From: Ram Chandra Jangir Date: Wed, 24 May 2017 23:30:59 +0000 (+0530) Subject: ipq806x: Add support to configure ipq40xx GPIO_PULL bits X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=d227bb06dfdd027d97e3f430422b42a7927411dd;p=librecmc%2Flibrecmc.git ipq806x: Add support to configure ipq40xx GPIO_PULL bits GPIO_PULL bits configurations in TLMM_GPIO_CFG register differs for IPQ40xx from rest of the other qcom SoC's. This change add support to configure the msm_gpio_pull bits for ipq40xx, It is required to fix the proper configurations of gpio-pull bits for nand pins mux.
