Subject: [PATCH v2 lora-next 0/4] migration to regmap and clk framework

This series completes the sx1301 migration to regmap by replaceing the SPI
burst read and write with regmap raw reads and writes, this solution is a work
around until there is regmap_noinc_read/write API merged as it sepends on the
fact that we have the regcache turned off.
regmap_noinc_read is available in 4.19 however a write varient isn't.

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 (4):
  net: lora: sx1301: convert burst spi functions to regmap raw
  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
