2016-09-29usb: chipidea: Use extcon framework for ID and VBUS detectionSanchayan Maity
Rather than relying on special USB/PHY pins/registers use the generic extcon framework with its extcon-usb-gpio implementation to detect ID and VBUS changes. Signed-off-by: Sanchayan Maity <maitysanchayan@gmail.com> Signed-off-by: Stefan Agner <stefan.agner@toradex.com>

The USB charger functionality depends on functions provided by CONFIG_POWER_SUPPLY but this dependency is not forced through Kconfig. Don't compile the functionality in when CONFIG_POWER_SUPPLY is not set.

Add HSIC support for imx7d. We have not supported HSIC as system wakeup as well as HSIC remote wakeup function at DSM mode, since the 24M OSC can't be off and the SoC internal regulators can't be off at this mode, that will keep power consumption much higher.

2016-03-17usb: chipidea: add system interface for ttctrl.tthaPeter Chen
In chipidea IP RTL, there is a very limited design for siTD, the detail like below: There is no Max Packet Size at siTD, so it uses one constant for both Max Packet Size for packet and the packet size for the last transaction when considering schedule. If the ttctrl.ttha does not match against Hub Address field in siTD, this constant is 188 bytes, else this constant is 1023 bytes. If the ttctrl.ttha is non-zero value, RTL will use 188 as this constant, so it will lose the data if the packet size is larger than 188 bytes, eg, if we playback a wav which format is 48khz, 16 bits, 2 channels, the packet size will be 192bytes, but the controller will only send 188 bytes for this packet, the noise will be heared using USB audio card. The use case is single transaction, but higher frame rate. If the ttctr.ttha is zero value, we can send 1023 bytes within one transaction, but the controller will not accept the coming tranaction if it considers the schedule time is less than 1023 bytes. So the limitation is we can't schedule as many as transactions within frame. If the total bytes is already 256 bytes for previous transactions within frame, it can't accept another transaction. The use case is multiple transactions, but less frame rate.

It is better we disconnect (pulldown dp) host when the system enters suspend if the host did not suspend bus beforehand, it can avoid unnecessary udc suspend irq during usb enters suspend. This unexpected suspend irq occurs due to the udc still pulls up dp, but the host suspends bus due to it finds the device has disconnected. The device turns off high speed terminal will be considered a disconnection event from the host. It also fixes the bug ENGR00325724 describes.

2016-01-14usb: gadget: udc-core: independent registration of gadgets and gadget driversRuslan Bilovol
Change behavior during registration of gadgets and gadget drivers in udc-core. Instead of previous approach when for successful probe of usb gadget driver at least one usb gadget should be already registered use another one where gadget drivers and gadgets can be registered in udc-core independently. Independent registration of gadgets and gadget drivers is useful for built-in into kernel gadget and gadget driver case - because it's possible that gadget is really probed only on late_init stage (due to deferred probe) whereas gadget driver's probe is silently failed on module_init stage due to no any UDC added. Also it is useful for modules case - now there is no difference what module to insert first: gadget module or gadget driver one.

2016-01-14MLK-11891-1 usb: otg-fsm: allocate DMA buffer for host request flag separatelyLi Jun
HNP polling need a one byte buffer for usb control transfer via DMA read, currently using a data field in a structure for DMA buffer may cause cache incoherent issue, because the cache line for the DMA buffer also contains other data in this structure, while dma from device is outstanding, the access on other data in the same cache line will cause we get the old data before DMA. This patch change the host_request_flag to be a pointer, its memory will be allocated through kmalloc by controller driver, with this way, the DMA buffer can be properly aligned and padded.

The bulk queue tests are used to show 'best performance' for bulk transfer, we are often asked this question by users. The implementation is the same with iso test, that is queue request at interrupt completion, so we reuse the iso structures, and rename them as common one. It's result should be very close to IC simulation, in order to get that, the device side should also need to prepare enough queue.
