The series adds support for reading the DMA bus attributes from the
INTERFACE_DESCRIPTION (0x10) register.
The first 5 changes are a bit of rework prior to adding the actual
change in patch 6, as things need to be shifted around a bit, to enable
the clock to be enabled earlier, to be able to read
We want to enable the clock right after it is obtained. Then later we'll
want to read the core version via register-access (which requires the clock
to be enabled).
The initialization of the active_descs list can be postponed after reading
from registers (or reading the device-tree).
Signed-off-b
The 'version' of the IP core will be needed to adapt the driver to a new
feature (i.e. reading some DMA parameters from registers).
To do that, the version will be checked, so this is being moved out of the
axi_dmac_detect_caps() function.

Since these are equivalent:
(idx / objs_per_page) * PAGE_SIZE + (idx % objs_per_page) * obj_size;
idx * obj_size + (idx / objs_per_page) * (PAGE_SIZE % obj_size);
Use the latter since it is slightly faster.
It also deosn't need an extra check for obj_size being a power of 2.

Saving the 'number of bits to shift' to get the array index rather
than the 'level' saves the shift = level * 9 + 3 calculations.
In addition a shift of zero only happens for an NULL pointer,
so the 'indirect into a single page' check can be optimised for.

Nominate Nathan and myself to be point of contact for clang/LLVM related
support, after a poll at the LLVM BoF at Linux Plumbers Conf 2020.
While corporate sponsorship is beneficial, its important to not entrust
the keys to the nukes with any one entity. Should Nathan and I find

driver_deferred_probe_check_state() may return -ETIMEDOUT instead of
-EPROBE_DEFER after all built-in drivers have been probed. This can
cause issues for built-in drivers that depend on resources provided by
loadable modules.
One such case happens on Tegra where I2C controll

In ath11k_qmi_prepare_bdf_download(), ath11k_core_firmware_request() is
called, but the returned pointer is not checked for errors. Rather the
variable ret (which will always be zero) is checked by mistake. Fix
this and replace the various gotos with simple returns for clarity.
While we are at it,
laurent,
Please review or give some feedback.
