Subject: [PATCH 2/2 v2] regulator: fan53555: add tcs4526
Date: Wed, 2 Jun 2021 11:29:47 +0000 [thread overview]
Message-ID: <20210602112943.GA119@5f9be87369f8> (raw)
In-Reply-To: <20210602112452.GA98@5f9be87369f8>
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.
