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. Note that struct renesas_usbhs_driver_param has to use copied value because the driver has to set some members (e.g. buswait_bwait).

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.

2017-11-07USB: renesas_usbhs: Remove redundant license textGreg Kroah-Hartman1-10/+0
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.

2015-07-29usb: renesas_usbhs: Replace deprecated API of extconChanwoo Choi1-1/+1
This patch removes the deprecated API of extcon and then use the new extcon API with the unique id to indicate the each external connector (USB-HOST). - extcon_get_cable_state(*edev, char *) -> extcon_get_cable_state_(*edev, id) Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Felipe Balbi <balbi@ti.com> Cc: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Cc: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> Cc: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Cc: Peter Chen <peter.chen@freescale.com> Cc: Varka Bhadram <varkab@cdac.in> Cc: Takeshi Kihara <takeshi.kihara.df@renesas.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

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.

2015-03-13usb: renesas_usbhs: add support for USB-DMACYoshihiro Shimoda1-0/+19
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.

2015-01-13usb: renesas_usbhs: add OTG ID signal sensingSergei Shtylyov1-0/+17
On the Renesas R8A7791 SoC based boards there's MAX3355 USB OTG chip and mini-AB USB connector corresponding to USB port 0 driven either by EHCI/OHCI or Renesas USBHS gadget controller. And we'd like the host/gadget drivers to work based on the cable type connected. An 'extcon' driver for MAX3355 has been written, so we only need to bind to it via device tree which I'm doing in this patch. (Perhaps, it would also make sense to use OTG HNP when the USBHS host mode is active and a B-cable is connected but I don't have access to host-capable USBHS, so wouldn't be able to test it.)

There is a typo ("prove" instead of "probe") in the error message printed when the platform initialization fails. Replace that word with more fitting "init". Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
