This patch adds support for hardware syncpoint bases. This creates a simple mechanism to stall the command FIFO until an operation is completed.

Functions host1x_syncpt_request() and _host1x_syncpt_alloc() have been taking a separate boolean flag ('client_managed') for indicating if the syncpoint value should be tracked by the host1x driver. This patch converts the field into generic 'flags' field so that we can easily add more information while requesting a syncpoint. Clients are adapted to use the new interface accordingly.

The Tegra DRM driver currently uses some infrastructure to defer the DRM core initialization until all required devices have registered. The same infrastructure can potentially be used by any other driver that requires more than a single sub-device of the host1x module. Make the infrastructure more generic and keep only the DRM specific code in the DRM part of the driver. Eventually this will make it easy to move the DRM driver part back to the DRM subsystem.

Rework the address table code for the host1x firewall. The previous implementation allocated a bitfield but didn't check for a valid pointer so it could potentially crash. Instead, embed a static bitmap within the gr2d structure to avoid the allocation and use the Linux bitmap API to reduce code complexity. Don't annotate the driver's .remove() function __exit. Even if built in the driver can be unloaded via sysfs, so .remove() needs to stick around after initialization. Also remove the explicit initialization of the driver's .owner field to THIS_MODULE because that's now handled by the driver core. Furthermore make an error message more consistent with other subdrivers, index the syncpts array for better readability, remove a gratuituous newline and reorder some variable declarations to make the code easier to read.

For drivers which might want to disable fbdev legacy support. Select the new option in all drivers for now, so this shouldn't result in any change. Drivers need some work anyway to make fbdev support optional (if they have it implemented, that is), so the recommended way to expose this is by adding per-driver options. At least as long as most drivers don't support disabling the fbdev support. v2: Update for new drm drivers msm and rcar-du. Note that Rob's msm driver can already take advantage of this, which allows us to build msm without any fbdev depencies in the kernel! v3: Move the MODULE_* stuff from the fbdev helper file to drm_crtc_helper.c.

Parsing the device tree may cause probing to be deferred.

Tegra is a 32 bit arch. On 32 bit systems then size_t is 32 bits so "total" will never be higher than UINT_MAX because of integer overflows. We need cast to u64 first before doing the math. Also the addition earlier: unsigned int num_unpins = num_cmdbufs + num_relocs; That can overflow as well, but I think it's still safe because we check both "num_cmdbufs" and "num_relocs" again in this test.

I2C of helpers used to live in of_i2c.c but experience (from SPI) shows that it is much cleaner to have this in the core. This also removes a circular dependency between the helpers and the core, and so we can finally register child nodes in the core instead of doing this manually in each driver. So, fix the drivers and documentation, too. Signed-off-by: NWolfram Sang <wsa@the-dreams.de>

So I've stumbled over drm_fasync and wondered what it does. Digging that up is quite a story. First I've had to read up on what this does and ended up being rather bewildered why peopled loved signals so much back in the days that they've created SIGIO just for that ... Then I wondered how this ever works, and what that strange "No-op." comment right above it should mean. After all calling the core fasync helper is pretty obviously not a noop. After reading through the kernels FASYNC implementation I've noticed that signals are only sent out to the processes attached with FASYNC by calling kill_fasync. No merged drm driver has ever done that. After more digging I've found out that the only driver that ever used this is the so called GAMMA driver. I've frankly never heard of such a gpu brand ever before. Now FASYNC seems to not have been the only bad thing with that driver, since Dave Airlie removed it from the drm driver with prejudice: commit 1430163b4bbf7b00367ea1066c1c5fe85dbeefed Author: Dave Airlie <airlied@linux.ie> Date: Sun Aug 29 12:04:35 2004 +0000 Drop GAMMA DRM from a great height ... Long story short, the drm fasync support seems to be doing absolutely nothing. And the only user of it was never merged into the upstream kernel. And we don't need any fops->fasync callback since the fcntl implementation in the kernel already implements the noop case correctly. So stop this particular cargo-cult and rip it all out. v2: Kill drm_fasync assignments in rcar (newly added) and imx drivers (somehow I've missed that one in staging). Also drop the reference in the drm DocBook. ARM compile-fail reported by Rob Clark. v3: Move the removal of dev->buf_asnyc assignment in drm_setup to this patch here. v4: Actually git add ... tsk.
