[Cause of problem] Logic of NFC HAL: after sending the commands, HAL will pull down NFC GPIO0 and notify NFC chip that it can sleep after wait for 1 second. If power key is pressed, AP will sleeps quickly, so that the 1 second timeout processing of NFC HAL can not be executed, so the NFC chip cannot sleep. But there is no issue if enter sleep is by screen auto time-out [Solution] In the NFc driver suspend call, check whether the hal has pulled down NFC GPIO0. If not, prevent the system go to sleep 1 second. [Side-effect] None (The time to prevent go to sleep is 1 second, this can be ignored in power consumption) Change-Id: If344d4510b02fef66bb23bfe05942c20280b9e02 Reviewed-on: https://gerrit.mot.com/2229464 SME-Granted: SME Approvals Granted SLTApproved: Slta Waiver Tested-by: Jira Key Reviewed-by: Wang Wang <wangwang1@lenovo.com> Reviewed-by: Zhenghai Pan <panzh2@lenovo.com> Reviewed-by: <tinno18@motorola.com> Submit-Approved: Jira Key
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
