2009-12-13mfd: Disable unnecessary pcf50633 shutdown on lowsysPaul Fertser
On gta02 hardware revision A5 it can actually bring the system down during normal operating conditions so we disable it. Signed-off-by: Paul Fertser <fercerpav@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2009-12-13mfd: Convert WM835x IRQ handling to use a data tableMark Brown
Rather than open coding individual IRQs in each function which manipulates them store data for IRQs in a table which is then referenced in the users. This is a substantial code shrink and should be a performance win in cases where only a single IRQ goes off at once since instead of reading four of the second level IRQ registers for each interrupt we read only the sub-registers which have had an interrupt flagged.

2009-12-13mfd: Split wm8350 IRQ code into a separate fileMark Brown
In preparation for refactoring - it's over 700 lines of well-isolated code and having it in a file by itself makes things more managable. While we're at it make sure that we clean up the IRQ if we fail after acquiring it on init.

2009-12-13ARM: VFP: fix vfp thread init bug and document vfp notifier entry conditionsRussell King
When the VFP notifier is called for flush_thread(), we may be preemptible, meaning we might migrate to another CPU, which means referencing the current CPU number without some form of locking is invalid, and can cause data corruption. For the most cases, this isn't a problem since atomic notifiers are run under rcu lock, which for most configurations results in preemption being disabled - except when the preemptable tree-based rcu implementation is selected. Let's make it safe anyway. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2009-12-13spi: SuperH MSIOF SPI Master driver V2Magnus Damm
This patch is V2 of SPI Master support for the SuperH MSIOF. Full duplex, spi mode 0-3, active high cs, 3-wire and lsb first should all be supported, but the driver has so far only been tested with "mmc_spi". The MSIOF hardware comes with 32-bit FIFOs for receive and transmit, and this driver simply breaks the SPI messages into FIFO-sized chunks. The MSIOF hardware manages the pins for clock, receive and transmit (sck/miso/mosi), but the chip select pin is managed by software and must be configured as a regular GPIO pin by the board code. Performance wise there is still room for improvement, but on a Ecovec board with the built-in sh7724 MSIOF0 this driver gets Mini-sd read speeds of about half a megabyte per second. Future work include better clock setup and merging of 8-bit transfers into 32-bit words to reduce interrupt load and improve throughput.
