* [PATCH 0/2] pinctrl-single: introduce am654-padconf compatible @ 2023-08-08 10:22 ` Dhruva Gole 0 siblings, 0 replies; 15+ messages in thread From: Dhruva Gole @ 2023-08-08 10:22 UTC (permalink / raw) To: Tony Lindgren, Linus Walleij, Conor Dooley Cc: linux-gpio, devicetree, linux-kernel, linux-arm-kernel, linux-omap, Dhruva Gole, Nishanth Menon, Vignesh Raghavendra, Conor Dooley, Krzysztof Kozlowski, Rob Herring, Haojian Zhuang The K3 family of SOCs use certain bits of the padconfig registers like WKUP_EVT and WKUP_EN to enable daisychain wakeups. For example, these bits are described in the AM654 TRM [0] under "Table 5-517. Description Of The Pad Configuration Register Bits" This series adds the DT binding changes for adding the compatible and also the driver changes which make use of this compatible. NOTE: Some K3 SoCs may have these bits marked as reserved which means that they don't support IO daisychain. Such SOCs are not expected to use this compatible. The general expected usage is when the device is in a suspended state like Deep Sleep or Suspend to RAM, and any IO activity on configured pads can trigger a wakeup.
