This driver wasn't converted to the new clock framework (e038ed50a4a767add205094c035b6943e7b30140).
Signed-off-by: Javier Martin <[email protected]> --- This is broken in current stable 3.5 too. So it should be applied to both stable and 3.6. --- drivers/media/video/mx2_emmaprp.c | 27 ++++++++++++++++----------- 1 file changed, 16 insertions(+), 11 deletions(-) diff --git a/drivers/media/video/mx2_emmaprp.c b/drivers/media/video/mx2_emmaprp.c index 0bd5815..2614a89 100644 --- a/drivers/media/video/mx2_emmaprp.c +++ b/drivers/media/video/mx2_emmaprp.c @@ -209,7 +209,7 @@ struct emmaprp_dev { int irq_emma; void __iomem *base_emma; - struct clk *clk_emma; + struct clk *clk_emma_ahb, *clk_emma_ipg; struct resource *res_emma; struct v4l2_m2m_dev *m2m_dev; @@ -800,7 +800,8 @@ static int emmaprp_open(struct file *file) return ret; } - clk_enable(pcdev->clk_emma); + clk_prepare_enable(pcdev->clk_emma_ipg); + clk_prepare_enable(pcdev->clk_emma_ahb); ctx->q_data[V4L2_M2M_SRC].fmt = &formats[1]; ctx->q_data[V4L2_M2M_DST].fmt = &formats[0]; @@ -816,7 +817,8 @@ static int emmaprp_release(struct file *file) dprintk(pcdev, "Releasing instance %p\n", ctx); - clk_disable(pcdev->clk_emma); + clk_disable_unprepare(pcdev->clk_emma_ahb); + clk_disable_unprepare(pcdev->clk_emma_ipg); v4l2_m2m_ctx_release(ctx->m2m_ctx); kfree(ctx); @@ -876,9 +878,15 @@ static int emmaprp_probe(struct platform_device *pdev) spin_lock_init(&pcdev->irqlock); - pcdev->clk_emma = clk_get(&pdev->dev, NULL); - if (IS_ERR(pcdev->clk_emma)) { - ret = PTR_ERR(pcdev->clk_emma); + pcdev->clk_emma_ipg = devm_clk_get(&pdev->dev, "ipg"); + if (IS_ERR(pcdev->clk_emma_ipg)) { + ret = PTR_ERR(pcdev->clk_emma_ipg); + goto free_dev; + } + + pcdev->clk_emma_ahb = devm_clk_get(&pdev->dev, "ahb"); + if (IS_ERR(pcdev->clk_emma_ipg)) { + ret = PTR_ERR(pcdev->clk_emma_ahb); goto free_dev; } @@ -887,12 +895,12 @@ static int emmaprp_probe(struct platform_device *pdev) if (irq_emma < 0 || res_emma == NULL) { dev_err(&pdev->dev, "Missing platform resources data\n"); ret = -ENODEV; - goto free_clk; + goto free_dev; } ret = v4l2_device_register(&pdev->dev, &pcdev->v4l2_dev); if (ret) - goto free_clk; + goto free_dev; mutex_init(&pcdev->dev_mutex); @@ -965,8 +973,6 @@ rel_vdev: video_device_release(vfd); unreg_dev: v4l2_device_unregister(&pcdev->v4l2_dev); -free_clk: - clk_put(pcdev->clk_emma); free_dev: kfree(pcdev); @@ -983,7 +989,6 @@ static int emmaprp_remove(struct platform_device *pdev) v4l2_m2m_release(pcdev->m2m_dev); vb2_dma_contig_cleanup_ctx(pcdev->alloc_ctx); v4l2_device_unregister(&pcdev->v4l2_dev); - clk_put(pcdev->clk_emma); kfree(pcdev); return 0; -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
