[U-Boot] [PATCH 0/5 v2] Add DT based ethernet driver for SMDK5250
This patch series enables the DT support on SMDK5250. Ethernet is the first driver whose discovery is based on DT node. More DT based drivers to be added subsequently
Changes since v1: - Renamed the smdk5250.h file to exynos5250-dt.h to create a common configuration file which can be used by all the boards based on exynos5250 using Device Tree. - Created a new smdk5250.h file specifying the dts file specific to SMDK5250 - Incorporated minor nit (removal of blank lines)
Hatim Ali (5): EXYNOS5: FDT: add initial dts file for EXYNOS5250, SMDK5250 fdt: exynos5: Add DT node definition for SROM and SMSC9215 exynos5: Add DT based driver for SMC911X ethernet exynos5: config: Rename the smdk5250.h to exynos5250-dt.h SMDK5250: config: Add configuration file for SMDK5250 board

This patch adds initial dts file for EXYNOS5250 SoC. This dts file currently include only ethernet devices and properties. More devices to be added in subsequent patches. Also add the dts file for SMDK5250 board which uses the EXYNOS5250 dts file.

Add the compatibility string and constant for the ethernet driver so the device tree parsing code can recognize it.

Create a common configuration file for all exynos5250 based boards. Going forward we will be using DT based driver discovery for all the boards based on Exynos5. The different boards added will have there own config.h files which internally will include this file and specify their specific DT files.

This patch series enables the DT support on SMDK5250. Ethernet is the first driver whose discovery is based on DT node. More DT based drivers to be added subsequently
Changes since v1: - Renamed the smdk5250.h file to exynos5250-dt.h to create a common configuration file which can be used by all the boards based on exynos5250 using Device Tree. - Created a new smdk5250.h file specifying the dts file specific to SMDK5250 - Incorporated minor nit (removal of blank lines)
I went through this series again, and it looks good to me.
The series:
