This is prior art:
https://patchwork.ozlabs.org/project/linux-pwm/list/?series=85452&state=%2A&archive=both
unfortunately this didn't get an Ack by Shawn and Thierry (added to
recipients) marked it as "Not Applicable".
Given that the driver change is in Linus Torvald's tree now (since
v5.1-rc1~38) it doesn't matter much via which tree this goes in and
Shawn's tree is the easier now.
@Shawn: Would you please apply my patches? If you don't have them any
more, I can bounce them to you. See
git show v5.1-rc1~38^2~17 -- drivers/pwm/Kconfig
for their justification.

IMHO this should be debugged independent of this patch.

PWM_IMX is gone, so this can be dropped (but see my patch referenced
above).

Noticed that after sending; your patch deals with this correctly and
also covers imx_v4_v5

I understood that. In this case however it would in my eyes have made
sense to take these patches together with the patch that does the driver
split via the pwm tree to make it less likely that people using the
respective defconfigs don't get the PWM driver enabled. That's the
situation now on 5.1-rc1 and people actuall hit this problem. :-| That's
why I wrote:
I think the easiest handling would be to let them go via the pwm
tree with Shawn's Ack to get the update near to the actual split
into the mainline.
in the cover letter.
