- Increase drive-strength to 10 and add bias-pull-up as per Qualcomm suggestion
- Let vreg_l6c_2v96 voltage switch between 3.3V and 1.8
- Add reg_3v3_sdcard as card power supply
- Use GPIO_91 as card detect

This corrects a typo in the filename

This allows the driver to be found as a remote-endpoint thus a eDP
driver can defer its probe until the PTN3450 driver has been probed.

Add Fannal 7" and AOE 10.1" LVDS displays

Disable all display stuff by default. It is up to displays dtsi file to
enable what is needed.

The Qualcomm (e)DP driver does not support bridges.
Hence this is not really a bridge driver, that means there are no attach-
or enable-functions.
Instead the bridge is configured when the device is probed. After this the
hotplug-detect-gpio is pulled to high to fake to the (e)DP driver a nativ
(e)DP display has been powered on.

The MAILBOX and RPMSG drivers are required for the co-processor
communication on the QCS6490 (more specfic the QCOM_GLINK sub-system
depends on them). For whatever reasen, they have been disabled.
Re-enable them since we get compile and run time errors otherwise.

When a cpufreq-driver wants to create files in sysfs that are already
created by an oher cpufreq-driver it gets -EEXISTS.

It contains variuos additional stuff for the processor, as some
memory regions, firmware drivers, configs for memory dumps,
thermal zones, dma heaps etc.

Device can be "woken" from suspend/sleep state by pressing SW5 (SLEEP)
button on B79 carrier board

During development, we have disabled the device tree nodes for soundwire. While that is in effect, these drivers are not needed.

If the referenced files was to change, the reference we're providing would be out of date. These changes prevent this.

Ignore the ENODEV failures returned by kernel_sendmsg(). These errors
indicate that either the local port has been closed or the remote has
gone down. Neither of these scenarios are fatal and will eventually be
handled through packets that are later queued on the control port.

We do not have the USB HUB on QPS615.
QPS615 voltages are enabled via the regulators.

DP adds an i2c bus to the system. If it is not entirely/properly
configured accessing this i2c bus causes a NULL-pointer to be
dereferenced and the system to reboot.
