counter: Rename counter_count_function to counter_function

2021-08-09T19:17:36+00:00

The phrase "Counter Count function" is verbose and unintentionally implies that function is a Count extension. This patch adjusts the Counter subsystem code to use the more direct "Counter function" phrase to make the intent of this code clearer.

counter: Rename counter_signal_value to counter_signal_level

2021-08-09T19:17:36+00:00

Signal values will always be levels so let's be explicit it about it to make the intent of the code clear.

counter: Standardize to ERANGE for limit exceeded errors

2021-08-09T19:17:36+00:00

ERANGE is a semantically better error code to return when an argument value falls outside the supported limit range of a device.

counter: Return error code on invalid modes

2021-08-09T19:17:36+00:00

Only a select set of modes (function, action, etc.) are valid for a given device configuration. This patch ensures that invalid modes result in a return -EINVAL. Such a situation should never occur in reality, but it's good to define a default switch case for the sake of making the intent of the code clear.

counter: 104-quad-8: Return error when invalid mode during ceiling_write

2021-08-09T19:17:36+00:00

The 104-QUAD-8 only has two count modes where a ceiling value makes sense: Range Limit and Modulo-N. Outside of these two modes, setting a ceiling value is an invalid operation -- so let's report it as such by returning -EINVAL.

counter: interrupt-cnt: Add const qualifier for actions_list array

2021-06-13T16:00:18+00:00

The struct counter_synapse actions_list member expects a const enum counter_synapse_action array. This patch renames interrupt_cnt_synapse_actionss to interrupt_cnt_synapse_actions and adds a const qualifier to match actions_list.
