7 title: Mediatek Power Domains Controller
10 - MandyJH Liu <mandyjh.liu@mediatek.com>
11 - Matthias Brugger <mbrugger@suse.com>
14 Mediatek processors include support for multiple power domains which can be
15 powered up/down by software based on different application scenes to save power.
17 IP cores belonging to a power domain should contain a 'power-domains'
22 pattern: '^power-controller(@[0-9a-f]+)?$'

102 List of names of clocks, in order to match the power-up sequencing
103 for each power domain we need to group the clocks by name. BASIC
104 clocks need to be enabled before enabling the corresponding power
105 domain, and should not have a '-' in their name (i.e mm, mfg, venc).
107 and should contain a '-' in their name (i.e mm-0, isp-0, cam-0).
