* usb: renesas_usbhs: Use platform_get_irq() to get the interruptLad Prabhakar2021-12-211-1/+0
| | | | | | | | | | | | | | | | | | | | platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq(). Drop irqflags member from struct usbhs_priv as this driver is used by two non DT users sh7757lcr and ecovec24 which do not pass IORESOURCE_IRQ_SHAREABLE as part of their pdata. Along this drop the IRQF_SHARED flag handling in the code.

* | usb: renesas_usbhs: add suspend event support in gadget modeVeeraiyan Chidambaram2019-10-041-1/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When R-Car Gen3 USB 2.0 is in Gadget mode, if host is detached an interrupt will be generated and Suspended state bit is set in interrupt status register. Interrupt handler will call driver->suspend(composite_suspend) if suspended state bit is set. composite_suspend will call ffs_func_suspend which will post FUNCTIONFS_SUSPEND and will be consumed by user space application via /dev/ep0. To be able to detect host detach, extend the DVSQ_MASK to cover the Suspended bit of the DVSQ[2:0] bitfield from the Interrupt Status Register 0 (INTSTS0) register and perform appropriate action in the DVST interrupt handler (usbhsg_irq_dev_state). Without this commit, disconnection of the phone from R-Car-H3 ES2.0 Salvator-X CN9 port is not recognized and reverse role switch does not happen. If phone is connected again it does not enumerate. With this commit, disconnection will be recognized and reverse role switch will happen by a user space application. If phone is connected again it will enumerate properly and will become visible in the output of 'lsusb'.

* usb: renesas_usbhs: Use struct platform_callback pointerYoshihiro Shimoda2019-06-261-1/+1
| | | | | | | | | | | | 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).

* usb: renesas_usbhs: Use renesas_usbhs_platform_info on of_device_id.dataYoshihiro Shimoda2019-06-261-5/+0
| | | | | | | | | | | | | | | | | 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.

* USB: renesas_usbhs: Remove redundant license textGreg Kroah-Hartman2017-11-071-10/+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.

| | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | spin lock was very effective while doing 1 packet send/recv on current renesas_usbhs driver. But this lock is enough only - modify packet/pipe link - modify interrpt mask - modify fifo access This patch shrink spin lock area Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* usb: renesas_usbhs: divide data transfer functionsKuninori Morimoto2011-06-071-1/+0
| | | | | | | | | | | | DMAEngine will be supported to this driver in the future. Then, both PIO and DMA data transfer method should be supported. But, the transfer function can returns the result immediately in PIO version, but it can't in DMA version. This patch divides data transfer functions into top/bottom half in preparation for DMAEngine support.

* usb: renesas_usbhs: fifo became independent from pipe.Kuninori Morimoto2011-06-071-0/+1
| | | | | | | | | | | Current renesas_usbhs has PIO data transfer mode which controls CFIFO. And it was implemented in pipe.c. But, fifo control method needs more flexible implementation to support DMAEngine. This patch create fifo.c, and it became independent from pipe.c.

* usb: renesas_usbhs: add autonomy modeKuninori Morimoto2011-04-291-0/+3
| | | | | | | | | | | | | | | Current renesas_usbhs was designed to save power when USB is not connected. And it assumed platform uses callback to notify connection/disconnection by external interrupt. But some SuperH / platform board doesn't have such feature. This patch adds autonomy mode which detect USB connection/disconnection by internal interrupt. But power will be always ON when autonomy mode is selected.
