* hwmon: (ad7418) Convert to a new-style i2c driverJean Delvare2008-07-16
| | | | | | | | | | | The ad7418 driver is only used on embedded platforms where i2c devices can easily be declared in platform code. Thus a new-style i2c driver makes perfect sense. This lets us get rid of quirky detection code (these chips have no identification registers) and shrinks the binary driver size by 38%.

In fact, even if that were not the case, there doesn't seem to be any place where G is set without also setting I (_PAGE_NO_CACHE), so the test for I is sufficient as a condition to clear _PAGE_COHERENT when filling the hash table.

The main impetus for this compat set is the need to support partition migration, especially from processor P(n) to processor P(n+1), where performance software that's running in the new partition may not be knowledgeable about processor P(n+1). If a performance tool determines it does not support the physical processor, but is told (via the PPC_FEATURE_PSERIES_PERFMON_COMPAT bit) that the processor supports the notion of the PMU compat set, then the performance tool can surface just those events to the user of the tool. PPC_FEATURE_PSERIES_PERFMON_COMPAT indicates that the PMU supports at least this basic subset of events which is compatible across POWER processor lines.
