clk: Add brcm,bcm6345-gate-clk device tree binding
Subsystems (3)
PATCH 1/2 clk: Add brcm,bcm6345-gate-clk device tree binding
Add device tree binding for the BCM6345's gated clocks.
The BCM6345 contains clocks gated with a register. Clocks are indexed by bits in the register and are active high. Clock gate bits are interleaved with other status bits and configurable clocks in the same register.

PATCH 2/2 clk: bcm6345: Add BCM6345 gated clock support
The BCM6345 contains clocks gated with a register. Clocks are indexed by bits in the register and are active high. Clock gate bits are interleaved with other status bits and configurable clocks in the same register.
Enabled by default for BMIPS_GENERIC.
