[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.

They talk to ACPI in same way. Only + difference between them is the way they do frequency transitions. + One uses MSRs and the other one uses IO ports. Functionaliy of + speedstep_centrino with ACPI hooks is now merged into acpi-cpufreq. + That means one common driver will support all Intel Enhanced Speedstep + capable CPUs. That means less confusion over name of + speedstep-centrino driver (with that driver supposed to be used on + non-centrino platforms). That means less duplication of code and + less maintenance effort and no possibility of these two drivers + going out of sync. + Current users of speedstep_centrino with ACPI hooks are requested to + switch over to acpi-cpufreq driver. speedstep-centrino will continue + to work using older non-ACPI static table based scheme even after this + date. + +Who: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> + +--------------------------- |
