Subject: [PATCH 2/2] ARM: dts: qcom: Add SDX55 Modem and MTP board support
Add basic devicetree support for SDX55 Modem and MTP board from
Qualcomm. The SDX55 modem features an ARM Cortex A7 CPU which forms the
Application Processor Sub System (APSS) along with standard Qualcomm
peripherals like GCC, TLMM, BLSP, QPIC, BAM etc... Along with these,
there exists the networking parts such as IPA, MHI, PCIE-EP, EMAC
etc..
Currently, this basic devicetree support includes GCC, RPMh clock, INTC
and Debug UART.
