Hi folks,
This series adds initial support for the Samsung Galaxy S20 Series and also
initial board support for the Samsung Galaxy S20 5G (SM-G981B)
codenamed x1s.
The S20 Series feature a lot of similarities in their configuration
and internally Samsung named the common devicetrees in their
downstream kernel 'hubble', please note hubble excludes the
S20 FE series and Note20 series.
The device trees have been tested with dtbs_check W=1
and results in no warnings.
This initial bringup consists of:
* pinctrl
* gpio-keys
* simple-framebuffer
This is enough to reach a shell in an initramfs. More platform support
will be added in the future.
Just like SM-N981B, the preferred way to boot the upstream kernel is
by using a shim bootloader, called uniLoader [1], which works around
some issues with the stock, non-replacable Samsung S-LK bootloader.
For example, the stock bootloader leaves the decon trigger control
unset, which causes the framebuffer not to refresh.
Device functionality depends on the patch series from Igor Belwon:
"Add minimal Exynos990 SoC and SM-N981B support"
[1] https://github.com/ivoszbg/uniLoader
Changes in v3:
- Fix oversight in yaml
- Decommonise memory map
Changes in v2:
- Add Samsung Galaxy S20 into device tree bindings
- Add support for Samsung Galaxy S20 as well as the 5G variant now
- Fix typo in Samsung Galaxy S20 5G commit message
Kind regards,
Umer
