This driver built just fine in gentoo-sources-5.5.5 and earlier.
Comment 1 Mike Pagano gentoo-dev 2020-03-05 14:41:54 UTC
Please attach the output of emerge --info
Have you tried with 5.5.7 ?

5.5.7 is currently installed (though not active), but I have not re-enabled the tmp513 driver.  I'll give it a shot and report.

OK, I can confirm the problem is still present in 5.5.7.

Sorry, my responses are slow. I'm in healthcare and it's been a tough week.
Can you also attach your .config, please?

Keep up the good work, man.  You guys have it rougher than anyone right now.


Config will be attached in a moment, but note that this is with CONFIG_SENSORS_TMP513 disabled in order to be able to build it.

CONFIG_SENSORS_TMP513 disabled to allow building
Comment 7 Mike Pagano gentoo-dev 2020-03-20 23:40:37 UTC
Thanks for the .config. It fails for me also with the driver enabled. I'll be looking at this over the weekend.
Comment 8 Mike Pagano gentoo-dev 2020-03-21 22:26:13 UTC
TLDR: I was able to compile the driver with CONFIG_REGMAP=y and CONFIG_REGMAP_I2C=y

But to get REGMAP_I2C selected, I had to select TMP108 (that's an upstream patch that's needed.)

Long version

First error:
error: variable ‘tmp51x_regmap_config’ has initializer but incomplete type

Code: tmp513.c
static struct regmap_config tmp51x_regmap_config = {

Problem:
What that error means is regmap_config is undefined

But, tmp513.c has #include <linux/regmap.h>

Let's look in include/linux/regmap.h
Here you find on line 352 (5.5.11), the regmap_config is defined
struct regmap_config

If you look above it's only defined if CONFIG_REGMAP is defined.

So,  I needed to define CONFIG_REGMAP.

Then, i got this error:
undefined reference to `__devm_regmap_init_i2c'

And I needed to compile with: CONFIG_REGMAP_I2C
But I should not have to select this. The SENSOR_TMP513 is missing in the Kconfig here. 

So I had to choose TMP108, to get REGMAP_I2C selected. Ug. 

Then it all worked. So, I think there's a Kconfig patch needed here :)

Can you try that workaround and let me know how it goes?
Comment 9 Phil Stracchino (Unix Ronin) 2020-03-21 22:46:52 UTC
So to make sure I understand correctly:

To make CONFIG_SENSORS_TMP513 work, it is necessary to set CONFIG_SENSORS_TMP108 *AND* edit include/linux/regmap.h to manually define CONFIG_REGMAP?
