hwmon: lm70: simplify with spi_get_device_match_data()

2024-06-08T23:07:32+00:00

Use spi_get_device_match_data() helper to simplify a bit the driver.
Also kernel_ulong_t type is preferred for kernel code over uintptr_t
(needed for the cast).

hwmon: (lm70) fix links in doc and comments

2024-04-28T17:07:34+00:00

Update links in the documentation and in-code comments which point to
the datasheet.

The current links don't work because National Semiconductor (which is the
original manufacturer of this chip) has been a part of Texas Instruments
since 2011 and http://www.national.com/ doesn't work anymore.

hwmon: (lm70) Add ti,tmp125 support

2022-02-28T01:03:19+00:00

The TMP125 is a 2 degree Celsius accurate Digital
Temperature Sensor with a SPI interface.

The temperature register is a 16-bit, read-only register.
The MSB (Bit 15) is a leading zero and never set. Bits 14
to 5 are the 1+9 temperature data bits in a two's
complement format. Bits 4 to 0 are useless copies of
Bit 5 value and therefore ignored.

This was tested on a Aerohive HiveAP-350.

Bonus: lm70 supports TMP122/TMP124 as well.
I added them to the Kconfig module description.

hwmon: (lm70) Revert "hwmon: (lm70) Add support for ACPI"

2021-06-17T11:21:44+00:00

This reverts commit b58bd4c6dfe709646ed9efcbba2a70643f9bc873.

None of the ACPI IDs introduced with the reverted patch is a valid ACPI
device ID. Any ACPI users of this driver are advised to use PRP0001 and
a devicetree-compatible device identification.

hwmon: (lm70) Use device_get_match_data()

2021-01-28T21:46:08+00:00

Use the more modern API to get the match data out of the of match table.
This saves some code, lines, and nicely avoids referencing the match
table when it is undefined with configurations where CONFIG_OF=n.
