Klimt WiFi has product name Samsung Galaxy Tab S 8.4" and was released
in 2014. It has similar hardware to exynos5420-chagall-wifi and the
two devices can hence share a common base dtsi.
Same issues as for Chagall Wifi applies: CCI has to be disabled and
only 4 out of 8 CPUs are brought up at boot (see
https://lore.kernel.org/r/20220118185746.299832-4-henrik@grimler.se).

Klimt WiFi has the product name Samsung Galaxy Tab S 8.4". Board is
based on Exynos 5420, and has similar hardware to Chagall WiFi, but
with a smaller battery, smaller screen and another touchscreen
controller.
The device tree added here contains support for:
- UART access through a micro-usb cable with 619 kOhm between ID & GND
- Accessing the internal eMMC storage
- Accessing an external SD card
- USB, after configuration it is possible to ssh into the device
through a usb cable
