[U-Boot] [PATCH v3 0/3] Add mipi dsi support for evb-rk3288.

[U-Boot] [PATCH v3 0/3] Add mipi dsi support for evb-rk3288.

[Eric Gao]

Changes in v2:
-Cancel the force convert for dev_read_addr return value type.
-Change regs type from "void __iomem" to "uintptr_t" for the head file.

Changes in v1:
-Change function name from rk_display_enable to rk_mipi_enable.
-Use IS_ERR to judge the return status.
-Use dev_read_addr to replace devfdt_get_addr.
-Make the subject more intelligible.
