From: Ocquidant, Sebastien Date: Wed, 15 Jun 2016 11:47:35 +0000 (+0200) Subject: memory: omap-gpmc: Fix omap gpmc EXTRADELAY timing X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8f50b8e57442d28e41bb736c173d8a2490549a82;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git memory: omap-gpmc: Fix omap gpmc EXTRADELAY timing 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.
