2010-03-08driver-core: firmware_class: remove base.h header inclusionLuis R. Rodriguez
base.h is used by base drivers for sharing internal structures. Turns out firmware_class does not depend on it at all so remove it.

2010-03-08sysfs: Cache the last sysfs_dirent to improve readdir scalability v2Eric W. Biederman
When sysfs_readdir stops short we now cache the next sysfs_dirent to return to user space in filp->private_data. There is no impact on the rest of sysfs by doing this and in the common case it allows us to pick up exactly where we left off with no seeking. Additionally I drop and regrab the sysfs_mutex around filldir to avoid a page fault abritrarily increasing the hold time on the sysfs_mutex. v2: Returned to using INT_MAX as the EOF condition. seekdir is ambiguous unless all directory entries have a unique f_pos value.

2010-03-08driver-core: Add attribute argument to class_attribute show/storeAndi Kleen
Passing the attribute to the low level IO functions allows all kinds of cleanups, by sharing low level IO code without requiring an own function for every piece of data. Also drivers can extend the attributes with own data fields and use that in the low level function. This makes the class attributes the same as sysdev_class attributes and plain attributes. This will allow further cleanups in drivers. Full tree sweep converting all users. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-03-08sysfs: Add attribute array to sysdev classesAndi Kleen
Add a attribute array that is automatically registered and unregistered to struct sysdev_class. This is similar to what struct class has. A lot of drivers add list of attributes, so it's better to do this easily in the common sysdev layer. This adds a new field to struct sysdev_class.

The problem is that kobject_add_internal() first adds a kobject to the kset and then try to create sysfs directory for it. If the creation fails, it remove the kobject from the kset. get_device_parent() accesses class_dirs kset while only holding class_dirs.list_lock to see whether the cuse class dir exists. But when it exists, it may not have finished initialization yet or may fail and get removed soon. In the above case, the former happened so the second one ends up trying to create subdirectory under NULL sysfs_dirent. Fix it by grabbing a mutex in get_device_parent().

This patch adds support for the Xilinx XPS IIC Bus Interface. The driver uses the dynamic mode, supporting to put several I2C messages in the FIFO to reduce the number of interrupts.

2010-03-07i2c: omap: Add support for 16-bit registersCory Maccarrone
The current i2c-omap driver is set up for 32-bit registers, which corresponds to most OMAP devices. However, OMAP730/850 based devices use a 16-bit register size. This change modifies the driver to perform a runtime CPU type check to determine the register sizes, and uses a bit shift of either 1 or 2 bits to compute the proper register sizes for all registers.

2010-03-07i2c-pnx: fix setting start/stop conditionLuotao Fu
The start/stop condtions are set in different places repetedly in the i2c-pnx driver. Beside in i2c_pnx_start and i2c_pnx_stop the start/stop bit are also set during the transfer of a i2c message in the master_xmit/rcv calls. This is wrong since we can't set the start/stop condition during the transaction of a single message any way. As a matter of fact, the driver will sometimes set both the start and the stop bits at one time. This can be easily reproduced by sending a simple read request like e.g struct i2c_msg msgs[] = { { addr, 0, 1, buf }, { addr, I2C_M_RD, offset, buf } }; While processing the first message the i2c_pnx_master_xmit will set both the start_bit and the stop_bit, which will eventually confuse the slave. Fixed by remove setting start/stop condition from the transmit routines. Signed-off-by: Luotao Fu <l.fu@pengutronix.de> Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2010-03-07i2c/imx: don't add probe function to the driver structUwe Kleine-König
Having a pointer to the probe function is unnecessary when using platform_driver_probe and yields a section mismatch warning after removing the white list entry "*driver" for { .data$, .data.rel$ } -> { .init.* } mismatches in modpost.

2010-03-07mfd: Fix lpc_sch related depends/selects, fix build errorRandy Dunlap
LPC_SCH is selected by GPI_SCH and I2C_ISCH, even when PCI is not enabled, but LPC_SCH depends on PCI, so make GPI_SCH and I2C_ISCH also depend on PCI. Those 2 selects also need to select what LPC_SCH selects, since kconfig does not follow selects.
