arm64: dts: add support for Ka-Ro electronics TXSD-410E module
The TXSD-410E is a SoM largely compatible to a Qualcomm APQ8016-SBC
board in a different form factor.
It features an LVDS output instead of HDMI and has no onboard USB hub.
commit 691849c2ffa1 ("Move to new qcom_smem_get() api") left over a
check of a now uninitialized variable.
Remove the variable and do the check in the hopefully intended
manner.

drm: msm: dsi: keep a reference on msm_host->device_node until driver removal
Since the device_node pointer is stored for later usage, its refcount
must not be decreased to prevent deletion of the object while it may
still be referenced.
msm8916-wcd codec is found in Qualcomm msm8916 and apq8016 processors.
This codec IP is split in to two parts(Digital & Analog), Analog part
is integrated in to PMIC PM8916 and the digital part is integrated into
Application processor. Register access to the analog part is done via
SPMI interface to PMIC, and registers on the Application processor are
memory mapped. Data transfer between Analog and Digital Die is done via
a internal bus called PDM.
This codec support includes:
- 3 Microphones: Primary Mic(Handset mic), Headset Mic and Secondary Mic.
- 2 Digital Microphones.
- 2 Mic Bias Circuits.
- Earpiece
- Headset
- Loud Speaker.
This patch introduces SOC_SINGLE_S8_TLV() macro for volume control
on chips which supports both negative and positive gains with sign
bit on a 8 bit register, Gain ranges from -128 to +127 with a
predefined step size.
Currently we only have support to DOUBLE_S8_TLV() which does not fit
for cases where we just have separate gain control register for each
channel.
One of the Qualcomm SOC msm8916 has such gain control register whose gain
range is from -38.4dB to +38.4dB with step size of 0.3dB.
This patch adds DT bindings required for msm8916 codec which is
integrated in msm8916 and apq8016 SOCs.
Codec IP is divided into two parts, first analog which is integrated
in pmic pm8916 and secondly digital part which is integrated into
application processor. Codec register controls are also split across
pmic an lpass. Analog part is controlled via spmi bus to pmic, registers
on the Application processor are memory mapped.

arm64: dts: qcom: msm8916: Use fixed factor xo clock
The rpmcc driver is providing the XO clock, which is the parent of almost
all clocks. But during boot, this driver may probe later and leave most of
the clocks without parent. The common clock framework currently reports
invalid rate for orphan clocks and this may confuse drivers.
To resolve this, use fixed clocks registration until we have some support
to deal with the this issue. Removing the generic rpmcc compatible is
enough to switch back to fixed factor XO clock.

Bluetooth: Introduce Qualcomm WCNSS SMD based HCI driver
The Qualcomm WCNSS chip provides two SMD channels to the BT core; one

Having multiple loadable modules with the same name cannot work

Also, the qrtr driver uses the SMD interface and has a Kconfig dependency,
but also allows for compile-testing when SMD is disabled. However, if
with QCOM_SMD=m and COMPILE_TEST=y we can end up with QRTR_SMD=y and
that fails with a related link error.
The changes the dependency so we can still compile-test the driver but
not have it built-in if SMD is a module, to avoid running in the broken
configuration, and changes the Makefile to provide the driver under
a different module name.
