From b7f1f7b2523a6a4382f12fe953380b847b80e09d Mon Sep 17 00:00:00 2001 From: Ahmad Khalifa Date: Wed, 2 Aug 2023 19:58:21 +0100 Subject: [PATCH] hwmon: (nct6775) Additional TEMP registers for nct6799 Additional TEMP registers for nct6798d, nct6799d-r and nct6796d-s This allows the max/max_hyst/crit attributes to be shown/stored * Increase NUM_TEMP from 10 to 12 * Separate TEMP/MON_TEMP/OVER/HYST/CRIT registers * Rename "PECI Calibration" to include "TSI" too * Update ALARM/BEEP bits for temps for 6799 * For 6799, keep temp_fixed_num at 6, but increase num_temp_alarms/num_temp_beeps to 7/8 Tested with NCT6799D-R showing additional sysfs attributes: * temp3-temp8: max/max_hyst/beep/alarm * temp3-temp6: crit/offset Signed-off-by: Ahmad Khalifa Link: https://lore.kernel.org/r/20230802185820.3642399-1-ahmad@khalifa.ws [groeck: Addressed cosmetic checkpatch complaints] Signed-off-by: Guenter Roeck --- drivers/hwmon/nct6775-core.c | 150 ++++++++++++++++++++++++++++------- drivers/hwmon/nct6775.h | 2 +- 2 files changed, 121 insertions(+), 31 deletions(-) diff --git a/drivers/hwmon/nct6775-core.c b/drivers/hwmon/nct6775-core.c index 33533d95cf48..02a71244fc3b 100644 --- a/drivers/hwmon/nct6775-core.c +++ b/drivers/hwmon/nct6775-core.c @@ -617,6 +617,28 @@ static const char *const nct6796_temp_label[] = { static const u16 NCT6796_REG_TSI_TEMP[] = { 0x409, 0x40b }; +static const u16 NCT6798_REG_TEMP[] = { + 0x27, 0x150, 0x670, 0x672, 0x674, 0x676, 0x678, 0x67a}; + +static const u16 NCT6798_REG_TEMP_SOURCE[] = { + 0x621, 0x622, 0xc26, 0xc27, 0xc28, 0xc29, 0xc2a, 0xc2b }; + +static const u16 NCT6798_REG_TEMP_MON[] = { + 0x73, 0x75, 0x77, 0x79, 0x7b, 0x7d, 0x4a0 }; +static const u16 NCT6798_REG_TEMP_OVER[] = { + 0x39, 0x155, 0xc1a, 0xc1b, 0xc1c, 0xc1d, 0xc1e, 0xc1f }; +static const u16 NCT6798_REG_TEMP_HYST[] = { + 0x3a, 0x153, 0xc20, 0xc21, 0xc22, 0xc23, 0xc24, 0xc25 }; + +static const u16 NCT6798_REG_TEMP_CRIT[32] = { + 0x135, 0x235, 0x335, 0x835, 0x935, 0xa35, 0xb35, 0 }; + +static const u16 NCT6798_REG_TEMP_ALTERNATE[32] = { + 0x490, 0x491, 0x492, 0x493, 0x494, 0x495, 0x496, 0, + 0, 0, 0, 0, 0x4a2, 0, 0, 0, + 0, 0x400, 0x401, 0x402, 0x404, 0x405, 0x406, 0x407, + 0x408, 0x419, 0x41a, 0x4f4, 0x4f5 }; + static const char *const nct6798_temp_label[] = { "", "SYSTIN", @@ -655,11 +677,14 @@ static const char *const nct6798_temp_label[] = { #define NCT6798_TEMP_MASK 0xbfff0ffe #define NCT6798_VIRT_TEMP_MASK 0x80000c00 +static const u16 NCT6799_REG_ALARM[NUM_REG_ALARM] = { + 0x459, 0x45A, 0x45B, 0x568, 0x45D, 0xc01 }; + static const s8 NCT6799_ALARM_BITS[NUM_ALARM_BITS] = { 0, 1, 2, 3, 8, -1, 20, 16, 17, 24, 25, 26, /* in0-in11 */ 27, 28, 29, 30, 31, -1, -1, -1, -1, -1, -1, -1, /* in12-in23 */ 6, 7, 11, 10, 23, 33, -1, -1, -1, -1, -1, -1, /* fan1-fan12 */ - 4, 5, 13, -1, -1, -1, -1, -1, -1, -1, -1, -1, /* temp1-temp12 */ + 4, 5, 40, 41, 42, 43, 44, -1, -1, -1, -1, -1, /* temp1-temp12 */ 12, 9, /* intr0-intr1 */ }; @@ -667,10 +692,11 @@ static const s8 NCT6799_BEEP_BITS[NUM_BEEP_BITS] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, /* in0-in11 */ 12, 13, 14, 15, 34, 35, -1, -1, -1, -1, -1, -1, /* in12-in23 */ 25, 26, 27, 28, 29, -1, -1, -1, -1, -1, -1, -1, /* fan1-fan12 */ - 16, 17, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, /* temp1-temp12 */ + 16, 17, 18, 19, 20, 21, 22, 23, -1, -1, -1, -1, /* temp1-temp12 */ 30, 31, 24 /* intr0-intr1, beep_en */ }; +/* PECI Calibration only for NCT6799D, not NCT6796D-S */ static const char *const nct6799_temp_label[] = { "", "SYSTIN", @@ -700,8 +726,8 @@ static const char *const nct6799_temp_label[] = { "Agent1 Dimm1", "BYTE_TEMP0", "BYTE_TEMP1", - "PECI Agent 0 Calibration", /* undocumented */ - "PECI Agent 1 Calibration", /* undocumented */ + "PECI/TSI Agent 0 Calibration", + "PECI/TSI Agent 1 Calibration", "", "Virtual_TEMP" }; @@ -3869,13 +3895,9 @@ int nct6775_probe(struct device *dev, struct nct6775_data *data, case nct6795: case nct6796: case nct6797: - case nct6798: - case nct6799: data->in_num = 15; data->pwm_num = (data->kind == nct6796 || - data->kind == nct6797 || - data->kind == nct6798 || - data->kind == nct6799) ?
