media: venus: don't abuse dma_alloc for non-DMA allocations
In venus_boot(), we pass a pointer to a phys_addr_t
into dmam_alloc_coherent, which the compiler warns about:
platform/qcom/venus/firmware.c: In function 'venus_boot':
platform/qcom/venus/firmware.c:63:49: error: passing argument 3 of 'dmam_alloc_coherent' from incompatible pointer type [-Werror=incompatible-pointer-types]
To avoid the error refactor venus_boot function by discard
dma_alloc_coherent invocation because we don't want to map the
memory for the device. Something more, the usage of
DMA mapping API is actually wrong and the current
implementation relies on several bugs in DMA mapping code.
When these bugs are fixed that will break firmware loading,
so fix this now to avoid future troubles.
The meaning of venus_boot is to copy the content of the
firmware buffer into reserved (and memblock removed)
block of memory and pass that physical address to the
trusted zone for authentication and mapping through iommu
form the secure world. After iommu mapping is done the iova
is passed as ane entry point to the remote processor.
After this change memory-region property is parsed manually
and the physical address is memremap to CPU, call mdt_load to
load firmware segments into proper places and unmap
reserved memory.

The problem is that in the error case, we've incremented the data ptr
but not decremented rem_bytes, and keep reading (presumably garbage)
until eventually we go beyond the end of the buffer.
Instead, on first error, we should probably just bail out. Other
option is to increment read_bytes by sizeof(u32) before the switch,
rather than only accounting for the ptype header in the non-error
case. Note that in this case it is HFI_ERR_SYS_INVALID_PARAMETER,
ie. an unrecognized/unsupported parameter, so interpreting the next
word as a property type would be bogus. The other error cases are
due to truncated buffer, so there isn't likely to be anything valid
to interpret in the remainder of the buffer. So just bailing seems
like a reasonable solution.

media: dvb-frontends/stv0367: improve QAM fe_status
While cab_state->state gives a quite accurate indication of the demod
signal status, it might be incorrect if cab_algo() wasn't able to
determine the exact status, with cab_algo() being the only place where
this status was updated from, and it is only called upon tuning to new
parameters passed to set_frontend(). Thus, the status will be wrong
until the demod is retuned. With the cab_signal_type parsing in
read_status(), this results in unusual fe_states like FE_HAS_SIGNAL |
FE_HAS_CARRIER | FE_HAS_LOCK, which, while userspace applications check
for FE_HAS_LOCK and work fine, leads to missing CNR or UCB stats.
Fix this by re-reading CAB_FSM_STATUS and updating cab_state->state() in
read_status(). While at it, refactor the fsm/qamfeclock and the
fsm->signaltype parsing into separate functions to make things cleaner
and deduplicate code. Also, assume full QAM FEC lock equals full
FE_STATUS.

media: dvb-frontends/cxd2841er: do sleep on delivery system change
Discovered using w_scan when scanning DVB-T/T2: When w_scan goes from -T
to -T2, it does so without stopping the frontend using .sleep. Due to
this, the demod operation mode isn't re-setup, but as it still is in
STATE_ACTIVE_TC, PLP and T2 Profile are set up, but only retune_active()
is called, leaving the demod in T mode, thus not operable on any T2
frequency.
Fix this by putting the demod to sleep if priv->system isn't equal to
p->delsys. To properly accomplish this, sleep_tc() is split into
sleep_tc() and shutdown_tc(), where sleep_tc() will only perform the
sleep operation, while shutdown_tc() additionally performs the full
demod shutdown (to keep the behaviour when the .sleep FE_OP is called).

This fixes ie. dvb-fe-tool getting confused and assuming a DVBv3 FE on idle
frontends when the FE has been put to sleep using sleep().
Also, in read_status(), don't immediately return when no demod is active,
so the remaining code has a chance to clear the signal statistics.
