We have to use ioctl numbers that don't collide with common code. Otherwise, these ones never even get called because the common fs code swalled all invocations. Reported-by: NKay Duenzer <kduenzer@maku.eu> Signed-off-by: NMike Frysinger <vapier@gentoo.org>

The RX/TX address is always the same regardless of the size of the access. That means there is no dedicated "16bit" or "32bit" MMR. Trying to use these currently leads to compile errors.

If the kernel's init section is merged back into the main memory region during boot (which it should since that is how we've laid out the kernel linker map), we want to make sure that these aren't counted as independent regions. Otherwise, if a large mapping is attempted which starts in the init region and extends into the main memory region, the access_ok func will deny it. This leads to weird messages during runtime like "unable to map xxx library" from the ldso but upon running the application again, everything works fine. So if the address of the end of the init region is the same as the start of the main memory region, simply enlarge the memory region to include the init region.

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.

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: NSonic Zhang <sonic.zhang@analog.com> Signed-off-by: NMike Frysinger <vapier@gentoo.org>

The predefined i2c address 0x2c doesn't match the configuration of the ad5280 PINs AD0 and AD1 on the tftlcd add-on board.

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: NMike Frysinger <vapier@gentoo.org>

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.

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.
