Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC driver updates from Arnd Bergmann:
"This contains driver changes that are tightly connected to SoC
specific code. Aside from smaller cleanups and bug fixes, here is a
list of the notable changes.

New device drivers:

- The Turris Mox router has a new "moxtet" bus driver for its
on-board pluggable extension bus. The same platform also gains a
firmware driver.

- The Samsung Exynos family gains a new Chipid driver exporting using
the soc device sysfs interface

- A similar socinfo driver for Qualcomm Snapdragon chips.

- A firmware driver for the NXP i.MX DSP IPC protocol using shared
memory and a mailbox

Other changes:

- The i.MX reset controller driver now supports the NXP i.MX8MM chip

- Amlogic SoC specific drivers gain support for the S905X3 and A311D
chips

- A rework of the TI Davinci framebuffer driver to allow important
cleanups in the platform code

- A couple of device drivers for removed ARM SoC platforms are
removed. Most of the removals were picked up by other maintainers,
this contains whatever was left"

Merge remote-tracking branch 'arm-soc/arm/drivers' into HEAD

bus: Add support for Moxtet bus

On the Turris Mox router different modules can be connected to the main
CPU board: currently a module with a SFP cage, a module with MiniPCIe
connector, a PCIe pass-t

bus: Add support for Moxtet bus

On the Turris Mox router different modules can be connected to the main
CPU board: currently a module with a SFP cage, a module with MiniPCIe
connector, a PCIe pass-through MiniPCIe connector module, a 4-port
switch module, an 8-port switch module, and a 4-port USB3 module.

For example:
[CPU]-[PCIe-pass-through]-[PCIe]-[8-port switch]-[8-port switch]-[SFP]

Each of this modules has an input and output shift register, and these
are connected via SPI to the CPU board.

Via SPI we are able to discover which modules are connected, in which
order, and we can also read some information about the modules (eg.
their interrupt status), and configure them.
From each module 8 bits can be read (of which low 4 bits identify the
module) and 8 bits can be written.

For example from the module with a SFP cage we can read the LOS,
TX-FAULT and MOD-DEF0 signals, while we can write TX-DISABLE and
RATE-SELECT signals.

This driver creates a new bus type, called "moxtet". For each Mox module
it finds via SPI, it creates a new device on the moxtet bus so that
drivers can be written for them.

It also implements a virtual interrupt controller for the modules which
send their interrupt status over the SPI shift register. These modules
do this in addition to sending their interrupt status via the shared
interrupt line. When the shared interrupt is triggered, we read from the
shift register and handle IRQs for all devices which are in interrupt.

The topology of how Mox modules are connected can then be read by
listing /sys/bus/moxtet/devices.
