Primecell peripherals have a standard id register that can be used to +identify the peripheral type, vendor, and revision. This value can be used for +driver matching. + +Required properties: + +- compatible : should be a specific name for the peripheral and + "arm,primecell". The specific name will match the ARM + engineering name for the logic block in the form: "arm,pl???" + +Optional properties: + +- arm,primecell-periphid : Value to override the h/w value with +- clocks : From common clock binding. First clock is phandle to clock for apb + pclk. Additional clocks are optional and specific to those peripherals. +- clock-names : From common clock binding.
