* dm: core: Replace of_offset with accessorSimon Glass2017-02-08-5/+6
| | | | | | | | | At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

* common: miiphyutil: Work and report phy address in hex in mdio cmdMichal Simek2016-12-02-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | It is confusing that mdio commands work and report phy id as decimal value when mii is working with hex values. For example: ZynqMP> mdio list gem: 21 - TI DP83867 <--> ethernet@ff0e0000 ZynqMP> mdio read ethernet@ff0e0000 0 Reading from bus gem PHY at address 21: 0 - 0x1140 ZynqMP> mii dump 21 0 Incorrect PHY address. Range should be 0-31 ... ZynqMP> mii dump 15 0. (1140) -- PHY control register -- (8000:0000) 0.15 = 0 reset U-Boot normally takes hex values that's why this patch is changing mdio command to handle hex instead of changing mii command to handle decimal values.
