If anyone has any objections, please let me know. ------------------ From: Vladimir Zapolskiy [ Upstream commit a76ce61d7225934b0a52c8172a8cd944002a8c6f ] When a consumer turns on/off a power domain dependent on another power domain in hardware, the parent power domain shall be turned on/off by the power domain provider as well, and to get it the power domain hardware hierarchy shall be described in the CAMCC driver. Establish the power domain hierarchy with a Titan GDSC set as a parent of all other GDSC power domains provided by the SM6350 camera clock controller to enforce a correct sequence of enabling and disabling power domains by the consumers, this fixes the CAMCC as a supplier of power domains to CAMSS IP and its driver.
