• e7db06b5d   spi: move more spi_setup() functionality into core ... Browse Code »

  Move some common spi_setup() error checks into the SPI framework from the
  spi_master controller drivers:

  - Add a new "mode_bits" field to spi_master

  - Use that in spi_setup to validate the spi->mode value being
  requested. Setting this new field is now mandatory for any
  controller supporting more than vanilla SPI_MODE_0.

  - Update all spi_master drivers to:

  * Initialize that field
  * Remove current spi_setup() checks using that value.

  This is a net minor code shrink.

• 7d0771970   spi: move common spi_setup() functionality into core ... Browse Code »

  Start moving some spi_setup() functionality into the SPI core from the
  various spi_master controller drivers:

  - Make that function stop being an inline;

  - Move two common idioms from drivers into that new function:
  * Default bits_per_word to 8 if that field isn't set
  * Issue a standardized dev_dbg() message

  This is a net minor source code shrink, and supports enhancments found in
  some follow-up patches.

• 60cadec9d   spi: new orion_spi driver ... Browse Code »

  This adds an SPI driver for the SPI controller found in various Marvell
  Orion ARM SoCs. It currently supports only one slave, which must use SPI
  mode 0.
