Including this driver +is an effort to be able to define proper clocks using device tree and also +cleaning all the clock and reset related code from 'arch/mips/ralink' dir. +This clock and reset driver covers all the ralink SoCs but MT7621 which is +the newest and provides gating and some differences that make it different +from its predecesors. It has its own driver since some time ago. The ralink +SoCs we are taking about are RT2880, RT3050, RT3052, RT3350, RT3352, RT3883, +RT5350, MT7620, MT7628 and MT7688.

The clock plans for this SoCs only talks about relation between +CPU frequency and BUS frequency. This relation is different depending on the +particular SoC. CPU clock is derived from XTAL frequencies. + +Depending on the SoC we have the following frequencies: +* RT2880 SoC: + - XTAL: 40 MHz. + - CPU: 250, 266, 280 or 300 MHz. + - BUS: CPU / 2 MHz. +* RT3050, RT3052, RT3350: + - XTAL: 40 MHz. + - CPU: 320 or 384 MHz. + - BUS: CPU / 3 MHz. +* RT3352: + - XTAL: 40 MHz. + - CPU: 384 or 400 MHz. + - BUS: CPU / 3 MHz. + - PERIPH: 40 MHz. +* RT3383: + - XTAL: 40 MHz. + - CPU: 250, 384, 480 or 500 MHz. + - BUS: Depends on RAM Type and CPU: + + RAM DDR2: 125.
