2009-12-17cs5535: CS5535_MFGPT_DEFAULT_IRQ should depend on CS5535_MFGPTGeert Uytterhoeven

2009-12-17x86: Reenable TSC sync check at boot, even with NONSTOP_TSCPallipadi, Venkatesh
Commit 83ce4009 did the following change If the TSC is constant and non-stop, also set it reliable. But, there seems to be few systems that will end up with TSC warp across sockets, depending on how the cpus come out of reset. Skipping TSC sync test on such systems may result in time inconsistency later. So, reenable TSC sync test even on constant and non-stop TSC systems. Set, sched_clock_stable to 1 by default and reset it in mark_tsc_unstable, if TSC sync fails. This change still gives perf benefit mentioned in 83ce4009 for systems where TSC is reliable.

2009-12-17spi: Add s3c64xx SPI Controller driverJassi Brar
Each SPI controller has exactly one CS line and as such doesn't provide for multi-cs. We implement a workaround to support multi-cs by _not_ configuring the mux'ed CS pin for each SPI controller. The CS mechanism is assumed to be fully machine specific - the driver doesn't even assume some GPIO pin is used to control the CS. The driver selects between DMA and POLLING mode depending upon the xfer size - DMA mode for xfers bigger than FIFO size, POLLING mode otherwise. The driver has been designed to be capable of running SoCs since s3c64xx and till date, for that reason some of the register fields have been passed via, SoC specific, platform data.

2009-12-17atmel_spi: fix dma addr calculation for len > BUFFER_SIZEBen Nizette
If len > BUFFER_LEN and !xfer->rx_buf we end up calculating the tx buffer address as *tx_dma = xfer->tx_dma + xfer->len - BUFFER_SIZE; which is constant; i.e. we just send the last BUFFER_SIZE data over again until we've reached the right number of bytes. This patch gets around this by using the /requested/ length when calculating addresses. Note there's no way len != *plen when we calculate the rx buffer address but conceptually we should be using *plen and I don't want someone to come through later, see the calculations for rx and tx are different and "clean up" back to what we had.

2009-12-17spi_s3c24xx: add FIQ pseudo-DMA supportBen Dooks
Add pseudo-DMA by FIQ to the S3C24XX SPI driver. This allows the driver to get DMA-like performance where there are either no free DMA channels or when doing transfers that required both TX and RX data paths. Since this patch requires the addition of an assembly file to hold the FIQ code, we rename the module (instead of adding a rename of the .c file to this patch). We expect most users are loading this via udev and thus there should be no change to the userland configuration.
