[PATCH v3 0/4] Fix for imx-spi CS GPIOs

[Trent Piepho]

This fixes a bug where GPIO based chip selects must be specified in the OF
node for spi-imx when they should be optional.

Fixes a regression in the platform data of imx31moboard.

Clean up of some old platform data based spi-imx users.

Changes from V1:
 * Collected reviewed bys.
 * Minor change to coding style in one patch.

Changes from V2:
 * Reverted minor coding change from V2, it was right to begin with
 * Have imx-spi also honor "num-cs" property
 * Leak of spi_bitbang on failure needed to be fixed differently
 * Port to linux-next, which has other changes to spi-imx

Trent Piepho (4):
  spi: imx: GPIO based chip selects should not be required
  spi: imx: Fix failure path leak on GPIO request error
  spi: imx: Don't require platform data chipselect array
  ARM: imx: Update spi_imx platform data to reflect current state
