* sunxi: ohci: Add ohci usb host controller supportHans de Goede2015-05-14-1/+4
| | | | | | | | | | | | | This commit adds support for the OHCI companion controller, which makes usb-1 devices directly plugged into to usb root port work. Note for now this switches usb-keyboard support for sunxi back from int-queue support to the old interrupt polling method. Adding int-queue support to the ohci code and switching back to int-queue support is in the works.

* dm: usb: Add support for companion controllersHans de Goede2015-05-14-0/+3
| | | | | | | | | | | | | | USB companion controllers must be scanned after the main controller has been scanned, so that any devices which the main controller which to hand over to the companion have actually been handed over before we scan the companion. As there are no guarantees that this will magically happen in the right order, split the scanning of the buses in 2 phases, first main controllers, and then companion controllers.

* dm: usb: Add support for interrupt queues to the dm usb codeHans de Goede2015-05-14-1/+47
| | | | | | | | | | | | | | | Interrupt endpoints typically are polled for a long time by the usb controller before they return anything, so calls to submit_int_msg() can take a long time to complete this. To avoid this the u-boot code has the an interrupt queue mechanism / API, add support for this to the driver-model usb code and implement it for the dm ehci code.

| * ARM: tegra: CONFIG_{SYS_, }LOAD{_, }ADDR rationalizationStephen Warren2015-05-13-20/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As best I can tell, CONFIG_SYS_LOAD_ADDR and CONFIG_LOADADDR/$loadaddr serve essentially the same purpose. Roughly, if a command takes a load address, then CONFIG_SYS_LOAD_ADDR or $loadaddr (or both) are the default if the command-line does not specify the address. Different U-Boot commands are inconsistent re: which of the two default values they use. As such, set the two to the same value, and move the logic that does this into tegra-common-post.h so it's not duplicated. A number of other non- Tegra boards do this too. The values chosen for these macros are no longer consistent with anything in MEM_LAYOUT_ENV_SETTINGS. Regain consistency by setting $kernel_addr_r to CONFIG_LOADADDR. Older scripts tend to use $loadaddr for the default kernel load address, whereas newer scripts and features tend to use $kernel_addr_r, along with other variables for other purposes such as DTBs and initrds. Hence, it's logical they should share the same value. I had originally thought to make the $kernel_addr_r and CONFIG_LOADADDR have different values. This would guarantee no interference if a script used the two variables for different purposes. However, that scenario is unlikely given the semantic meaning associated with the two variables. The lowest available value is 0x90200000; see comments for MEM_LAYOUT_ENV_SETTINGS in tegra30-common-post.h for details. However, that value would be problematic for a script that loaded a raw zImage to $loadaddr, since it's more than 128MB beyond the start of SDRAM, which would interfere with the kernel's CONFIG_AUTO_ZRELADDR. So, let's not do that. The only potential fallout I could foresee from this patch is if someone has a script that loads the kernel to $loadaddr, but some other file (DTB, initrd) to a hard-coded address that the new value of $loadaddr interferes with. This seems unlikely. A user should not do that; they should either hard-code all load addresses, or use U-Boot-supplied variables for all load addresses. Equally, any fallout due to this change is trivial to fix; simply modify the load addresses in that script.

In very small applications only we use the simple-framebuffer. So we have 2 use-cases: - device operating on drm-driver (let simplefb node disabled) - device operating on simplefb-driver (activate simplefb node and reserve mem) The decision is made by means of "simplefb" environment variable. simplefb = 0 we don't enable the (maybe) existing simplefb node and all the rest around display is up to the linux-kernel. We just disable the backlight, beceause we do not want see the flicker during take over of drm-driver. simplefb = 1 we enable the (maybe) existing simplefb node and reserve framebuffers size in memory.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we copy over a number of usb_device values stored in the on stack struct usb_device probed in usb_scan_device() to the final driver-model managed struct usb_device in usb_child_pre_probe() through usb_device_platdata, and then call usb_select_config() to fill in the rest. There are 3 problems with this approach: 1) It does not fill in enough fields before calling usb_select_config(), specifically it does not fill in ep0's maxpacketsize causing a div by zero exception in the ehci driver. 2) It unnecessarily redoes a number of usb requests making usb probing slower 3) Calling usb_select_config() a second time fails on some usb-1 devices plugged into usb-2 hubs, causing u-boot to not recognize these devices. This commit fixes these issues by removing (*) the usb_select_config() call from usb_child_pre_probe(), and instead of copying over things field by field through usb_device_platdata, store a pointer to the in stack usb_device (which is still valid when usb_child_pre_probe() gets called) and copy over the entire struct. *) Except for devices which are explictly instantiated through device-tree rather then discovered through usb_scan_device() such as emulated usb devices in the sandbox.
