in order to make our IRQ handler thread easier to read, we re-factor the inner loop to a separate function. Signed-off-by: NFelipe Balbi <balbi@ti.com>

that function isn't really processing any event buffer, rather just checking whether it contains events to be processed. Due to that reason, we're reaning it to dwc3_check_event_buf() instead. Signed-off-by: NFelipe Balbi <balbi@ti.com>

We can make use of bit 31 of the GEVNTSIZ(n) registers to mask/unmask interrupts from that particular interrupter. With that feature, we can easily drop IRQF_ONESHOT from our driver which makes it possible to properly change IRQ priorities when using RT patchset *and* it allows us to make use of the scheduler to choose the proper time to handle this IRQ thread.

That register has more than just the event buffer size; we can also mask and unmask that particular interrupter on bit 31 of that register. In this patch we introduce the necessary macros and make sure to use the new macros while also making sure we mask interrupts during driver removal. Signed-off-by: NFelipe Balbi <balbi@ti.com>

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.

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.

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: NFelipe Balbi <balbi@ti.com>

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: NFelipe Balbi <balbi@ti.com>

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: NFelipe Balbi <balbi@ti.com>

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.

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.

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.

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.

The cleanup in the error is missing the dma controller. The structure is allocated at runtime and ux500 allocates even a little more than just this struct. So cleanup! Signed-off-by: NSebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: NFelipe Balbi <balbi@ti.com>
-
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: NSebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: NFelipe Balbi <balbi@ti.com>

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.

-
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.

Pull qxl drm fixes from Dave Airlie: "Okay as I warned, the qxl driver was running a bit free and loose with its ttm object reservations and the new lockdep enabled reservation tracking shone a bright light into it, it also with the new reservations mutexes hits a possible deadlock during boot. 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. So sorry this is coming in late, I should have tested qxl before merging the mutex code, but I'd rather just fix qxl with this than revert the reservations code at this point" * 'qxl-fixes' of git://people.freedesktop.org/~airlied/linux: qxl: convert qxl driver to proper use for reservations qxl: allow creation of pre-pinned objects and use for releases. drm/qxl: add delayed fb operations
