commit 181739822cf6f8f4e12b173913af2967a28906c0 upstream.
With the arrival of
commit 2fee9583198eb9 ("spi: dt-bindings: clarify CS behavior for spi-cs-high
and gpio descriptors")
it was clarified what the proper state for cs-gpios should be, even if the
flag is ignored. The driver code is doing the right thing since
766c6b63aa04 ("spi: fix client driver breakages when using GPIO descriptors")
The chip-select of the td028ttec1 panel is active-low, so we must omit
spi-cs-high;
attribute (already removed by separate patch) and should now use
GPIO_ACTIVE_LOW for
the client device description to be fully consistent.
Fixes: 766c6b63aa04 ("spi: fix client driver breakages when using GPIO
descriptors")
