Re: Request for SPI testing
Hi Grant, I've pushed out Ernst's spi bus locking API patches to the following branch. Before I push them into linux-next, I'd like to get some testing. Can I have some volunteers please to pull this branch and give it a spin? Bonus points for people who have mmc cards multiplexed with other devices on their SPI bus. Thanks for bringing up this topic. We are working with these two patches (except the spin_lock_irqsave modification and the 'bool' datatype for bus_lock_flag) for several months on our system (powerpc, MPC8314, kernel 2.6.32.7 and 2.6.32.14) that makes heavy use of several SPI devices: 9 x EEPROM, 3 x dataflash, MMC and 2 x MDIO-pseudo-SPI (with a special SPI-to-MDIO bus driver). The MMC is used rarely, but the rest is essential for system operation. Until now, we observed no problems, even when copying EEPROM data to MMC. So you may add my 'tested-by'.

I put these patches through some light testing by reading data from a flash device and writing it to an mmc card, both over SPI. They seem to hold up fine, but I can certainly try some other things if you have anything specific in mind. -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
Request for SPI testing
