hwmon: (pmbus/core) Treat parameters as paged if on multiple pages

2019-06-25T03:34:52Z

[ Upstream commit 4a60570dce658e3f8885bbcf852430b99f65aca5 ] Some chips have attributes which exist on more than one page but the attribute is not presently marked as paged. This causes the attributes to be generated with the same label, which makes it impossible for userspace to tell them apart. Marking all such attributes as paged would result in the page suffix being added regardless of whether they were present on more than one page or not, which might break existing setups. Therefore, we add a second check which treats the attribute as paged, even if not marked as such, if it is present on multiple pages.

hwmon: (pmbus) associate PMBUS_SKIP_STATUS_CHECK with driver data

2019-02-18T22:23:29Z

Current code compares device name with name in i2c_device_id to decide whether PMBUS_SKIP_STATUS_CHECK should be set in pmbus_platform_data, which makes adding new devices with PMBUS_SKIP_STATUS_CHECK should also modify code in pmbus_probe(). This patch adds pmbus_device_info to save pages and flags. Its pointer is put in driver_data of i2c_device_id, which makes adding new device more straightforward.

hwmon: (pmbus/tps53679) Fix driver info initialization in probe routine

2019-02-18T22:22:52Z

Fix tps53679_probe() by using dynamically allocated "pmbus_driver_info" structure instead of static. Usage of static structures causes overwritten of the field "vrm_version", in case the system is equipped with several tps53679 devices with the different "vrm_version". In such case the last probed device overwrites this field for all others.

hwmon: (adm1275) Allow setting shunt reg value

2018-12-03T00:25:28Z

The ADM series of hotswap controllers support extending the current measurement range by using a sensing resistor value other than the typical 1 mOhm. For example, using a 0.5 mOhm sensing resistor doubles the maximal current can be measured. Current driver assumes a shunt resistor value of 1 mOhm in calculation, meaning for other resistor values, hwmon will report scaled current/power measurements. This patch parses device tree parameter "shunt-resistor-micro-ohms", if there is one. Signed-off-by: Kun Yi Signed-off-by: Guenter Roeck

hwmon: (pmbus) Fix page count auto-detection.

2018-10-15T19:44:36Z

Devices with compatible="pmbus" field have zero initial page count, and pmbus_clear_faults() being called before the page count auto- detection does not actually clear faults because it depends on the page count. Non-cleared faults in its turn may fail the subsequent page count auto-detection. This patch fixes this problem by calling pmbus_clear_fault_page() for currently set page and calling pmbus_clear_faults() after the page count was detected.

hwmon: (pmbus) remove redundant 'default n' from Kconfig

2018-10-12T03:08:16Z

'default n' is the default value for any bool or tristate Kconfig setting so there is no need to write it explicitly. Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO is not set' for visible symbols") the Kconfig behavior is the same regardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ... Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Guenter Roeck
