Since IPQ5424 has only one instance, both the LLCC and LLCC_BROADCAST points to the same register space. Signed-off-by: Varadarajan Narayanan --- v2: Use 'true/false' instead of '1/0' for boolean variables. Add 'no_broadcast_register' to qcom_llcc_config structure to identify SoC without LLCC_BROADCAST register space instead of using 'num_banks'. --- drivers/soc/qcom/llcc-qcom.c | 58 ++++++++++++++++++++++++++++++++++-- 1 file changed, 56 insertions(+), 2 deletions(-) diff --git a/drivers/soc/qcom/llcc-qcom.c b/drivers/soc/qcom/llcc-qcom.c index a470285f54a8..f34d65fdd185 100644 --- a/drivers/soc/qcom/llcc-qcom.c +++ b/drivers/soc/qcom/llcc-qcom.c @@ -140,6 +140,7 @@ struct qcom_llcc_config { bool need_llcc_cfg; bool no_edac; bool irq_configured; + bool no_broadcast_register; }; =20 struct qcom_sct_config { @@ -152,6 +153,38 @@ enum llcc_reg_offset { LLCC_COMMON_STATUS0, }; =20 +static const struct llcc_slice_config ipq5424_data[] =3D { + { + .usecase_id =3D LLCC_CPUSS, + .slice_id =3D 1, + .max_cap =3D 768, + .priority =3D 1, + .bonus_ways =3D 0xFFFF, + .retain_on_pc =3D true, + .activate_on_init =3D true, + .write_scid_cacheable_en =3D true, + .stale_en =3D true, + .stale_cap_en =3D true, + .alloc_oneway_en =3D true, + .ovcap_en =3D true, + .ovcap_prio =3D true, + .vict_prio =3D true, + }, + { + .usecase_id =3D LLCC_VIDSC0, + .slice_id =3D 2, + .max_cap =3D 256, + .priority =3D 2, + .fixed_size =3D true, + .bonus_ways =3D 0xF000, + .retain_on_pc =3D true, + .activate_on_init =3D true, + .write_scid_cacheable_en =3D true, + .stale_en =3D true, + .stale_cap_en =3D true, + }, +}; + static const struct llcc_slice_config sa8775p_data[] =3D { { .usecase_id =3D LLCC_CPUSS, @@ -2677,6 +2710,17 @@ static const struct qcom_llcc_config qdu1000_cfg[] = =3D { }, }; =20 +static const struct qcom_llcc_config ipq5424_cfg[] =3D { + { + .sct_data =3D ipq5424_data, + .size =3D ARRAY_SIZE(ipq5424_data), + .need_llcc_cfg =3D true, + .reg_offset =3D llcc_v2_1_reg_offset, + .edac_reg_offset =3D &llcc_v2_1_edac_reg_offset, + .no_broadcast_register =3D true, + }, +}; + static const struct qcom_llcc_config sa8775p_cfg[] =3D { { .sct_data =3D sa8775p_data, @@ -2834,6 +2878,11 @@ static const struct qcom_sct_config qdu1000_cfgs =3D= { .num_config =3D ARRAY_SIZE(qdu1000_cfg), }; =20 +static const struct qcom_sct_config ipq5424_cfgs =3D { + .llcc_config =3D ipq5424_cfg, + .num_config =3D ARRAY_SIZE(ipq5424_cfg), +}; + static const struct qcom_sct_config sa8775p_cfgs =3D { .llcc_config =3D sa8775p_cfg, .num_config =3D ARRAY_SIZE(sa8775p_cfg), @@ -3412,8 +3461,12 @@ static int qcom_llcc_probe(struct platform_device *p= dev) =20 drv_data->bcast_regmap =3D qcom_llcc_init_mmio(pdev, i, "llcc_broadcast_b= ase"); if (IS_ERR(drv_data->bcast_regmap)) { - ret =3D PTR_ERR(drv_data->bcast_regmap); - goto err; + if (cfg->no_broadcast_register) { + drv_data->bcast_regmap =3D regmap; + } else { + ret =3D PTR_ERR(drv_data->bcast_regmap); + goto err; + } } =20 /* Extract version of the IP */ @@ -3485,6 +3538,7 @@ static int qcom_llcc_probe(struct platform_device *pd= ev) =20 static const struct of_device_id qcom_llcc_of_match[] =3D { { .compatible =3D "qcom,qdu1000-llcc", .data =3D &qdu1000_cfgs}, + { .compatible =3D "qcom,ipq5424-llcc", .data =3D &ipq5424_cfgs}, { .compatible =3D "qcom,sa8775p-llcc", .data =3D &sa8775p_cfgs }, { .compatible =3D "qcom,sc7180-llcc", .data =3D &sc7180_cfgs }, { .compatible =3D "qcom,sc7280-llcc", .data =3D &sc7280_cfgs }, --=20 2.34.1
