Qualcomm driver updates for v7.2 Enable QSEECOM and with that access to UEFI variables on the Surface Pro 12in laptop. Refactor the Geni Serial-Engine helper code to allow the serial engine drivers (such as I2C) to operate on targets where power and performance is controlled through an SCMI server instead of individual resources in Linux. Extend the LLCC driver to support reading its data from a System Cache Table (SCT) in memory instead of being hard coded per platform in the driver. Also add support for the Eliza platform. Add support for the Hawi platform to pd-mapper. Switch the SMEM driver to track partitions using xarray to handle the ever growing number of hosts better. Extend the socinfo driver with knowledge about the Nord, SM7750, IPQ9650, and Shikra SoCs, as well as PMAU0102, PMC1020H, PMIV0102, and PMIV0104 PMICs. Define UBWC 3.1 and add a couple of convenient helpers in the UBWC library for MDSS and Adreno. Fix a memory leak in the WCNSS firmware download mechanism. * tag 'qcom-drivers-for-7.2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (40 commits) soc: qcom: geni-se: Introduce helper APIs for performance control soc: qcom: geni-se: Introduce helper API for attaching power domains soc: qcom: geni-se: Add resources activation/deactivation helpers soc: qcom: geni-se: Handle core clk in geni_se_clks_off() and geni_se_clks_on() soc: qcom: geni-se: Introduce helper API for resource initialization soc: qcom: geni-se: Add geni_icc_set_bw_ab() function soc: qcom: geni-se: Refactor geni_icc_get() and make qup-memory ICC path optional soc: qcom: llcc-qcom: Fix NULL vs IS_ERR() bug in qcom_llcc_get_fw_config() soc: qcom: llcc-qcom: Add support for Eliza dt-bindings: cache: qcom,llcc: Document Eliza LLCC block soc: qcom: ubwc: add helper controlling AMSBC enablement soc: qcom: ubwc: define helper for MDSS and Adreno drivers soc: qcom: ubwc: define UBWC 3.1 soc: qcom: socinfo: Add SoC ID for Nord SA8797P dt-bindings: arm: qcom,ids: Add SoC ID for Nord SA8797P soc: qcom: socinfo: Add SoC ID for SM7750 dt-bindings: arm: qcom,ids: Add SoC ID for SM7750 soc: qcom: socinfo: Add PMIC PMAU0102 soc: qcom: socinfo: Add PMIV0102 & PMIV0104 PMICs firmware: qcom: scm: Allow QSEECOM on Surface Pro 12in ...
