Sony ever so graciously provides GPIO line names in their downstream
kernel (though sometimes they are not 100% accurate and you can judge
that by simply looking at them and with what drivers they are used).
Add these to the PDX213&214 DTSIs to better document the hardware.
Diff between 223 and 224:
pm8350b
< gpio-line-names = "NC", /* GPIO_1 */
> gpio-line-names = "CAM_PWR_A_CS", /* GPIO_1 */
< "NC",
> "CAM_PWR_LD_EN",
pm8350c
< "NC",
> "WLC_TXPWR_EN",
Which is due to different camera power wiring on 213 and lack of an
additional SLG51000 PMIC on 214.

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.
