2009-04-06[MTD] [NAND] FSL-UPM: Add wait flags to support board/chip specific delaysWolfgang Grandegger
The NAND flash on the TQM8548_BE modules requires a short delay after running the UPM pattern. 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.

2009-04-04[MTD] support driver model updatesDavid Brownell
Follow-on patch to the previous driver model patch for the MTD framework.

Based on a patch from Kay Sievers. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2009-04-04[MTD] driver model updates (part 2)Kevin Cernekee
1) Add more sysfs attributes: flags, size, erasesize, writesize, oobsize, numeraseregions, name 2) Move core_initcall() code into init_mtd(). The original approach does not work if CONFIG_MTD=m . 3) Add device_unregister() in del_mtd_device() so that devices get removed from sysfs as each driver is unloaded.

2009-04-04[MTD] driver model updatesDavid Brownell
Update driver model support in the MTD framework, so it fits better into the current udev-based hotplug framework: - Each mtd_info now has a device node. 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.

2009-04-03[MTD] [NAND] move gen_nand's probe function to .devinit.textUwe Kleine-König
A pointer to plat_nand_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. 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.

simple_set_mnt() is defined as returning 'int' but always returns 0. Callers assume simple_set_mnt() never fails and don't properly cleanup if it were to _ever_ fail. For instance, get_sb_single() and get_sb_nodev() should: up_write(sb->s_unmount); deactivate_super(sb); if simple_set_mnt() fails. Since simple_set_mnt() never fails, would be cleaner if it did not return anything.

"Lots of device drivers register a 'struct device_driver' with the '.bus' member set to '&platform_bus_type'. This is wrong, since the platform_bus functions expect the 'struct device_driver' to be wrapped up in a 'struct platform_driver' which provides some additional callbacks (like suspend_late, resume_early). The effect may be that platform_suspend_late() uses bogus data outside the device_driver struct as a pointer pointer to the device driver's suspend_late() function or other hard to reproduce failures."(Lothar Wassmann) Signed-off-by: Ming Lei <tom.leiming@gmail.com> Acked-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Acked-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2009-03-20[MTD] mtdoops: allow MTD selection by nameAdrian Hunter
MTD's have both an index number and a name. Formerly, the MTD selected for mtdoops was done only by index number. With this patch, a name can be used instead. For example, the kernel command line: console=ttyMTD5 selects MTD 5 for mtdoops. But now this is also possible: console=ttyMTD,log which selects the MTD named "log" for mtdoops. This has the advantage that partitions can be added or removed that would affect the MTD index number but not the name, without having to then change the kernel command line.
