2009-04-23ARM: OMAP: Fix for possible race condition in omap_free_dma()Santosh Shilimkar
Fix the possible race condition in omap_free_dma(). Function omap_free_dma() sets the dev_id = -1 and then accesses the channel afterwards to clear it. But setting the dev_id=-1 makes the channel available for allocation again. So it is possible someone else can grab it and results are unpredictable. To avod this DMA channle is cleared first and then the dev_id = -1 is set. Thanks to McNeil, Sean <sean.mcneil@ti.com> for ointing out this issue.

2009-04-23davinci: add arch_ioremap() which uses existing static mappingsKevin Hilman
Add arch-specific ioremap() which uses any existing static mappings in place of doing a new mapping. From now on, drivers should always use ioremap() instead of IO_ADDRESS(). In addition, remove the davinci_[read|write]* macros in favor of using ioremap. Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2009-04-23davinci: major rework of clock, PLL, PSC infrastructureKevin Hilman
This is a significant rework of the low-level clock, PLL and Power Sleep Controller (PSC) implementation for the DaVinci family. The primary goal is to have better modeling if the hardware clocks and features with the aim of DVFS functionality. Highlights: - model PLLs and all PLL-derived clocks - model parent/child relationships of PLLs and clocks - convert to new clkdev layer - view clock frequency and refcount via /proc/davinci_clocks Special thanks to significant contributions and testing by David Brownell.

2009-04-22OMAP2xxx clock: pre-initialize struct clks earlyPaul Walmsley
Commit 3f0a820c4c0b4670fb5f164baa5582e23c2ef118 breaks OMAP2xxx boot during initial propagate_rate() on osc_ck and sys_ck. Fix by pre-initializing all struct clks before running any other clock init code. Incorporates review comments from Russell King <rmk+kernel@arm.linux.org.uk>.

2009-04-20[ARM] 5456/1: add sys_preadv and sys_pwritevMikael Pettersson
Kernel 2.6.30-rc1 added sys_preadv and sys_pwritev to most archs but not ARM, resulting in <stdin>:1421:2: warning: #warning syscall preadv not implemented <stdin>:1425:2: warning: #warning syscall pwritev not implemented This patch adds sys_preadv and sys_pwritev to ARM. These syscalls simply take five long-sized parameters, so they should have no calling-convention/ABI issues in the kernel. Tested on armv5tel eabi using a preadv/pwritev test program posted on linuxppc-dev earlier this month. It would be nice to get this into the kernel before 2.6.30 final, so that glibc's kernel version feature test for these syscalls doesn't have to special-case ARM.

2009-04-16[ARM] 5455/1: Fix IRQ noise from VIC codeLinus Walleij
The VIC code will attempt to perform som default set_irq_chip() and set_irq_chip_data() on all IRQs supported by the VIC, while the new IRQ handling code strictly checks for the global NR_IRQS to be respected also for these IRQs. This patch will respect the interrupt mask passed to the VIC driver and will prevent it from attempting to call these functions on any unused interrupts.
