[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.
