usb: dwc2: fix STM32F7 USB OTG HS compatible

2018-03-05T08:43:57Z

This patch fixes compatible for STM32F7 USB OTG HS and consistently rename dw2_set_params function. The v2 former patch [1] had been acked by Paul Young, but v1 was merged.

usb: dwc2: Fix TxFIFOn sizes and total TxFIFO size issues

2017-12-11T10:35:37Z

In host mode reading from DPTXSIZn returning invalid value in dwc2_check_param_tx_fifo_sizes function. In total TxFIFO size calculations unnecessarily reducing by ep_info. hw->total_fifo_size can be fully allocated for FIFO's. Added num_dev_in_eps member in dwc2_hw_params structure to save number of IN EPs. Added g_tx_fifo_size array in dwc2_hw_params structure to store power on reset values of DPTXSIZn registers in forced device mode. Updated dwc2_hsotg_tx_fifo_count() function to get TxFIFO count from num_dev_in_eps. Updated dwc2_get_dev_hwparams() function to store DPTXFSIZn in g_tx_fifo_size array. dwc2_get_host/dev_hwparams() functions call moved after num_dev_in_eps set from hwcfg4. Modified dwc2_check_param_tx_fifo_sizes() function to check TxFIFOn sizes based on g_tx_fifo_size array. Removed ep_info subtraction during calculation of tx_addr_max in dwc2_hsotg_tx_fifo_total_depth() function. Also removed dwc2_hsotg_ep_info_size() function as no more need.

USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02Z

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

usb: dwc2: disable erroneous overcurrent condition

2017-10-19T07:38:14Z

For the case where an external VBUS is used, we should enable the external VBUS comparator in the driver. This would prevent an unnecessary overcurrent error which would then disable the host port. This patch uses the standard 'disable-over-current' binding to allow of the option of disabling the over-current condition.

usb: dwc2: add support for the DWC2 controller on Meson8 SoCs

2017-06-02T08:27:36Z

USB support in the Meson8 SoCs is provided by a DWC2 controller which works with the same settings as Meson8b and GXBB. Using the generic "snps,dwc2" binding results in an endless stream of "Overcurrent change detected" messages. Acked-by: Rob Herring Signed-off-by: Martin Blumenstingl Signed-off-by: Felipe Balbi

usb: dwc2: Add support for STM32F429/439/469 USB OTG HS/FS in FS mode (internal PHY)

2017-04-11T07:58:17Z

This patch introduces a new parameter to activate USB OTG HS/FS core embedded phy transceiver. The STM32F4x9 SoC uses the GGPIO register to enable the transceiver. Also add the dwc2_set_params function for stm32f4 otg fs. Acked-by: John Youn Signed-off-by: Bruno Herrera Signed-off-by: Felipe Balbi

usb: dwc2: gadget: Add checking for g-tx-fifo-size parameter

2017-01-24T14:19:11Z

Add dwc2_check_param_tx_fifo_sizes function which validates the members of g_tx_fifo_size array and sets to average or default values if it is needed. Cc: Stefan Wahren Signed-off-by: Sevak Arakelyan Signed-off-by: John Youn Signed-off-by: Felipe Balbi

usb: dwc2: gadget: Set TX FIFO depths to calculated defaults

2017-01-24T14:19:11Z

Remove legacy DWC2_G_P_LEGACY_TX_FIFO_SIZE array for TX FIFOs. Update dwc2_set_param_tx_fifo_sizes function to calculate and assign default average FIFO depth to each member of g_tx_fifo_size array. Total FIFO size, EP Info block's size, FIFO operation mode and device operation mode are taken into consideration during the calculation.

usb: dwc2: Add a quirk to allow speed negotiation for Hisilicon Hi6220

2017-01-24T14:19:10Z

The Hi6220's usb controller is limited in that it does not support "Split Transactions", so it does not support communicating with low-speed and full-speed devices behind a high-speed hub. Thus it requires a quirk so that we can manually drop the usb speed when low/full-speed are attached, and bump back to high speed when they are removed.
