65829ef5a0 These changes deal with the issues of relative includes
introduced by the earlier clean-up and clean up few more
 things for enabling multiplatform support.
 
 The multiplatform kernel has been booted on omaps on
 top of this branch with the work-in-progress patches
 applied manually.
 
 We cannot yet enable the multiplatform support though.
 We still need the common clock framework patches, some
 solution for dma-omap.h, and serial-omap.h moved before
 we can enable it.

These changes deal with the issues of relative includes

We cannot yet enable the multiplatform support though.
We still need the common clock framework patches, some

6ba54ab4a4 ARM: OMAP: Remove omap_init_consistent_dma_size()
The only thing omap_init_consistent_dma_size() does is increase the
consistent DMA size if CONFIG_FB_OMAP_CONSISTENT_DMA_SIZE is defined.
Increasing the consistent DMA size should no longer be needed with CMA
in place.

This patch removes omap_init_consistent_dma_size() and also
arch/arm/mach-omap2/io.c:omap_common_init_early() which becomes an empty
function.

1c7ebf17a4 These changes remove plat/serial.h usage for omap2+.
Note that this branch is based on a tty commit 3e9a6321
 (tty/serial/8250: Make omap hardware workarounds local to 8250.h)
 merged with omap-for-v3.8/cleanup-headers-signed.
 
 The tty commit is needed to keep things compiling for omaps,
 and omap-for-v3.8/cleanup-headers-signed is needed to avoid
 multiple merge conflicts with the includes. I've verified
 with Greg KH that the tty commit above is immutable and OK
 to use as a base.

Also remove mach/irqs.h from gpio-omap.h and

be local to debug-leds.c.

Note that eventually when the omap1 specific drivers

This code will be eventually in drivers, and for the
code in the drivers we don't want to have any cpu_is_omap
usage. Those macros should be private to arch/arm/mach-omap1

To fix this, let's move the define for dma_omap2plus()
to dma-omap.h, and use the existing dma_attr passed in
the platform_data as the revision registers are what they
are.

Note that we can now also remove the relative includes
introduced by the recent clean-up patches.

This code should be private to mach-omap2.

The only use for it in for omap1 has been in dmtimer.c
to check for context loss. However, omap1 does not
lose context during idle, so the code is not needed.
Further, omap1 timer has OMAP_TIMER_ALWON set, so omap1
was not hitting omap_pm_get_dev_context_loss_count()
test.

bb77209432 ARM: OMAP: Move omap2+ specific parts of sram.c to mach-omap2
Let's make the omap2+ specific parts private to mach-omap2.

This leaves just a minimal shared code into plat-omap like
it should be.

bf027ca137 ARM: OMAP: Split sram.h to local headers and minimal shared header
Most of the defines are specific to omap1 and omap2+,
and should be in the local headers. Only minimal function
prototypes need to be shared.

As discussed on linux-arm-kernel, we want to avoid
relative includes for the arch/arm/*omap* shared code:

http://www.spinics.net/lists/linux-omap/msg80520.html

So this patch re-adds a minimal plat/sram.h.

The new plat/sram.h must not be included from drivers,
that will break build for omap2+ CONFIG_MULTIPLATFORM.

Note that this patch temporarily adds two more
relative includes; Those will be removed in the
following patch.

Merge tag 'omap-for-v3.8/cleanup-headers-signed' into omap-for-v3.8/cleanup-headers-serial-take2

This is the first set of omap cleanup patches for v3.8 merge
window to remove most of the remaining plat includes to get us
closer to ARM common zImage support.

