Add support for SONY Xperia 1 III (PDX215) and 5 III (PDX214) smartphones. Both are based on the SM8350 Sagami platform and feature some really high-end specs, such as: - 4K (1 III / PRO-I) / 1080p (5 III), 120Hz HDR OLED 10-bit panels - USB-C 3.1 with HDMI in (yes, phone as display!) and DP out - 5G - 8 or 12 gigs of ram, 128/256/512 gigs of storage - A 3.5mm headphone jack, a RGB notification LED and a uSD card slot :) - IP65/68 dust/water resistance - Dual front-firing speakers and a lot of microphones - Crazy complex camera hardware (especially on the PRO-I), which includes 4 cameras, an RGBIR sensor and a 3D iToF The aforementioned PRO-I (PDX217) is not supported in this patch, because even though it shares most of the code with 1 III, nobody really has it (yet?) This only adds basic support for booting to a USB shell with a bootloader-enabled display, support for all the awesome hardware listed above will (hopefully) come (hopefully) soon. In order to get a working boot image, you need to run (e.g. for 1 III): cat arch/arm64/boot/Image.gz arch/arm64/boot/dts/qcom/sm8350-sony-xperia-\ sagami-pdx215.dtb > .Image.gz-dtb mkbootimg \ --kernel .Image.gz-dtb \ --ramdisk some_initrd.img \ --pagesize 4096 \ --base 0x0 \ --kernel_offset 0x8000 \ --ramdisk_offset 0x1000000 \ --tags_offset 0x100 \ --cmdline "SOME_CMDLINE" \ --dtb_offset 0x1f00000 \ --header_version 1 \ --os_version 11 \ --os_patch_level 2021-10 \ # or newer -o boot.img-sony-xperia-pdx215 Then, you need to flash it on the device and get rid of all the vendor_boot/dtbo mess: fastboot flash boot boot.img-sony-xperia-pdx215 fastboot erase vendor_boot fastboot flash dtbo emptydtbo.img fastboot reboot Where emptydtbo.img is a tiny file that consists of 2 bytes (all zeroes), doing a "fastboot erase" won't cut it, the bootloader will go crazy and things will fall apart when it tries to overlay random bytes from an empty partition onto a perfectly good appended DTB.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
