linux-powkiddy-x55 is just the kernel dot org repo with a single
patch applied. Originally, this was meant to be a port to use LLVM,
but too much of compilation was broken by newer clang optimizations,
so porting to the newest release made more sense.

Get touchscreen going by using correct hex value as i2c address
Update display panel / DSS sections:
- Add comment to 'dss' section to explain need for a kernel configuration setting
which in an ideal world could be set in devicetree
- Set rotation property, panel-timing values, and comment on panel section in mcspi4
Set pinctrl entries for the device:
- Entries initially based on older u-boot and kernel board files and code, then
revised based on similar devices
- Add pinctrl values in &omap3_pmx_core and &omap3_pmx_core2 sections
- add pinctrl-names and pinctrl-0 entries for most devices
Start to get sound card / codec set up, although not working yet:
- Set correct codec compatible entry.
Device uses 'ti,tlv320dac3100', not 'ti,tlv320aic310x'
- Attempt to set sys_clkout2 clock for audio codec, but this is not working yet
- Add 'simple-audio-card' section
- Add &mcbsp2 section
- Add two regulators
Enable/ revise wifi section (mmc3 -> wifi)
Add vaux2 regulator section, used by mmc3/wifi
- Other devices have more comprehensive entries for the vmmc-supply and
vqmmc-supply values for wifi which should likely be used for this device as
well, but not implemented yet.
Allow device to actually turn off by setting system-power-controller property on
twl4030
- Add power ("ti,twl4030-power-idle-osc-off") section in twl, this seems to set
suspend/low power commands
Add/ update some items based on similar devices, such as:
- hfclk_26m - set on twl4030
- vpll2 - set regulator to always-on, supposedly for dss/dpi
Set some unused components as disabled: gpmc, mcspi1, mcspi2, mcspi3, uart3, uart4
- uart2 is disabled since bluetooth hasn't been tested. Device does not have
antenna for bluetooth
Many smaller updates:
- add pclk-sample property to lvds-encoder
- Correct accelerometer mount-matrix
- Set max8903_charger as power-supply for max17042 fuel gauge
- corrected touchscreen-size-.. properties to match 'native' orientation
- Add manufacturer model number to model string
- Revise max8903_charger section/ comments

Migrate the compiler to LLVM toolchain and update config as per required
and preferred config options by kconfigcheck.
Update the APKBUILD to follow some more recent standards as well.
And similar to linux-postmarketos-qcom-msm8974, activate
CONFIG_CC_OPTIMIZE_FOR_SIZE and CONFIG_KERNEL_XZ to get the kernel a bit
smaller again.

The PowerPC boot wrapper script in Linux currently requires a GNU
cross toolchain in PATH. This went unnoticed because we currently always
install GCC for native builds, but since recently only install a cross
GCC toolchain if clang is not used to build.
Indeed, we want to only build the kernel with clang and LLVM binutils.
There has been some discussion around fixing this in the past, and
Nathan Chancellor has written some patches that do fix it, but has
apparently not submitted them because the VDSO may require further
changes. I've followed up on the mailing list and asked about the
possibility to submit the patches without reworking the VDSO, since it
fixes this particular usecase nonetheless.
I've also considered installing the cross GCC package in the APKBUILD,
but that's not possible because pmbootstrap cannot evaluate conditional
dependencies. As it stands, we *need* to patch the kernel to get it
building, or revert the pmbootstrap patch, which I really want to avoid.
I'll do my best to get these patches integrated upstream.
[ci:skip-vercheck]: let's not rebuild all the architectures when we're
only touching ppc64le that isn't building in BPO
