[PATCH] I2C: Move hwmon drivers (2/3)
Part 2: Move the driver files themselves.
Note that the patch "adds trailing whitespace", because it does move the
files as-is, and some files happen to have trailing whitespace.

The LM90 is a sensor chip made by National - * Semiconductor.

Complete datasheet can be - * obtained from Analog's website at: - * http://products.analog.com/products/info.asp?product=ADM1032 - * Among others, it has a higher accuracy than the LM90, much like the - * LM86 does. - * - * This driver also supports the MAX6657, MAX6658 and MAX6659 sensor - * chips made by Maxim.

The - * datasheet says we should either use the one-shot - * conversion register, which we don't want to do (disables - * hardware monitoring) or monitor the busy bit, which is - * impossible (we can't read the values and monitor that bit - * at the exact same time). So the solution used here is to - * read the high byte once, then the low byte, then the high - * byte again. If the new high byte matches the old one, - * then we have a valid reading. Else we have to read the low - * byte again, and now we believe we have a correct reading. - */ - oldh = i2c_smbus_read_byte_data(client, - LM90_REG_R_REMOTE_TEMPH); - data->temp11[0] = i2c_smbus_read_byte_data(client, - LM90_REG_R_REMOTE_TEMPL); - newh = i2c_smbus_read_byte_data(client, - LM90_REG_R_REMOTE_TEMPH); - if (newh != oldh) { - data->temp11[0] = i2c_smbus_read_byte_data(client, - LM90_REG_R_REMOTE_TEMPL); -#ifdef DEBUG - oldh = i2c_smbus_read_byte_data(client, - LM90_REG_R_REMOTE_TEMPH); - /* oldh is actually newer */ - if (newh != oldh) - dev_warn(&client->dev, "Remote temperature may be " - "wrong.\n"); -#endif - } - data->temp11[0] |= (newh << 8); - - data->temp11[1] = (i2c_smbus_read_byte_data(client, - LM90_REG_R_REMOTE_LOWH) << 8) + - i2c_smbus_read_byte_data(client, - LM90_REG_R_REMOTE_LOWL); - data->temp11[2] = (i2c_smbus_read_byte_data(client, - LM90_REG_R_REMOTE_HIGHH) << 8) + - i2c_smbus_read_byte_data(client, - LM90_REG_R_REMOTE_HIGHL); - data->alarms = i2c_smbus_read_byte_data(client, - LM90_REG_R_STATUS); - - data->last_updated = jiffies; - data->valid = 1; - } - - up(&data->update_lock); - - return data; -} - -static int __init sensors_lm90_init(void) -{ - return i2c_add_driver(&lm90_driver); -} - -static void __exit sensors_lm90_exit(void) -{ - i2c_del_driver(&lm90_driver); -} - -MODULE_AUTHOR("Jean Delvare <khali@linux-fr.org>"); -MODULE_DESCRIPTION("LM90/ADM1032 driver"); -MODULE_LICENSE("GPL"); - -module_init(sensors_lm90_init); -module_exit(sensors_lm90_exit); |
