"BCR reset" is redundant, and likely a mistake. Use the documented "wcss_q6_reset" instead. Drop ".wcss_q6_reset_required" from the descriptor, since all targets now need it. This changes the bindings expectations, however, it actually fixes the driver to consume the intended ones (qcom,q6v5.txt), which lists "wcss_q6_reset" and *not* "wcss_q6_bcr_reset" Fixes: 0af65b9b915e ("remoteproc: qcom: wcss: Add non pas wcss Q6 support for QCS404") Reviewed-by: Konrad Dybcio Signed-off-by: Alexandru Gagniuc Link: https://lore.kernel.org/r/20251208223315.3540680-1-mr.nuke.me@gmail.com Signed-off-by: Bjorn Andersson --- diff --git a/drivers/remoteproc/qcom_q6v5_wcss.c b/drivers/remoteproc/qcom_q6v5_wcss.c index c27200159a88..b391724cfd08 100644 --- a/drivers/remoteproc/qcom_q6v5_wcss.c +++ b/drivers/remoteproc/qcom_q6v5_wcss.c @@ -96,7 +96,6 @@ struct wcss_data { unsigned int crash_reason_smem; u32 version; bool aon_reset_required; - bool wcss_q6_reset_required; const char *ssr_name; const char *sysmon_name; int ssctl_id; @@ -134,7 +133,6 @@ struct q6v5_wcss { struct reset_control *wcss_aon_reset; struct reset_control *wcss_reset; struct reset_control *wcss_q6_reset; - struct reset_control *wcss_q6_bcr_reset; struct qcom_q6v5 q6v5; @@ -309,7 +307,7 @@ static int q6v5_wcss_qcs404_power_on(struct q6v5_wcss *wcss) return ret; /* Remove reset to the WCNSS QDSP6SS */ - reset_control_deassert(wcss->wcss_q6_bcr_reset); + reset_control_deassert(wcss->wcss_q6_reset); /* Enable Q6SSTOP_AHBFABRIC_CBCR clock */ ret = clk_prepare_enable(wcss->ahbfabric_cbcr_clk); @@ -803,19 +801,10 @@ static int q6v5_wcss_init_reset(struct q6v5_wcss *wcss, return PTR_ERR(wcss->wcss_reset); } - if (desc->wcss_q6_reset_required) { - wcss->wcss_q6_reset = devm_reset_control_get_exclusive(dev, "wcss_q6_reset"); - if (IS_ERR(wcss->wcss_q6_reset)) { - dev_err(wcss->dev, "unable to acquire wcss_q6_reset\n"); - return PTR_ERR(wcss->wcss_q6_reset); - } - } - - wcss->wcss_q6_bcr_reset = devm_reset_control_get_optional_exclusive(dev, - "wcss_q6_bcr_reset"); - if (IS_ERR(wcss->wcss_q6_bcr_reset)) { - dev_err(wcss->dev, "unable to acquire wcss_q6_bcr_reset\n"); - return PTR_ERR(wcss->wcss_q6_bcr_reset); + wcss->wcss_q6_reset = devm_reset_control_get_exclusive(dev, "wcss_q6_reset"); + if (IS_ERR(wcss->wcss_q6_reset)) { + dev_err(wcss->dev, "unable to acquire wcss_q6_reset\n"); + return PTR_ERR(wcss->wcss_q6_reset); } return 0; @@ -1062,7 +1051,6 @@ static const struct wcss_data wcss_ipq8074_res_init = { .firmware_name = "IPQ8074/q6_fw.mdt", .crash_reason_smem = WCSS_CRASH_REASON, .aon_reset_required = true, - .wcss_q6_reset_required = true, .ops = &q6v5_wcss_ipq8074_ops, .requires_force_stop = true, }; @@ -1072,7 +1060,6 @@ static const struct wcss_data wcss_qcs404_res_init = { .firmware_name = "wcnss.mdt", .version = WCSS_QCS404, .aon_reset_required = false, - .wcss_q6_reset_required = false, .ssr_name = "mpss", .sysmon_name = "wcnss", .ssctl_id = 0x12,
