* ARM: 6124/1: ep93xx: SPI driver platform support codeMika Westerberg2010-05-13
| | | | | | | | | | | | | | | | | | This patch adds platform side support code for the EP93xx SPI driver. This includes clock, resources and muxing. There is a new function: ep93xx_register_spi() which can be used by board support code to register new SPI devices for the board. This patch depends on patch 5998/1 ep93xx: added chip revision reading function Cc: Ryan Mallon <ryan@bluewatersys.com> Cc: David Brownell <dbrownell@users.sourceforge.net> Cc: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Mika Westerberg <mika.westerberg@iki.fi> Acked-by: H Hartley Sweeten <hsweeten@visionengravers.com> Acked-by: Martin Guy <martinwguy@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* ARM: 5992/1: ep93xx: pass platform startup data as __initdataHartley Sweeten2010-04-14
| | | | | | | | | | | | | | | | | | | | | | | A number of the peripherals for the ep93xx are registered at startup using platform_data that is passed from the board init code to the core code. This data is then copied to a local static variable in the core code. Since the data is copied, the original data can be marked as __initdata and discarded after startup is complete. This adds the __initdata tag to all the appropriate data in the various ep93xx board init's. Specifically, all the struct ep93xx_eth_data, struct ep93xxfb_mach_info, and struct i2c_gpio_platform_data. Also, document the various registration functions and note what data should be marked as __initdata. While here, also cleanup a couple over zealous whitespace tabs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | reg_cacheretrieved register values The MsBSP register cache will never have any error/status flags set, since these flags are never written to the reg_cache. So it is kind of not necessary to clear these flags, which are actually always 0. In other words, clearing the status/error flags are not necessary, since the reg_cache will never got these bits set. We can just write back the register content from the cache as it is when clearing an error condition. Tested on Amstrad Delta.

| * OMAP4: fix temporary hacks that break multi-omap PMKevin Hilman2010-03-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building for multi-omap, and OMAP4 is enabled, CONFIG_ARCH_OMAP4 will be true and prevent included code from building/running for OMAP2/3 as well. This problem exists in io.c where some hwmod/PM/SDRC init code is prevented from running even on OMAP2/3 when OMAP4 is included in a multi-OMAP build. A quick glance suggests that this #ifndef is no longer needed in most of the cases. In the remaining cases, the function is wrapped with "if (cpu_is_omap24xx() || cpu_is_omap34xx())" which will be optimized out for OMAP4-only builds. Note that this is only a short-term fix. Longer-term, OMAP4 needs to create init functions for SDRC and hwmod late-init.

| * OMAP2: cpu_is_omap2*: fix compile-time removal of unused codeKevin Hilman2010-03-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently if omap2420 is defined but not omap2430, cpu_is_omap2430() is still defined as a macro, instead of #define'd to zero. This results in conditional cpu_is_omap2430() code still being compiled, and leads to possible compile/link errors. In particular for hwmod init. To fix, add extra #ifdefs to CPU check macros to ensure that the is_omap* macros are zero for each OMAP2 if they are not configured into the kernel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch follows the commit be093beb608edf821b45fe00a8a080fb5c6ed4af by Russell King: OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). The patch adds the missing parameter to omap1_arch_reset() and omap_prcm_arch_reset(), and modifies the latter to pass the reboot command parameter to the boot loader instead of reboot mode (which is for kernel internal use only and cannot be modified by the userspace).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent DMA API changes broke compile for tusb6010. While testing the fixes for tusb6010, I had to update the n8x0 defconfig quite a bit. Might as well merge it while at it to make it more usable as we're using this to test the multi-omap booting between V6 and V7 ARMs. Also, anybody using n8x0 with a current kernel will most likely want to mount root on the MMC instead of the onenand to keep the Maemo install intact.

The non-mmu pgtable support code also needs to implement this macro, otherwise when compiling you get: CC arch/arm/mm/dma-mapping.o arch/arm/mm/dma-mapping.c: In function 'dma_alloc_coherent': arch/arm/mm/dma-mapping.c:320: error: implicit declaration of function 'pgprot_dmacoherent' arch/arm/mm/dma-mapping.c:320: error: 'pgprot_kernel' undeclared (first use in this function) arch/arm/mm/dma-mapping.c:320: error: (Each undeclared identifier is reported only once arch/arm/mm/dma-mapping.c:320: error: for each function it appears in.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2.6.34-rc1 added kernel/elfcore.c which includes <asm/elf.h>. On ARM, this results in: In file included from include/linux/elf.h:7, from kernel/elfcore.c:1: /tmp/linux-2.6.34-rc1/arch/arm/include/asm/elf.h:101: warning: 'struct task_struct' declared inside parameter list /tmp/linux-2.6.34-rc1/arch/arm/include/asm/elf.h:101: warning: its scope is only this definition or declaration, which is probably not what you want Including <linux/sched.h> seems a bit heavyweight, so this patch just adds a tentative declaration of struct task_struct in <asm/elf.h>.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The change introduced in patch 5596/1 used incorrect bracing which resulted in the AT24 EEPROM no longer being registered. This patch corrects the bracing and allows both the WM8731 audio device and AT24 EEPROM device to be registered.

Fix this by moving the declaration into uncompress/misc.c where it is shared with the rest of the code, correcting the definition as we go.
