Newsgroups	org.ozlabs.lists.linux-aspeed,org.infradead.lists.linux-arm-kernel,org.kernel.vger.linux-devicetree,org.kernel.vger.linux-kernel
Message-ID	<[email protected]>
Add alternative PCA9532 LED controllers at address 0x66 to support boards
populated with the PCA9532 instead of the primary PCA9552 at 0x67.
