2010-10-22Blackfin: gpio: add peripheral group checksteven miao
Many Blackfin parts group sets of pins into a single functional unit. This means you cannot use different pins within a group for different peripherals. Our resource conflict checking thus far has been limited to individual pins, so if someone tried to grab a different pin from the same group, it would be allowed while silently changing the other pins in the same group. One common example is the pin set PG12 - PG15 on BF51x parts. They may either be used with SPI0 (1st function), or they may be used with PTP/PWM/AMS3 (3rd function). Ideally, we'd like to use PG12 - PG14 for SPI0 while using PG15 with AMS3, but the hardware does not permit this. In the past, the software would allow the pins to be requested this way, but ultimately things like the Blackfin SPI driver would stop working when the hardware rerouted to a different peripheral.

2010-10-22Blackfin: add new cacheflush syscallSonic Zhang
Flushing caches sometimes requires anomaly workarounds which require supervisor-only insns. Normally we don't need to flush caches from userspace so this isn't a problem, but when gcc generates trampolines on the stack, we do. So add a new syscall for gcc to use modeled after the mips version. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-10-22Blackfin: bf537-stamp: tweak i2c address for ad5280 add-on tftlcd boardSonic Zhang
The predefined i2c address 0x2c doesn't match the configuration of the ad5280 PINs AD0 and AD1 on the tftlcd add-on board. Both AD0 and AD1 are of voltage 3.3V, which means the i2c address should be 0x2F. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-10-22Blackfin: workaround anomaly 05000481 (corruption with ITEST MMRs)Robin Getz
Nothing actually needs to use these MMRs (as direct cache manipulation is done with the DTEST MMRs), so simply hide the read funcs behind the anomaly define.

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: 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.
