[MTD] Use mutex instead of semaphore in dataflash driver

2007-06-28T21:58:42+00:00

The MTD DataFlash driver uses a semaphore as mutex.  Use the mutex API instead
of the (binary) semaphore.

[PATCH] SPI/MTD: mtd_dataflash oops prevention

2006-12-30T18:56:42+00:00

Return a fault code if the Dataflash driver runs into a "no device present"
error when the MISO line has a pulldown (it currently expects a pullup), so
that rmmod won't oops.

[PATCH] getting rid of all casts of k[cmz]alloc() calls

2006-12-13T17:05:58+00:00

Run this:

	#!/bin/sh
	for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
	  echo "De-casting $f..."
	  perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
	done

And then go through and reinstate those cases where code is casting pointers
to non-pointers.

And then drop a few hunks which conflicted with outstanding work.

[PATCH] mtd_dataflash, fix block vs page erase

2006-03-14T15:57:17+00:00

Fix a bug in the block-erase optimization for Dataflash; it was using block
erase even for smaller segments that need page erase.

That wouldn't matter for JFFS2, which never erases less than one block
(sometimes several blocks), but for other callers it might.

[PATCH] spi: misc fixes

2006-01-14T00:29:56+00:00

This collects some small SPI patches that seem to be missing from the MM tree:

  - spi_butterfly kbuild hooks got dropped somehow; this restores them
  - quick fix for a (theoretical?) m25p80_write() oops noted by Andrew
  - quick fix for a potential config-specific oops for mtd_dataflash()
  - minor doc tweaks

[PATCH] spi: use linked lists rather than an array

2006-01-14T00:29:56+00:00

This makes the SPI core and its users access transfers in the SPI message
structure as linked list not as an array, as discussed on LKML.

From: David Brownell 

  Updates including doc, bugfixes to the list code, add
  spi_message_add_tail().  Plus, initialize things _before_ grabbing the
  locks in some cases (in case it grows more expensive).  This also merges
  some bitbang updates of mine that didn't yet make it into the mm tree.
