Subject: [PATCH 1/4] arm64: dts: qcom: sdm845: fix number of pins in 'gpio-ranges'
Date: Wed, 3 Mar 2021 11:31:03 +0800 [thread overview]
Message-ID: <20210303033106.549-2-shawn.guo@linaro.org> (raw)
In-Reply-To: <20210303033106.549-1-shawn.guo@linaro.org>
The last cell of 'gpio-ranges' should be number of GPIO pins, and in
case of qcom platform it should match msm_pinctrl_soc_data.ngpio rather
than msm_pinctrl_soc_data.ngpio - 1.
This fixes the problem that when the last GPIO pin in the range is
configured with the following call sequence, it always fails with
-EPROBE_DEFER.
pinctrl_gpio_set_config()
pinctrl_get_device_gpio_range()
pinctrl_match_gpio_range()
Fixes: bc2c806293c6 ("arm64: dts: qcom: sdm845: Add gpio-ranges to TLMM node")
