* i2c: Add driver suspend/resume/shutdown supportDavid Brownell2007-02-13
| | | | | | | | | | | | | | | | | | Driver model updates for the I2C core: - Add new suspend(), resume(), and shutdown() methods. Use them in the standard driver model style; document them. - Minor doc updates to highlight zero-initialized fields in drivers, and the driver model accessors for "clientdata". If any i2c drivers were previously using the old suspend/resume calls in "struct driver", they were getting warning messages ... and will now no longer work. Other than that, this patch changes no behaviors; and it lets I2C drivers use conventional PM and shutdown support.

* i2c-ali1563: Fix device initializationJean Delvare2007-02-13
| | | | | | | | | | | | | | | | | | The i2c-ali1563 initialization looks quite broken to me: * If the I/O space isn't enabled, we forcibly set 3 bits in the PCI configuration space instead of just the one enabling the I/O space. * After that we pretend to check if the write worked, but we don't actually read the new value from the register. * It's probably not a good idea to enable the I/O space if no base address has been set. So I propose the following changes to that part of the driver: * Merge ali1563_enable() into ali1563_setup(). * Check the base address before the I/O space enabled bit.

| * [SPARC]: Re-export saved_command_line to modules.David S. Miller2007-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | This reverts some bogosity from the dynamic command-line changes made on sparc32 and sparc64. Drivers such as drivers/sbus/char/openprom.c reference saved_command_line, and can be modular. The boot_command_line is __initdata, yet the dynamic command-line changes add modular exports of that symbol, obviously wrong. Signed-off-by: David S. Miller <davem@davemloft.net>

In order to fix this up, introduce the following interface changes: ccw_device_set_options() now only sets the specified bits, but does not clear those that are not specified. ccw_device_clear_options() clears the specified bits. ccw_device_set_options_mask() provides the old semantics (setting only the specified bits and clearing the others).
