regulator: Update for v4.5
Aside from a fix for a spurious warning (which caused more problems than it fixed in the fixing really) this is all driver updates, including new drivers for Dialog PV88060/90 and TI LM363x and TPS65086 devices. The qcom_smd driver has had PM8916 and PMA8084 support added. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJWlUWiAAoJECTWi3JdVIfQtywH/0joibyUbL34arXcPNCUUhlo UnhTgT1kfOoS01ODt9gU49X4/8SRL9HdjcrIV8yTz4Ldb8by8Rd3ZrkO//9zs7BF 5PIqIzEw6FT/Ovsj8Tc35irccMSrwtTIGRrA8zrM/WtWQWcIUWFxMw+j/lewIvvH jHZNTTLL5XemObSTfvzhbS6PZ8RcvRVXLNJjZYYO5xAEHNg3i5Hxao5p3QKzVJ8m P5n4jSiTY/pVePcs9dzzQTGjlzkE11KX7DBxnmXOSPZsArSaRIC53DCmqu/JoG+o 3JJBkmRx7IJb0651hclFaUl8Wl56FSst+zigeAj82b301xpVR30iG3xiwYK/AT8= =NQ6n -----END PGP SIGNATURE----- Merge tag 'regulator-v4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator Pull regulator updates from Mark Brown: "Aside from a fix for a spurious warning (which caused more problems than it fixed in the fixing really) this is all driver updates, including new drivers for Dialog PV88060/90 and TI LM363x and TPS65086 devices.

Qualcomm Resource Power Manager (RPM) over SMD
|
||||||
|
|
||||||
|
This driver is used to interface with the Resource Power Manager (RPM) found in
|
||||||
|
various Qualcomm platforms. The RPM allows each component in the system to vote
|
||||||
|
for state of the system resources, such as clocks, regulators and bus
|
||||||
|
frequencies.
|
||||||
|
|
||||||
|
The SMD information for the RPM edge should be filled out. See qcom,smd.txt for
|
||||||
|
the required edge properties. All SMD related properties will reside within the
|
||||||
|
RPM node itself.
|
||||||
|
|
||||||
|
= SUBDEVICES
|
||||||
|
|
||||||
|
The RPM exposes resources to its subnodes. The rpm_requests node must be
|
||||||
|
present and this subnode may contain children that designate regulator
|
||||||
|
resources.
