Add Exynos850 SoC and WinLink's E850-96 board support. A short overview of series additions and modifications:
- USI driver: configures UART block
- PMU driver: connects AP UART lines to uart1 pins)
- Exynos850 clock driver: generates UART clocks
- Exynos850 pinctrl driver: mux UART pins
- serial_s5p: UART driver
- Exynos850 SoC: dtsi files and MMU maps
- E850-96 board: dts files, defconfig, board file and doc
Most of the code was borrowed from mainline Linux kernel (where this board is already enabled) and adapted for U-Boot. Preliminary preparation for this series includes next patches / series (already merged):
- commit 585a2aaac2ac ("arm: exynos: Include missing CPU header in soc.c")
- commit c9ab9f30c8e4 ("arm: exynos: Include missing CPU header in gpio.h")
- commit 11bd2787deff ("watchdog: s5p_wdt: Include missing CPU header")
- commit 08cfa971a717 ("exynos: Avoid duplicate reset_cpu with SYSRESET enabled")
- commit f655090901dc ("clk: exynos: Add header guard for clk-pll.h")
- commit 2227f4c0afed ("serial: s5p: Fix clk_get_by_index() error code check")
- commit a0615ffc99a5 ("serial: s5p: Remove common.h inclusion")
- commit 5ad21de6bae0 ("serial: s5p: Use livetree API to get "id" property")
- commit e79f630dbf67 ("serial: s5p: Use named constants for register values")
- commit a627f2802a71 ("serial: s5p: Improve coding style")
- commit 33e7ca5a9b6a ("serial: s5p: Use dev_read_addr_ptr() to get base address")
- commit 6219b47c4d91 ("board: samsung: Fix SYS_CONFIG_NAME configs in axy17lte Kconfig")
- commit 470682ace1e0 ("configs: Remove unneeded SYS_CONFIG_NAME from a*y17lte defconfigs")
and series [1]. For more detailed description please see the board documentation (added in PATCH #12) and corresponding commit messages.
Changes in v2:
- PATCH 4: Removed unnecessary mode param
- PATCH 4: Removed usi->dev and used priv data instead
- PATCH 4: Used .of_plat_data callback for dts parsing
- PATCH 7: Fixed Thomas Abraham e-mail
- PATCH 9: Fixed incorrect driver description (comment)
- Collected Reviewed-by tags
- Rebased on top of most recent U-Boot/master
