[PATCH] dt-bindings: regulator: fan53555: add tcs,tcs4526

[PATCH] dt-bindings: regulator: fan53555: add tcs,tcs4526

[Rudi Heitbaum]

The driver has accepted tcs,tcs4526 since commit 5eee5eced95f
("regulator: fan53555: add tcs4526"), which added the compatible to both
the of_device_id and i2c_device_id tables for the TCS4526, a chip that
reports id 0 rather than the TCS4525's id 12.

The binding was converted to DT schema afterwards, in commit 6cea468b680e
("regulator: dt-bindings: Convert Fairchild FAN53555 to DT schema"), and
only picked up tcs,tcs4525. No in-tree DTS used the 4526 string at the
time, so nothing flagged the omission.

RK3399Pro boards use the TCS4526 for vdd_gpu and vdd_cpu_b, so a DTS
describing them fails dtbs_check today even though the driver binds
correctly.

Add the missing compatible.

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.
