[PATCH 00/15] SDX55 devicetree updates

[PATCH 00/15] SDX55 devicetree updates

[Manivannan Sadhasivam]

Hi Bjorn,

This series updates the SDX55 devicetree by adding below features:

- A7 PLL
- APCS mailbox
- CPUFreq using clk and regulator
- SMP2P
- IMEM, PIL
- SCM
- Interconnect
- Telit FN980 TLB board
- Thundercomm T55 dev board
- Modem remoteproc

Except remoteproc, all of the driver patches already merged. Remoteproc
patch will be submitted separately.

Thanks,
Mani

[PATCH 01/15] ARM: dts: qcom: sdx55: Add support for A7 PLL clock

[Manivannan Sadhasivam]

On SDX55 there is a separate A7 PLL which is used to provide high
frequency clock to the Cortex A7 CPU via a MUX.

[PATCH 03/15] ARM: dts: qcom: sdx55: Add CPUFreq support

[Manivannan Sadhasivam]

Add CPUFreq support to SDX55 platform using the cpufreq-dt driver.
There is no dedicated hardware block available on this platform to
carry on the CPUFreq duties. Hence, it is accomplished using the CPU
clock and regulators tied together by the operating points table.
