If anyone has any objections, please let me know. ------------------ From: Ahmad Khalifa [ Upstream commit 3b7f4bde06daaff391a374fc27c8163b2847de34 ] * Increase available bits, IN: 16 to 24, FAN: 8 to 12, TEMP: 6 to 12 * Reorder alarm/beep definitions to match in order to allow additional inputs in the future * Remove comments about 'unused' bits as probe() is a better reference Testing note: * Tested on nct6799 with IN/FAN/TEMP, and changing min/max/high/hyst, that triggers the corresponding alarms correctly. Good confirmation on the original mapping of the registers and masks. As to be expected, only 4 fans and 2 temps (fixed) have limits currently on nct6799 on my board. * Trouble with testing intrusion alarms and beeps, no way to confirm those. As I understand now, intrusion/caseopen is probably not connected on my board. And I haven't seen a buzzer on a board in ages.
