[U-Boot] [PATCH v3 0/8] Add support for Espresso7420 board

[Thomas Abraham]

Changes since v2:
- changes based on comments from Simon Glass and Minkyu Kang.

This patch series add support for Espresso7420 board. This board is
the development/evaluation platform for Exynos7420 SoC. The SoC is
composed of quad Cortex-A57 block, a quad Cortex-A53 block and
various other peripherals. The board includes multiple components
such as the EMMC/Codec and support multiple interconnect interfaces
including HDMI and USB.

The first two patches add Exynos7420 pinctrl driver support which
was initially posted seperatly but now included in this series.
Thanks to Simon Glass and Minkyu Kang for their review. The rest
of the patches add Exynos7420 clock driver support, minor changes
in the S5P serial driver, Exynos7420 SoC support and Espresso7420
board support.

Thomas Abraham (8):
  pinctrl: add the DM_UC_FLAG_SEQ_ALIAS flag for numbering the devices
  pinctrl: Add pinctrl driver support for Exynos7420 SoC
  clk: exynos: add clock driver for Exynos7420 Soc
  serial: s5p: get the port id number from the alias of the device node
  serial: s5p: use clock api to get clock rate
  arm: exynos: realign the code to allow support for newer 64-bit
    platforms
  arm: exynos: add support for Exynos7420 SoC
  board: samsung: add initial Espresso7420 board support
