The irq number is only used inside the probe function, so there is no need
to keep it in the private mxs_auart_port structure.

Use a local 'irq' variable for storing the irq number instead.

Also make its type of 'int' as platform_get_irq() may fail and return a
negative number.

When the kernel command line parameter, no_console_suspend, is used,
the console should continue to output console messages during and
after system suspend. For a serial console, the serial core ensures
that the device is not shutdown when no_console_suspend is specified.
However, the default operation of the pnp bus will disable and suspend
the device and no further output occurs.

When registering the 8250 port, if the serial device is a console
set the PNP_CONSOLE capability, which prevents device power-off
if consoles are not suspending.

If the serial console is an ACPI PNP device, the PNP bus always powers
down the device at system suspend, even though the no_console_suspend
command line parameter is specified (eg., when debugging suspend/resume).

Add PNP_CONSOLE capability, which when set, prevents calling both the
->disable() and ->suspend() PNP protocol methods if console suspend
is disabled.

The change does following:
 - baud, flow, bits, parity were being overwritten as they were
   being reinitialized after parsing.  Initialize them when they are
   declared so that user provided setting are not overwritten.
 - msm_set_baud_rate() is anyway called in uart_set_options when it calls
   msm_set_termios(). msm_reset() is called when we change the baud rate.
   Hence doing away with both of these calls.
 - CR_CMD_PROTECTION_EN and CR_TX_ENABLE settings are done in msm_set_baud_rate.

On uart buffer flush, serial core resets the circular buffer.
If a DMA transfer is in progress at that time, the callback
lpuart_dma_tx_complete will move buffer's tail unconditionally,
hence tail moves beyond head. Use the flush_buffer hook to
terminate the DMA imeaditely and avoid lpuart_dma_tx_complete
being called in this situation.

To end a DMA transfer which did not consume a whole buffer (e.g. one
character only), a RX timer is used. When lots of data are received
the DMA transfer will complete and setup another DMA transfer, which
in turn might complete again. In this cases, it is not necessary to
abort the DMA transfers using the RX timer. This change pushes the
RX timer timeout into the future each time a DMA transfer completed.

Aborting the DMA was not very harmful, since the next received
character lead to setup of another RX DMA.

Move the DMA channel request to probe to avoid requesting the DMA
channel on each opening of the ttyLPx device. This also fixes a
potential issue that TX channel is not freed when only RX channel
allocation fails. The DMA channels are now handled independently,

When the UART is in DMA receive mode (RDMAS set) and one character
just arrived while another interrupt is handled (e.g. TX), the RDRF
(receiver data register full flag) is set due to the water level of
1. But since the DMA will take care of this character, there is no
need to handle it by calling lpuart_prepare_rx. Handling it leads to
adding the RX timeout timer twice:

These two copy to/from VGA memory, however on the Silicon

This is due to the hw being buggy and not handling a 64-bit transaction

We could try and create a 32-bit version of these routines,

rk3288 SoCs have a function to automatically switch between jtag/sdmmc pinmux
settings depending on the card state. This collides with a lot of assumptions.

It only works when using the internal card-detect mechanism and breaks
horribly when using either the normal card-detect via the slot-gpio function
or via any other pin. Also there is of course no link between the mmc and jtag
on the software-side, so the jtag clocks may very well be disabled when the
card is ejected and the soc switches back to the jtag pinmux.

Leaving the switching function enabled did result in mmc timeouts and rcu
stalls thus hanging the system on 3.19-rc1. Therefore disable it in all cases,
as we expect the devicetree to explicitly select either mmc or jtag pinmuxes
anyway.

We altered the device tree bindings for the Nomadik family of
pin controllers to be standard, this file was merged out-of-order
so we missed fixing this. Fix it up.

Merge tag 'omap-for-v3.19/fixes-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

Merge "omap fixes against v3.19-rc1" from Tony Lindgren:

Fixes for omaps mostly to deal with dra7 timer issues
and hypervisor mode. The other fixes are minor fixes for
various boards. The summary of the fixes is:

- Fix real-time counter rate typos for some frequencies
- Fix counter frequency drift for am572x
- Fix booting of secondary CPU in HYP mode
- Fix n900 board name for legacy user space
- Fix cpufreq in omap2plus_defconfig after Kconfig change
- Fix dra7 qspi partitions

And also, let's re-enable smc91x on some n900 boards that
we have sitting in a few test boot systems after the boot
loader dependencies got fixed.
