When CONFIG_QCOM_SCM is y and CONFIG_HAVE_ARM_SMCCC
is not set, compiling errors are encountered as follows:
drivers/firmware/qcom_scm-smc.o: In function `__scm_smc_do_quirk':
qcom_scm-smc.c:(.text+0x36): undefined reference to `__arm_smccc_smc'
drivers/firmware/qcom_scm-legacy.o: In function `scm_legacy_call':
qcom_scm-legacy.c:(.text+0xe2): undefined reference to `__arm_smccc_smc'
drivers/firmware/qcom_scm-legacy.o: In function `scm_legacy_call_atomic':
qcom_scm-legacy.c:(.text+0x1f0): undefined reference to `__arm_smccc_smc'
Note that __arm_smccc_smc is defined when HAVE_ARM_SMCCC is y.
So add dependency on HAVE_ARM_SMCCC in QCOM_SCM configuration.

When async binder buffer got exhausted, some normal oneway transactions
will also be discarded and may cause system or application failures. By
that time, the binder debug information we dump may not be relevant to
the root cause. And this issue is difficult to debug if without the
backtrace of the thread sending spam.
This change will send BR_ONEWAY_SPAM_SUSPECT to userspace when oneway
spamming is detected, request to dump current backtrace. Oneway spamming
will be reported only once when exceeding the threshold (target process
dips below 80% of its oneway space, and current process is responsible for
either more than 50 transactions, or more than 50% of the oneway space).
And the detection will restart when the async buffer has returned to a
healthy state.

intel_link_probe() could return error and dev_get_drvdata() will return
null in such case. So we have to test link->cdns after
link->cdns = dev_get_drvdata(&ldev->auxdev.dev);
Otherwise, we will meet the "kernel NULL pointer dereference" error.

Internally used portconfig array for storing port bandwidth
params starts from offset zero. However port zero is not really
used and we also copy the bus parameters to offset zero.
So basically we endup with a code which has to subtract 1 from port
number to get to port parameters.
This is bit confusing to the reader so, make this bit more obvious by only
copying the parameters to offset 1 instead of zero. This will avoid doing
-1 every time when we try to get port params.
Similar thing has been recently done with din/dout_port_mask.

SoundWire device ports are statically mapped to Controller ports during
design. Add support to read these from SoundWire devices.
This controller uses static port map info to setup bandwidth
parameters for those ports.
A generic port allocation is not possible in this cases!

currently the internal bitmask used for allocating ports starts with offset 0.
This is bit confusing as data port numbers on Qualcomm controller are valid
from 1 to 14. So adjust this bit mask accordingly, this will also help while

Some of the SoundWire device ports are statically mapped to Controller
ports during design, however there is no way to expose this information
to the controller. Controllers like Qualcomm ones use this info to setup
static bandwidth parameters for those ports.
A generic port allocation is not possible in this cases!
So this patch adds a new member m_port_map to struct sdw_slave to expose
this static map.
