[CPUFREQ][4/8] acpi-cpufreq: Mark speedstep-centrino ACPI as deprecated
Mark ACPI hooks in speedstep-centrino as deprecated. Change the order in which
speedstep-centrino and acpi-cpufreq (when both are in kernel) will be
added. First driver to be tried is now acpi-cpufreq, followed by
speedstep-centrino.
Add a note in feature-removal-schedule to mark this deprecation.

284 | What: ACPI hooks (X86_SPEEDSTEP_CENTRINO_ACPI) in speedstep-centrino driver | ||
285 | When: December 2006 | ||
286 | Why: Speedstep-centrino driver with ACPI hooks and acpi-cpufreq driver are | ||
287 | functionally very much similar. They talk to ACPI in same way. Only | ||
288 | difference between them is the way they do frequency transitions. | ||
289 | One uses MSRs and the other one uses IO ports. Functionaliy of | ||
290 | speedstep_centrino with ACPI hooks is now merged into acpi-cpufreq. | ||
291 | That means one common driver will support all Intel Enhanced Speedstep | ||
292 | capable CPUs. That means less confusion over name of | ||
293 | speedstep-centrino driver (with that driver supposed to be used on | ||
294 | non-centrino platforms). That means less duplication of code and | ||
295 | less maintenance effort and no possibility of these two drivers | ||
296 | going out of sync. | ||
297 | Current users of speedstep_centrino with ACPI hooks are requested to | ||
298 | switch over to acpi-cpufreq driver. speedstep-centrino will continue | ||
299 | to work using older non-ACPI static table based scheme even after this | ||
300 | date. | ||
