My tree was in a slightly different state, so it was easier for me
to manually create the new branch, and then merge the standard kernel
BSP into it.
That included the patch you sent earlier, and I've cherry picked the
other from your github branch.

The baseline configuration looks sane to me (I checked for obvious errors and non hardware configs). So I've gone ahead and merged this to the 5.2 and master branches.

[linux-yocto] [kernel v5.2/standard/xlnx-soc][PATCH 2/2] spi: spi-mem: zynq-qspi: add is-dual support for zc706 board
From: Quanyang Wang
There are 2 SPI flash memories in zc706 board and it use the
configuration "Dual SS, 8-bit Parallel" which means separate
Slave-Select lines and separate 4 data lines. So add the is-dual
support for zc706 board according to the spi driver in SDK.
Refer to bd2c1810ae87 ("spi: zynq-qspi: Add driver for zynq qspi")
in https://github.com/Xilinx/linux-xlnx.git xlnx_rebase_v4.19
