* Blackfin: gpio/portmux: clean up whitespace corruptionMike Frysinger2010-08-0615-323/+323
| | | | | | | Random tabs instead of spaces, mixes of the two, and unicode spaces instead of ascii spaces. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: make sure mmiowb inserts a write barrier with SSYNCMichael Hennerich2010-08-061-1/+7
| | | | | | | | | Add SSYNC to our implementation of I/O write barrier to ensure ordering of I/O space writes. This will make sure that writes following the barrier will arrive after all previous writes.

* Blackfin: fix DMA/cache bug when resuming from suspend to RAMMichael Hennerich2010-08-063-10/+27
| | | | | | | | | | | | The dma_memcpy() function takes care of flushing different caches for us. Normally this is what we want, but when resuming from mem, we don't yet have caches enabled. If these functions happen to be placed into L1 mem (which is what we're trying to relocate), then things aren't going to work. So define a non-cache dma_memcpy() variant to utilize in situations like this. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: BF51x: fix handling of PH8 (the "internal" SPI0SEL4 pin)Mike Frysinger2010-08-062-2/+3
| | | | | | | | Even though the PH8 pin is only internal to the processor packaging, it can be controlled like any other GPIO pin. Now that we have a proper GPIO define, we can fix the SPI0 CS4 define for the internal SPI flash. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: add a GPIO_DEFAULT_BOOT_SPI_CSMike Frysinger2010-08-067-0/+7
| | | | | | | This is parallel to the existing P_DEFAULT_BOOT_SPI_CS, but in terms of the GPIO value so it can be used with the normal gpio API. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: allow cache funcs to be in L1 for IFLUSH Anomaly 05000491Mike Frysinger2010-08-063-11/+20
| | | | | | | | | | | | | | Anomaly 05000491 says that IFLUSH cannot have certain types of memory stalls triggered before it has completed in order to function correctly. One such condition is that it be in L1 instruction. So add a config option to move it there, default it to on, and throw up a warning when it is turned off and this anomaly exists. Since the anomaly should be worked around, we can drop the older method of calling IFLUSH multiple times.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the declaration of of_get_address(), of_get_pci_address(), and of_pci_address_to_resource() out of arch code and into the common linux/of_address header file. This patch also fixes some of the asm/prom.h ordering issues.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of_platform_bus was being used in the same manner as the platform_bus. The only difference being that of_platform_bus devices are generated from data in the device tree, and platform_bus devices are usually statically allocated in platform code. Having them separate causes the problem of device drivers having to be registered twice if it was possible for the same device to appear on either bus. This patch removes of_platform_bus_type and registers all of_platform bus devices and drivers on the platform bus instead. A previous patch made the of_device structure an alias for the platform_device structure, and a shim is used to adapt of_platform_drivers to the platform bus. After all of of_platform_bus drivers are converted to be normal platform drivers, the shim code can be removed. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch tightens up the behaviour of of_modalias_node() to be more predicatable and to eliminate the explicit of_modalias_tablep[] that is currently used to override the first entry in the compatible list of a device. The override table was needed originally because spi and i2c drivers had no way to do of-style matching. Now that all devices can have an of_node pointer, and all drivers can have an of_match_table, the explicit override table is no longer needed because each driver can specify its own OF-style match data. The mpc8349emitx-mcu driver is modified to explicitly specify the correct device to bind against. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
