Subject: [PATCH 0/3] regulator: fan53555: tcs4525 fix and cleanup
Date: Tue, 11 May 2021 17:13:32 -0400
The tcs4525 voltage calculation is incorrect, which leads to a deadlock
on the rk3566-quartz64 board when loading cpufreq.
Fix the voltage calculation to correct the deadlock.
While we are at it, add a safety check and clean up the function names
to be more accurate.

Subject: [PATCH 1/3] regulator: fan53555: fix TCS4525 voltage calulation
Date: Tue, 11 May 2021 17:13:33 -0400
The TCS4525 has 128 voltage steps. With the calculation set to 127 the
most significant bit is disregarded which leads to a miscalculation of
the voltage by about 200mv.
Fix the calculation to end deadlock on the rk3566-quartz64 which uses
this as the cpu regulator.

From: Rudi Heitbaum <rudi@heitbaum.com>
Subject: [PATCH v2] regulator: fan53555: add tcs4526
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.

Subject: [PATCH 2/2] regulator: fan53555: Cleanup unused define and redundant assignment
Date: Mon, 17 May 2021 09:03:18 +0800
TCS_VSEL_NSEL_MASK is not used so remove it.
Also remove redundant assignment for di->slew_reg.
