platform: tegra: add support for pm debugfs nodes 2018-03-09T12:30:50+00:00 Vignesh Radhakrishnan vigneshr@nvidia.com 2017-04-12T20:23:27+00:00 216d6a5c9a914d1841e71a18d8b901e4d99feea7 Add support for creating debugfs nodes that is used by Tegra PM framework. This patch does the following: 1. Create debugfs directory /d/system_states 2. Support a common interface for requesting the debugfs handle of /d/system_states a. This is to ensure functions across multiple files can add nodes to this debugfs node 3. Add debugfs node /d/system_states/suspend_debug_flags to support entry inside fake system suspend mode. a. Writing to this node communicates with ATF using an SMC call to enter fake system suspend mode. b. This debug mode requests for a warm reset of CPU instead of WFI, thus bypassing underneath layers during system suspend c. This debug mode is primarily used for circumventing limitations in pre-silicon platforms JIRA TPM-1204 Change-Id: I456c9f0059abf0df0e5325e21c06e2c2a59a89c7 Signed-off-by: Vignesh Radhakrishnan <vigneshr@nvidia.com> Reviewed-on: http://git-master/r/1457336 (cherry picked from commit 3d125c0cbc2bb7eeec849ca782ee3fc71cca4907) Signed-off-by: Timo Alho <talho@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1671092 GVS: Gerrit_Virtual_Submit Tested-by: Bitan Biswas <bbiswas@nvidia.com> Reviewed-by: Bitan Biswas <bbiswas@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com> 
Add support for creating debugfs nodes that is
used by Tegra PM framework.

This patch does the following:

1. Create debugfs directory /d/system_states

2. Support a common interface for requesting the debugfs
   handle of /d/system_states
   a. This is to ensure functions across multiple files
      can add nodes to this debugfs node

3. Add debugfs node /d/system_states/suspend_debug_flags
   to support entry inside fake system suspend mode.
   a. Writing to this node communicates with ATF
      using an SMC call to enter fake system suspend
      mode.
   b. This debug mode requests for a warm reset of CPU
      instead of WFI, thus bypassing underneath layers
      during system suspend
   c. This debug mode is primarily used for circumventing
      limitations in pre-silicon platforms
