[PATCH 0/2] Add RZ/G2L POEG support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The output pins of the general PWM timer (GPT) can be disabled by using the port
output enabling function for the GPT (POEG). Specifically, either of the
following ways can be used.

  * Input level detection of the GTETRGA to GTETRGD pins.
  * Output-disable request from the GPT.
  * Register settings.

This patch series add support for controlling output disable function using sysfs.

For output disable operation, POEG group needs to be linked with GPT.
Plan to send a follow up patch with renesas,poeg-group as numeric
property in pwm bindings for linking both GPT and POEG devices.


REF->v1:
 * Modelled as pincontrol as most of its configuration is intended to be
   static and moved driver files from soc to pincontrol directory.
 * Updated reg size in dt binding example.
 * Updated Kconfig
