* [ARM] 5108/2: PXA SSP: Don't unconditionally free interruptMark Brown2008-07-10
| | | | | | | | | Callers may stop the SSP core requesting the interrupt so it can't be freed unconditionally. Also use NO_IRQ like we should.

* [ARM] pxa: add support for L2 outer cache on XScale3Eric Miao2008-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The initial patch from Lothar, and Lennert make it into a cleaner one, modified and tested on PXA320 by Eric Miao. This patch moves the L2 cache operations out of proc-xsc3.S into dedicated outer cache support code. CACHE_XSC3L2 can be deselected so no L2 cache specific code will be linked in, and that L2 enable bit will not be set, this applies to the following cases: a. _only_ PXA300/PXA310 support included and no L2 cache wanted b. PXA320 support included, but want L2 be disabled So the enabling of L2 depends on two things: - CACHE_XSC3L2 is selected - and L2 cache is present Where the latter is only a safeguard (previous testing shows it works OK even when this bit is turned on). IXP series of processors with XScale3 cannot disable L2 cache for the moment since they depend on the L2 cache for its coherent memory, so IXP may always select CACHE_XSC3L2. Other L2 relevant bits are always turned on (i.e. the original code enclosed by #if L2_CACHE_ENABLED .. #endif), as they showed no side effects. Specifically, these bits are: - OC bits in TTBASE register (table walk outer cache attributes) - LLR Outer Cache Attributes (OC) in Auxiliary Control Register Signed-off-by: Lothar WaÃ<9f>mann <LW@KARO-electronics.de> Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: Eric Miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Currently, they live side by side in pxa-regs.h, but only one set is available depending on the setting of PXA25x or PXA27x.

Remove these definitions from pxa-regs.h, and place them in separate files. Include these files where appropriate. Note: according to the dependencies in drivers/usb/gadget/Kconfig, we do not support the UDC on PXA27x nor PXA3xx CPUs, so remove the platform devices from pxa27x.c and pxa3xx.c.
