Signed-off-by: Abhishek Pandit-Subedi Reviewed-by: Heikki Krogerus Reviewed-by: Prashant Malani --- Connector status has several unaligned bitfields (16-bit) that result in difficult to maintain macros. It may be better if we simply re-define these structs as u8[] and add bit range macros to access and cast these values. i.e. struct ucsi_connector_status { u8 raw_data[18]; ... \#define UCSI_CONSTAT_CONNECTOR_STATUS FIELD(u16, 15, 0) \#define UCSI_CONSTAT_BCD_PD_VER_OPER_MODE FIELD(u16, 85, 70) } GET_UCSI_FIELD(con->status, UCSI_CONSTAT_CONNECTOR_STATUS); SET_UCSI_FIELD(con->status, UCSI_CONSTAT_CONNECTOR_STATUS, 0); I didn't find a clear example of an existing mechanism to do this. Would love some pointers here if it already exists and some feedback from the maintainer if this is a direction you want to go. drivers/usb/typec/ucsi/ucsi.h | 50 ++++++++++++++++++++++++++++++++--- 1 file changed, 46 insertions(+), 4 deletions(-) diff --git a/drivers/usb/typec/ucsi/ucsi.h b/drivers/usb/typec/ucsi/ucsi.h index bec920fa6b8a..94b373378f63 100644 --- a/drivers/usb/typec/ucsi/ucsi.h +++ b/drivers/usb/typec/ucsi/ucsi.h @@ -3,6 +3,7 @@ #ifndef __DRIVER_USB_TYPEC_UCSI_H #define __DRIVER_USB_TYPEC_UCSI_H +#include #include #include #include @@ -214,9 +215,29 @@ struct ucsi_connector_capability { #define UCSI_CONCAP_OPMODE_USB2 BIT(5) #define UCSI_CONCAP_OPMODE_USB3 BIT(6) #define UCSI_CONCAP_OPMODE_ALT_MODE BIT(7) - u8 flags; + u32 flags; #define UCSI_CONCAP_FLAG_PROVIDER BIT(0) #define UCSI_CONCAP_FLAG_CONSUMER BIT(1) +#define UCSI_CONCAP_FLAG_SWAP_TO_DFP BIT(2) +#define UCSI_CONCAP_FLAG_SWAP_TO_UFP BIT(3) +#define UCSI_CONCAP_FLAG_SWAP_TO_SRC BIT(4) +#define UCSI_CONCAP_FLAG_SWAP_TO_SINK BIT(5) +#define UCSI_CONCAP_FLAG_EX_OP_MODE(_f_) \ + (((_f_) & GENMASK(13, 6)) >> 6) +#define UCSI_CONCAP_EX_OP_MODE_USB4_GEN2 BIT(0) +#define UCSI_CONCAP_EX_OP_MODE_EPR_SRC BIT(1) +#define UCSI_CONCAP_EX_OP_MODE_EPR_SINK BIT(2) +#define UCSI_CONCAP_EX_OP_MODE_USB4_GEN3 BIT(3) +#define UCSI_CONCAP_EX_OP_MODE_USB4_GEN4 BIT(4) +#define UCSI_CONCAP_FLAG_MISC_CAPS(_f_) \ + (((_f_) & GENMASK(17, 14)) >> 14) +#define UCSI_CONCAP_MISC_CAP_FW_UPDATE BIT(0) +#define UCSI_CONCAP_MISC_CAP_SECURITY BIT(1) +#define UCSI_CONCAP_FLAG_REV_CURR_PROT_SUPPORT BIT(18) +#define UCSI_CONCAP_FLAG_PARTNER_PD_MAJOR_REV(_f_) \ + (((_f_) & GENMASK(20, 19)) >> 19) +#define UCSI_CONCAP_FLAG_PARTNER_PD_MAJOR_REV_AS_BCD(_f_) \ + (UCSI_CONCAP_FLAG_PARTNER_PD_MAJOR_REV(_f_) << 8) } __packed; struct ucsi_altmode { @@ -276,15 +297,36 @@ struct ucsi_connector_status { #define UCSI_CONSTAT_PARTNER_TYPE_DEBUG 5 #define UCSI_CONSTAT_PARTNER_TYPE_AUDIO 6 u32 request_data_obj; - u8 pwr_status; -#define UCSI_CONSTAT_BC_STATUS(_p_) ((_p_) & GENMASK(2, 0)) + + u8 pwr_status[3]; +#define UCSI_CONSTAT_BC_STATUS(_p_) ((_p_[0]) & GENMASK(1, 0)) #define UCSI_CONSTAT_BC_NOT_CHARGING 0 #define UCSI_CONSTAT_BC_NOMINAL_CHARGING 1 #define UCSI_CONSTAT_BC_SLOW_CHARGING 2 #define UCSI_CONSTAT_BC_TRICKLE_CHARGING 3 -#define UCSI_CONSTAT_PROVIDER_CAP_LIMIT(_p_) (((_p_) & GENMASK(6, 3)) >> 3) +#define UCSI_CONSTAT_PROVIDER_CAP_LIMIT(_p_) (((_p_[0]) & GENMASK(5, 2)) >> 2) #define UCSI_CONSTAT_CAP_PWR_LOWERED 0 #define UCSI_CONSTAT_CAP_PWR_BUDGET_LIMIT 1 +#define UCSI_CONSTAT_PROVIDER_PD_VERSION_OPER_MODE(_p_) \ + ((get_unaligned_le32(_p_) & GENMASK(21, 6)) >> 6) +#define UCSI_CONSTAT_ORIENTATION(_p_) (((_p_[2]) & GENMASK(6, 6)) >> 6) +#define UCSI_CONSTAT_ORIENTATION_DIRECT 0 +#define UCSI_CONSTAT_ORIENTATION_FLIPPED 1 +#define UCSI_CONSTAT_SINK_PATH_STATUS(_p_) (((_p_[2]) & GENMASK(7, 7)) >> 7) +#define UCSI_CONSTAT_SINK_PATH_DISABLED 0 +#define UCSI_CONSTAT_SINK_PATH_ENABLED 1 + u8 pwr_readings[9]; +#define UCSI_CONSTAT_REV_CURR_PROT_STATUS(_p_) ((_p_[0]) & 0x1) +#define UCSI_CONSTAT_PWR_READING_VALID(_p_) (((_p_[0]) & GENMASK(1, 1)) >> 1) +#define UCSI_CONSTAT_CURRENT_SCALE(_p_) (((_p_[0]) & GENMASK(4, 2)) >> 2) +#define UCSI_CONSTAT_PEAK_CURRENT(_p_) \ + ((get_unaligned_le32(_p_) & GENMASK(20, 5)) >> 5) +#define UCSI_CONSTAT_AVG_CURRENT(_p_) \ + ((get_unaligned_le32(&(_p_)[2]) & GENMASK(20, 5)) >> 5) +#define UCSI_CONSTAT_VOLTAGE_SCALE(_p_) \ + ((get_unaligned_le16(&(_p_)[4]) & GENMASK(8, 5)) >> 5) +#define UCSI_CONSTAT_VOLTAGE_READING(_p_) \ + ((get_unaligned_le32(&(_p_)[5]) & GENMASK(16, 1)) >> 1) } __packed; /* -------------------------------------------------------------------------- */
