[PATCH 0/5] ARM: OMAP2+: Add and enable operating-points-v2

[PATCH 0/5] ARM: OMAP2+: Add and enable operating-points-v2

[Dave Gerlach]

Hi,
This series adds the necessary changes to get proper operating-points-v2 tables
for AM335x/AM437x/DRA7xx/AM57xx TI SoCs. Doing this enables the ti-cpufreq
driver and allows the platform to detect which CPU OPPs are valid for the
configuration in use and enable them.

This series adds complete tables for am335x and adds 1GHz support for all
beaglebone black boards and updates the already merged but unused am437x table
to match the finalized DT bindings. It also moves the existing dra7xx/am57xx
OPPs to OPPv2 but does not enable 1.5GHz yet as this requires multiregulator
support which will come at a later date.

Also, now that so many TI platforms will depend on the ti-cpufreq driver let's
add CONFIG_ARM_TI_CPUFREQ to omap2plus_defconfig to enable it as part of the
default configuration.

Pushed a branch containing these patches on top of v4.11-rc1 if anyone wants
to try it out [1].

Regards,
Dave

[PATCH 1/5] ARM: dts: am33xx: Add updated operating-points-v2 table for cpu

[Dave Gerlach]

After the ti-cpufreq driver has been added, we can now drop the
operating-points table present in am33xx.dtsi for the cpu and add an
operating-points-v2 table with all OPPs available for all silicon
revisions. Also add necessary data for use by ti-cpufreq to selectively
enable the appropriate OPPs at runtime as part of the operating-points
table.

Information from AM335x Data Manual, SPRS717i, Revised December 2015,
Table 5-7.

[PATCH 4/5] ARM: dts: dra7: Add updated operating-points-v2 table for cpu

[Dave Gerlach]

After the ti-cpufreq driver has been added, we can now drop the
operating-points table present in dra7.dtsi for the cpu and add an
operating-points-v2 table with all OPPs available for all silicon
revisions. Also add necessary data for use by ti-cpufreq to selectively
enable the appropriate OPPs at runtime as part of the operating-points
table.

As we now need to define voltage ranges for each OPP, we define the
minimum and maximum voltage to match the ranges possible for AVS class0
voltage as defined by the DRA7/AM57 Data Manual, with the exception of
using a range for OPP_OD based on historical data to ensure that SoCs
from older lots still continue to boot, even though more optimal voltages
are now the standard. Once an AVS Class0 driver is in place it will be
possible for these OPP voltages to be adjusted to any voltage within the
provided range.

[PATCH 3/5] ARM: dts: am4372: Update operating-points-v2 table for cpu

[Dave Gerlach]

The operatings-points-v2 table for am4372 was merged before any user of
it was present in the kernel and before the binding had been finalized.
The new ti-cpufreq driver and binding expects the platform specific
properties to be part of the operating-points-v2 table rather than the
cpu node so let's move them there as the only user is the ti-cpufreq
driver.

[PATCH 5/5] ARM: omap2plus_defconfig: Enable support for ti-cpufreq

[Dave Gerlach]

AM335x, AM437x, DRA7xx, and AM57xx platforms all now depend on
ti-cpufreq driver to enable proper OPPs for use with cpufreq, so
enable the same.
