Subject: [PATCH v3 4/6] ARM: dts: add GXP Support for fans and SPI
From: Nick Hawkins <nick.hawkins@....com>
Reorganize the base address of AHB to accommodate the SPI and fan driver
register requirements. Add the hpe,gxp-spifi and hpe,gxp-fan-ctrl
compatibles. Add comments to make the register range more clear.
Signed-off-by: Nick Hawkins <nick.hawkins@....com>
