Signed-off-by: Kever Yang <kever.yang@...k-chips.com> Acked-by: Paul Zimmerman <paulz@...opsys.com> --- Changes in v5: - max_transfer_size change to 65535 to met the requirement of header file Changes in v4: - max_transfer_size change to 65536, this should be enough for most transfer, the hardware auto-detect will set this to 0x7ffff which may make dma_alloc_coherent fail when non-dword aligned buf from driver like usbnet happen. Changes in v3: None Changes in v2: - set most parameters as driver auto-detect drivers/usb/dwc2/platform.c | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) diff --git a/drivers/usb/dwc2/platform.c b/drivers/usb/dwc2/platform.c index a10e7a3..2f859bd 100644 --- a/drivers/usb/dwc2/platform.c +++ b/drivers/usb/dwc2/platform.c @@ -75,6 +75,34 @@ static const struct dwc2_core_params params_bcm2835 = { .uframe_sched = 0, }; +static const struct dwc2_core_params params_rk3066 = { + .otg_cap = 2, /* non-HNP/non-SRP */ + .otg_ver = -1, + .dma_enable = -1, + .dma_desc_enable = 0, + .speed = -1, + .enable_dynamic_fifo = 1, + .en_multiple_tx_fifo = -1, + .host_rx_fifo_size = 520, /* 520 DWORDs */ + .host_nperio_tx_fifo_size = 128, /* 128 DWORDs */ + .host_perio_tx_fifo_size = 256, /* 256 DWORDs */ + .max_transfer_size = 65535, + .max_packet_count = -1, + .host_channels = -1, + .phy_type = -1, + .phy_utmi_width = -1, + .phy_ulpi_ddr = -1, + .phy_ulpi_ext_vbus = -1, + .i2c_enable = -1, + .ulpi_fs_ls = -1, + .host_support_fs_ls_low_power = -1, + .host_ls_low_power_phy_clk = -1, + .ts_dline = -1, + .reload_ctl = -1, + .ahbcfg = 0x7, /* INCR16 */ + .uframe_sched = -1, +}; + /** * dwc2_driver_remove() - Called when the DWC_otg core is unregistered with the * DWC_otg driver @@ -97,6 +125,7 @@ static int dwc2_driver_remove(struct platform_device *dev) static const struct of_device_id dwc2_of_match_table[] = { { .compatible = "brcm,bcm2835-usb", .data = ¶ms_bcm2835 }, + { .compatible = "rockchip,rk3066-usb", .data = ¶ms_rk3066 }, { .compatible = "snps,dwc2", .data = NULL }, {}, }; -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
