      arm64: dts: meson-g12b-odroid-n2: enable DVFS · d14734a0
      Neil Armstrong authored
      Enable DVFS for the Odroid-N2 by setting the clock, OPP and supply
      for each cores of each CPU clusters.
      
      The first cluster uses the "VDDCPU_B" power supply, and the second
      cluster uses the "VDDCPU_A" power supply.
      
      Each power supply can achieve 0.73V to 1.01V using 2 distinct PWM
      outputs clocked at 800KHz with an inverse duty-cycle.
      
      DVFS has been tested by running the arm64 cpuburn at [1] and cycling
      between all the possible cpufreq translations of each cluster and
      checking the final frequency using the clock-measurer, script at [2].

      arm64: dts: meson-g12b-khadas-vim3: add initial device-tree · c6d29c66
      Christian Hewitt authored
      The Khadas VIM3 uses the Amlogic S922X or A311S SoC, both based on the
      Amlogic G12B SoC family, on a board with the same form factor as the
      VIM/VIM2 models. It ships in two variants; basic and
      pro which differ in RAM and eMMC size:
      
      - 2GB (basic) or 4GB (pro) LPDDR4 RAM
      - 16GB (basic) or 32GB (pro) eMMC 5.1 storage
      - 16MB SPI flash
      - 10/100/1000 Base-T Ethernet
      - AP6398S Wireless (802.11 a/b/g/n/ac, BT5.0)
      - HDMI 2.1 video
      - 1x USB 2.0 + 1x USB 3.0 ports
      - 1x USB-C (power) with USB 2.0 OTG
      - 3x LED's (1x red, 1x blue, 1x white)
      - 3x buttons (power, function, reset)
      - IR receiver
      - M2 socket with PCIe, USB, ADC & I2C
      - 40pin GPIO Header
      - 1x micro SD card slot
      
      A common meson-g12b-khadas-vim3.dtsi is added to support both S922X and
      A311D SoCs supported by two variants of the board.
