Reformat the Atari SCSI driver Signed-off-by:

Michael Schmitz authored
SCSI should be working on a TT (but someone should really try!) but causes trouble on a Falcon (as in: it ate a filesystem of mine) at least when used concurrently with IDE. I have the notion it's because locking of the ST-DMA interrupt by IDE is broken in 2.6 (the IDE driver always complains about trying to release an already-released ST-DMA). Needs more work, but that's on the IDE or m68k interrupt side rather than SCSI. Signed-off-by:

Cornelia Huck authored
These helper functions are a leftover from 2.4 sync I/O and are a notorious source for bugs. They lead to device driver specific code creeping into cio, and some issues can't really be fixed at all. Device drivers can easily implement those functions themselves in a more robust manner, so let's get rid of them. Signed-off-by:

Commit c1821c2e introduced the uaccess structure that is used to select the correct set of user copy functions for the different execution modes (standard vs. noexec vs. z9 optimized user copy). The uaccess symbol is exported with EXPORT_SYMBOL_GPL. This breaks all non-gpl modules that use user copy. To make them work again change the export to EXPORT_SYMBOL. Signed-off-by:

When compiled as a module, the i2c-s3c2410 driver does not free either the IRQ or the i2c adapter it attached to the system. As part of this fix, move to the usual kernel style of freeing items as part of the probe error path making the remove process easier. Signed-off-by:

Make the documentation on how to write and port i2c drivers more in line with the current state of things: * i2c-isa is deprecated and soon gone, so stop advertising it. * Drop many sensors-specific references. Most of them were outdated anyway. * Update the example code to reflect the recent and not-so-recent API and coding style preference changes. * Simplify the example init and cleanup functions. This should make things less complex to understand for newcomers. Signed-off-by: -

Haavard Skinnemoen authored
This is a very simple bitbanging I2C bus driver utilizing the new arch-neutral GPIO API. Useful for chips that don't have a built-in I2C controller, additional I2C busses, or testing purposes. To use, include something similar to the following in the board-specific setup code: #include <linux/i2c-gpio.h> static struct i2c_gpio_platform_data i2c_gpio_data = { .sda_pin = GPIO_PIN_FOO, .scl_pin = GPIO_PIN_BAR, }; static struct platform_device i2c_gpio_device = { .name = "i2c-gpio", .id = 0, .dev = { .platform_data = &i2c_gpio_data, }, }; Register this platform_device, set up the I2C pins as GPIO if required and you're ready to go. This will use default values for udelay and timeout, and will work with GPIO hardware that does not support open drain mode, but allows sensing of the SDA and SCL lines even when they are being driven.

It was reported to me that the i2c-pxa driver was not able to process more that 50 transactions per second. Investigation revealed that the I2C unit was busy for 20 ms after every transaction. The reason seems to be that we forget to clear the STOP and ACKNACK bits at the end of the transaction. According to the PXA27x developer's manual, we shall do so. Signed-off-by: -

Improve the debugging features of the i2c-algo-bit driver: * Make it possible to compile the driver without debugging support at all, making it much smaller. * Use dev_dbg() for debugging messages where possible, and dev_err() for error messages. * Remove redundant debugging messages. These changes allowed for minor code cleanups, which are included as well. Signed-off-by: -

The original i2c-algo-bit implementation uses a 33/66 SCL duty cycle when bits are being written on the bus. While the I2C specification doesn't forbid it, this prevents us from driving the I2C bus to its max speed, limiting us to 66 kbps max on standard I2C busses. Implementing a 50/50 duty cycle instead lets us max out the bandwidth up to the theoretical max of 100 kbps on standard I2C busses. This is particularly important when large amounts of data need to be transfered over the bus, as is the case with some TV adapters when the firmware is being uploaded. In fact this change even allows, at least in theory, fast-mode I2C support at 125, 166 and 250 kbps. There's no way to reach the theoretical max of 400 kbps with this implementation. But I don't think we want to put efforts in that direction anyway: software-driven I2C is very CPU-intensive and bad for latency. Other timing changes: * Don't set SDA high explicitly on error, we're going to issue a stop condition before we leave anyway. * If an error occurs when sending the slave address, yield the CPU before retrying, and remove the additional delay after the new start condition.
