[v5,000/111] pwm: Improve lifetime tracking for pwm_chips

Hello, this is v5 of this series. The relevant changes since v4 (https://lore.kernel.org/linux-pwm/cover.1701860672.git.u.kleine-koenig@pengutronix.de): - New first patch to reshuffle functions in core.c. This is a preparation for the later changes which brings functions in a better order to not need declarations. - Fix kernel docs in several drivers - Added a few ack and review tags received for v4 - non-trivially rebased to current pwm/for-next (the changes to drivers/gpu/drm/bridge/ti-sn65dsi86.c were intrusive enough to not add the ack tag by Robert Foss I got). Handling got a bit more complicated with the recent addition of pwm_apply_atomic/pwm_apply_might_sleep the locking got more complicated. I didn't work out all the necessary details. So this series won't work as is. However as there is probably some more coordination needed to get the patches in that touch files outside of drivers/pwm and I'm confident they can stay as is, I want to get the biggest part of this series in (up to patch #106) during the next merge window and get them into next soon. After that I can spend the time necessary to fix the locking maybe to get the remaining bits in during the following merge window. There are patches touching drivers/gpu/drm/bridge/ti-sn65dsi86.c (#37 and #104), drivers/staging/greybus/pwm.c (#38 and #106), drivers/gpio/gpio-mvebu.c (#103) and drivers/leds/rgb/leds-qcom-lpg.c (#105). These depend on earlier patches in this series (#3, #39 and #40) The patches touching staging/greybus and leds-qcom-lpg already have a maintainer ack, so I'd merge them via my tree. For the other two it would be nice to get an ack to merge via my tree, too. But if you want to merge via your own tree, please tell, so we can coordinate accordingly.
