To allow userland to enable or disable dropping packets when descriptor
ring is exhausted, add an adapter rx_drop_en attribute.

This can be used in conjunction with flow control to mitigate packet storms
(e.g. due to network loop or DoS) by forcing the network adapter to send
pause frames whenever the ring is close to exhaustion.

Avoid ldb and ipu di clocks both using the same parent.
ldb requires pasthrough clock to avoid breaking timing while
ipu di does not.
Force ipu di clocks to use IMX6QDL_CLK_PLL2_PFD2_396M as parent
and ldb to use IMX6QDL_CLK_PLL5_VIDEO_DIV.

This fixes an issue where attempting atomic modeset while using
hdmi and display port at the same time causes ldb clock programming
to destroy the programming of hdmi that was done during the same
modeset.

Some standard resolutions like 1366x768 do not work properly with
i.MX6 SoCs, since the horizontal resolution needs to be aligned
to 8 pixels (so 1360x879 or 1368x768 would work).

This patch allocates framebuffers allocated to 8 pixels. The extra
time required to send the extra pixels are removed from the blank
time. In order to expose the correct display size to userspace,
the stride is increased without increasing the width.

Congatec's QMX6 system on module (SoM) uses a m41t62 as RTC. The
modules SQW clock output defaults to 32768 Hz. This behaviour is
used to provide the i.MX6 CKIL clock. Once the RTC driver is probed,
the clock is disabled and all i.MX6 functionality depending on
the 32 KHz clock have undefined behaviour.

The proper solution would be to describe this behaviour in DT,
but from the kernel's perspective this is a chicken-and-egg
problem (CKIL is initialized early, but properly controlling the
parent clock requires I2C).

Technically everything is fine by not touching anything, so this
works around the issue by disabling the clock handling from the
RTC driver.

This adds device tree files for the General Electric Healthcare
(GEHC) B1x5v2 series. All models make use of Congatec's QMX6 module,
which is described in its own device tree include, so that it can
also be used by other boards.

NOTE: This is not intended to be upstreamed at the moment. This
will require some cleanups and probably should not be done before
the prototype board evolved a bit further (and the TODOs have been
taken care of).

Should work:
 * Serial Console
 * µSD card
 * eMMC
 * SPI NOR flash memory
 * HDMI
 * LCD panel
 * Ethernet
 * USB
 * Alarm LEDs
 * RTC
 * Watchdog
 * Rotary encoder input
 * Touchscreen
 * Backlight
 * Power Button
 * WLAN (QMX6 resistor needs to be removed)
 * Audio

TODO / Missing:
 * Poweroff does not work
 * Charger Support
 * USB current limiting

When tsi-as-adc is configured it is possible for in7[0123]_input read to

DSA returns -EOPNOTSUPP causing systemd to set the link state to

phylink polls the fixed-link once per second to see if the GPIO has
changed state, or if the callback indicates if there has been a change
in state. It then calls the MAC to reconfigure itself to the current
state.

For some MACs, reconfiguration can result in packets being dropped.
Hence only reconfigure the MAC if the link state differs from the
netdev carrier state.

These are roaming speed enhancements. Description from the accompanying
Readme.txt:

Contains all the driver changes(stop crda, multiple auth fix) from the base.

In more detail:
- Stop updating CRDA during every roam. This shaves off 200-300ms from the
  roam time.
- Multiple authentication avoidance with the _11r -field. This is partly
  implemented here and partly in the wpa_supplicant.

The following changes from changes-from_base_driv.patch:
- Remove the compat_wireless/ string from each of the file names.
- Clean merge-conflicts from both Makefiles.
- Clean merge-conflict from struct wireless_dev in include/net/cfg80211.h.

The following local changes cleanup changes:
- Remove FT_ROAMING_ENHANCEMENTS and ENABLE_ROAMING_ENHANCEMENTS ifdefs,
  making the features always-enabled.
- Remove all changes to Makefiles.
- Remove the if(!WDEV){} -stuff altogether.
- Remove the WDEV define and replace it with the whole name of the object.
- Fix opening brace positions in ifs.
- Add space between if and the opening parentheses, as necessary.
- Move setting the _11r -field after the check the sdata->dev->ieee80211_ptr
  != NULL.

Second round of cleanup fixes:
- Remove changes to reg.c as the changes only prevent logging a debug message.
