This series proposes a new way to deal with alias nodes and introduces a function to take care of it.
Drivers can now request an ordered list of compatible nodes in a single step. This simplifies node discovery for drivers (and keeps this nasty code in a common place).
If DEBUG is defined the alias function will print messages in the event of a warning/error.
Changes in v2: - Add test_fdtdec command to test fdtdec_find_aliases_for_id() - Allow gaps in the list returned to the caller - Improve alias checking algorithm to reduce run time - Rename function to fdtdec_find_aliases_for_id() - Skip nodes marked as disabled
Changes in v3: - Change 'continue' to 'break' in last loop, since we are done anyway - Change fdtdec-test.c to fdtdec_test.c to fit better with U-Boot conventions - Fix typos and add two assert() checks - Remove varargs declaration (hang-over from previous implementation) - Use COMPAT_UNKNOWN instead of COMPAT_NVIDIA_TEGRA20_I2C for test
