| |
Problem: adm1272 and adm1278 supports temperature sampling. The current way of enabling it requires the user manually unbind the device from the driver, flip the temperature sampling control bit and then bind the device back to the driver. It would be nice if we can control this in a better way by reading the dt.
Solution: Introducing device tree binding analog,temp1-enable. If the flag is set, flip the temp1_en control bit on probing.
Testing: make dt_binding_check
Signed-off-by: Chu Lin <linchuyuan@google.com> --- ChangeLog v1->v2: - Rename adm1272-adm1278-temp1-en to analog-temperature1-enable
ChangeLog v2->v3: - Rename analog-temperature1-enable analog,temp1-enable
