Subject: memory: omap-gpmc: Fix omap gpmc EXTRADELAY timing
From: Ocquidant, Sebastien <sebastienocquidant@xxxxxxxxx>
commit 8f50b8e57442d28e41bb736c173d8a2490549a82 upstream.
In the omap gpmc driver it can be noticed that GPMC_CONFIG4_OEEXTRADELAY
is overwritten by the WEEXTRADELAY value from the device tree and
GPMC_CONFIG4_WEEXTRADELAY is not updated by the value from the device
tree.
As a consequence, the memory accesses cannot be configured properly when
the extra delay are needed for OE and WE.
Fix the update of GPMC_CONFIG4_WEEXTRADELAY with the value from the
device tree file and prevents GPMC_CONFIG4_OEXTRADELAY
being overwritten by the WEXTRADELAY value from the device tree.
