2009-05-29mtd: Fix handling of mtdname in txx9ndfmc.cDavid Woodhouse
As pointed out by Kay Sievers, the name size limit is gone from the driver-core, and BUS_ID_SIZE is obsolescent. Rather than just papering over the problem by replacing the mtdname array size with an arbitrary '20 + 2', fix the problem properly and handle arbitrary name sizes.

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.

2009-04-03[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. 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.

"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>

This is a device driver for the NAND flash controller found on the various DaVinci family chips. It handles up to four SoC chipselects, and some flavors of secondary chipselect (e.g. based on upper bits of the address bus) as used with some multichip packages. (Including the 2 GiB chips used on some TI devel boards.) The 1-bit ECC hardware is supported (3 bytes ECC per 512 bytes data); but not yet the newer 4-bit ECC (10 bytes ECC per 512 bytes data), as available on chips like the DM355 or OMAP-L137 and needed with the more error-prone MLC NAND chips.

2009-03-20[MTD] [NAND] fix "raw" reads with ECC syndrome layoutsDavid Brownell
The syndrome based page read/write routines store ECC, and possibly other "OOB" data, right after each chunk of ECC'd data. With ECC chunk size of 512 bytes and a large page (2KiB) NAND, the layout is: data-0 OOB-0 data-1 OOB-1 data-2 OOB-2 data-3 OOB-3 OOB-leftover Where OOBx is (prepad, ECC, postpad). However, the current "raw" routines use a traditional layout -- data OOB, disregarding the prepad and postpad values -- so when they're used with that type of ECC hardware, those calls mix up the data and OOB. Which means, in particular, that bad block tables won't be found on startup, with data corruption and related chaos ensuing. The current syndrome-based drivers in mainline all seem to use one chunk per page; presumably they haven't noticed such bugs. Fix this, by adding read/write page_raw_syndrome() routines as siblings of the existing non-raw routines; "raw" just means to bypass the ECC computations, not change data and OOB layout.

Reads from non-page-aligned addresses were broken because while the address to read from was correctly written to NDCB*, a full page was always read. Fix this by ignoring the column and only using the page address. I suspect this whole-page behavior is due to the controller's need to read the entire page in order to generate correct ECC. In the non-ECC case this could be optimized to use the column address, and to set the read length to what is being requested rather than the length of an entire page.

2009-01-05[MTD] [NAND] alauda: use USB API functions rather than constantsJulia Lawall
This set of patches introduces calls to the following set of functions: usb_endpoint_dir_in(epd) usb_endpoint_dir_out(epd) usb_endpoint_is_bulk_in(epd) usb_endpoint_is_bulk_out(epd) usb_endpoint_is_int_in(epd) usb_endpoint_is_int_out(epd) usb_endpoint_num(epd) usb_endpoint_type(epd) usb_endpoint_xfer_bulk(epd) usb_endpoint_xfer_control(epd) usb_endpoint_xfer_int(epd) usb_endpoint_xfer_isoc(epd) In some cases, introducing one of these functions is not possible, and it just replaces an explicit integer value by one of the following constants: USB_ENDPOINT_XFER_BULK USB_ENDPOINT_XFER_CONTROL USB_ENDPOINT_XFER_INT USB_ENDPOINT_XFER_ISOC An extract of the semantic patch that makes these changes is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r1@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\)) == - \(USB_ENDPOINT_XFER_CONTROL\|0\)) + usb_endpoint_xfer_control(epd) @r5@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bEndpointAddress & \(USB_ENDPOINT_DIR_MASK\|0x80\)) == - \(USB_DIR_IN\|0x80\)) + usb_endpoint_dir_in(epd) @inc@ @@ #include <linux/usb.h> @depends on !inc && (r1||r5)@ @@ + #include <linux/usb.h> #include <linux/usb/...> // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
