arm: Add support for programmable oscillators
Review Request #2943 - Created July 7, 2015 and submitted
Changeset 10922:77159b449464 --------------------------- arm: Add support for programmable oscillators Add support for oscillators that can be programmed using the RealView / Versatile Express configuration interface. These oscillators are typically used for things like the pixel clock in the display controller. The default configurations support the oscillators from a Versatile Express motherboard (V2M-P1) with a CoreTile Express A15x2.
Tested with a modified HDLCD controller hooked up to osc_pxl and fbset in Linux. Pixel clock set as expected.
