[PATCH 0/6] Initial Samsung Galaxy A8 (2018) support

[David Virag <virag.david003@gmail.com>]

Add basic initial support for the Samsung Galaxy A8 (2018) smartphone.
This phone is also known as "jackpotlte" and under the model name
"SM-A530F". In its current state this should work on most if not all
Exynos7885 phones/devices released.

As of now, it supports I2C nodes (all disabled by default) and UART
console with basic clock support in place.

To access the UART console on the A8, there are two methods:
  -You can open up the device and solder directly to some debug pins
   close to the display connector.
  -Through I2C you can set the S2MU004 MFD chip to multiplex the SoC's
   UART lines to the d+ and d- on the USB Type-C port of the device.

Note that UART works on 1.8 volts, so plugging in a normal USB cable
while multiplexed to UART may fry the SoC.

Everything was tested through UART by using a minimal driver that sets
the S2MU004 to multiplex UART.

The preferred way to boot this device is using my Minimal S-Boot Wrapper
[1] to work around some issues caused by the stock, and non-replacable
Samsung S-Boot bootloader.
