Subject: [PATCH v2 4/6] mfd: bcm590xx: Add compatible for BCM59054
The BCM59056 supported by the bcm590xx driver is similar to the
BCM59054 MFD. Add a compatible for it in the driver, in preparation
for adding support for this chip in the bcm590xx regulator driver.
Signed-off-by: Artur Weber <aweber.kernel@...il.com>
