From dc2eb76c40590a3c080294d1fbd000c8f70d88a9 Mon Sep 17 00:00:00 2001 From: Cyril Chemparathy Date: Tue, 18 May 2010 12:51:17 -0400 Subject: Davinci: generalized debug macros This patch adopts a debug uart selection similar to the OMAP model. During the boot process, the uncompress code determines the physical and virtual base addresses of the board-specific debug uart. These addresses are then passed on to the in-kernel debug macros through a small chunk of memory placed just below the page tables (@0x80003ff8).

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().

Key differences between davinci and tnetv107x controllers: - register map - davinci's controller is organized into banks of 32 gpios, tnetv107x has a single space with arrays of registers for in, out, direction, etc. - davinci's controller has separate set/clear registers for output, tnetv107x has a single direct mapped register. This patch does not yet add gpio irq support on this controller.

Doing so helps catch errors of the sort where the resource structure has information for more channel controllers than the number channel controller info structures defined. Such insufficient platform data would lead to illegal memory accesses.

If a channel/slot is allocated from DSP, the existing EDMA driver can still allocate the same resource on ARM. This patch enables the user to pass the channel/slots reserved for DSP as platform data. EDMA driver scans this list during probe and prepares a bitmap of channel/slots which can be used on ARM side. Trying to reserve channels by doing a 'pre-allocate' using edma_alloc_{slot|channel}() API does not work because 1) The reservation should be done in probe() to avoid race with other ARM side driver trying to use EDMA 2) The alloc channel API sets up the access through shadow region 0 which will be incorrect for DSP usage. It also sets up the channel <-> queue number mapping which is not required as DSP will likely do its own mapping anyway. 3) (minor) There is no API to allocate channels in bulk.
