Add support for Sony Xperia 1 V, a.k.a PDX234. This device is a part
of the SoMC SM8550 Yodo platform.
This commit brings support for:
* Remoteprocs (sans modem for now)
* Flash LED (the notification LED is gone :((((()
* SD Card
* USB (*including SuperSpeed*) + PMIC_GLINK (it's funky, requires a replug
with an cable flip sometimes..)
* Most regulators
* Part of I2C-connected peripherals (notably no touch due to a
driver bug)
* PCIe0 (PCIe1 is unused)
Do note display via simplefb is not supported, as the display is blanked
upon exiting XBL.
To create a working boot image, you need to run:
cat arch/arm64/boot/Image.gz arch/arm64/boot/dts/qcom/sm8550-sony-xperia-\
yodo-pdx234.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 2 \
-o boot.img-sony-xperia-pdx234
Then, you need to flash it on the device and get rid of all the
vendor_boot/dtbo mess:
// You have to either pull vbmeta{"","_system"} from
// /dev/block/bootdevice/by-name/ or build one as a part of AOSP build process
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
fastboot --disable-verity --disable-verification flash vbmeta_system \
vbmeta_system.img
fastboot flash boot boot.img-sony-xperia-pdx234
fastboot erase vendor_boot
fastboot erase recovery
fastboot flash dtbo emptydtbo.img
fastboot erase init_boot // ? I don't remember if it's necessary, sorry
fastboot continue
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.
DTBc check reports:
arch/arm64/boot/dts/qcom/sm8550-sony-xperia-yodo-pdx234.dtb: pcie-1-phy-aux-clk: 'clock-frequency' is a required property
from schema $id: http://devicetree.org/schemas/clock/fixed-clock.yaml#
So you'll probably need:
&pcie_1_phy_aux_clk {
status = "disabled";
};
