2022-06-07drm/mgag200: Store positions of I2C data and clock bits in device infoThomas Zimmermann1-24/+3
The bits for accessing I2C data and clock channels varies among models. Store them in the device-info structure for consumption by the DDC code.

2022-05-17drm/mgag200: Switch I2C code to managed cleanupThomas Zimmermann1-22/+11
Store the I2C state within struct mga_device and switch I2C to managed release. Simplifies the related code and lets us remove mga_connector_destroy().

2022-05-17drm/mgag200: Fail on I2C initialization errorsThomas Zimmermann1-5/+8
Initialization of the I2C adapter was allowed to fail. The mgag200 driver would have continued without DDC support. Had this happened in practice, it would have led to segmentation faults in the connector code. Resolve this problem by failing driver initialization on I2C- related errors. v2: * initialize 'ret' before drm_err() (kernel test robot) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Jocelyn Falempe <jfalempe@redhat.com> Tested-by: Jocelyn Falempe <jfalempe@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220516134343.6085-3-tzimmermann@suse.de

2013-03-08drm/mgag200: Bug fix: Renesas board now selects native resolution.Julia Lemire1-0/+1
Renesas boards were consistently defaulting to the 1024x768 resolution, regardless of the native resolution of the monitor plugged in. It was determined that the EDID of the monitor was not being read. Since the DAC is a shared line, in order to read from or write to it we must take control of the DAC clock. This can be done by setting the proper register to one. This bug fix sets the register MGA1064_GEN_IO_CTL2 to one. The DAC control line can be used to determine whether or not a new monitor has been plugged in. But since the hotplug feature is not one we will support, it has been decided to simply leave the register set to one.

2012-10-02UAPI: (Scripted) Remove redundant DRM UAPI header #inclusions from drivers/gpu/.David Howells1-1/+0
Remove redundant DRM UAPI header #inclusions from drivers/gpu/. Remove redundant #inclusions of core DRM UAPI headers (drm.h, drm_mode.h and drm_sarea.h). They are now #included via drmP.h and drm_crtc.h via a preceding patch. Without this patch and the patch to make include the UAPI headers from the core headers, after the UAPI split, the DRM C sources cannot find these UAPI headers because the DRM code relies on specific -I flags to make #include "..." work on headers in include/drm/ - but that does not work after the UAPI split without adding more -I flags.

2012-05-17mgag200: initial g200se driver (v2)Dave Airlie1-0/+156
This is a driver for the G200 server engines chips, it doesn't driver any of the Matrix G series desktop cards. It will bind to G200 SE A,B, G200EV, G200WB, G200EH and G200ER cards. Its based on previous work done my Matthew Garrett but remodelled to follow the same style and flow as the AST server driver. It also works along the same lines as the AST server driver wrt memory management. There is no userspace driver planned, xf86-video-modesetting should be used. It also appears these GPUs have no ARGB hw cursors. v2: add missing tagfifo reset + G200 SE memory bw setup pieces. Signed-off-by: Dave Airlie <airlied@redhat.com>
