Subject: [PATCH] spi: spi-fsl-qspi: Introduce variable to fix different
|
|
invalid master Id
|
|
|
|
Different platforms have different Master with different SourceID on
|
|
AHB bus. The 0X0E Master ID is used by cluster 3 in case of LS2088A.
|
|
So, patch introduce an invalid master id variable to fix invalid
|
|
mastered on different platforms.
