2009-12-15locking: Convert raw_rwlock to arch_rwlockThomas Gleixner3-7/+7
Not strictly necessary for -rt as -rt does not have non sleeping rwlocks, but it's odd to not have a consistent naming convention. No functional change.

2009-12-15locking: Convert raw_spinlock to arch_spinlockThomas Gleixner5-12/+12
The raw_spin* namespace was taken by lockdep for the architecture specific implementations. raw_spin_* would be the ideal name space for the spinlocks which are not converted to sleeping locks in preempt-rt. Linus suggested to convert the raw_ to arch_ locks and cleanup the name space instead of using an artifical name like core_spin, atomic_spin or whatever No functional change.

This fixes several things while still providing the old API: - simplify and fix locking - better error handling - don't ack all irqs making it impossible to detect a reset of the rtc - use a timeout variant to wait for completion of ADC conversion - provide platform-data to regulator subdevice (This allows making struct mc13783 opaque for other drivers after the regulator driver is updated to use its platform_data.) - expose all interrupts - use threaded irq After all users in mainline are converted to the new API, some things (e.g. mc13783-private.h) can go away.

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.

2009-12-13spi: SuperH MSIOF SPI Master driver V2Magnus Damm1-0/+10
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.
