Subject: [PATCH] msm: pinctrl: 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.
|
|
|
|
IPQ40xx SoC:
|
|
2'b10: Internal pull up enable.
|
|
2'b11: Unsupport
|
|
|
|
For other SoC's:
|
|
2'b10: Keeper
|
|
2'b11: Pull-Up
|
