12*833e5d42SEmmanuel Vadotdescription: >
13*833e5d42SEmmanuel Vadot  ILP clock (sometimes referred as "slow clock") on Broadcom BCM53573 devices
14*833e5d42SEmmanuel Vadot  using Cortex-A7 CPU.
15*833e5d42SEmmanuel Vadot
16*833e5d42SEmmanuel Vadot  ILP's rate has to be calculated on runtime and it depends on ALP clock which
17*833e5d42SEmmanuel Vadot  has to be referenced.
18*833e5d42SEmmanuel Vadot
19*833e5d42SEmmanuel Vadot  This clock is part of PMU (Power Management Unit), a Broadcom device handling
20*833e5d42SEmmanuel Vadot  power-related aspects. Its node must be sub-node of the PMU device.
