Subject: [PATCH v6 2/9] arm64: dts: Reflect change of FSL QSPI driver and remove unused properties
Date: Tue, 27 Nov 2018 10:24:21 +0000	[thread overview]
Message-ID: <1543314174-28580-3-git-send-email-frieder.schrempf@kontron.de> (raw)
In-Reply-To: <1543314174-28580-1-git-send-email-frieder.schrempf@kontron.de>

The FSL QSPI driver will be moved to the SPI framework and it then
acts as a SPI controller. Therefore the subnodes need to set
spi-[rx/tx]-bus-width = <4>, so quad mode is used just as before.

Also the properties 'num-cs' and 'bus-num' were never read by the
driver and can be removed.

The property 'fsl,qspi-has-second-chip' is not needed anymore
and will be removed after the old driver was disabled to avoid
breaking fsl-ls1046a-rdb.dts.
