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!
