Subject: [PATCH 0/2] spi: atmel-quadspi: Fix and add full CS delay support
Date: Wed, 18 Sep 2024 10:27:42 +0200 [thread overview]
Message-ID: <20240918082744.379610-1-ada@thorsis.com> (raw)
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.
