* usb: ehci: pass full speed devices to companion controllerPeter Mamonov2017-01-301-6/+21
| | | | | | | | | | | | | | | According to the "Enhanced Host Controller Interface Specification for Universal Serial Bus" after a USB port reset the EHCI Driver checks the PortEnable bit in the PORTSC register. If set to a one, the connected device is a high-speed device [...]. At the time the EHCI Driver receives the port reset and enable request the LineStatus bits might indicate a low-speed device. Additionally, when the port reset process is complete, the PortEnable field may indicate that a full-speed device is attached. In either case the EHCI driver sets the PortOwner bit in the PORTSC register to a one to release port ownership to a companion host controller.

* of_path: only handle no driver for device if it is on a busIan Abbott2017-01-131-1/+1
| | | | | | | | | | This fixes a regression in __of_find_path() for flash devices created by the cadence-quadspi driver, which do not have 'dev->driver' set. Such devices do not have 'dev->bus' set either, so we can use that to qualify the existing test. Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * i.MX: esdhc: Request "per" clock explicitlyAndrey Smirnov2017-01-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Calling clk_get() with NULL as the second argument will give us "ipg" clock as a result. The actual clock feeding into the peripheral is "per" and, depending on the SoC, "ipg" and "per" may be separated by a clock divider, so querying "ipg"'s rate may not result in rate that does not represent the actual peripheral clock rate. Change the code to request "per" as our peripheral clock to avoid aforementioned problem. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | CPU type is not a reliable indicator of the underlying type of IP core used, since there's no 1:1 mapping between the two. As example of one such violation consider Vybrid SoC which contains IP block from i.MX53. Instead port feature flags from corresponding Linux kernel driver and use the ones that are relevant.

Instead, read only the data we actually need and speed up attachment of UBI devices by potentially making use of reading subpages if the NAND driver supports it. Since the VID header may be at offset vid_hdr_shift in the page and we can only read from the beginning of a page we have to add that offset to the read size.
