- Fix dra7 for hardware issues limiting L4Per and L3init power domains
  to on state. Without this the devices may not work correctly after
  some time of use because of asymmetric aging. And related to this,
  let's also remove the unusable states.

- Always select omap interconnect for am43x as otherwise the am43x
  only configurations will not boot properly. This can happen easily
  for any product kernels that leave out other SoCs to save memory.

- Fix DSS PLL2 addresses that have gone unused for now

- Select erratum 430973 for omap3, this is now safe to do and can
  save quite a bit of debugging time for people who may have left

ARM: dts: STi: stih407-family: Disable reserved-memory co-processor nodes

This patch fixes a non-booting issue in Mainline.

When booting with a compressed kernel, we need to be careful how we
populate memory close to DDR start.  AUTO_ZRELADDR is enabled by default
in multi-arch enabled configurations, which place some restrictions on
where the kernel is placed and where it will be uncompressed to on boot.

AUTO_ZRELADDR takes the decompressor code's start address and masks out
the bottom 28 bits to obtain an address to uncompress the kernel to
(thus a load address of 0x42000000 means that the kernel will be
uncompressed to 0x40000000 i.e. DDR START on this platform).

Even changing the load address to after the co-processor's shared memory
won't render a booting platform, since the AUTO_ZRELADDR algorithm still
ensures the kernel is uncompressed into memory shared with the first
co-processor (0x40000000).

Another option would be to move loading to 0x4A000000, since this will
mean the decompressor will decompress the kernel to 0x48000000. However,
this would mean a large chunk (0x44000000 => 0x48000000 (64MB)) of
memory would essentially be wasted for no good reason.

Until we can work with ST to find a suitable memory location to
relocate co-processor shared memory, let's disable the shared memory
nodes.  This will ensure a working platform in the mean time.

NB: The more observant of you will notice that we're leaving the DMU
shared memory node enabled; this is because a) it is the only one in
active use at the time of this writing and b) it is not affected by
the current default behaviour which is causing issues.

8 years agostaging/android: sync_debug: unproxify debugfs files' fops
Nicolai Stange [Fri, 27 May 2016 18:03:54 +0000 (20:03 +0200)]
staging/android: sync_debug: unproxify debugfs files' fops

Since commit 49d200deaa68 ("debugfs: prevent access to removed files'
private data"), a debugfs file's file_operations methods get proxied
through lifetime aware wrappers.

However, only a certain subset of the file_operations members is supported
by debugfs and ->compat_ioctl isn't among them -- it appears to be NULL
from the VFS layer's perspective.

This behaviour breaks the /sys/kernel/debug/sync/sw_sync file introduced
concurrently with commit a44eb74cd413 ("staging/android: move SW_SYNC_USER
to a debugfs file").

Since that file never gets removed, there is no file removal race and thus,
a lifetime checking proxy isn't needed.

Avoid the proxying for /sys/kernel/debug/sync/sw_sync by creating it via
debugfs_create_file_unsafe() rather than debugfs_create_file().
For consistency, do the same for /sys/kernel/debug/sync/info.

Fixes: 49d200deaa68 ("debugfs: prevent access to removed files' private data")
Fixes: a44eb74cd413 ("staging/android: move SW_SYNC_USER to a debugfs file")

fence_ops, and in the last few commits we removed all it ops in favor

8 years agostaging/android: remove .{fence, timeline}_value_str() from timeline_ops

Now that the value of fence and the timeline are not stored by sw_sync
anymore we can remove this extra abstraction to retrieve this data.

This patch changes both fence_ops (.fence_value_str and
.timeline_value_str) to return the str directly.

It also clean up struct sync_timeline_ops by removing both ops from there.

Arnd Bergmann [Fri, 17 Jun 2016 19:56:15 +0000 (21:56 +0200)]
staging: comedi: avoid using timeval

Comedi uses 32-bit seconds for its timestamps, on both 32-bit and
64-bit machines. For all I can tell, this was originally meant as
a 'timespec', which would overflow in 2038 because of the use of
a signed 'long' on 32-bit machines, but it is now used as an
array of two unsigned 'lsampl_t' values in comedilib, which will
only overflow in 2106, on both 32-bit and 64-bit machines.

In an effort to get rid of all uses of 'struct timeval' in the kernel,
this replaces the internal code with a call to ktime_get_real_ts64()
and a comment at the location of the conversion.
