2013-07-29usb: dwc3: gadget: drop dwc3 manual phy controlFelipe Balbi1-61/+0
Recent versions of the core, can suspend and resume the PHYs automatically, so we don't need to fiddle with dwc3's Global PHY registers at all. On versions prior to 1.94a this patch will mean that we will never ask dwc3 to suspend the PHY. This is an acceptable behavior or such old versions of the core, specially considering that the only chip known to have a version prior to 1.94a was OMAP5 ES1.0 and that's not supported in mainline kernel, because it was just a test spin of OMAP5.

2013-07-29usb: dwc3: adapt to use dr_mode device tree helperRuchika Kharwar3-43/+43
This patch adapts the dwc3 to use the device tree helper "of_usb_get_dr_mode" for the mode of operation of the dwc3 instance being probed.

2013-07-29usb: dwc3: core: switch to snps,dwc3Felipe Balbi3-3/+6
all other drivers using Synopsys IPs with DT have a compatible of snps,$driver, in order to add consistency, we are switching over to snps,dwc3 but keeping synopsys,dwc3 in the core driver to maintain backwards compatibility. New DTS bindings should NOT use synopsys,dwc3. Signed-off-by: Felipe Balbi <balbi@ti.com>
2013-07-29usb: dwc3: make maximum-speed a per-instance attributeFelipe Balbi3-18/+30
in order to allow different instances of the core work in different maximum speeds, we will move the maximum_speed module_parameter to both DeviceTree (making use the new maximum-speed DT property) and platform_data. Signed-off-by: Felipe Balbi <balbi@ti.com>
2013-07-29usb: dwc3: let non-DT platforms pass tx-fifo-resize flag;Felipe Balbi2-2/+28
in case we're not in a DT boot, we should still be able to tell the driver how to behave. In order to be able to pass flags to the driver, we introduce platform_data structure which the core driver should use. Signed-off-by: Felipe Balbi <balbi@ti.com>
2013-07-29usb: common: introduce of_usb_get_maximum_speed()Felipe Balbi3-11/+70
this helper will be used for controllers which want to work at a lower speed even though they support higher USB transfer rates. One such case is Texas Instruments' AM437x SoC where it uses a USB3 controller without a USB3 PHY, rendering the controller USB2-only. Signed-off-by: Felipe Balbi <balbi@ti.com>
2013-07-29usb: phy: protect against NULL phy pointersFelipe Balbi1-9/+9

2013-07-29usb: dwc3: switch to GPL v2 onlyFelipe Balbi12-304/+91
This is a Linux-only driver which makes use of GPL-only symbols. It makes no sense to maintain Dual BSD/GPL licensing for this driver. Considering that the amount of work to use this driver in any different operating system would likely be as large as developing the driver from scratch and considering that we depend on GPL-only symbols, we will switch over to a GPL v2-only license.

2013-07-29usb: gadget: remove imx_udcFelipe Balbi4-1911/+0
That driver hasn't been really maintained for a long time. It doesn't compile in any way, it includes non-existent headers, has no users, and is just plain broken. The person who used to work with that driver has publicly stated that he has no plans to touch that driver again and is ok with removal[1]. Due to these factors, imx_udc is now removed from the tree, if someone really believe it needs to be kept, please fix the bugs in that driver.

2013-07-29usb: dwc3: make glue layers selectableFelipe Balbi2-10/+35
Glue layers are starting to have separate requirements. For example, OMAP's glue layer is starting to use extcon framework which no one else needs. In order to make it clear the proper dependencies, we are now allowing glue layers to be selectable so that each glue layer can list their own dependencies without messing with the core IP driver.

2013-07-29usb: musb: unmap reqs in musb_gadget_queue()'s error caseSebastian Andrzej Siewior1-2/+3
If the descriptor is missing the reqeust is never unmapped. This patch changes this and renames the cleanup label to unlock since there is no cleanup done. The cleanup would revert the allocation of ressource (i.e. this dma mapping) but it does not, it simply unlocks and returns.

