[V4] : This patch series version includes - Updated GPIO based chip select control using GPIO descriptor. - HW based chip select implementation is same as V3 but V4 has this patch updated to be on top of above changes. - HW CS timing implementation is same as V3 but V4 has this patch updated to be on top of above changes. - support for TX and RX trimmers implementation is same as V3 but V4 has this patch updated to be on top of above changes and updated commit description. [V3] : This patch series version includes - only patches that are not applied from V2. - splitted expanding mode and adding LSByte First support in separate patches and removed DT property for selecting LSByte First. - Updated GPIO based chip select control to use spi_set_cs from SPI core. - HW based chip select implementation is same as V2 but V3 has this patch updated to be on top of above changes. - HW CS timing implementation is same as V2 but V3 has this patch updated to be on top of above changes. - support for TX and RX trimmers implementation is same as V2 but V3 has this patch updated to be on top of above changes and updated commit description. [V2] : This patch series version includes - only patches that are not applied from V1. - changed order of patches to include all fixes prior to new features support. - Removed HW CS timing from DT properties and created set_cs_timing SPI master optional method for SPI controllers to implement and created API spi_cs_timing for SPI client drivers to request CS setup, hold and inactive delay timing configuration. - Fixed HW based CS decision to be based on single transfer and cs_change. Remove selection of HW based CS through DT.
