I have use case that at some point I need to reconfigure SPI pads to HiZ state.
I'm wondering what is the state of SPI lines after unbinding spi driver in fsl kernel 3.10?
In function spi_imx_remove() I see that
writel(0, spi_imx->base + MXC_CSPICTRL);
May I assume that after unbinding spi driver and having 0 in MXC_CSPICTRL, spi lines for this controller are in HiZ state?
