From: Candelaria Villareal, Jorge Date: Tue, 25 Aug 2009 15:13:25 +0000 (-0500) Subject: ASoC: SDP3430: Fix TWL GPIO6 pin mux request X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=30cd0c4ad57f45e257758edad537cc5f6554e711;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ASoC: SDP3430: Fix TWL GPIO6 pin mux request Fix the write to PMBR1 register through I2C. Also, the constant which holds the value to write is now called TWL4030_GPIO6_PWM0_MUTE. This name is based on TRM to avoid confusion.
