BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=204807 Signed-off-by: Denis Pauk Co-developed-by: Bernhard Seibold Signed-off-by: Bernhard Seibold Cc: Andy Shevchenko Cc: Guenter Roeck --- Changes in v7: - Without changes. Changes in v6: - Split patch with replace direct calls to function pointers. Changes in v5: - Without changes. Changes in v4: - Fix naming conflict with inb, outb by add sio prefix to callbacks in nct6775_sio_data. Changes in v3: - Use nct6775 function pointers in struct nct6775_data instead direct calls. - make function declarations one line. Changes in v2: - Split changes to separate patches. - Rearrange code for directly use struct nct6775_sio_data in superio_*() functions. --- drivers/hwmon/nct6775.c | 189 ++++++++++++++++++++++------------------ 1 file changed, 104 insertions(+), 85 deletions(-) diff --git a/drivers/hwmon/nct6775.c b/drivers/hwmon/nct6775.c index 5bd15622a85f..9b503c88e20d 100644 --- a/drivers/hwmon/nct6775.c +++ b/drivers/hwmon/nct6775.c @@ -133,30 +133,46 @@ MODULE_PARM_DESC(fan_debounce, "Enable debouncing for fan RPM signal");

Changes in v6: - Split patch with replace direct calls to function pointers. Changes in v5: - Without changes. Changes in v4: - Fix naming conflict with inb, outb by add sio prefix to callbacks in nct6775_sio_data. Changes in v3: - Use nct6775 function pointers in struct nct6775_data instead direct calls. - make function declarations one line. Changes in v2: - Split changes to separate patches. - Rearrange code for directly use struct nct6775_sio_data in superio_*() functions. --- drivers/hwmon/nct6775.c | 283 ++++++++++++++++++++-------------------- 1 file changed, 143 insertions(+), 140 deletions(-) diff --git a/drivers/hwmon/nct6775.c b/drivers/hwmon/nct6775.c index 9b503c88e20d..4253eed7f5b0 100644 --- a/drivers/hwmon/nct6775.c +++ b/drivers/hwmon/nct6775.c @@ -1232,6 +1232,10 @@ struct nct6775_data { u8 fandiv1;

On mainboards that support this way of accessing the chip, the driver will usually not work without this option since in these mainboards, ACPI will mark the I/O port as used. Code uses ACPI firmware interface to communicate with sensors with ASUS motherboards: * PRIME B460-PLUS, * ROG CROSSHAIR VIII IMPACT, * ROG STRIX B550-E GAMING, * ROG STRIX B550-F GAMING, * ROG STRIX B550-F GAMING (WI-FI), * ROG STRIX Z490-I GAMING, * TUF GAMING B550M-PLUS, * TUF GAMING B550M-PLUS (WI-FI), * TUF GAMING B550-PLUS, * TUF GAMING X570-PLUS, * TUF GAMING X570-PRO (WI-FI).

Tashkinov Tested-by: Vittorio Roberto Alfieri Tested-by: Sahan Fernando Cc: Andy Shevchenko Cc: Guenter Roeck --- Changes in v7: - Remove unrequred & 0xff with int8 variables. - Make ASUSWMI_UNSUPPORTED_METHOD as default value for WMI responce, before run wmi_evaluate_method(). - Rename ASUSWMI_MGMT2_GUID to ASUSWMI_MONITORING_GUID. - Replace checks of 'err != -EINVAL' with 'err >= 0' for match_string result. Changes in v6: - Minimaze codes inside code inside defined(CONFIG_ACPI_WMI). Changes in v5: - Use IS_ENABLED(CONFIG_ACPI_WMI) instead defined(CONFIG_ACPI_WMI) Changes in v4: - Fix build without ACPI WMI. Changes in v3: - Remove unrequired type conversions. - Save result of match_string before check. Changes in v2: - Split changes to separate patches. - Limit WMI usage by DMI_BOARD_NAME in checked ASUS motherboards. --- drivers/hwmon/Kconfig | 1 + drivers/hwmon/nct6775.c | 230 ++++++++++++++++++++++++++++++++++++---- 2 files changed, 210 insertions(+), 21 deletions(-) diff --git a/drivers/hwmon/Kconfig b/drivers/hwmon/Kconfig index e3675377bc5d..9eefb1014b53 100644 --- a/drivers/hwmon/Kconfig +++ b/drivers/hwmon/Kconfig @@ -1423,6 +1423,7 @@ config SENSORS_NCT6683 config SENSORS_NCT6775 tristate "Nuvoton NCT6775F and compatibles" depends on !PPC + depends on ACPI_WMI || ACPI_WMI=n select HWMON_VID help If you say yes here you get support for the hardware monitoring diff --git a/drivers/hwmon/nct6775.c b/drivers/hwmon/nct6775.c index 4253eed7f5b0..46262d9d3bd9 100644 --- a/drivers/hwmon/nct6775.c +++ b/drivers/hwmon/nct6775.c @@ -55,6 +55,7 @@ #include #include #include +#include #include "lm75.h" #define USE_ALTERNATE @@ -132,10 +133,13 @@ MODULE_PARM_DESC(fan_debounce, "Enable debouncing for fan RPM signal");
