Right now we rely on video encoder/decoder selection happening in the dtb but, this goes against the remit of device tree which is supposed to describe hardware, not select functional logic in Linux drivers. Provide two strings in the venus resource structure enc_nodename and dec_nodename. When set the venus driver will create an OF entry in-memory consistent with: dec_nodename { compat = "video-decoder"; }; and/or enc_nodename { compat = "video-encoder"; }; This will allow us to reuse the existing driver scheme of relying on compat names maintaining compatibility with old dtb files. dec_nodename can be "video-decoder" or "video0" enc_nodename can be "video-encoder" or "video1" Signed-off-by: Bryan O'Donoghue --- drivers/media/platform/qcom/venus/core.c | 56 ++++++++++++++++++++++++++++++++ drivers/media/platform/qcom/venus/core.h | 2 ++ 2 files changed, 58 insertions(+) diff --git a/drivers/media/platform/qcom/venus/core.c b/drivers/media/platform/qcom/venus/core.c index 4e26b18790537885a77d66c1917a4e7a146eaf57..17506d547a6172b89acb77879337750c22f993cf 100644 --- a/drivers/media/platform/qcom/venus/core.c +++ b/drivers/media/platform/qcom/venus/core.c @@ -286,6 +286,36 @@ static irqreturn_t venus_isr_thread(int irq, void *dev_id) return ret; } +static int venus_add_video_core(struct device *dev, struct of_changeset *ocs, + const char *node_name, const char *compat) +{ + struct device_node *np, *enp; + int ret; + + if (!node_name) + return 0; + + enp = of_find_node_by_name(dev->of_node, node_name); + if (enp) { + of_node_put(enp); + return 0; + } + + np = of_changeset_create_node(ocs, dev->of_node, node_name); + if (!np) { + dev_err(dev, "Unable to create new node\n"); + return -ENODEV; + } + + ret = of_changeset_add_prop_string(ocs, np, "compatible", compat); + if (ret) + dev_err(dev, "unable to add %s\n", compat); + + of_node_put(np); + + return ret; +} + static int venus_probe(struct platform_device *pdev) { struct device *dev = &pdev->dev; @@ -365,6 +395,32 @@ static int venus_probe(struct platform_device *pdev) if (ret < 0) goto err_runtime_disable; + if (core->res->dec_nodename || core->res->enc_nodename) { + struct of_changeset *ocs; + + ocs = devm_kmalloc(dev, sizeof(*ocs), GFP_KERNEL); + if (!ocs) { + ret = -ENOMEM; + goto err_runtime_disable; + } + + of_changeset_init(ocs); + + ret = venus_add_video_core(dev, ocs, core->res->dec_nodename, "venus-decoder"); + if (ret) + goto err_runtime_disable; + + ret = venus_add_video_core(dev, ocs, core->res->enc_nodename, "venus-encoder"); + if (ret) + goto err_runtime_disable; + + ret = of_changeset_apply(ocs); + if (ret) { + dev_err(dev, "applying changeset fail ret %d\n", ret); + goto err_runtime_disable; + } + } + ret = of_platform_populate(dev->of_node, NULL, NULL, dev); if (ret) goto err_runtime_disable; diff --git a/drivers/media/platform/qcom/venus/core.h b/drivers/media/platform/qcom/venus/core.h index 27784fd7082c321222b23ca4b2902a04c49e19ca..4ce98a3ef186823a57ac40e2e8e42b08fafed575 100644 --- a/drivers/media/platform/qcom/venus/core.h +++ b/drivers/media/platform/qcom/venus/core.h @@ -90,6 +90,8 @@ struct venus_resources { u32 cp_nonpixel_start; u32 cp_nonpixel_size; const char *fwname; + const char *enc_nodename; + const char *dec_nodename; }; enum venus_fmt {