To avoid a huge amount of trivial merge conflicts with includes,
this branch is based on several small topic branches coordinated
with the driver subsystem maintainers. These branches are based on
v3.7-rc1 and can also be merged into the related driver subsystem
branches as needed:

omap-for-v3.8/cleanup-headers-prepare   few trivial driver changes
omap-for-v3.8/cleanup-headers-dma       move of the DMA header
omap-for-v3.8/cleanup-headers-gpmc      GPMC and MTD changes
omap-for-v3.8/cleanup-headers-mmc       MMC related changes
omap-for-v3.8/cleanup-headers-dss       DSS related changes
omap-for-v3.8/cleanup-headers-asoc      ASoC related changes

Note that for the dma-omap.h, it was decided that it should be
is completed. For the related discussion, please see:

https://patchwork.kernel.org/patch/1519591/#

After these patches we still have a few plat headers remaining
that will be handled in later pull requests.

b15d5380e4 serial/8250/8250_early: Prevent rounding error in uartclk
Modify divisor to select the nearest baud rate divider rather than the
lowest. It minimizes baud rate errors especially on low UART clock
frequencies.

For example, if uartclk is 33000000 and baud is 115200 the ratio is
about 17.9 The current code selects 17 (5% error) but should select 18
(0.5% error).

This 5% error in baud rate leads to garbage on receiving end, while 0.5%
doesn't.

The issue showed up when using the stock 8250 driver for
Synopsys DW UART. This was on a FPGA with ~12MHz UART clock.
When we enabled early serial, we saw garbage which was narrowed down
to the rounding error.

So the bug had been latent and it only showed up with such low clock rates.

b8b345bae8 TTY: Report warning when low_latency flag is wrongly used
When a driver has the low_latency flag set and uses the schedule_flip()
function to initiate copying data to the line discipline, a workqueue is
scheduled in but never actually flushed. This is incorrect use of the
low_latency flag (driver should not support the low_latency flag, or use
the tty_flip_buffer_push() function instead). Make sure a warning is
reported to catch incorrect use of the low_latency flag.

This patch goes with: cee4ad1ed9

6b898c07cb console: use might_sleep in console_lock
Instead of BUG_ON(in_interrupt()), since that doesn't check for all
the newfangled stuff like preempt.

Note that this is valid since the console_sem is essentially used like
a real mutex with only two twists:
- we allow trylock from hardirq context
- across suspend/resume we lock the logical console_lock, but drop the
  semaphore protecting the locking state.

Now that doesn't guarantee that no one is playing tricks in
single-thread atomic contexts at suspend/resume/boot time, but
- I couldn't find anything suspicious with some grepping,
- might_sleep shouldn't die,
- and I think the upside of catching more potential issues is worth
  the risk of getting a might_sleep backtrace that would have been
  save (and then dealing with that fallout).

ecbbfd44a0 TTY: move tty buffers to tty_port
So this is it. The big step why we did all the work over the past
kernel releases. Now everything is prepared, so nothing protects us
from doing that big step.

The buffers are now in the tty_port structure and we can start
teaching the buffer helpers (insert char/string, flip etc.) to use
tty_port instead of tty_struct all around.

967fab6916 TTY: add port -> tty link
For that purpose we have to temporarily introduce a second tty back
pointer into tty_port. It is because serial layer, and maybe others,
still do not use tty_port_tty_set/get. So that we cannot set the
tty_port->tty to NULL at will now.

Yes, the fix would be to convert whole serial layer and all its users
to tty_port_tty_set/get. However we are in the process of removing the
need of tty in most of the call sites, so this would lead to a
duplicated work.

Instead we have now tty_port->itty (internal tty) which will be used
only in flush_to_ldisc. For that one it is ensured that itty is valid
wherever the work is run. IOW, the work is synchronously cancelled
before we set itty to NULL and also before hangup is processed.

After we need only tty_port and not tty_struct in most code, this
shall be changed to tty_port_tty_set/get and itty removed completely.

5cff39c69b TTY: tty_buffer, cache pointer to tty->buf
During the move of tty buffers from tty_struct to tty_port, we will
need to switch all users of buf to tty->port->buf. There are many
functions where this is accessed directly in their code many times.
Cache the tty->buf pointer in such functions now and change only
single lines in each function in the next patch.

Not that it is convenient for the next patch, but the code is now also
more readable.
