| * [ARM] make page_to_dma() highmem awareNicolas Pitre2009-03-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a machine class has a custom __virt_to_bus() implementation then it must provide a __arch_page_to_dma() implementation as well which is _not_ based on page_address() to support highmem. This patch fixes existing __arch_page_to_dma() and provide a default implementation otherwise. The default implementation for highmem is based on __pfn_to_bus() which is defined only when no custom __virt_to_bus() is provided by the machine class. That leaves only ebsa110 and footbridge which cannot support highmem until they provide their own __arch_page_to_dma() implementation. But highmem support on those legacy platforms with limited memory is certainly not a priority. Signed-off-by: Nicolas Pitre <nico@marvell.com>
* | [ARM] pass reboot command line to arch_reset()Russell King2009-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.

| | | | | | | | | | | | | | This patch is as small a change as possible to the KS8695 GPIO layer to use GPIOLIB to allow the generic GPIO expanders and the like to be compiled. As a side-effect, we also remove __init_or_module from several functions which could be called by drivers such as i2c-gpio which could plausibly be compiled into a non-modular kernel.

* [ARM] KS8695: Fix up device registration.Daniel Silverstone2008-12-14
| | | | | | | | | | | | | | The KS8695 device.c provides registration functionality for the KS8695's various devices such as watchdog timers and ethernet devices. Rather than predicating those on the config options for the drivers, always register the platform devices so that a later built module can hook on. Also, the ethernet used to register virtual addresses in the platform data. This is wrong and so this patch changes them to physical addresses and also passes in the appropriate physical region for the PHY or Switch as appropriate.

* [ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King2008-11-29
| | | | | | | | | | | | | When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.

* [ARM] remove a common set of __virt_to_bus definitionsNicolas Pitre2008-11-28
| | | | | | | | | | | | | | | | Let's provide an overridable default instead of having every machine class define __virt_to_bus and __bus_to_virt to the same thing. What most platforms are using is bus_addr == phys_addr so such is the default. One exception is ebsa110 which has no DMA what so ever, so the actual definition is not important except only for proper compilation. Also added a comment about the special footbridge bus translation. Let's also remove comments alluding to set_dma_addr which is not (and should not) be commonly used.
