drm/mgag200: Add VGA-BMC output

2024-08-09T06:13:45+00:00

Duplicate VGA output to VGA-BMC output and update all code for Matrox
server chips. The new output represents a VGA output that has a BMC
attached to it. No functional changes so far.

drm/mgag200: Consolidate VGA output

2024-06-13T07:31:25+00:00

The various models have common code for the VGA output's encoder and
connector. Move everything into a single shared source file. Remove some
obsolete initializer macros. No functional changes.

drm/mgag200: Provide per-device callbacks for PIXPLLC

2022-07-29T14:01:47+00:00

Move the PIXPLLC code into per-model source files and wire it up
with per-model callbacks. No functional changes.

The PIXPLLC pixel-clock is part of the CRTC, but really separate
hardware that varies with each model of the G200. Move the PIXPLLC
code for each model into the per-model source file and call it from
CRTC helpers via device functions.

This allows to remove struct mgag200_pll and the related code. The
new callbacks behave like the CRTC's atomic_check and atomic_enable
functions.

drm/mgag200: Provide per-device callbacks for BMC synchronization

2022-07-29T14:01:47+00:00

Move the BMC-related code into its own file and wire it up with device
callbacks.

While programming a new display mode, G200EW3 and G200WB have to de-
synchronize with the BMC. Synchronization is done via VIDRST pins
and controlled via VRSTEN and HRSTEN bits. Move the BMC code behind
a serviceable interface and call it from the CRTC's enable and
disable functions.

drm/mgag200: Implement new init logic

2022-06-07T07:39:54+00:00

Rework mgag200_regs_init() and mgag200_mm_init() into device preinit
and init functions. The preinit function, mgag200_device_preinit(),
requests and maps a device's I/O and video memory. The init function,
mgag200_device_init() initializes the state of struct mga_device.
Splitting the initialization between the two functions is necessary
to perform per-model operations between the two calls, such as reading
the unique revision ID on G200SEs.

drm/mgag200: Initialize each model in separate function

2022-06-07T07:39:44+00:00

Add a separate initializer function for each model. Add separate
devic structures for G200 and G200SE, which require additional
information.

Also move G200's and G200SE's helpers for reading the BIOS and
version id into model-specific code.

drm/mgag200: Abstract pixel PLL via struct mgag200_pll

2021-08-08T18:14:05+00:00

Move all PLL compute and update functions into mgag200_pll.c. No
functional changes to the rsp algorithms.

Introduce struct mgag200_pll and mgag200_pll_funcs. The data strutures
abstract the details of each revision's PLL. Perform calls to compute
and update functionality via function pointers. Init the PLL once as
part of the driver initialization.
