hwmon: (tmp401) Add OF device ID table

2022-05-18T07:42:47Z

[ Upstream commit 3481551f035725fdc46885425eac3ef9b58ae7b7 ] This driver doesn't have of_match_table. This makes the kernel module tmp401.ko lack alias patterns (e.g: of:N*T*Cti,tmp411) to match DT node of the supported devices hence this kernel module will not be automatically loaded. After adding of_match_table to this driver, the folllowing alias will be added into tmp401.ko. $ modinfo drivers/hwmon/tmp401.ko filename: drivers/hwmon/tmp401.ko ...... author: Hans de Goede alias: of:N*T*Cti,tmp435C* alias: of:N*T*Cti,tmp435 alias: of:N*T*Cti,tmp432C* alias: of:N*T*Cti,tmp432 alias: of:N*T*Cti,tmp431C* alias: of:N*T*Cti,tmp431 alias: of:N*T*Cti,tmp411C* alias: of:N*T*Cti,tmp411 alias: of:N*T*Cti,tmp401C* alias: of:N*T*Cti,tmp401 ......

hwmon: (tmp401) use smb word operations instead of 2 smb byte operations

2017-01-10T17:01:32Z

tmp401 separately read/wrote high and low bytes of temperature values while the hardware supports reading/writing those values in one operation. Driver has been modified to use word operations where possible. Tested with a tmp432 sensor on a mips64 platform. Signed-off-by: Jeroen De Wachter Signed-off-by: Guenter Roeck

hwmon: (tmp401) use permission-specific DEVICE_ATTR variants

2017-01-02T18:19:45Z

Use DEVICE_ATTR_RW for read/write attributes. This simplifies the source code, improves readbility, and reduces the chance of inconsistencies. The conversion was done automatically using coccinelle. It was validated by compiling both the old and the new source code and comparing its text, data, and bss size. Signed-off-by: Julia Lawall [groeck: Updated description] Signed-off-by: Guenter Roeck

hwmon: (tmp401) Do not auto-detect chip on I2C address 0x37

2015-05-29T20:37:06Z

I2C address 0x37 may be used by EEPROMs, which can result in false positives. Do not attempt to detect a chip at this address. Reviewed-by: Jean Delvare Cc: stable@vger.kernel.org # v4.0+ Signed-off-by: Guenter Roeck

hwmon: (tmp401) Detect TMP435 on all addresses it supports

2014-12-08T14:48:37Z

TMP435 supports a range of I2C addresses, not just 0x4c. Cc: Patrick Titiano Cc: Bartosz Golaszewski Reviewed-by: Jean Delvare Signed-off-by: Guenter Roeck

hwmon: (tmp401) Bail out from tmp401_probe() in case of write errors

2014-12-04T19:00:44Z

The return value of i2c_smbus_read_byte_data() is checked in tmp401_init_client(), but only a warning is printed and the device is registered anyway. This leads to devices being registered even if they cannot be physically detected. Bail out from probe in case of write errors and notify the user.

hwmon: (tmp401) Drop redundant safety on cache lifetime

2013-05-19T15:19:29Z

time_after (as opposed to time_after_equal) already ensures that the cache lifetime is at least as much as requested. There is no point in manually adding another jiffy to that value, and this can confuse the reader into wrong interpretation.
