Eric Benard 71b7d0d90d mtd: mxc_nand: fix 2KiB pagesize NAND on i.MX27
This patch allows i.MX27 to support 2KiB pagesize NAND flash.
We are using a 1.8V NAND flash which datasheet (unfortunately only
available under NDA) says :
Page size: x8: 2,112 bytes (2,048 + 64 bytes).
Without this patch, all sectors are marked as bad eraseblock.

Vladimir Barinov bd3fd62ecc mtd: MXC NAND support for 2KiB page size flashes
- Add support for 2KiB page size flashes
- Fix page address access for large pages
- Detect oob layout at runtime
- handle pagesize_2k variable
- Fix oob16 layout: reserve location 5 of oob area since it's used for bbt

Magnus Lilja b258fd8d04 mtd: mxc_nand: add correct dev_id parameter to free_irq() calls
Make sure to pass the same dev_id data to free_irq() that was
used when calling request_irq(), otherwise we get a warning about
freeing an already free IRQ.

Vladimir Barinov 8541c1180a mtd: MXC NAND driver fixes (v5)
The following patch fixes:
 - re-initialization of host->col_addr which is used as byte index
   between the successive READID flash commands.
 - compile error when CONFIG_PM is enabled
 - pass on the error code from clk_get()
 - return -ENOMEM in case of failed ioremap()
 - pass on the return value of platform_driver_probe() directly
 - remove excessive printk
 - let command line partition table parsing with mxc_nand name.
   The cmd_line parsing is done via <mtd-id> name that differs
   from mxc_nand by default and looks like "NAND 256MiB 1,8V 8-bit"

David Woodhouse ccd93854d4 [MTD] Remove mtd->{suspend,resume} calls from board drivers
Now the MTD core will do this for us, we don't need to hook it up from
the board drivers.

Shame we can't do shutdown from the class too...

David Brownell 87f39f0493 [MTD] support driver model updates
Follow-on patch to the previous driver model patch for the MTD
framework.  This one makes various MTD drivers connect to the
driver model tree, so /sys/devices/virtual/mtd/* nodes are no
longer present ... mostly drivers used on boards I have handy.

Based on a patch from Kay Sievers.

Sascha Hauer e65fb0099f [ARM] MXC: remove _clk suffix from clock names
The context makes it clear already that these are clocks, so there's
no need for such a suffix. This patch only changes the clocks actually
used in the tree. The remaining clocks are renamed in the subsequent
architecture specific patches.
