drm/arm/hdlcd: Use devm_platform_ioremap_resource()

2023-03-17T14:57:17Z

According to commit 7945f929f1a7 ("drivers: provide devm_platform_ioremap_resource()"), convert platform_get_resource(), devm_ioremap_resource() to a single call to Use devm_platform_ioremap_resource(), as this is exactly what this function does. Since 'struct platform_device *pdev = to_platform_device(drm->dev)', 'drm->dev' is equivalent to 'pdev->deva'.

arm/malidp: Use GEM DMA fbdev emulation

2023-03-14T16:07:47Z

Use the fbdev emulation that is optimized for DMA helpers. Avoids possible shadow buffering and makes the code simpler. Signed-off-by: Thomas Zimmermann Reviewed-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20230313155138.20584-4-tzimmermann@suse.de

drm/arm/malidp: use sysfs_emit in show function callback

2023-02-03T13:05:33Z

According to Documentation/filesystems/sysfs.rst, the show() callback function of kobject attributes should strictly use sysfs_emit() instead of sprintf() family functions.

drm/arm/komeda: Remove unnecessary include statements for drm_crtc_helper.h

2023-01-18T08:25:30Z

Several source files include drm_crtc_helper.h without needing it or only to get its transitive include statements; leading to unnecessary compile-time dependencies. Drop drm_crtc_helper.h where possible. v2: * update commit message (Sam) Signed-off-by: Thomas Zimmermann Reviewed-by: Sam Ravnborg Acked-by: Jani Nikula Acked-by: Alex Deucher Link: https://patchwork.freedesktop.org/patch/msgid/20230116131235.18917-5-tzimmermann@suse.de

drm: Include where needed

2023-01-13T12:18:35Z

Include in source files that need it. Some of DRM's source code gets OF header via drm_crtc_helper.h and , which can leed to unnecessary recompilation. In drm_modes.c, add a comment on the reason for still including . The header file is required to get KHZ2PICOS(). The macro is part of the UAPI headers, so it cannot be moved to a less prominent location. v2: * include in komeda_drv.c (kernel test robot) Signed-off-by: Thomas Zimmermann Acked-by: Liviu Dudau # komeda Acked-by: Maxime Ripard Link: https://patchwork.freedesktop.org/patch/msgid/20230111130206.29974-3-tzimmermann@suse.de

drm/arm/hdlcd: use new debugfs device-centered functions

2023-01-06T19:15:08Z

Replace the use of drm_debugfs_create_files() with the new drm_debugfs_add_files() function, which center the debugfs files management on the drm_device instead of drm_minor. Moreover, remove the debugfs_init hook and add the debugfs files directly on hdlcd_drm_bind(), before drm_dev_register().

drm/arm/malidp: remove calls to drm_mode_config_cleanup()

2022-11-16T10:33:45Z

drm_mode_config_init() simply calls drmm_mode_config_init(), hence cleanup is automatically handled through registering drm_mode_config_cleanup() with drmm_add_action_or_reset(). While at it, get rid of the deprecated drm_mode_config_init() and replace it with drmm_mode_config_init() directly.
