PCI: Add CONFIG_MMU dependency

2025-04-23T20:40:30+00:00

It turns out that there are no platforms that have PCI but don't have an
MMU, so adding a Kconfig dependency on CONFIG_PCI simplifies build testing
kernels for those platforms a lot, and avoids a lot of inadvertent build
regressions.

Add a dependency for CONFIG_PCI and remove all the ones for PCI specific
device drivers that are currently marked not having it.

There are a few platforms that have an optional MMU, but they usually
cannot have PCI at all. The one exception is Coldfire MCF54xx, but this is
mainly for historic reasons, and anyone using those chips should really use
the MMU these days.

drm/radeon: switch over to drm_exec v2

2024-11-20T12:59:34+00:00

Just a straightforward conversion without any optimization.

drm/radeon: Run DRM default client setup

2024-09-26T07:31:29+00:00

Rework fbdev probing to support fbdev_probe in struct drm_driver
and remove the old fb_probe callback. Provide an initializer macro
for struct drm_driver that sets the callback according to the kernel
configuration.

Call drm_client_setup() to run the kernel's default client setup
for DRM. Set fbdev_probe in struct drm_driver, so that the client
setup can start the common fbdev client.

The radeon driver specifies a preferred color mode depending on
the available video memory, with a default of 32. Adapt this for
the new client interface.

v5:
- select DRM_CLIENT_SELECTION
v2:
- style changes

fbdev: Use _IOMEM_ infix for I/O-memory helpers

2023-07-31T18:06:52+00:00

Change the infix for fbdev's I/O-memory helpers from _IO_ to _IOMEM_
to distiguish them from other types of I/O, such as file operations.
The helpers operate on memory ranges in the I/O address space and the
naming should make this clear. Adapt all users. No functional changes.

drm/radeon: Use regular fbdev I/O helpers

2023-06-01T10:26:50+00:00

Use the regular fbdev helpers for framebuffer I/O instead of DRM's
helpers. Radeon does not use damage handling, so DRM's fbdev helpers
are mere wrappers around the fbdev code.

By using fbdev helpers directly within each DRM fbdev emulation,
we can eventually remove DRM's wrapper functions entirely.

v4:
	* use initializer macros for struct fb_ops
v2:
	* use FB_IO_HELPERS option

drm: Only select I2C_ALGOBIT for drivers that actually need it

2023-01-10T10:15:44+00:00

While working on a drm driver that doesn't need the i2c algobit stuff I
noticed that DRM selects this code even though only 8 drivers actually use
it. While also only some drivers use i2c, keep the select for I2C for the
next cleanup patch. Still prepare this already by also selecting I2C for
the individual drivers.