2013-07-29usb: musb: core: call dma_controller_destroy() in the err pathSebastian Andrzej Siewior1-0/+2

2013-07-29usb: musb: remove a few is_dma_capable() in init/exit codeSebastian Andrzej Siewior1-4/+3
This patch removes is_dma_capable() and an ifdef in the init/exit path around init/de-init of the dma_controller. Since we have the empty stubs in the PIO code we can call it without gcc trouble. Earlier we had an ifdef and the is_dma_capable() macro where gcc ignored the if (0) path even that the function was not around :) Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Felipe Balbi <balbi@ti.com>

2013-07-29usb: musb: dma: merge ->start/stop into create/destroySebastian Andrzej Siewior6-77/+20
The core code creates a controller and immediately after that it calls the ->start() callback. This one might drop an error but nobody cares. The same thing happens in the destroy corner: First ->stop() called followed by destroy callback. So why not merge those two into the same function since there is no difference.

2013-07-29usb: musb: musbhsdma: drop the controller check in dma_controller_destroy()Sebastian Andrzej Siewior1-3/+0
This check is hardly required and alas is wrong. 'c' might be NULL but the chances are low that 'controller' after the container_of() becomes NULL. Since no other DMA implementation is doing that and musb-core does not call it with a NULL pointer it can dropped.

The first patch is a real fix to render the console correctly as the driver used to just drop irq renderering as too hard, this also fixes a sleeping while atomic warning. The other two patches are the big ugly ones that redo how the driver allocates objects and reserves them and makes things all work properly, I've tested this in a VM, and compared to the current code which hits a lockdep warning and the sleep while atomic warning before failing.

2013-07-26Revert "ACPI / video / i915: No ACPI backlight if firmware expects Windows 8"Rafael J. Wysocki6-87/+11
We attempted to address a regression introduced by commit a57f7f9 (ACPICA: Add Windows8/Server2012 string for _OSI method.) after which ACPI video backlight support doesn't work on a number of systems, because the relevant AML methods in the ACPI tables in their BIOSes become useless after the BIOS has been told that the OS is compatible with Windows 8. That problem is tracked by the bug entry at: https://bugzilla.kernel.org/show_bug.cgi?id=51231 Commit 8c5bd7a (ACPI / video / i915: No ACPI backlight if firmware expects Windows 8) introduced for this purpose essentially prevented the ACPI backlight support from being used if the BIOS had been told that the OS was compatible with Windows 8 and the i915 driver was loaded, in which case the backlight would always be handled by i915. Unfortunately, however, that turned out to cause problems with backlight to appear on multiple systems with symptoms indicating that i915 was unable to control the backlight on those systems as expected. For this reason, revert commit 8c5bd7a, but leave the function acpi_video_backlight_quirks() introduced by it, because another commit on top of it uses that function.

2013-07-26tracing: Remove locking trace_types_lock from tracing_reset_all_online_cpus()Steven Rostedt (Red Hat)1-2/+1
Commit a82274151af "tracing: Protect ftrace_trace_arrays list in trace_events.c" added taking the trace_types_lock mutex in trace_events.c as there were several locations that needed it for protection. Unfortunately, it also encapsulated a call to tracing_reset_all_online_cpus() which also takes the trace_types_lock, causing a deadlock. This happens when a module has tracepoints and has been traced. When the module is removed, the trace events module notifier will grab the trace_types_lock, do a bunch of clean ups, and also clears the buffer by calling tracing_reset_all_online_cpus. This doesn't happen often which explains why it wasn't caught right away. Commit a82274151af was marked for stable, which means this must be sent to stable too.

2013-07-25mfd: max8925: fix dt code for backlightOlof Johansson1-20/+21
The device-tree enablement for max8925 has several problems, but besides the bindings being wrong (and not having seen review) there's also some bad coding practices on how to fill in the platform_data from device tree. I came across this since it causes a warning when compiling mmp2_defconfig, and instead of doing the minimal fix to silence the warning, I restructured the code a bit. This silences the warning: drivers/video/backlight/max8925_bl.c: In function 'max8925_backlight_probe': drivers/video/backlight/max8925_bl.c:177:3: warning: statement with no effect [-Wunused-value] Note that the bindings themselves need to be revisited too, but that will affect more than just the backlight driver and is best done separately; this just fixes the bad code for the backlight driver.
