Merge tag 'samsung-drivers-4.18' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into next/drivers
Samsung soc drivers changes for v4.18 1. Clock operations during power domain on/off were moved to respective clock driver so clean up obsolete code from power domain driver. * tag 'samsung-drivers-4.18' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux: soc: samsung: pm_domains: Deprecate support for clocks Signed-off-by: Olof Johansson <olof@lixom.net>

Optional Properties:
- label: Human readable string with domain name. Will be visible in userspace
to let user to distinguish between multiple domains in SoC.
-- clocks: List of clock handles. The parent clocks of the input clocks to the
- devices in this power domain are set to oscclk before power gating
- and restored back after powering on a domain. This is required for
- all domains which are powered on and off and not required for unused
- domains.
-- clock-names: The following clocks can be specified:
- - oscclk: Oscillator clock.
- - clkN: Input clocks to the devices in this power domain. These clocks
- will be reparented to oscclk before switching power domain off.
- Their original parent will be brought back after turning on
- the domain. Maximum of 4 clocks (N = 0 to 3) are supported.
- - asbN: Clocks required by asynchronous bridges (ASB) present in
- the power domain. These clock should be enabled during power
- domain on/off operations.
- power-domains: phandle pointing to the parent power domain, for more details

Node of a device using power domains must have a power-domains property
defined with a phandle to respective power domain.
