drm/bridge: synopsys: dw-mipi-dsi: Remove a redundant check on existence of bridge->encoder

2024-05-13T16:31:09+00:00

In the dw_mipi_dsi_bridge_attach() function, the check on the existence of bridge->encoder is not necessary, as it has already been checked in the drm_bridge_attach() function invocked by previous bridge or KMS driver. The previous drm_bridge_attach() will quit with a negative error code returned if it fails for some reasons, hence, it is guaranteed that the .encoder member of the struct drm_bridge is not NULL when dw_mipi_dsi_bridge_attach() function gets called. Remove the redundant checking codes "if (!bridge->encoder) { ... }".

Revert "drm: Switch DRM_DISPLAY_HELPER to depends on"

2024-05-02T15:58:23+00:00

This reverts commit e075e496f516bf92bc0cbaf94d64e8d4a6b58321, as helper code should always be selected by the driver that needs it, for the convenience of the final user configuring a kernel. The user who configures a kernel should not need to know which helpers are needed for the driver he is interested in. Making a driver depend on helper code means that the user needs to know which helpers to enable first, which is very user-unfriendly.

drm/bridge: dw-hdmi: Make DRM_DW_HDMI selectable

2024-04-05T13:08:40+00:00

Commit c0e0f139354c ("drm: Make drivers depends on DRM_DW_HDMI") turned select dependencies into depends on ones. However, DRM_DW_HDMI was not manually selectable which resulted in no way to enable the drivers that were now depending on it.

drm: Switch DRM_DISPLAY_HDMI_HELPER to depends on

2024-03-28T10:26:52+00:00

Most of our helpers have relied on being selected so far through Kconfig, but that creates issues when we have multiple layers of helpers with some depending on others. Indeed, select doesn't select a dependency's dependencies, and thus isn't super intuitive. Depends on however doesn't have that limitation, so we can just switch all the drivers that were selecting DRM_DISPLAY_HDMI_HELPER to depend on it.
