Subject: [PATCH lora-next 00/11] net: lora: sx130x: Fixes for enabling regcache

Hello,

This series fixes a number of issues that stood in the way of enabling the
regmap cache for SX130x. It goes on to enable REGCACHE_RBTREE.

1) Soft reset needs special treatment.
2) More registers need to be treated as volatile.
3) Some register field writes need to be forced.

This complements Ben Whitten's regmap conversion patches [1] I already squashed,
mainly [2]. I intend to squash these into my driver commit as well.

In my testing it has not regressed with spi-gpio or cdc-acm, nor with spi-sun6i;
given that we seem no closer to a solution for the clk lock-up, we may need to
revert that commit from [1] again.

Have a lot of fun!

Cheers,
Andreas
