* drm/fb-helper: Perform all fbdev I/O with the same implementationThomas Zimmermann2022-11-051-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Implement the fbdev's read/write helpers with the same functions. Use the generic fbdev's code as template. Convert all drivers. DRM's fb helpers must implement regular I/O functionality in struct fb_ops and possibly perform a damage update. Handle all this in the same functions and convert drivers. The functionality has been used as part of the generic fbdev code for some time. The drivers don't set struct drm_fb_helper.fb_dirty, so they will not be affected by damage handling. For I/O memory, fb helpers now provide drm_fb_helper_cfb_read() and drm_fb_helper_cfb_write(). Several drivers require these. Until now tegra used I/O read and write, although the memory buffer appears to be in system memory. So use _sys_ helpers now. v3: * fix docs (Javier) v2: * rebase onto vmwgfx changes Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221103151446.2638-18-tzimmermann@suse.de

* | drm/exynos: Fix return type for mixer_mode_valid and hdmi_mode_validNathan Huckleberry2022-09-262-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The field mode_valid in exynos_drm_crtc_ops is expected to be of type enum drm_mode_status (*mode_valid)(struct exynos_drm_crtc *crtc, const struct drm_display_mode *mode); Likewise for mode_valid in drm_connector_helper_funcs. The mismatched return type breaks forward edge kCFI since the underlying function definition does not match the function hook definition. The return type of mixer_mode_valid and hdmi_mode_valid should be changed from int to enum drm_mode_status.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the downstream kernels for exynos4 and exynos5 devices, there is an undocumented register that controls the order of the RGB output. It can be set to either normal order or reversed, which enables BGR support for those SoCs. This patch enables the BGR support for all the SoCs that were found to have at least one device with this logic in the corresponding downstream kernels.

In such case the code will continue and try to convert NULL gpiod to irq what in turn fails. The failure is then propagated and driver is not registered.
