Dear Uwe,
which repository should I search 90026c8c823bff54172eab33a5e7fcecfd3df635
in? I have not found it in git.pengutronix.de/git/imx/linux-2.6.git nor in
vanilla sources.
regards Jan

thank you for answer. You are right I give no memory to camera
device in mach-imx27ipcam.c. I have tried to do it in same way as it
is in mach-pcm037.c but no success. Here is my init function
static int __init mx27ipcam_camera_init(void) {
int dma, ret = -ENOMEM;
struct platform_device *pdev;
printk("MX2 camera initialization.\n");
pdev = imx27_add_mx2_camera(&mx27ipcam_camera);
if (IS_ERR(pdev)) {
printk("pdev error\n");
return PTR_ERR(pdev);
}
dma = dma_declare_coherent_memory(&pdev->dev,
mx2_camera_base, mx2_camera_base,
MX2_CAMERA_BUF_SIZE,
DMA_MEMORY_MAP | DMA_MEMORY_EXCLUSIVE);
if (!(dma & DMA_MEMORY_MAP))
goto err;
ret = platform_device_add(pdev);
if (ret) {
printk("platform_device_add error\n");
err:
platform_device_put(pdev);
}
return ret;
}
and you also have a reserve callback? See commit
90026c8c823bff54172eab33a5e7fcecfd3df635 for all details.
Best regards
Uwe
