Re: [PATCH v6 0/4] Fix bugs in kona pwm driver and pwm core

[Jonathan Richardson]

Pinging maintainer and others. Could you please let me know when you can
provide feedback on this patchset.

Tim, were you ok with these changes now or do you still have concerns
about changing the driver? I didn't hear back from after our last
conversation. If there are still concerns we could possibly make a new
cygnus pwm driver, though it would be mostly the same as the existing
kona driver. Or add a DT version to the existing driver that has the new
modified behaviour - though I think this would be messy.

Thanks.
