dt-bindings: display: spacemit: add K3 Saturn DPU controller
8fb8708 
Document the Saturn display processing unit found on the SpacemiT K3 SoC.
The K3 instantiates two of them, one per display path. They share a
compatible: an instance differs only in which register window, interrupt,
clock and reset lines it takes.

dt-bindings: phy: add SpacemiT K3 Innosilicon DP PHY
7d45341 
The SpacemiT K3 DisplayPort controller drives its four transmit lanes
through an integrated Innosilicon DP PHY, one PHY per controller. Add a
binding so the controller can reference its transmit PHY and the pixel
clock the PHY's PLL sources.

The PHY's registers are interleaved with its parent controller's inside
one MMIO window, so it owns neither a reg nor a reset and is modelled as
a child of the controller.

It exposes its PLL-generated pixel clock through #clock-cells, so the
APMU pixel-clock mux can select it as a parent through the clock
framework.

dt-bindings: display: spacemit: add K3 Innosilicon DP/eDP controller
cd3ebd6 
Both K3 instances are the same IP and share one compatible; which one
behaves as eDP is decided by what its downstream port is wired to, not by
which register window it sits in, so the binding does not distinguish them.

dt-bindings: soc: spacemit: allow eDP/DP PHY PLL pixel clocks on K3 APMU
1cb5a33 
The APMU's eDP pixel-clock muxes select the DP PHY PLLs as parents, so the
K3 syscon takes two clock inputs the other variants do not have.

Gate them behind the K3 compatible instead of widening the shared clock
list, so a non-K3 syscon cannot silently accept clocks it has no mux for.

phy: spacemit: add Innosilicon DP TX PHY driver
3a73e89 
The PHY's registers are interleaved into its parent DP controller's MMIO
window rather than a window of its own, so it probes as a child of the
controller, carries no reg or reset, and reaches its registers through
the controller's regmap.

It registers its pixel PLL as a clock provider. That lets the display
controller ask for a mode's pixel rate through clk_set_rate(), and it
lets the APMU pixel-clock mux parent to the PHY through the clock
framework. Without it the controller and PHY would have to know each
other's registers.

clk: spacemit: k3: parent eDP/DP pixel clock to the PHY PLL
27ca425 
The APMU eDP/DP pixel-clock muxes were parented to a placeholder, because
their real parents (the DP PHY PLLs) did not exist as clocks yet. They do
now, so point each mux at its PLL and let the pixel clock reach the
controller through the clock framework.

drm/spacemit: add Saturn DPU register model
864353b 
The Saturn display processing unit is programmed through a set of
register blocks (composer, RDMA, timing generator, cmdlist engine,
display MMU) laid out identically in both SoC instances. Add the block
address map, the per-field word offset and mask tables consumed by the
field accessors, the interrupt bit layout and the compositor and
output-format ID encodings. The address map describes the whole
IP block on purpose, including blocks the driver does not touch; the
field tables carry the fields the driver programs, with each block's
full word count kept as its NWORDS extent.

Consumers arrive with the following patches; the driver only becomes
buildable once the final patch adds the Kconfig and Makefile glue.

drm/spacemit: add Saturn DPU core types, cmdlist and display MMU
3dc2b16 
Register programming of the Saturn DPU is batched: the driver builds
per-module register lists in memory and the hardware command-list
engine replays them at frame boundaries, while scanout buffers are
mapped through the DPU's private address translation unit (DMMU)
rather than scanned out by physical address.

Add the shared driver types, the MMIO field accessors, the trace
events, the command-list builder and the DMMU table code. Some DPU
configuration registers are write-only, so a read-modify-write would
corrupt neighbouring fields; byte- and halfword-aligned fields are
therefore written at their native width instead.

cc5fc96 
Add the atomic KMS implementation on top of the hardware backend: one
CRTC and one primary plane per DPU instance. atomic_check validates
the plane rectangle 1:1 against the mode and sizes the per-channel FBC
line buffer; atomic commit builds the cmdlist batches, maps the
framebuffer through the DMMU and arms the cfg-ready handshake, with
vblank events driven from the DPU interrupt.

e6398bd 
Add the DRM device for the SpacemiT K3 Saturn display processing unit
and hook the driver up to the build. The SoC has two DPU instances;
each drives one CRTC that scans out a single primary plane in linear
RGB at up to 3840x2160@60 and feeds a downstream DP/eDP controller
over an OF-graph endpoint. Buffers use drm_gem_shmem_helper. The
AFBC/compressed decode path is not exposed and writeback is not
implemented.

drm/spacemit: add Innosilicon DP/eDP controller bridge driver
c14ac1e 
Add the DP/eDP controller that sits downstream of the Saturn DPU. Two
identical instances share one compatible; the eDP-vs-DP role is board
wiring, so it is taken from the devicetree: an eDP panel always sits
under an aux-bus child node, an external DP connector never does.

The link is driven through the generic PHY framework, so the controller
never touches a PLL register. The controller's HPD interrupt is gated by
the DP pixel clock, which can be off exactly when a plug has to be
caught, so the connector is also polled and the interrupt path re-reads
the live level when it does fire.
