For rk3399pro boards the tcs4526 regulator supports the vdd_gpu regulator. The tcs4526 regulator has a chip id of <0>. Add the compatibile tcs,tcs4526 without this patch, the dmesg output is: fan53555-regulator 0-0010: Chip ID 0 not supported! fan53555-regulator 0-0010: Failed to setup device! fan53555-regulator: probe of 0-0010 failed with error -22 with this patch, the dmesg output is: vdd_gpu: supplied by vcc5v0_sys The regulators are described as: - Dedicated power management IC TCS4525 - Lithium battery protection chip TCS4526 This has been tested with a Radxa Rock Pi N10.
