* ARM: Realview/Versatile: separate out common sched_clock()Russell King2010-05-024-38/+55
| | | | | | | Provide a common sched_clock() implementation for Versatile and Realview. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: Integrator: move 16-bit timer support to Integrator/APRussell King2010-05-024-163/+155
| | | | | | | Only Integrator/AP has 16-bit timers, so move the support into the Integrator/AP specific support files. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: Integrator: convert Integrator/CP to use SP804 timer supportRussell King2010-05-022-2/+13
| | | | | | | The Integrator/CP board has SP804-compatible timer modules, so use the SP804-compatible code from Versatile and Realview. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* ARM: Realview/Versatile: remove useless TIMER_RELOAD calculationsRussell King2010-05-021-11/+1
| | | | | | | | | | | | | | | | | | Realview/Versatile copied the Integrator timer code, including the calculations for ensuring that the reload value fits into the 16-bit counter. However, these platforms have a 32-bit counter which is clocked at a slower rate. The result is that the preprocessor conditions are never triggered: TICKS_PER_uSEC = 1, mSEC_10 = 10000, which is 0x2710 - less than 0x10000. So, remove the unnecessary complexity, reducing the TIMER_RELOAD calculation to just: TICKS_PER_uSEC * mSEC_10 Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* ARM: ICST: kill duplicate icst codeRussell King2010-05-0220-218/+67
| | | | | | | | The only difference between ICST307 and ICST525 are the two arrays for calculating the S parameter; the code is now identical. Merge the two files and kill the duplicated code. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | This makes the ICST support fit more nicely with the clk API, eliminating the need to *1000 and /1000 in places. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* ARM: ICST: icst.*_ps_to_vco() functions are unused, remove themRussell King2010-05-024-131/+0
| | | | | | | | These functions were originally implemented for the CLCD driver before we had clk API support. Since the CLCD driver does not use these anymore, we can remove them. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: ICST: merge common ICST VCO structuresRussell King2010-05-0216-76/+85
| | | | | | | The structures for the ICST307 and ICST525 VCO devices are identical, so merge them together. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | Realview doesn't include mach/platform.h in mach/hardware.h, so make versatile behave in the same way. Also, move the definition of __io_address() into mach/hardware.h, just like Realview. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | The exact hardware error handling code was added before the workaround for anomaly 283 which caused the anomaly to be triggered in some cases (an infinite core stall).

| * Blackfin: don't support keypad wakeup from hibernateMichael Hennerich2010-03-091-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The on-chip keypad peripheral requires different registers to be setup depending on the standby type (standby vs hibernation). However, since the power management framework doesn't differentiate between these types, the driver doesn't know which registers to program and subsequently it avoids doing so. Always enabling the keyboard wakeup source causes misbehavior when the pins are not assigned to the keypad. If they happen to drive a certain level, they'll trigger a wake up event which is not wanted. So until the aforementioned issue can be sorted out, drop support for the wakeup source completely.

| * Blackfin: add support for the on-chip MAC status interruptsMichael Hennerich2010-03-094-7/+166
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: fix single stepping over system callsMike Frysinger2010-03-094-3/+15
| | | | | | | | | | | | | | | | | | | | | | | | On Blackfin systems, the hardware single step exception triggers before the system call exception, so we need to save this info to process it later on. Otherwise, single stepping in userspace misses a few insns right after the system call. This is based a bit on the SuperH code added in commit 4b505db9c4c72dbd.
