From 60ed7951d0c9bf8de8588384134f16474367b410 Mon Sep 17 00:00:00 2001 From: Alex Date: Mon, 17 Mar 2008 14:55:06 +0100 Subject: avr32: Allow board to define oscillator rates On our custom board we have other oscillator rates than on atngw100 and atstk100x. Currently these rates are hardcoded in arch/avr32/mach-at32ap/at32ap700x.c. This patch moves them into board specific code.

On AT32AP7000 the LCDC is wired to two sets of pins, which lets the user choose between dual ethernet and 32-bit EBI. For the ATNGW100 board it is vital to have the choice to select the alternative pinout since this pinout is routed to the external headers. Update ATSTK1002 and ATSTK1004 to use the new interface.

It should in theory work on AT91 systems too with some tweaking, but since the DMA interface is quite different, it's not entirely clear if it's worth merging this with the at91_mci driver. This driver has been around for a while in BSPs and kernel sources provided by Atmel, but this particular version uses the generic DMA Engine framework (with the slave extensions) instead of an avr32-only DMA controller framework. This driver can also use PIO transfers when no DMA channels are available, and for transfers where using DMA may be difficult or impractical for some reason (e.g. the DMA setup overhead is usually not worth it for very short transfers, and badly aligned buffers or lengths are difficult to handle.) Currently, the driver only support PIO transfers. DMA support has been split out to a separate patch to hopefully make it easier to review. The driver has been tested using mmc-block and ext3fs on several SD, SDHC and MMC+ cards. Reads and writes work fine, with read transfer rates up to 3.5 MiB/s on fast cards with debugging disabled. The driver has also been tested using the mmc_test module on the same cards. All tests except 7, 9, 15 and 17 succeed. The first two are unsupported by all the cards I have, so I don't know if the driver handles this correctly. The last two fail because the hardware flags a Data CRC Error instead of a Data Timeout error. I'm not sure how to deal with that.
