2024-04-18usb: renesas_usbhs: Remove renesas_usbhs_get_info() wrapperGeert Uytterhoeven1-5/+0
The renesas_usbhs_get_info() wrapper was useful for legacy board code. Since commit 1fa59bda21c7fa36 ("ARM: shmobile: Remove legacy board code for Armadillo-800 EVA") in v4.3, it is no longer used outside the USBHS driver, and provides no added value over dev_get_platdata(), while obfuscating the real operation. Drop it, and replace it by dev_get_platdata() in its sole user.

2019-12-30usb: renesas_usbhs: Switch to GPIO descriptorLinus Walleij1-2/+0
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.

2017-11-04USB: add SPDX identifiers to all remaining files in drivers/usb/Greg Kroah-Hartman1-0/+1
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.

2015-12-15usb: renesas_usbhs: Modify pipe configurationYoshihiro Shimoda1-2/+16
The current code has info->bufnmb_last to calculate the BUFNMB bits of PIPEBUF register. However, since the bufnmb_last is initialized in the usbhs_pipe_init() only, this driver is possible to set unexpected value to the register if usb_ep_{enable,disable}() are called many times. So, this patch modifies the pipe configuration via struct renesas_usbhs_driver_param to simplify the code.

2015-03-13usb: renesas_usbhs: add support for USB-DMACYoshihiro Shimoda1-0/+2
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.
