| 2016-11-25 | spi: imx: use prepare_transfer_hardware() for lpspi | Gao Pan | |
| The old driver enable clk in fsl_lpspi_prepare_message() and disable clk in fsl_lpspi_unprepare_message(). Rather than doing this per message it's a bit better to do it in prepare_transfer_hardware(), that way if there's a sequence of messages queued one after another we don't turn the clock on and off all the time.

| 2016-11-22 | spi: imx: add lpspi bus driver | Gao Pan | |
| This patch adds lpspi driver to support new i.MX products which use lpspi instead of ecspi. The lpspi can continue operating in stop mode when an appropriate clock is available. It is also designed for low CPU overhead with DMA offloading of FIFO register accesses.
