Subject[PATCH 5.3 273/344] spi: ep93xx: Repair SPI CS lookup tables
Date
From: Alexander Sverdlin <alexander.sverdlin@gmail.com>

commit 4fbc485324d2975c54201091dfad0a7dd4902324 upstream.

The actual device name of the SPI controller being registered on EP93xx is
"spi0" (as seen by gpiod_find_lookup_table()). This patch fixes all
relevant lookup tables and the following failure (seen on EDB9302):

ep93xx-spi ep93xx-spi.0: failed to register SPI master
ep93xx-spi: probe of ep93xx-spi.0 failed with error -22

Fixes: 1dfbf334f1236 ("spi: ep93xx: Convert to use CS GPIO descriptors")
