Incorrect lower freq profile for i5-5200u #407

Hi Piker,

I run the ssdtPRgen.sh and I obtain the following:

######################################### System information: Mac OS X 10.12.6 (16G1036) Brandstring: "Intel(R) Core(TM) i5-5200U CPU @ 2.20GHz"

Version: models.cfg v171 / Broadwell.cfg v151

Scope (PR) {222 bytes} with ACPI Processor declarations found in DSDT (ACPI 1.0 compliant)

Notice: The LFM frequency in Mac-E43C1C25D4880AD6.plist is set to 1300 MHz! This restriction can be lifted with help of freqVectorsEdit.sh from: https://github.com/Piker-Alpha/freqVectorsEdit.sh

Generating ssdt.dsl for a 'MacBookPro12,1' with board-id [Mac-E43C1C25D4880AD6] Broadwell Core i5-5200U processor [0x306D4] setup [0x0606] With a maximum TDP of 15 Watt, as specified by Intel Number logical CPU's: 4 (Core Frequency: 2200 MHz) Number of Turbo States: 5 (2300-2700 MHz) Number of P-States: 20 (800-2700 MHz) Adjusting C-States for detected (mobile) processor Injected C-States for CPU0 (C1,C3,C6,C7) Injected C-States for CPU1 (C1,C2,C3,C6,C7) Warning: 'cpu-type' may be set improperly (0x0606 instead of 0x0906)

Although it said 800-2700 MHz it does not scale down below 1,3ghz.

So as I read in other issue where you respond I run the freqVectorsEdit.sh in order to fix it. It change the lower freq to 800 MHz as expected in concordance to what indicates the profile and it works.

However on the intel Ark they indicate that the i5-5200u configurable TDP-down Frequency is 600 MHz. Maybe 800 it's for over models or not the U specification?

Thanks in advance.
