Subject: [RESEND PATCH v5 0/5] ARM: da850: enable cpufreq in DT mode

From: Bartosz Golaszewski <bgolaszewski@...libre.com>

Note: resending rebased on top of v5.2-rc2

===

This series adds cpufreq-dt operating points for da850 boards supported
with device tree (da850-lcdk, da850-lego-ev3, da850-evm).

Last patch enables CPUFREQ_DT in davinci_all_defconfig.

v1 -> v2:
- use the VDCDC3_1.2V regulator as cpu-supply on da850-evm

v2 -> v3:
- drop patch 1, as the revision tag is in fact correctly passed to the kernel
  by u-boot
- only enable the 375 operating point for da850-evm as this is the standard
  frequency for this board

v3 -> v4:
- split the first patch into three separate changesets: one adding the
  operating points to the main dtsi and two enabling cpufreq on da850-lego-ev3
  and da850-lcdk
- remove the operating point not mentioned in the datasheet (415 MHz)
- fix commit message in patch 4/5

v4 -> v5:
- only enable a single OPP for da850-lcdk due to the problem with the OHCI
  controller becoming unresponsive after cpufreq transitions
- fix the name of the pmic on da850-evm

  ARM: dts: da850: add cpu node and operating points to DT
  ARM: dts: da850-lego-ev3: enable cpufreq
  ARM: dts: da850-lcdk: enable cpufreq
  ARM: davinci_all_defconfig: Enable CPUFREQ_DT
