[U-Boot] [PATCH v3 00/12] cpsw: enable DM_ETH on dra74 and am437x evms

This series adds the following * Enable DM_ETH on dra74, am437x gp and am437x sk evms. * Add support to verify of_is_device_conpatible() based on linux implementation * Fix an issue in fdtdec get addr for address and size cell length
Changes from initial version: * removed 02/11 fix size cell and address cell parse from DT and used fdtdec_get_addr_size_auto_noparent() to get mdio base and gmii_sel register address. Added as separate patch in this series. * used fdt_node_check_compatible() to check if the device or machine is compatible with the given compatible string. * change first argument from node offset to device pointer so that in future it is will be easy to migrate out of indexing DT by offsets.
Changes from v2: * Just rebase on top of u-boot/master and resolve conflicts.

Provide an api to check whether the given device or machine is compatible with the given compat string which helps in making decisions in drivers based on device or machine compatible.

OK, please update the function comment. Also what do you think about adding a new of.h /of.c files to hold this function prototype? I really want to keep the APIs clean.

Does one function really matter? In that case, it should still go in fdtdec, you can keep the of_ prefix. Perhaps we should use that more generally. My reason for not is that the current fdtdec API is not the same as of_. It uses (const void *blob, int offset) instead of (struct of_node *node), etc.

Since dra7x platforms address bus is define as 64 bits to support LAPE, fdtdec_get_addr() returns a invalid address for mdio based and gmii_sel register address. Fixing this by using fdtdec_get_addr_size_auto_noparent() which will derive address cell and size cell from its parent.
