Please remove FB_SYNC_EXT support.
+static void imx_ipu_fb_disable_overlay(struct fb_info *ovl)
+{
+ struct imx_ipu_fb_info *mxc_ovl = ovl->par;
+
+ if (!mxc_ovl->enabled)
+ return;
+
+ ipu_dp_disable_fg(mxc_ovl->dp);
+ ipu_wait_for_interrupt(451, 100);
+ ipu_idmac_disable_channel(mxc_ovl->ipu_ch);
+ ipu_dmfc_disable_channel(mxc_ovl->dmfc);
+ mxc_ovl->enabled = 0;
+}
Had better has a definition of ipu irq 451.
