It has DPI interface and supports a maximum resolution of WXGA along with 2 RPFs to support the blending of two picture layers and raster operations (ROPs). The DU module is connected to VSPD. Add RZ/G2UL DU support. Signed-off-by: Biju Das Reviewed-by: Laurent Pinchart --- v3->v4: * Used "&" instead of "==" in rzg2l_du_start_stop() for scalability. * Restored port variable in struct rzg2l_du_output_routing * Updated rzg2l_du_encoders_init() to handle port based on hardware indices. v2->v3: * Avoided the line break in rzg2l_du_start_stop() for rstate. * Replaced port->du_output in struct rzg2l_du_output_routing and dropped using the port number to indicate the output type in rzg2l_du_encoders_init(). * Updated rzg2l_du_r9a07g043u_info and rzg2l_du_r9a07g044_info v1->v2: * No change. --- drivers/gpu/drm/renesas/rz-du/rzg2l_du_crtc.c | 8 +++++++- drivers/gpu/drm/renesas/rz-du/rzg2l_du_drv.c | 11 +++++++++++ drivers/gpu/drm/renesas/rz-du/rzg2l_du_kms.c | 3 ++- 3 files changed, 20 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/renesas/rz-du/rzg2l_du_crtc.c b/drivers/gpu/drm/renesas/rz-du/rzg2l_du_crtc.c index 6e7aac6219be..c4c1474d487e 100644 --- a/drivers/gpu/drm/renesas/rz-du/rzg2l_du_crtc.c +++ b/drivers/gpu/drm/renesas/rz-du/rzg2l_du_crtc.c @@ -28,6 +28,7 @@ #include "rzg2l_du_vsp.h" #define DU_MCR0 0x00 +#define DU_MCR0_DPI_OE BIT(0) #define DU_MCR0_DI_EN BIT(8) #define DU_DITR0 0x10 @@ -216,9 +217,14 @@ static void rzg2l_du_crtc_put(struct rzg2l_du_crtc *rcrtc) static void rzg2l_du_start_stop(struct rzg2l_du_crtc *rcrtc, bool start) { + struct rzg2l_du_crtc_state *rstate = to_rzg2l_crtc_state(rcrtc->crtc.state); struct rzg2l_du_device *rcdu = rcrtc->dev; + u32 val = DU_MCR0_DI_EN; - writel(start ?
