2010-10-22Blackfin: i2c-gpio boards: use GPIO_PF# definesMike Frysinger
Rather than use raw numbers for the GPIO pins, use proper GPIO defines. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-10-22Blackfin: access_ok: permit L1 stackBarry Song
When apps run with their stack in L1, some system calls might be made where a buffer is in the stack as an argument. So make sure the core Blackfin access code does not reject this memory location. Signed-off-by: Barry Song <barry.song@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-10-22Blackfin: boards: fix num_chipselect values for on-chip SPI busesMike Frysinger
The num_chipselect field for on-chip Blackfin SPI buses is supposed to be 1 larger than the number of actual CSs available. This is because the hardware starts counting at 1 and not 0. There is a field for "CS0", but it is marked as "reserved" everywhere. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-10-22Blackfin: SIC: BF537: change default data/error relative prioritiesMichael Hennerich
Some peripherals might generate an error interrupt shortly after the data interrupt due to the fact that the peripheral isn't serviced fast enough. In most cases this isn't a problem and is expected behavior. This hasn't been a problem on most parts since you simply don't request the error interrupt (or you leave it disabled while there is an expected state) and do the peripheral status checking in the data interrupt. The Blackfin SIC allows people to prioritize data and error interrupts, and the Blackfin CEC allows interrupts of equal or higher priority to nest. The current default settings gives error interrupts a higher priority than data interrupts. So if an error occurs while processing the data interrupt, it will be serviced immediately. However, the error interrupt on the BF537 SIC cannot be enabled on a per-peripheral basis. Once the error interrupt is enabled for one peripheral, it is automatically enabled for all peripherals. Therefore lower the default multiplexed error interrupt priority so most people need not worry themselves with this issue.

2010-10-22Blackfin: bf537-stamp: fix NAND resourcesMike Frysinger

2010-10-22Blackfin: boards: use proper irq flags with isp1362-hcdMichael Hennerich
With the recent kernel update the isp1362-hcd driver evaluates the IORESOURCE_IRQ resource flags and requests the irq with the given polarity/edge settings. However the ISP1362 config requires low level/edge interrupts. Most of the Blackfin boards use some random flag or no flag at all. Make all boards use a know good flag IORESOURCE_IRQ_LOWEDGE.

ATA devices don't send D2H Reg FIS after an successful ATA PIO data-in command. The host is supposed to take the TF and E_Status of the preceding PIO Setup FIS. Update ahci_qc_fill_rtf() such that it takes TF + E_Status from PIO Setup FIS after a successful ATA PIO data-in command. Without this patch, result_tf for such a command is filled with the content of the previous D2H Reg FIS which belongs to a previous command, which can make the command incorrectly seen as failed. * Patch updated to grab the whole TF + E_Status from PIO Setup FIS instead of just E_Status as suggested by Robert Hancock.
