A few call sites inside mach-ixp4xx were still using the custom ixp4xx GPIO API with gpio_line_* accessors, convert all these to use the standard gpiolib functions instead. Also attempt to request and label all GPIOs before use. Move the GPIO requests to per-machine device_initcalls() so we are not dependent on the GPIO chip to be available at machine_init time.

Fix regression introduced by commit d2323cf7 ("onewire: w1-gpio: add ext_pullup_enable pin in platform data") which added a gpio entry to the platform data, but did not add the required initialisers to the board files using it. Consequently, the driver would request gpio 0 at probe, which could break other uses of the corresponding pin. On AT91 requesting gpio 0 changes the pin muxing for PIOA0, which, for instance, breaks SPI0 on at91sam9g20.

Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

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: NArnd Bergmann <arnd@arndb.de> Signed-off-by: NKrzysztof Hałasa <khc@pm.waw.pl>

As suggested by Andrew Morton: This is a pet peeve of mine. Any time there's a long list of items (header file inclusions, kconfig entries, array initalisers, etc) and someone wants to add a new item, they *always* go and stick it at the end of the list. Guys, don't do this. Either put the new item into a randomly-chosen position or, probably better, alphanumerically sort the list. lets sort all our select statements alphanumerically. This commit was created by the following perl: while (<>) { while (/\\\s*$/) { $_ .= <>; } undef %selects if /^\s*config\s+/; if (/^\s+select\s+(\w+).*/) { if (defined($selects{$1})) { if ($selects{$1} eq $_) { print STDERR "Warning: removing duplicated $1 entry\n"; } else { print STDERR "Error: $1 differently selected\n". "\tOld: $selects{$1}\n". "\tNew: $_\n"; exit 1; } } $selects{$1} = $_; next; } if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or /^endif/ or /^endchoice/)) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } undef %selects; } print; } if (%selects) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } } It found two duplicates: Warning: removing duplicated S5P_SETUP_MIPIPHY entry Warning: removing duplicated HARDIRQS_SW_RESEND entry and they are identical duplicates, hence the shrinkage in the diffstat of two lines.

Most PCI implementations use the standard PCI swizzle function, which handles the well defined behaviour of PCI-to-PCI bridges which can be found on cards (eg, four port ethernet cards.) Rather than having almost every platform specify the standard swizzle function, make this the default when no swizzle function is supplied. Therefore, a swizzle function only needs to be provided when there is something exceptional which needs to be handled. This gets rid of the swizzle initializer from 47 files, and leaves us with just two platforms specifying a swizzle function: ARM Integrator and Chalice CATS.

These were the ones I came across when building all defconfigs in arch/arm/configs, there might be more but they lack adequate build coverage to be easily caught.
