Samsung Exynos 7870 (codename: Joshua) is an ARM-v8 system-on-chip that was
announced in 2016. The chipset was found in several popular mid-range to
low-end Samsung phones, released within 2016 to 2019.

This patch series aims to add support for Exynos 7870, starting with the
most basic yet essential components such as CPU, GPU, clock controllers,
PMIC, pin controllers, etc.

Moreover, the series also adds support for three Exynos 7870 devices via
devicetree. The devices are:
 * Samsung Galaxy J7 Prime	- released 2016, codename on7xelte
 * Samsung Galaxy J6		- released 2018, codename j6lte
 * Samsung Galaxy A2 Core	- released 2019, codename a2corelte

Additional features implemented in this series include:
 * I2C	- touchscreen, IIO sensors, etc.
 * UART	- bluetooth and serial debugging
 * MMC	- eMMC, Wi-Fi SDIO, SDCard
 * USB	- micro-USB 2.0 interface
