This patchset adds support for the MSPI controller on Cygnus. The existing MSPI driver in the kernel was written for BCMA which is a Broadcom AMBA bus variant used on certain chips such as the 53xx. This patch makes BCMA support optional. The current config is being renamed to make it chip nonspecific supporting BCMA, and a new config is added to support non-BCMA chips. DT support is now mandatory to allow removal of a hardcoded SPI device. Support is also added to set the baud rate. The controller currently runs at the slowest speed possible. Changes from v1: - Split previous patch 2 into two patches to make it easier to review. One commit for the file rename, and one for the actual changes to rename variables, functions, etc. - Checked return value of clk_get_rate(). - ifdef indentation fix.
