Subject: ARM: OMAP2+: Convert TUSB to use gpmc_cs_program_settings()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=012e338625f5ea58d2a16cf98a44779255b458ca;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ARM: OMAP2+: Convert TUSB to use gpmc_cs_program_settings()

Convert the OMAP2+ TUSB code to use the gpmc_cs_program_settings()
function for configuring the various GPMC options instead of directly
programming the CONFIG1 register.
