2009-12-17spi_s3c24xx: add FIQ pseudo-DMA supportBen Dooks1-13/+231
Add pseudo-DMA by FIQ to the S3C24XX SPI driver. This allows the driver to get DMA-like performance where there are either no free DMA channels or when doing transfers that required both TX and RX data paths. Since this patch requires the addition of an assembly file to hold the FIQ code, we rename the module (instead of adding a rename of the .c file to this patch). We expect most users are loading this via udev and thus there should be no change to the userland configuration.

2009-09-23spi_s3c24xx: cache device setup dataBen Dooks1-37/+89
With the update to the spi_bitbang driver, the transfer setup code is being called more often, and thus is often re-doing calculations that have been done before. The SPI layer allows our driver to add its own data to each device so add a result cache to each device. This should also remove the problem where we where directly setting up registers in the setup call which meant we might overwrite the state of an extant transfer., Signed-off-by: Ben Dooks <ben@simtec.co.uk> Cc: David Brownell <david-b@pacbell.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

The two S3C SPI master drivers got merged without much review, so I just noticed that they're doing something that the SPI core code is responsible for, rather than any adapter driver: they try to register SPI devices. This removes that support from those drivers so they act normally. Interestingly, none of the current boards are affected. So it's a net code shrink with no loss of functionality.

2007-10-16SPI driver runtime footprint shrinkageDavid Brownell1-5/+4
Shrink the runtime footprint of various SPI drivers: - Move the probe() routine into the init section where practical, using platform_driver_probe() to make that safe. This often saves around 1KB. Using platform_driver_probe() can also be a correctness fix, if the probe routine is already marked __init but the driver struct keeps a dangling pointer to it after init section removal. - Likewise move remove() routines into the exit sections. These changes would be inappropriate iff the platform devices were actually hotpluggable (e.g. they're found on optional addon cards, or in an FPGA that's dynamically reprogrammed). In these cases, that's not the situation; it's an SOC controller and the only device is initialized before these drivers.

2007-08-31SPI driver hotplug/coldplug fixesDavid Brownell1-0/+1
Update various SPI drivers so they properly support - coldplug through "modprobe $(cat /sys/devices/.../modalias)" - hotplug through "modprobe $(MODALIAS)" The basic rule for platform, SPI, and (new style) I2C drivers is just to make sure that modprobing the driver name works. In this case, all the relevant drivers are platform drivers, and this patch either (a) Changes the driver name, if no in-tree code would break; this is simpler and thus preferable in the long term. (b) Adds MODULE_ALIAS directives, when in-tree platforms declare devices using the current driver name; less desirable. Most systems will link SPI controller drivers statically, but there's no point in being needlessly broken.

2006-12-30[PATCH] SPI: define null tx_buf to mean "shift out zeroes"David Brownell1-1/+1
Some issues were recently turned up with the current specification of what it means for spi_transfer.tx_buf to be null, as part of transfers which are (from the SPI protocol driver perspective) pure reads. Specifically, that it seems better to change the TX behaviour there from "undefined" to "will shift zeroes". This lets protocol drivers (like the ads7846 driver) depend on that behavior. It's what most controller drivers in the tree are already doing (with one exception and one case of driver wanting-to-oops), it's what Microwire hardware will necessarily be doing, and it removes an issue whereby certain security audits would need to define such a value anyway as part of removing covert channels. This patch changes the specification to require shifting zeroes, and updates all currently merged SPI controller drivers to do so.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells1-1/+1
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.
