This clock is actually the gate for several clocks, including the ipg clock's output. The MIPI DSI host controller embedded in the i.MX6q/sdl SoCs takes the ipg clock as the pclk - the APB clock signal . In order to gate/ungate the ipg clock, this patch adds a new shared clock gate named as "mipi_ipg".
