Subject: [PATCH v3 lora-next 0/5] based on 4.19-rc7 migration to regmap and clk framewor

This series is designed to be applied to a lora-next which is based on
v4.19-rc7, not what is currently upstream, there were no additional changes
in this rebase.

In this series we add the write variant to regmap_noinc then use it within
the sx1301 driver to load firmware.

We complete the sx1301 migration to regmap by replacing the SPI burst read
and write with regmap_noinc_read and write.

The various fields of the sx1301 are converted to regmap to pass the read
modify write down to the regmap layer and reduce our code.
The downside is that in the cases of the hand optimised multiple field writes
at once within one register, however if it is desirable these can be replaced
with regmap_update_bits.

Apply the same regmap treatment for the radio device and allow it to register as
a clock provider, this clock is enabled when the lora link is brought up as it
is required prior to calibration of the concentrator.

Ben Whitten (5):
  regmap: Add regmap_noinc_write API
  net: lora: sx1301: replace burst spi functions with regmap_noinc
  net: lora: sx1301: convert to using regmap fields for bit ops
  net: lora: sx125x: convert to regmap fields
  net: lora: sx125x sx1301: allow radio to register as a clk provider
