. Also, add support to HW version 4.x since it works out-of-the-box with the current driver. The 4.x HW version is found on SM8550 platform.
