Subject: [PATCH 0/2] spi: atmel-quadspi: Fix and add full CS delay support

Hello everyone,

when testing on a SAM9X60 based board with an FPGA implementing a custom
SPI-MEM protocol, we found the need to fully control the delay settings
the atmel/microchip QSPI controller offers.

(series based on v6.11, tested on top of v6.6.44)
