* i2c: i2c-mpc: make I2C bus speed configurableWolfgang Grandegger2009-04-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes the I2C bus speed configurable by using the I2C node property "clock-frequency". If the property is not defined, the old fixed clock settings will be used for backward comptibility. The generic I2C clock properties, especially the CPU-specific source clock pre-scaler are defined via the OF match table: static const struct of_device_id mpc_i2c_of_match[] = { ... {.compatible = "fsl,mpc8543-i2c", .data = &(struct fsl_i2c_match_data) { .setclock = mpc_i2c_setclock_8xxx, .prescaler = 2, }, }, The "data" field defines the relevant I2C setclock function and the relevant pre-scaler for the I2C source clock frequency. It uses arch-specific tables and functions to determine resonable Freqency Divider Register (fdr) values for MPC83xx, MPC85xx, MPC86xx, MPC5200 and MPC5200B. The i2c->flags field and the corresponding FSL_I2C_DEV_* definitions have been removed as they are obsolete.

* i2c-s3c2410: Simplify bus frequency calculationDaniel Silverstone2009-04-07
| | | | | | | | | | | | | | | | | The platform data for the i2c-s3c2410 driver used to allow a min, max and desired frequency for the I2C bus. This patch reduces it to simply a desired frequency ceiling and corrects all the uses of the platform data appropriately. This means, for example, that on a system with a 66MHz fclk, a request for 100KHz will achieve 65KHz which is safe and acceptable, rather than 378KHz which it would have achieved without this change.

| | | | | | | | | | | This makes the defautl ext3 data ordering mode (when no explicit ordering is set) configurable, so as to allow people to default to 'data=writeback' and get the resulting latency improvements.

| * UBIFS: fix recovery bugAdrian Hunter2009-03-31
| | | | | | | | | | | | | | | | | | | | | | UBIFS did not recovery in a situation in which it could have. The relevant function assumed there could not be more nodes in an eraseblock after a corrupted node, but in fact the last (NAND) page written might contain anything.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Now UBIFS is supported by u-boot. If we ever decide to change the media format, then people will have to upgrade their u-boots to mount new format images. However, very often it is possible to preserve R/O forward-compatibility, even though the write forward-compatibility is not preserved. This patch introduces a new super-block field which stores the R/O compatibility version.

| * UBIFS: fix bug where page is marked uptodate when out of spaceAdrian Hunter2009-03-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UBIFS fast path in write_begin may mark a page up to date and then discover that there may not be enough space to do the write, and so fall back to a slow path. The slow path tries harder, but may still find no space - leaving the page marked up to date, when it is not. This patch ensures that the page is marked not up to date in that case. The bug that this patch fixes becomes evident when the write is into a hole (sparse file) or is at the end of the file and a subsequent read is off the end of the file. In both cases, the file system should return zeros but was instead returning the page that had not been written because the file system was out of space.

The TQM8548_BE requires a further short delay after writing out a buffer. Normally the R/B pin should be checked, but it's not connected on the TQM8548_BE. The existing driver uses similar fixed delay points. To manage these extra delays in a more general way, I introduced the "fsl,ump-wait-flags" property allowing the board- specific driver to specify various types of extra delay.

MTD drivers should set the dev.parent field to point to the physical device, before setting up partitions or otherwise declaring MTDs. - Those device nodes always map to /sys/class/mtdX device nodes, which no longer depend on MTD_CHARDEV. - Those mtdX sysfs nodes have a "starter set" of attributes; it's not yet sufficient to replace /proc/mtd. - Enabling MTD_CHARDEV provides /sys/class/mtdXro/ nodes and the /sys/class/mtd*/dev attributes (for udev, mdev, etc). - Include a MODULE_ALIAS_CHARDEV_MAJOR macro. It'll work with udev creating the /dev/mtd* nodes, not just a static rootfs. So the sysfs structure is pretty much what you'd expect, except that readonly chardev nodes are a bit quirky.

Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SLOF has a further node which could not be evaluated by the current routine. The current routine returns because the node hasn't the required reg property. As fix this patch adds a check to determine the partition child nodes. If the node is not a partition the number of total partitions will be decreased and loop continues with the next nodes.
