* Blackfin: boards: fix num_chipselect values for on-chip SPI busesMike Frysinger2010-10-222-3/+3
| | | | | | | | | 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>
* Blackfin: punt short SPI MMR bit namesMike Frysinger2010-10-221-45/+0
| | | | | | | Now that the common header defines everything and the SPI drivers are using it, we can drop these duplicated global namespace polluters. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: Rename IRQ flags handling functionsDavid Howells2010-10-071-4/+4
| | | | | | | | | | | | | | | Rename h/w IRQ flags handling functions to be in line with what is expected for the irq renaming patch. This renames local_*_hw() to hard_local_*() using the following perl command: perl -pi -e 's/local_irq_(restore|enable|disable)_hw/hard_local_irq_\1/ or s/local_irq_save_hw([_a-z]*)[(]flags[)]/flags = hard_local_irq_save\1()/' `find arch/blackfin/ -name "*.[ch]"` and then fixing up asm/irqflags.h manually. Additionally, arch/hard_local_save_flags() and arch/hard_local_irq_save() both return the flags rather than passing it through the argument list. Signed-off-by: David Howells <dhowells@redhat.com>
* Blackfin: Split PLL code from mach-specific cdef headersDavid Howells2010-10-072-50/+63
| | | | | | | Split the PLL control code from the Blackfin machine-specific cdef headers so that the irqflags functions can be renamed without incurring a header loop. Signed-off-by: David Howells <dhowells@redhat.com>
* Blackfin: punt duplicate SPORT MMR definesMike Frysinger2010-08-271-82/+0
| | | | | | | The common bfin_sport.h header now has unified definitions of these, so stop polluting the global namespace. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: unify rotary encoder bitmasksMike Frysinger2010-08-061-108/+0

* Blackfin: TWI: clean up the MMR namesMike Frysinger2010-08-061-18/+18
| | | | | | | | The standard short name for control is CTL and not CTRL. Use TWI0_xxx even on parts that only have one TWI bus to keep things simple. Drop all the cdef helpers since the bus driver takes care of everything. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: BF51x/BF52x: support GPIO Hysteresis/Schmitt Trigger optionsMichael Hennerich2010-08-062-0/+166
| | | | | | | | | Newer parts have optional Hysteresis/Schmitt Trigger options to help with dirty signals. So add some kconfig options for tuning this and enable it by default for people.

* Blackfin: gpio/portmux: clean up whitespace corruptionMike Frysinger2010-08-062-42/+42
| | | | | | | 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: 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 Frysinger2010-08-061-0/+1
| | | | | | | 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: add support for the on-chip MAC status interruptsMichael Hennerich2010-03-091-1/+10
| | | | | | | | | | | | | | | | | | | | | This patch provides infrastructure for MAC Wake-On-Lan and PHYINT use in phylib. New Interrupts added: IRQ_MAC_PHYINT /* PHY_INT Interrupt */ IRQ_MAC_MMCINT /* MMC Counter Interrupt */ IRQ_MAC_RXFSINT /* RX Frame-Status Interrupt */ IRQ_MAC_TXFSINT /* TX Frame-Status Interrupt */ IRQ_MAC_WAKEDET /* Wake-Up Interrupt */ IRQ_MAC_RXDMAERR /* RX DMA Direction Error Interrupt */ IRQ_MAC_TXDMAERR /* TX DMA Direction Error Interrupt */ IRQ_MAC_STMDONE /* Station Mgt. Transfer Done Interrupt */ On BF537/6 the implementation is not straight forward since there are now two chained chained_handlers. A cleaner approach would have been to add latter IRQs to the demux of IRQ_GENERIC_ERROR.

* Blackfin: move SPORT UART resources to boards filesSonic Zhang2010-03-091-0/+63
| | | | | | | | | | Rather than keeping the pins in the actual driver and worrying about a mess of Kconfig options, declare all the desired pin resources in the boards file. This lets people easily select the specific pins/ports for the normal emulated UART as well as GPIOs for CTS/RTS.

* Blackfin: push BF5Xx configs down into mach-specific KconfigsMike Frysinger2009-12-151-0/+4
| | | | | | | | While we're moving the BF54x code, have the BF54xM variants select the normal BF54x values so that the rest of the Kconfig tree doesn't need to check the BF54xM variant everytime it wants to check the BF54x. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: unify DMA masksMike Frysinger2009-12-151-34/+0

* Blackfin: mass clean up of copyright/licensing infoRobin Getz2009-10-0719-447/+45
| | | | | | | | | | | | | | | | | | Bill Gatliff & David Brownell pointed out we were missing some copyrights, and licensing terms in some of the files in ./arch/blackfin, so this fixes things, and cleans them up. It also removes: - verbose GPL text(refer to the top level ./COPYING file) - file names (you are looking at the file) - bug url (it's in the ./MAINTAINERS file) - "or later" on GPL-2, when we did not have that right It also allows some Blackfin-specific assembly files to be under a BSD like license (for people to use them outside of Linux).
