[PATCH linux dev-4.17 v2 0/2] mtd: spi-nor: aspeed: introduce a "spi-max-frequency" property

[Cédric Le Goater]

Hello,

The "spi-max-frequency" property protects the driver from some
optimistic settings of the optimize read algo for certain chips (old
ones). It also makes the read access to the alternate FMC chip 3 times
faster.

Thanks,

C.

Changes since v1:

 - moved to the dev-4.17 branch
 - introduced the optimize read algo on the AST2400 SoC FMC controller.
