Davinci: tnetv107x soc support
TNETV107X is a Texas Instruments SOC that shares a number of common features with the Davinci architecture. Some of the key differences between traditional Davincis and this new SOC are as follow: 1. The SOCs clock architecture includes a new spread-spectrum PLL. Some elements of the clock architecture are reused from Davinci (e.g. LPSC), but the PLL related code is overridden using existing interfaces in "struct clk". 2. The MMR layout on this SOC is substantially different from Davinci. Consequently, the fixed I/O map is a whole lot more convoluted (more so than DA8xx). The net impact here is that IO_ADDRESS() will not work on this SoC, and therefore all mappings have to be through ioremap().

608 * TNETV107X platforms do not use the static mappings from Davinci
609 * IO_PHYS/IO_VIRT. This SOC's interesting MMRs are at different addresses,
610 * and changing IO_PHYS would break away from existing Davinci SOCs.
611 *
612 * The primary impact of the current model is that IO_ADDRESS() is not to be
613 * used to map registers on TNETV107X.
614 *
615 * 1. The first chunk is for INTC: This needs to be mapped in via iotable
616 * because ioremap() does not seem to be operational at the time when
617 * irqs are initialized. Without this, consistent dma init bombs.
618 *
619 * 2. The second chunk maps in register areas that need to be populated into
620 * davinci_soc_info. Note that alignment restrictions come into play if
621 * low-level debug is enabled (see note in <mach/tnetv107x.h>).
