[PATCH 0/4] Add cpufreq and USB support for AM62D2

[PATCH 0/4] Add cpufreq and USB support for AM62D2

[Paresh Bhagat]

This patch series introduces following changes:

* Patch 1 fixes the register length in main_pmx/padconfig for AM62D
 and AM62A.

* Patch 2 enables USB support for AM62D2-EVM by adding pinmux and device
 tree nodes.

* Patch 3 adds AM62D2 SoC to cpufreq-dt-platdev blacklist so that
 cpufreq is handled by the ti-cpufreq driver instead of the
 generic cpufreq-dt driver.

* Patch 4 extends ti-cpufreq to register AM62D2 SoC support by
 reusing the am62a7_soc_data.

[PATCH 3/4] cpufreq: dt-platdev: Blacklist ti,am62d2 SoC

[Paresh Bhagat]

Add ti,am62d2 SoC to the blacklist as the ti-cpufreq driver will handle
creating the cpufreq-dt platform device after it completes and ensure
it is not created twice.

from hardware and pass to OPP layer. AM62D shares the same configuations
as AM62A so use existing am62a7_soc_data.

Please don't randomly mix patches into single series. Here patches 1/4
and 2/4 have no bearing on cpufreq driver changes in 3/4 and 4/4. They
even go through different trees.

Needs a Fixes tag and Cc stable tag. Read [1]

Please add a link to the documentation to support your claim.

Please do not mix things up to maintainers. Please post patches #1,2
separately to DT maintainers - these do not have any relationship with
the rest of the driver patches.

Thanks for the review. I will keep patches in separate series for
