Store the pipeline elements in struct mi0283qt_device and initialize them as part of probing the device. Use mipi-dbi's existing helpers and initializer macros where possible. Effectively open-codes the modesetting code in the initializer helpers of mipi-dbi and simple-display. Mi0283qt requires a custom helper for CRTC enablement, and non-freeing cleanup of the pipeline. v2: - fix connector initialization - fix coding style Signed-off-by: Thomas Zimmermann --- drivers/gpu/drm/tiny/mi0283qt.c | 136 ++++++++++++++++++++++++++++---- 1 file changed, 122 insertions(+), 14 deletions(-) diff --git a/drivers/gpu/drm/tiny/mi0283qt.c b/drivers/gpu/drm/tiny/mi0283qt.c index f121e1a8a303..6655fd6f74d4 100644 --- a/drivers/gpu/drm/tiny/mi0283qt.c +++ b/drivers/gpu/drm/tiny/mi0283qt.c @@ -50,16 +50,48 @@ #define ILI9341_MADCTL_MX BIT(6) #define ILI9341_MADCTL_MY BIT(7) -static void mi0283qt_enable(struct drm_simple_display_pipe *pipe, - struct drm_crtc_state *crtc_state, - struct drm_plane_state *plane_state) +struct mi0283qt_device { + struct mipi_dbi_dev dbidev;
