Thank you all for providing inputs and comments on previous versions of this patchset. Especially thanks to the (Doug, Rob....).
We need the OTP pin is gpio state before resetting the TSADC controller, since the tshut polarity will generate a high signal. Says: The TSHUT temperature is setting more than 80 degree, the default tshut polarity is HIGH. If T > 80C, the OTP output the High Signal. If T < 80C, the OTP output the Low Signal. On the moment, the TSADC controller is reset, the tshut polarity will be Low in a short period of time. So: If T < 80C, the OTP output the High Signal. If T > 80C, the OTP output the Low Signal. In some cases, the OTP pin is connected to the PMIC, maybe the PMIC can accept the reset response time to avoid this issue. In other words, the system will be always reboot if we make the OTP pin is connected the others IC to control the power. This series patchs are depend on Doug's patch.(https://patchwork.kernel.org/patch/7454311/) This series patchs are based on the Linus master branch. 518cd44 ARM: dts: rockchip: Add the OTP gpio pinctrl 83e0bab dt-bindings: Add the "init" pinctrl in this document 150426c drivers/pinctrl: Add the concept of an "init" state ce1fad2 Merge branch 'keys-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs 1099f86 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net 911b79c KEYS: Don't permit request_key() to construct a new keyring 37850e3 net: bcmgenet: Fix early link interrupt enabling afc050d Merge tag 'wireless-drivers-for-davem-2015-10-17' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers e277de5 tunnels: Don't require remote endpoint or ID during creation. 740dbc2 openvswitch: Scrub skb between namespaces .... Tested on box board. Changes in v3: - Add the pictrl states decription in document. - Add the pinctrl state for in the suspend/resume. - Add the "sleep" pinctrl as the gpio state in PATCH[3/3] Changes in v2: - Add the 'init' pinctrl more decription in commit. - Fix the subject to make more obvious in PATCH[1/2] - Resend this patch v2 since fix the subject to be specific. - Add some commits for more obvious in PATCH[2/2] Changes in v1: - As the Doug comments, add the 'init' property to sync document. - As the Doug comments, drop the thermal driver patchs since we can with pinctrl changing to work. - As the Doug's patch to add the 'init' property.
