Merge tag 'soc-newsoc-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull new SoC support from Arnd Bergmann:
 "These five newly supported chips come with both devicetree
  descriptions and the changes to wire them up to the build system for
  easier bisection.

  The chips in question are:

   - Marvell PXA1908 was the first 64-bit mobile phone chip from Marvell
     in the product line that started with the Digital StrongARM SA1100
     based PDAs and continued with the Intel PXA2xx that dominated early
     smartphones. This one only made it only into a few products before
     the entire product line was cut in 2015.

   - The QiLai SoC is made by RISC-V core designer Andes Technologies
     and is in the 'Voyager' reference board in MicroATX form factor. It
     uses four in-order AX45MP cores, which is the midrange product from
     Andes.

   - CIX P1 is one of the few Arm chips designed for small workstations,
     and this one uses 12 Cortex-A720/A520 cores, making it also one of
     the only ARMv9.2 machines that one can but at the moment.

   - Axiado AX3000 is an embedded chip with relative small Cortex-A53
     CPU cores described as a "Trusted Control/Compute Unit" that can be
     used as a BMC in servers. In addition to the usual I/O, this one
     comes with 10GBit ethernet and and a 4TOPS NPU.

   - Sophgo SG2000 is an embedded chip that comes with both RISC-V and
     Arm cores that can run Linux. This was already supported for RISC-V
     but now it also works on Arm

  One more chip, the Black Sesame C1200 did not make it in tirm for the
  merge window"

+
+description:
+  In the Andes platform such as QiLai SoC, the PLIC module is instantiated a
+  second time with all interrupt sources tied to zero as the software interrupt
+  controller (PLIC_SW). PLIC_SW directly connects to the machine-mode
+  inter-processor interrupt lines of CPUs, so RISC-V per-CPU local interrupt
+  controller is the parent interrupt controller for PLIC_SW. PLIC_SW can
+  generate machine-mode inter-processor interrupts through programming its

+
+maintainers:

+
+description:
+  The Cixtech mailbox controller, used in the Cixtech Sky1 SoC,
+  is used for message transmission between multiple processors
+  within the SoC, such as the AP, PM, audio DSP, SensorHub MCU,
+  and others
+
+  Each Cixtech mailbox controller is unidirectional, so they are
+  typically used in pairs-one for receiving and one for transmitting.
+
+  Each Cixtech mailbox supports 11 channels with different transmission modes
+    channel 0-7 - Fast channel with 32bit transmit register and IRQ support
+    channel 8   - Doorbell mode,using the mailbox as an interrupt-generating
+                   mechanism.
+    channel 9   - Fifo based channel with 32*32bit depth fifo and IRQ support
+    channel 10  - Reg based channel with 32*32bit transmit register and
+                   Doorbell+transmit acknowledgment IRQ support
+
+  In the CIX Sky1 SoC use case, there are 4 pairs of mailbox controllers
+    AP <--> PM - using Doorbell transfer mode
+    AP <--> SE - using REG transfer mode
+    AP <--> DSP - using FIFO transfer mode
+    AP <--> SensorHub - using FIFO transfer mode
