All legacy PWM providers have now been moved to the PWM subsystem. The plan for 3.8 is to adapt all board files to provide a lookup table for PWM devices in order to get rid of the global namespace. Subsequently, users of the legacy pwm_request() and pwm_free() functions can be migrated to the new pwm_get() and pwm_put() functions. Once this has been completed, the legacy API and the compatibility code in the core can be removed. In addition to the above, these changes also add support for configuring the polarity of a PWM signal (currently only supported on ECAP and EHRPWM) and include a much needed rework of the i.MX driver. Managed functions to obtain and release a PWM device (devm_pwm_get() and devm_pwm_put()) have been added and the pwm-backlight driver has been updated to use them. If the PWM subsystem hasn't been enabled, dummy functions are provided that allow the subsystem to safely compile out. Some common checks on input parameters have been moved to the core and removed from the drivers. Finally, a small fix corrects the description of the PWM specifier's second cell in the device tree representation. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) iQIcBAABAgAGBQJQcV6pAAoJEN0jrNd/PrOh594P/3NHPjnTiyAZpUICX4mJeoMd 1rX685HofCyX5jlHloS1pLRXYtIPZP97We5crNR/k/RujKcHAqAFzLtG2Jj93gxm nRUwLZ4xbrAgeaZeJV8YG1naWx9R1OjrK2sv+FyHRWsn9UZus2vDMV7tB0oNWo9k DMhtF1q7gQxx4nRu8z9FFybyItQinVREODNs+Gdv6AOJ36t+mOsGPL3LKZeFsIG3 LdaB1p3t/07Job4KwGYYRjkOR7bIQ+ADnnO8Pkk0a9lxkMI8rA0uFbLwgyx7Hohh xZtm8R5il2IlHwqh52RzpShceWICxCZ3htuIXTRbVa1PSEsBzZ66W2CT7sy1jPm5 lJlHgc7abaiwijtoG76I+Lgslv5UTViBuIYHSX4dH2kF3Jgm2SgTBNzZYePI5MMT BI3xc9WnwBpxgMybJsPHfU0Ff6O/9h9ab7q5lBOHkQJittahYxzWD+FgYlalcAa+ I919iFREKNZytewLnXu+4TG0RfacQoj6D5G+SquOGmXyKYRhhJ1O6WodnRZHi/0n M6J0f6fLxpomI1RMn44VYP43OPJCDYxgXYoDLwCZQL9tSWYpdhXoDrjcIPO547w1 ZS5HTXUE4DrxeYjoeqL555vtQIooM9CuH4JwKlz5zzea8NPC8eVtmNFTTWE6wKWX ZIOOLVvw/FI0/DSjBb8H =MQ5V -----END PGP SIGNATURE----- Merge tag 'for-3.7-rc1' of git://gitorious.org/linux-pwm/linux-pwm Pull pwm changes from Thierry Reding: "All legacy PWM providers have now been moved to the PWM subsystem.

Find out whether you have a PCI motherboard. PCI is the name of a
|
|
bus system, i.e. the way the CPU talks to the other stuff inside
|
|
your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
|
|
VESA. If you have PCI, say Y, otherwise N.

Unicore processors can not fetch/store information which is not
|
|
naturally aligned on the bus, i.e., a 4 byte fetch must start at an
|
|
address divisible by 4. On 32-bit Unicore processors, these non-aligned
|
|
fetch/store instructions will be emulated in software if you say
|
|
here, which has a severe performance impact. This is necessary for
|
|
correct operation of some network protocols. With an IP-only
|
|
configuration it is safe to say N, otherwise say Y.

Always use the default kernel command string, even if the boot

loader passes other arguments to the kernel.
|
|
This is useful if you cannot or don't want to change the

command-line options your boot loader passes to the kernel.
|

If unsure, say N.
