Hi all, Here's a rough first cut at converting the adm1021.c driver over to sysfs. The second driver in, and already we're violating the published documentation :) There's a die_code value that isn't in the docs, and I have no idea how to handle the *prec variables that can be read from a adm1023 chip. Also, I'm pretty sure the write logic is wrong, and the scale of the read values is also incorrect, but as I don't have this hardware, I would really appreciate any fixes for this patch. The patch should apply cleanly to 2.5.66 and any later -bk trees. thanks, greg k-h diff -Nru a/drivers/i2c/chips/adm1021.c b/drivers/i2c/chips/adm1021.c --- a/drivers/i2c/chips/adm1021.c Thu Mar 27 22:32:52 2003 +++ b/drivers/i2c/chips/adm1021.c Thu Mar 27 22:32:52 2003 @@ -53,34 +53,34 @@ /* The adm1021 registers */ /* Read-only */ -#define ADM1021_REG_TEMP 0x00 -#define ADM1021_REG_REMOTE_TEMP 0x01 -#define ADM1021_REG_STATUS 0x02 -#define ADM1021_REG_MAN_ID 0x0FE /* 0x41 = AMD, 0x49 = TI, 0x4D = Maxim, 0x23 = Genesys , 0x54 = Onsemi*/ -#define ADM1021_REG_DEV_ID 0x0FF /* ADM1021 = 0x0X, ADM1023 = 0x3X */ -#define ADM1021_REG_DIE_CODE 0x0FF /* MAX1617A */ +#define ADM1021_REG_TEMP 0x00 +#define ADM1021_REG_REMOTE_TEMP 0x01 +#define ADM1021_REG_STATUS 0x02 +#define ADM1021_REG_MAN_ID 0x0FE /* 0x41 = AMD, 0x49 = TI, 0x4D = Maxim, 0x23 = Genesys , 0x54 = Onsemi*/ +#define ADM1021_REG_DEV_ID 0x0FF /* ADM1021 = 0x0X, ADM1023 = 0x3X */ +#define ADM1021_REG_DIE_CODE 0x0FF /* MAX1617A */ /* These use different addresses for reading/writing */ -#define ADM1021_REG_CONFIG_R 0x03 -#define ADM1021_REG_CONFIG_W 0x09 -#define ADM1021_REG_CONV_RATE_R 0x04 -#define ADM1021_REG_CONV_RATE_W 0x0A +#define ADM1021_REG_CONFIG_R 0x03 +#define ADM1021_REG_CONFIG_W 0x09 +#define ADM1021_REG_CONV_RATE_R 0x04 +#define ADM1021_REG_CONV_RATE_W 0x0A /* These are for the ADM1023's additional precision on the remote temp sensor */ -#define ADM1021_REG_REM_TEMP_PREC 0x010 -#define ADM1021_REG_REM_OFFSET 0x011 -#define ADM1021_REG_REM_OFFSET_PREC 0x012 -#define ADM1021_REG_REM_TOS_PREC 0x013 -#define ADM1021_REG_REM_THYST_PREC 0x014 +#define ADM1021_REG_REM_TEMP_PREC 0x010 +#define ADM1021_REG_REM_OFFSET 0x011 +#define ADM1021_REG_REM_OFFSET_PREC 0x012 +#define ADM1021_REG_REM_TOS_PREC 0x013 +#define ADM1021_REG_REM_THYST_PREC 0x014 /* limits */ -#define ADM1021_REG_TOS_R 0x05 -#define ADM1021_REG_TOS_W 0x0B -#define ADM1021_REG_REMOTE_TOS_R 0x07 -#define ADM1021_REG_REMOTE_TOS_W 0x0D -#define ADM1021_REG_THYST_R 0x06 -#define ADM1021_REG_THYST_W 0x0C -#define ADM1021_REG_REMOTE_THYST_R 0x08 -#define ADM1021_REG_REMOTE_THYST_W 0x0E +#define ADM1021_REG_TOS_R 0x05 +#define ADM1021_REG_TOS_W 0x0B +#define ADM1021_REG_REMOTE_TOS_R 0x07 +#define ADM1021_REG_REMOTE_TOS_W 0x0D +#define ADM1021_REG_THYST_R 0x06 +#define ADM1021_REG_THYST_W 0x0C +#define ADM1021_REG_REMOTE_THYST_R 0x08 +#define ADM1021_REG_REMOTE_THYST_W 0x0E /* write-only */ -#define ADM1021_REG_ONESHOT 0x0F +#define ADM1021_REG_ONESHOT 0x0F /* Conversions.
