drm/imx/dcss: Don't call dev_set_drvdata(..., NULL);

2023-01-10T14:26:06+00:00

The driver core takes care about removing driver data, so this can be
dropped from the driver.

drm/imx/dcss: Drop if blocks with always false condition

2023-01-10T14:26:06+00:00

dcss_drv_platform_remove() is only called for a device after
dcss_drv_platform_probe() returned 0. In that case dev_set_drvdata() was
called with a non-NULL value and so dev_get_drvdata() won't return NULL.

drm/imx/dcss: stop using drm_bridge_connector_en/disable_hpd()

The functionality of drm_bridge_connector_enable_hpd() and
drm_bridge_connector_disable_hpd() is provided automatically by the
drm_kms_poll helpers. Stop calling these functions manually.

drm/imx: move IPUv3 driver into separate subdirectory

2022-12-16T17:40:29+00:00

The IPUv3 and DCSS driver are two totally separate DRM drivers. Having
one of them live in the drivers/gpu/drm/imx toplevel directory and the
other one in the dcss/ subdirectory is confusing. Move the IPUv3 driver
into its own subdirectory to make the separation more clear.

drm/imx: ipuv3-plane: Fix overlay plane width

2022-12-16T17:40:29+00:00

ipu_src_rect_width() was introduced to support odd screen resolutions
such as 1366x768 by internally rounding up primary plane width to a
multiple of 8 and compensating with reduced horizontal blanking.
This also caused overlay plane width to be rounded up, which was not
intended. Fix overlay plane width by limiting the rounding up to the
primary plane.

drm_rect_width(&new_state->src) >> 16 is the same value as
drm_rect_width(dst) because there is no plane scaling support.

drm: imx/dcss: Remove #ifdef guards for PM related functions

2022-12-12T13:07:01+00:00

Use the EXPORT_GPL_DEV_PM_OPS() and pm_ptr() macros to handle the PM
callbacks.

These macros allow the PM functions to be automatically dropped by the
compiler when CONFIG_PM is disabled, without having to use #ifdef
guards.

This has the advantage of always compiling these functions in,
independently of any Kconfig option. Thanks to that, bugs and other
regressions are subsequently easier to catch.

Move the generic fbdev implementation into its own source and header
file. Adapt drivers. No functional changes, but some of the internal
helpers have been renamed to fit into the drm_fbdev_ naming scheme.

v3:
	* rename drm_fbdev.{c,h} to drm_fbdev_generic.{c,h}
	* rebase onto vmwgfx changes
	* rebase onto xlnx changes

drm/imx/dcss: Don't set struct drm_driver.output_poll_changed

2022-11-05T16:05:53+00:00

Don't set struct drm_driver.output_poll_changed. It's used to restore
the fbdev console. But as DCSS uses generic fbdev emulation, the
console is being restored by the DRM client helpers already. See the
functions drm_kms_helper_hotplug_event() and
drm_kms_helper_connector_hotplug_event() in drm_probe_helper.c.
