    Subject[PATCH v4 0/6] drm: lcdif: Add i.MX93 LCDIF support
    Date
    Hi,

    This patch set aims to add i.MX93 LCDIF display controller support
    in the existing LCDIF DRM driver. The LCDIF embedded in i.MX93 SoC
    is essentially the same to those embedded in i.MX8mp SoC. Through
    internal bridges, i.MX93 LCDIF may drive a MIPI DSI display or a LVDS
    display or a parallel display.

    Patch 1/6 adds device tree binding support for i.MX93 LCDIF in the
    existing fsl,lcdif.yaml.

    Patch 2/6 drops lcdif->bridge NULL pointer check as a cleanup patch.

    Patch 3/6~5/6 prepare for adding i.MX93 LCDIF support step by step.

    Patch 6/6 adds i.MX93 LCDIF compatible string as the last step of
    adding i.MX93 LCDIF support.

    v3->v4:
    * Improve warning message when ignoring invalid LCDIF OF endpoint ids in
    patch 5/6. (Alexander)
    * Use 'new_{c,p}state' instead of 'new_{crtc,plane}_state' in patch 3/6.
    (Alexander)
    * Simplify lcdif_crtc_reset() by calling lcdif_crtc_atomic_destroy_state()
    in patch 3/6. (Alexander)
    * Add '!crtc->state' check in lcdif_crtc_atomic_duplicate_state() in patch 3/6.
    (Alexander)
    * Collect Alexander's R-b tags on patch 1/6, 2/6 and 6/6.

    v2->v3:
    * Fix a trivial typo in patch 6/6's commit message.

    v1->v2:
    * Add Krzysztof's A-b and Marek's R-b tags on patch 1/6.
    * Split patch 2/2 in v1 into patch 2/6~6/6 in v2. (Marek, Alexander)
    * Drop '!remote ||' from lcdif_attach_bridge(). (Lothar)
    * Add comment on the 'base' member of lcdif_crtc_state structure to
    note it should always be the first member. (Lothar)
    * Drop unneeded 'bridges' member from lcdif_drm_private structure.
    * Drop a comment about bridge input bus format from lcdif_crtc_atomic_check().
