Subject: [PATCH V1 2/2] pinctrl: qcom: spmi-gpio: Set is_enabled flag in set_mux()
Date: Fri, 13 Oct 2017 14:15:04 +0800 [thread overview]
Message-ID: <20171013061550.996-3-fenglinw@codeaurora.org> (raw)
In-Reply-To: <20171013061550.996-1-fenglinw@codeaurora.org>
From: Fenglin Wu <fenglinw@codeaurora.org>
The initial value of is_enabled flag is read out from hardware in
pmic_gpio_populate(), and it will be set in pmic_gpio_config_set() if
pinconf is defined. For any GPIOs disabled initially in hardware which
only have pinmux defined, they won't be enabled in pmic_gpio_set_mux()
calling. So set is_enabled flag in set_mux() to ensure the GPIO module
could be enabled in above case.
