From: Abdel Alkuor <abdelalkuor@xxxxxxxxxx> Allow controller to enter sleep mode after the device is idle for sleep time. Signed-off-by: Abdel Alkuor <abdelalkuor@xxxxxxxxxx> --- Changes in v6: - Use tps25750_init instead of tps25750_apply_patch in resume as it initializes sleep mode Changes in v5: - Incorporating tps25750 into tps6598x driver drivers/usb/typec/tipd/core.c | 23 +++++++++++++++++++++-- drivers/usb/typec/tipd/tps6598x.h | 3 +++ 2 files changed, 24 insertions(+), 2 deletions(-) diff --git a/drivers/usb/typec/tipd/core.c b/drivers/usb/typec/tipd/core.c index cfaad9a917a2..b9bb3d462742 100644 --- a/drivers/usb/typec/tipd/core.c +++ b/drivers/usb/typec/tipd/core.c @@ -42,6 +42,7 @@ #define TPS_REG_PD_STATUS 0x40 #define TPS_REG_RX_IDENTITY_SOP 0x48 #define TPS_REG_DATA_STATUS 0x5f +#define TPS_REG_SLEEP_CONF 0x70 /* TPS_REG_SYSTEM_CONF bits */ #define TPS_SYSCONF_PORTINFO(c) ((c) & 7) @@ -1006,6 +1007,24 @@ static int tps25750_apply_patch(struct tps6598x *tps) return 0; }; +static int tps25750_init(struct tps6598x *tps) +{ + int ret; + + ret = tps25750_apply_patch(tps); + if (ret) + return ret; + + ret = tps6598x_write8(tps, TPS_REG_SLEEP_CONF, + TPS_SLEEP_CONF_SLEEP_MODE_ALLOWED); + if (ret) + dev_warn(tps->dev, + "%s: failed to enable sleep mode: %d\n", + __func__, ret); + + return 0; +} + static int tps6598x_register_port(struct tps6598x *tps, struct fwnode_handle *fwnode) { @@ -1196,7 +1215,7 @@ static int tps6598x_probe(struct i2c_client *client) return ret; if (is_tps25750 && ret == TPS_MODE_PTCH) { - ret = tps25750_apply_patch(tps); + ret = tps25750_init(tps); if (ret) return ret; } @@ -1335,7 +1354,7 @@ static int __maybe_unused tps6598x_resume(struct device *dev) return ret; if (of_device_is_compatible(np, "ti,tps25750") && ret == TPS_MODE_PTCH) { - ret = tps25750_apply_patch(tps); + ret = tps25750_init(tps); if (ret) return ret; } diff --git a/drivers/usb/typec/tipd/tps6598x.h b/drivers/usb/typec/tipd/tps6598x.h index 3a9a43394134..f86b5e96efba 100644 --- a/drivers/usb/typec/tipd/tps6598x.h +++ b/drivers/usb/typec/tipd/tps6598x.h @@ -213,4 +213,7 @@ #define TPS_PD_STATUS_PORT_TYPE_SOURCE 2 #define TPS_PD_STATUS_PORT_TYPE_SOURCE_SINK 3 +/* SLEEP CONF REG */ +#define TPS_SLEEP_CONF_SLEEP_MODE_ALLOWED BIT(0) + #endif /* __TPS6598X_H__ */ -- 2.34.1
