6.15-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 55e52d055393f11ba0193975d3db87af36f4b273 ]
Add the missing HID supplies to avoid relying on other consumers to keep them on.
This also avoids the following warnings on boot:
i2c_hid_of 0-0010: supply vdd not found, using dummy regulator i2c_hid_of 0-0010: supply vddl not found, using dummy regulator i2c_hid_of 1-0015: supply vdd not found, using dummy regulator i2c_hid_of 1-002c: supply vdd not found, using dummy regulator i2c_hid_of 1-0015: supply vddl not found, using dummy regulator i2c_hid_of 1-002c: supply vddl not found, using dummy regulator i2c_hid_of 1-003a: supply vdd not found, using dummy regulator i2c_hid_of 1-003a: supply vddl not found, using dummy regulator
Note that VCC3B is also used for things like the modem which are not yet described so mark the regulator as always-on for now.
