From de705fa1f470683b9ea4ad91c1a9ae5a98942612 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Wed, 19 Apr 2017 19:27:28 -0700 Subject: drivers/spi: Re-factor spi_crop_chunk spi_crop_chunk is a property of the SPI controller since it depends upon the maximum transfer size that is supported by the controller. Also, it is possible to implement this within spi-generic layer by obtaining following parameters from the controller: 1. max_xfer_size: Maximum transfer size supported by the controller (Size of 0 indicates invalid size, and unlimited transfer size is indicated by UINT32_MAX.) 2. deduct_cmd_len: Whether cmd_len needs to be deducted from the max_xfer_size to determine max data size that can be transferred. (This is used by the amd boards.)
