Now, we start converting tty buffer functions to actually use
tty_port. This will allow us to get rid of the need of tty pointer in
many call sites. Only tty_port will be needed and hence no more
tty_port_tty_get calls in those paths.
Now 4 string flipping ones are on turn:
* tty_insert_flip_string_flags
* tty_insert_flip_string_fixed_flag
* tty_prepare_flip_string
* tty_prepare_flip_string_flags

* DT binding for arc-uart
* With alll the bits in place we can now use DT probing.
Note that there's a bit of kludge right now because earlyprintk portion
of driver can't use the DT infrastrcuture to get resoures/plat_data.
This requires some infrastructre changes to of_flat_ framework

This is in preparation for devicetree based probing, where earlyprintk
won't have access to DT serial aliases which the normal probe would
absolutely rely on.

probe routine could index into port[] with -ve index. The check in
arc_uart_init_one() was too late.
This came to light when trying to port driver to CONFIG_OF, where
bydefault of-core code sets -ve platform dev id and in absence of
DT serial aliases, driver would use the -ve index.

NVIDIA's Tegra has multiple UART controller which supports:
- APB DMA based controller fifo read/write.
- End Of Data interrupt in incoming data to know whether end
of frame achieve or not.
- HW controlled RTS and CTS flow control to reduce SW overhead.
Add serial driver to use all above feature.

CSR SiRFmarco's UART IP is same with SiRFprimaII except that
it has two more uart ports.
this patch makes the old driver support new SiRFmarco as well:
1. add .compatible = "sirf,marco-uart" to OF match table
2. add two ports in the port table
3. take spin_lock in isr to avoid the conflict of threads opening
uart on CPU1 and isr running on CPU0.
For 3, we did see some problems on SiRFmarco as SiRFmarco is a
SMP SoC but the old SiRFprimaII is UP.

Some systems require the additional communication functionality of a
9-bit UART. For that we could use the "stick" (mark/space) parity
bit supported on omap serial device. When is set, if PARODD is set the
parity bit is always 1; if PARODD is not set, then the parity bit is
always 0.

After f65aad41772f("MIPS: Cavium: Add EDAC support."), when entering
the "Device Drivers" toplevel menu in menuconfig, the suboptions behind
EDAC appeared merged with the rest of the device drivers types. This was
because the menuconfig option EDAC is querying an EDAC_SUPPORT Kconfig
bool which was defined after the menu definition.
When pushing EDAC_SUPPORT up, before the menu definition, the variable
is defined earlier and the above menuconfig artifact doesn't happen.
Drop a useless menuconfig comment while at it.

This patch fixes use-after-free and double-free bugs in
edac_mc_sysfs_exit(). mci_pdev has single reference and put_device()
calls mc_attr_release() which calls kfree(). The following
device_del() works with already released memory. An another kfree() in
edac_mc_sysfs_exit() releses the same memory again. Great.

"People are back from the holiday breaks, and it shows. Here are a
bunch of fixes for a number of platforms:
- A couple of small fixes for Nomadik
- A larger set of changes for kirkwood/mvebu
- uart driver selection, dt clocks, gpio-poweroff fixups, a few
__init annotation fixes and some error handling improvement in
their xor dma driver.
- i.MX had a couple of minor fixes (and a critical one for flexcan2
clock setup)
- MXS has a small board fix and a framebuffer bugfix
- A set of fixes for Samsung Exynos, fixing default bootargs and some
Exynos5440 clock issues
- A set of OMAP changes including PM fixes and a few sparse warning
fixups
All in all a bit more positive code delta than we'd ideally want to
see here, mostly from the OMAP PM changes, but nothing overly crazy."

The VDCTRL4 register does not provide the MXS SET/CLR/TOGGLE feature.
The write in mxsfb_disable_controller() sets the data_cnt for the LCD
DMA to 0 which obviously means the max. count for the LCD DMA and
leads to overwriting arbitrary memory when the display is unblanked.

When a channel fails to initialize, we release all ressources,
including clocks. However, a XOR unit is not necessarily associated to
a clock (some variants of Marvell SoCs have a clock for XOR units,
some don't), so we shouldn't unconditionally be releasing the clock.
Instead, just like we do in the mv_xor_remove() function, we should
check if one clock was found before releasing it.

When mv_xor_channel_add() fails for one XOR channel, we jump to the
err_channel_add label to clean up all previous channels that had been
initialized correctly. Unfortunately, while handling this error
condition, we were disposing the IRQ mapping before calling
mv_xor_channel_remove() (which does the free_irq()), which is
incorrect.
Instead, do things properly in the reverse order of the
initialization: first remove the XOR channel (so that free_irq() is
done), and then dispose the IRQ mapping.
This avoids ugly warnings when for some reason one of the XOR channel
fails to initialize.

Noticed while reviewing the fence locking in the radeon pageflip
handler.
v2: Instead of grabbing the bdev->fence_lock in object_transfer just
move the single callsite of that function a few lines, so that it is
protected by the fence_lock. Suggested by Jerome Glisse.
v3: Fix typo in commit message.

vga-switcheroo with apple-gmux does not switch correctly on my system. The PCI
configuration space is not restored correctly, resulting in MSI not working after switch.
Only useful item in dmesg is:
[ 33.922807] radeon 0000:01:00.0: Refused to change power state, currently in D3
I did some testing, dumping the difference in ms between first succesful switch
from D3 to D0, and it seems that there is slightly more than 20 ms difference when
the device is re-enabled through vga-switcheroo.
So bump the re-enable d3 delay to 20 ms to handle this, which fixes msi not working
on my system after switcheroo-ing. Default d3_delay value is PCI_PM_D3_WAIT, 10 ms.

- r6xx actually uses a slightly different packet format,
although both formats seem to work ok.
- r7xx doesn't have the count multiple of 2 limitation.

Increasing ref counts of both dma-buf and gem for imported dma-buf come from gem
makes memory leak. release function of dma-buf cannot be called because f_count
of dma-buf increased by importing gem and gem ref count cannot be decrease
because of exported dma-buf.
So I add dma_buf_put() for imported gem come from its own gem into each drivers
having prime_import and prime_export capabilities. With this, only gem ref
count is increased if importing gem exported from gem of same driver.

This patch implements the exynos_drm_crtc_finish_pageflip in
exynos_drm_crtc.c. This avoids the duplication of same code
in mixer, fimd and vidi.

If fimd is runtime suspended (by DPMS OFF), fimd_suspend does not
call fimd_activate(false) and just returns. Similarily the check in
fimd_resume should not resume if previously runtime_suspended.
Instead the existing check does the opposite. So if fimd was not
runtime suspended, suspend will turn off fimd but resume will not turn
it on. This patch fixes this issue by reversing the condition.

devm_request_and_ioremap API checks for NULL. Hence explicit

devm_* APIs are device managed and get freed automatically when the
device detaches. Thus explicit freeing is not needed. This saves some
code.
