2019-12-30usb: renesas_usbhs: Switch to GPIO descriptorLinus Walleij1-13/+9
The Renesas USBHS driver includes a bit of surplus headers and uses the old GPIO API so let's switch it to use the GPIO descriptor. I noticed that the enable_gpio inside renesas_usbhs_driver_param isn't really referenced anywhere, and it is also the wrong type (u32) so let's just delete it and use a local variable instead.

2019-06-26usb: renesas_usbhs: Use struct platform_callback pointerYoshihiro Shimoda1-4/+4
Now the driver fixes the issue of the commit 482982062f1b ("usb: gadget: renesas_usbhs: bugfix: don't modify platform data") by using usbhs_mod_info.get_vbus, this patches uses the pointer instead of copied value to avoid redundancy.

2019-06-26usb: renesas_usbhs: Use renesas_usbhs_platform_info on of_device_id.dataYoshihiro Shimoda1-77/+16
In device tree environment, the previous code allocates renesas_usbhs_platform_info by using devm_kzalloc() and then copies usbhs_of_data to the allocated memory. This reason is some values (e.g. .platform_callback.get_vbus) are overwritten by the driver, but the of_device_id.data is "const". Now the driver doesn't have such a code, so this patch uses renesas_usbhs_platform_info on of_device_id.data. Note that the previous code set the pdev->dev.platform_data pointer even if device tree environment, but the value is not used. So, this patch also remove such a code.

The very old commit 482982062f1b ("usb: gadget: renesas_usbhs: bugfix: don't modify platform data") changed to use copied whole structures values to fix the "hung-up" issue. However, we also can fix the issue if the driver copies the get_vbus function pointer to the driver's value.

Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

2015-05-26usb: renesas_usbhs: Change USBHS_TYPE_R8A779x to USBHS_TYPE_RCAR_GEN2Yoshihiro Shimoda1-11/+4
Since the HSUSB controllers of R-Car Gen2 are the same specification (they have 16 pipes and usb-dmac), this patch changes USBHS_TYPE_R8A7790 and USBHS_TYPE_R8A7791 to USBHS_TYPE_RCAR_GEN2. Signed-off-by: Yoshihiro Shimoda <[email protected]> Signed-off-by: Felipe Balbi <[email protected]>

Some Renesas SoCs have the USB-DMAC. It is able to terminate transfers when a short packet is received, even if less bytes than the transfer counter size have been received. Also, it is able to send a short packet even if the packet size is not multiples of 8bytes. Since the previous code has used the interruption of USBHS controller when receiving packets even if this driver has used a dmac, a lot of interruptions has happened. This patch will reduce such interruptions. This patch allows to use the USB-DMAC on R-Car H2 and M2.
