From aac426562f568520b674f0d5ae3929977be9f1c0 Mon Sep 17 00:00:00 2001 From: Jarvis Jiang Date: Thu, 8 Apr 2021 02:55:24 -0700 Subject: [PATCH] bus: mhi: pci_generic: Introduce Foxconn T99W175 support Add support for T99W175 modems, this modem series is based on SDX55 qcom chip. The modem is mainly based on MBIM protocol for both the data and control path. This patch adds support for below modems: - T99W175(based on sdx55), Both for eSIM and Non-eSIM - DW5930e(based on sdx55), With eSIM, It's also T99W175 - DW5930e(based on sdx55), Non-eSIM, It's also T99W175 This patch was tested with Ubuntu 20.04 X86_64 PC as host Signed-off-by: Jarvis Jiang Reviewed-by: Loic Poulain Reviewed-by: Manivannan Sadhasivam Link: https://lore.kernel.org/r/20210408095524.3559-1-jarvis.w.jiang@gmail.com Signed-off-by: Manivannan Sadhasivam --- drivers/bus/mhi/pci_generic.c | 47 +++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) diff --git a/drivers/bus/mhi/pci_generic.c b/drivers/bus/mhi/pci_generic.c index aa8f8d541371..8f715519ba08 100644 --- a/drivers/bus/mhi/pci_generic.c +++ b/drivers/bus/mhi/pci_generic.c @@ -304,6 +304,44 @@ static const struct mhi_pci_dev_info mhi_quectel_em1xx_info = { .dma_data_width = 32 }; +static const struct mhi_channel_config mhi_foxconn_sdx55_channels[] = { + MHI_CHANNEL_CONFIG_UL(0, "LOOPBACK", 32, 0), + MHI_CHANNEL_CONFIG_DL(1, "LOOPBACK", 32, 0), + MHI_CHANNEL_CONFIG_UL(4, "DIAG", 32, 1), + MHI_CHANNEL_CONFIG_DL(5, "DIAG", 32, 1), + MHI_CHANNEL_CONFIG_UL(12, "MBIM", 32, 0), + MHI_CHANNEL_CONFIG_DL(13, "MBIM", 32, 0), + MHI_CHANNEL_CONFIG_UL(32, "AT", 32, 0), + MHI_CHANNEL_CONFIG_DL(33, "AT", 32, 0), + MHI_CHANNEL_CONFIG_HW_UL(100, "IP_HW0_MBIM", 128, 2), + MHI_CHANNEL_CONFIG_HW_DL(101, "IP_HW0_MBIM", 128, 3), +}; + +static struct mhi_event_config mhi_foxconn_sdx55_events[] = { + MHI_EVENT_CONFIG_CTRL(0, 128), + MHI_EVENT_CONFIG_DATA(1, 128), + MHI_EVENT_CONFIG_HW_DATA(2, 1024, 100), + MHI_EVENT_CONFIG_HW_DATA(3, 1024, 101) +}; + +static struct mhi_controller_config modem_foxconn_sdx55_config = { + .max_channels = 128, + .timeout_ms = 20000, + .num_channels = ARRAY_SIZE(mhi_foxconn_sdx55_channels), + .ch_cfg = mhi_foxconn_sdx55_channels, + .num_events = ARRAY_SIZE(mhi_foxconn_sdx55_events), + .event_cfg = mhi_foxconn_sdx55_events, +}; + +static const struct mhi_pci_dev_info mhi_foxconn_sdx55_info = { + .name = "foxconn-sdx55", + .fw = "qcom/sdx55m/sbl1.mbn", + .edl = "qcom/sdx55m/edl.mbn", + .config = &modem_foxconn_sdx55_config, + .bar_num = MHI_PCI_DEFAULT_BAR_NUM, + .dma_data_width = 32 +}; + static const struct pci_device_id mhi_pci_id_table[] = { { PCI_DEVICE(PCI_VENDOR_ID_QCOM, 0x0306), .driver_data = (kernel_ulong_t) &mhi_qcom_sdx55_info }, @@ -315,6 +353,15 @@ static const struct pci_device_id mhi_pci_id_table[] = { .driver_data = (kernel_ulong_t) &mhi_quectel_em1xx_info }, { PCI_DEVICE(PCI_VENDOR_ID_QCOM, 0x0308), .driver_data = (kernel_ulong_t) &mhi_qcom_sdx65_info }, + /* T99W175 (sdx55), Both for eSIM and Non-eSIM */ + { PCI_DEVICE(PCI_VENDOR_ID_FOXCONN, 0xe0ab), + .driver_data = (kernel_ulong_t) &mhi_foxconn_sdx55_info }, + /* DW5930e (sdx55), With eSIM, It's also T99W175 */ + { PCI_DEVICE(PCI_VENDOR_ID_FOXCONN, 0xe0b0), + .driver_data = (kernel_ulong_t) &mhi_foxconn_sdx55_info }, + /* DW5930e (sdx55), Non-eSIM, It's also T99W175 */ + { PCI_DEVICE(PCI_VENDOR_ID_FOXCONN, 0xe0b1), + .driver_data = (kernel_ulong_t) &mhi_foxconn_sdx55_info }, { } }; MODULE_DEVICE_TABLE(pci, mhi_pci_id_table);
