Merge tag 'pwm/for-4.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm
Pull pwm changes from Thierry Reding:
"Not much has been happening in PWM land lately, so this contains
mostly minor fixes that didn't seem urgent enough for a late
pull-request last cycle"
* tag 'pwm/for-4.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm:
pwm: Remove __init initializer for pwm_add_table()
pwm: samsung: Fix output race on disabling
pwm: mxs: Fix period divider computation
pwm: atmel-hlcdc: Add errata handling for sama5d4
pwm: pca9685: Constify struct regmap_config
pwm: imx-pwm: add explicit compatible strings and required clock properties
