spi: imx/fsl-lpspi: Convert to GPIO descriptors This converts the two Freescale i.MX SPI drivers Freescale i.MX (CONFIG_SPI_IMX) and Freescale i.MX LPSPI (CONFIG_SPI_FSL_LPSPI) to use GPIO descriptors handled in the SPI core for GPIO chip selects whether defined in the device tree or a board file. The reason why both are converted at the same time is that they were both using the same platform data and platform device population helpers when using board files intertwining the code so this gives a cleaner cut. The platform device creation was passing a platform data container from each boardfile down to the driver using struct spi_imx_master from <linux/platform_data/spi-imx.h>, but this was only conveying the number of chipselects and an int * array of the chipselect GPIO numbers. The imx27 and imx31 platforms had code passing the now-unused platform data when creating the platform devices, this has been repurposed to pass around GPIO descriptor tables. The platform data struct that was just passing an array of integers and number of chip selects for the GPIO lines has been removed. The number of chipselects used to be passed from the board file, because this number also limits the number of native chipselects that the platform can use. To deal with this we just augment the i.MX (CONFIG_SPI_IMX) driver to support 3 chipselects if the platform does not define "num-cs" as a device property (such as from the device tree). This covers all the legacy boards as these use <= 3 native chip selects (or GPIO lines, and in that case the number of chip selects is determined by the core from the number of available GPIO lines). Any new boards should use device tree, so this is a reasonable simplification to cover all old boards. The LPSPI driver never assigned the number of chipselects and thus always fall back to the core default of 1 chip select if no GPIOs are defined in the device tree. The Freescale i.MX driver was already partly utilizing the SPI core to obtain the GPIO numbers from the device tree, so this completes the transtion to let the core handle all of it. All board files and the core i.MX boardfile registration code is augmented to account for these changes. This has been compile-tested with the imx_v4_v5_defconfig and the imx_v6_v7_defconfig.
