From 2538f0ee8a2920d58812687e84c854b4a9882013 Mon Sep 17 00:00:00 2001 From: JC Kuo Date: Sat, 5 Oct 2019 00:29:01 +0800 Subject: [PATCH] usb: host: xhci-tegra: Add Tegra194 XHCI support This commit adds Tegra194 XUSB host mode controller support. This is very similar to the existing Tegra124/Tegra210/Tegra186 XHCI, except 1. the number of ports and PHYs differs 2. the IPFS wrapper being removed 3. mailbox registers address changes Signed-off-by: JC Kuo Link: https://lore.kernel.org/r/20191004162906.4818-3-jckuo@nvidia.com Signed-off-by: Greg Kroah-Hartman --- drivers/usb/host/xhci-tegra.c | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) diff --git a/drivers/usb/host/xhci-tegra.c b/drivers/usb/host/xhci-tegra.c index 9e78d8120a8c..540b47a99824 100644 --- a/drivers/usb/host/xhci-tegra.c +++ b/drivers/usb/host/xhci-tegra.c @@ -1459,10 +1459,40 @@ static const struct tegra_xusb_soc tegra186_soc = { }, }; +static const char * const tegra194_supply_names[] = { +}; + +static const struct tegra_xusb_phy_type tegra194_phy_types[] = { + { .name = "usb3", .num = 4, }, + { .name = "usb2", .num = 4, }, +}; + +static const struct tegra_xusb_soc tegra194_soc = { + .firmware = "nvidia/tegra194/xusb.bin", + .supply_names = tegra194_supply_names, + .num_supplies = ARRAY_SIZE(tegra194_supply_names), + .phy_types = tegra194_phy_types, + .num_types = ARRAY_SIZE(tegra194_phy_types), + .ports = { + .usb3 = { .offset = 0, .count = 4, }, + .usb2 = { .offset = 4, .count = 4, }, + }, + .scale_ss_clock = false, + .has_ipfs = false, + .mbox = { + .cmd = 0x68, + .data_in = 0x6c, + .data_out = 0x70, + .owner = 0x74, + }, +}; +MODULE_FIRMWARE("nvidia/tegra194/xusb.bin"); + static const struct of_device_id tegra_xusb_of_match[] = { { .compatible = "nvidia,tegra124-xusb", .data = &tegra124_soc }, { .compatible = "nvidia,tegra210-xusb", .data = &tegra210_soc }, { .compatible = "nvidia,tegra186-xusb", .data = &tegra186_soc }, + { .compatible = "nvidia,tegra194-xusb", .data = &tegra194_soc }, { }, }; MODULE_DEVICE_TABLE(of, tegra_xusb_of_match);
