The new field 'dma_range_map' in struct device is used to facilitate the
use of single or multiple offsets between mapping regions of cpu addrs and
dma addrs. It subsumes the role of "dev->dma_pfn_offset" which was only
capable of holding a single uniform offset and had no region bounds
checking.
Patchset Summary:
Enhance a PCIe host controller driver. Because of its unusual design
we are foced to change dev->dma_pfn_offset into a more general role
allowing multiple offsets. See the 'v1' notes below for more info.

As the supported LDOs on this driver are all using a selector,
change the implementation to use get_voltage_sel and
set_voltage_sel ops.

Change the binding logic to ensure that the PMIC SPMI
driver will run before the regulator code and add it to the
building system.

Hi Greg,
This patch series is part of a work I'm doing in order to be able to support
a HiKey 970 board that I recently got on my hands.
Regards,
Mauro.

submitted to drivers/{mfd,spmi,regulator}
v2:
- submitted via staging, mainly to preserve original
authorship and his SoB;
- as
Without that, the regulator's core complains with:
ldo17: ramp_delay not set
For now, use the enable time, as we don't have any datasheets from

Instead of implementing a custom set of properties, set
valid_modes_mask based on having or not a mask for enabling
the eco_mode.
This makes the code clearer, and remove some uneeded props
from DT.

Simplify the names of the DT properties and do some cleanups,

It is interesting to be able to check if the driver is doing
the right thing. So, add some debug macros to allow checking it.
