Hi Guenter, thanks a lot for your deep review and fix proposals. As a result of it, appended to this mail there's an updated patch intended to be applied ontop of your patches given yesterday. Hope that it will not get corrupted this time.. :-/ The compilation against kernel 2.6.39 with all patches applied does work without warnings, and my f75387 still works (but as before without connected fans...). >> Obviously, Harald Dunkel requested the f75387 implementation in 2007. >> Do you think it would be a good idea to contact him asking for a fan >> test on his board..? >> > Definitely. Worst case he does not reply or no longer has the hardware. > Okay sounds good, so I'll contact him about this in a separate mail.. ;-) -- Bjoern Gerhart diff -uNr linux-2.6.39-5patched/drivers/hwmon/f75375s.c linux-2.6.39/drivers/hwmon/f75375s.c --- linux-2.6.39-5patched/drivers/hwmon/f75375s.c 2011-12-09 15:41:01.000000000 +0100 +++ linux-2.6.39/drivers/hwmon/f75375s.c 2011-12-09 21:41:10.000000000 +0100 @@ -1,6 +1,6 @@ /* - * f75375s.c - driver for the Fintek F75375/SP and F75373 - * hardware monitoring features + * f75375s.c - driver for the Fintek F75375/SP, F75373 and + * F75387SG/RG hardware monitoring features * Copyright (C) 2006-2007 Riku Voipio * * Datasheets available at: @@ -10,6 +10,9 @@ * * f75373: * http://www.fintek.com.tw/files/productfiles/F75373_V025P.pdf + * + * f75387: + * http://www.fintek.com.tw/files/productfiles/F75387_V027P.pdf * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by @@ -40,7 +43,7 @@ /* Addresses to scan */ static const unsigned short normal_i2c[] = { 0x2d, 0x2e, I2C_CLIENT_END }; -enum chips { f75373, f75375 }; +enum chips { f75373, f75375, f75387 }; /* Fintek F75375 registers */ #define F75375_REG_CONFIG0 0x0 @@ -59,6 +62,7 @@ #define F75375_REG_VOLT_LOW(nr) (0x21 + (nr) * 2) #define F75375_REG_TEMP(nr) (0x14 + (nr)) +#define F75387_REG_TEMP11_LSB(nr) (0x1a + (nr)) #define F75375_REG_TEMP_HIGH(nr) (0x28 + (nr) * 2) #define F75375_REG_TEMP_HYST(nr) (0x29 + (nr) * 2) @@ -78,8 +82,11 @@ #define F75375_REG_PWM1_DROP_DUTY 0x6B #define F75375_REG_PWM2_DROP_DUTY 0x6C -#define FAN_CTRL_LINEAR(nr) (4 + nr) +#define F75375_FAN_CTRL_LINEAR(nr) (4 + nr) +#define F75387_FAN_CTRL_LINEAR(nr) (1 + ((nr) * 4)) #define FAN_CTRL_MODE(nr) (4 + ((nr) * 2)) +#define F75387_FAN_DUTY_MODE(nr) (2 + ((nr) * 4)) +#define F75387_FAN_MANU_MODE(nr) ((nr) * 4) /* * Data structures and manipulation thereof @@ -108,7 +115,12 @@ u8 pwm[2]; u8 pwm_mode[2]; u8 pwm_enable[2]; - s8 temp[2]; + /* + * f75387: For remote temperature reading, it uses signed 11-bit + * values with LSB = 0.125 degree Celsius, left-justified in 16-bit + * registers.
