2012-11-22IXP4xx: use __iomem for MMIOArnd Bergmann1-2/+2
The ixp4xx queue manager uses "const struct qmgr_regs __iomem *" as the type for a pointer that is passed to __raw_writel, which is not allowed because of the const-ness. Dropping the 'const' keyword fixes the problem. While we're here, let's also drop the useless type cast. Without this patch, building ixp4xx_defconfig results in: In file included from arch/arm/mach-ixp4xx/ixp4xx_qmgr.c:15:0: arch/arm/mach-ixp4xx/include/mach/qmgr.h: In function 'qmgr_put_entry': arch/arm/mach-ixp4xx/include/mach/qmgr.h:96:2: warning: passing argument 2 of '__raw_writel' discards 'const' qualifier from pointer target type [enabled by default] arch/arm/include/asm/io.h:88:91: note: expected 'volatile void *' but argument is of type 'const u32 *' In file included from drivers/net/ethernet/xscale/ixp4xx_eth.c:41:0: arch/arm/mach-ixp4xx/include/mach/qmgr.h: In function 'qmgr_put_entry': arch/arm/mach-ixp4xx/include/mach/qmgr.h:96:2: warning: passing argument 2 of '__raw_writel' discards 'const' qualifier from pointer target type [enabled by default] arch/arm/include/asm/io.h:88:91: note: expected 'volatile void *' but argument is of type 'const u32 *' arch/arm/mach-ixp4xx/ixp4xx_qmgr.c: In function 'qmgr_set_irq': arch/arm/mach-ixp4xx/ixp4xx_qmgr.c:41:9: warning: passing argument 2 of '__raw_writel' discards 'const' qualifier from pointer target type [enabled by default] arch/arm/include/asm/io.h:88:91: note: expected 'volatile void *' but argument is of type 'const u32 *' Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Krzysztof Hałasa <khc@pm.waw.pl>
2012-11-22IXP4xx: Always ioremap() Queue Manager MMIO region at boot.Krzysztof Hałasa1-12/+2
It doesn't make much sense to map QMgr dynamically - we almost always need it and the static mapping will be needed for little-endian data-coherent operation (to make QMgr region value-coherent). Signed-off-by: Krzysztof Hałasa <khc@pm.waw.pl>
2011-02-06IXP4xx: Fix qmgr_release_queue() flushing unexpected queue entries.Krzysztof Hałasa1-4/+5
Queues should be empty when released, if not, there is a safety valve. Make sure the queue is usable after it triggers. Signed-off-by: Krzysztof Hałasa <khc@pm.waw.pl>
