I've bisected and confirmed that it was indeed this patch that regresses
for one of my SX1301 concentrators.

I noticed that this patch changed the behavior from writing the enable
bit only on one radio to also writing zero to the other. Default value
for the bit was enabled, so a functional change in theory. I therefore
tried enabling radio A clock output on the hanging one. However ...

I've posted a fix for our regmap_bus that lead to the sx125x writes not
taking effect. I.e., no clk_out was ever disabled. Otherwise only the
XOSC register writes were reordered compared to clock output enable, so
I spot no change to SX125x or SX130x registers that could cause this.

I've amended error handling and debug output (cf. below) and verified:

We never return from the sx125x_clkout_enable() performing the
regmap_field_write() on our regmap_bus, which in turn uses a SPI regmap
in sx1301_regmap_bus_read().

A notable difference between my two concentrators is that the working
one is using spi-gpio driver, the regressing one spi-sun6i.

Two things stood out in spi-sun6i: It uses a completion (I do not run
into its timeout warning!), and it uses clk_{get,set}_rate().

Given that observed symptoms were CPU stalls, workqueue hangs and RCU
problems, requiring a power-cycle to recover, I wonder whether we are
running into some atomic/locking issue with clk_enable()? Is it valid at
all to use SPI/regmap for clk_enable()? If it is, is there a known issue
specific to spi-sun6i (A64) in 4.20.0?
I already tried setting .disable_locking = true in both regmap_configs.
Any suggestions how to further debug?

Thanks,
Andreas

There it does not return from its first SPI-backed regmap_write().
