| * [PATCH] spi: simple SPI frameworkDavid Brownell2006-01-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the core of a small SPI framework, implementing the model of a queue of messages which complete asynchronously (with thin synchronous wrappers on top). - It's still less than 2KB of ".text" (ARM). If there's got to be a mid-layer for something so simple, that's the right size budget. :) - The guts use board-specific SPI device tables to build the driver model tree. (Hardware probing is rarely an option.) - This version of Kconfig includes no drivers. At this writing there are two known master controller drivers (PXA/SSP, OMAP MicroWire) and three protocol drivers (CS8415a, ADS7846, DataFlash) with LKML mentions of other drivers in development. - No userspace API. There are several implementations to compare. Implement them like any other driver, and bind them with sysfs. The changes from last version posted to LKML (on 11-Nov-2005) are minor, and include: - One bugfix (removes a FIXME), with the visible effect of making device names be "spiB.C" where B is the bus number and C is the chipselect. - The "caller provides DMA mappings" mechanism now has kerneldoc, for DMA drivers that want to be fancy. - Hey, the framework init can be subsys_init. Even though board init logic fires earlier, at arch_init ... since the framework init is for driver support, and the board init support uses static init. - Various additional spec/doc clarifications based on discussions with other folk. It adds a brief "thank you" at the end, for folk who've helped nudge this framework into existence. As I've said before, I think that "protocol tweaking" is the main support that this driver framework will need to evolve.

| * [ARM] Allow r2 to be passed through the decompressor to the kernelRussell King2006-01-121-21/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is part of a patch from Marc Singer to allow r2 to be passed to the kernel. Marc's original comments follow: This revised R2 (atags pointer) patch incorporates comments from Nico Pitre and Ben Dooks. It modifies the head.S files such that the R2 value set by the bootloader is conveyed to the kernel startup code. The kernel head.S heuristically validates the pointer. It will set R2 to zero if it believes the pointer is invalid. Presently, it requires that the ATAGS list reside in the first 16KiB of physical RAM. Relaxing this contraint may be both desirable as well as tricky. Signed-off-by: Marc Singer <elf@buici.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * [ARM] 3256/1: Make the function-returning ldm's use sp as the base registerCatalin Marinas2006-01-124-11/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Catalin Marinas If the low interrupt latency mode is enabled for the CPU (from ARMv6 onwards), the ldm/stm instructions are no longer atomic. An ldm instruction restoring the sp and pc registers can be interrupted immediately after sp was updated but before the pc. If this happens, the CPU restores the base register to the value before the ldm instruction but if the base register is not sp, the interrupt routine will corrupt the stack and the restarted ldm instruction will load garbage. Note that future ARM cores might always run in the low interrupt latency mode. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Deepak Saxena In working on adding 36-bit addressed supersection support to ioremap(), I came to the conclusion that it would be far simpler to do so by just splitting __ioremap() into a main external interface and adding an __ioremap_pfn() function that takes a pfn + offset into the page that __ioremap() can call. This way existing callers of __ioremap() won't have to change their code and 36-bit systems will just call __ioremap_pfn() and we will not have to deal with unsigned long long variables. Note that __ioremap_pfn() should _NOT_ be called directly by drivers but is reserved for use by arch_ioremap() implementations that map 32-bit resource regions into the real 36-bit address and then call this new function.

| * [PATCH] IRQ type flagsRussell King2006-01-086-19/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some ARM platforms have the ability to program the interrupt controller to detect various interrupt edges and/or levels. For some platforms, this is critical to setup correctly, particularly those which the setting is dependent on the device. Currently, ARM drivers do (eg) the following: err = request_irq(irq, ...); set_irq_type(irq, IRQT_RISING); However, if the interrupt has previously been programmed to be level sensitive (for whatever reason) then this will cause an interrupt storm. Hence, if we combine set_irq_type() with request_irq(), we can then safely set the type prior to unmasking the interrupt. The unfortunate problem is that in order to support this, these flags need to be visible outside of the ARM architecture - drivers such as smc91x need these flags and they're cross-architecture. Finally, the SA_TRIGGER_* flag passed to request_irq() should reflect the property that the device would like. The IRQ controller code should do its best to select the most appropriate supported mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Deepak Saxena The expansion bus on the IXP46x NPU can be configured for either 32MiB or 16MiB windows and changing the configuration causes the base address for each chip select for each region to change. Because of this, we cannot hardcode the physical base as we currently do. This patch checks the expansion bus configuration registers at runtime to determine the appropriate window size. Note that this requires that the bootloader already configured the device sizes appropriately, but I feel that is valid assumption to make as the bootloader must configure and access the flash window, the output display (LCD, LEDs, etc) window, and other expansion bus devices.
