Merge https://source.denx.de/u-boot/custodians/u-boot-snapdragon
Support is added for 5 new Qualcomm SoCs:
* QCM2290 and SM6115 are low and mid range SoCs used on the RB1 and RB2
respectively. SM6115 is also used in some mid-range smartphones/tablets.
Initial support includes buttons and USB (host and gadget).
* SM8250 is a flagship SoC from 2020 used on the RB5, as well as many flagship
smartphones. The board can boot to a U-Boot prompt, but is missing regulators
necessary for USB support.
* SM8550, and SM8650 are flagship mobile SoCs from 2023 and 2024
respectively. Found on many high end smartphones.
In addition:
* Support is added for the Schneider HMIBSC board.
* mach-snapdragon switches to OF_UPSTREAM
* IPQ40xx gets several regressions fixed and some overall cleanup.
* The MSM serial driver gains the ability to generate the bit-clock
automatically, no longer relying on a custom DT property.
* The Qualcomm SMMU driver gets a generic compatible (so per-SoC compatibles
don't need to be added).
* Support for the GENI I2C controller is added.
* The qcom SPMI driver has SPMI v5 support fixed, and v7 support added.
* The qcom sdhci driver gets some fixes for SDCC v5 support.
* SDM845 gains sdcard support
* Support is added for the Synopsys eUSB2 PHY driver (used on SM8550 and SM8650)
* SYS_INIT_SP_BSS_OFFSET is set to 1.5M to give us more space for FDTs.
* RB2 gets a work-around to fix the USB dr_mode property before booting Linux.
