Subject: [PATCH 5/5] BSC9131rdb/dts: Add nodes for supporting AIC and AD PHY
From: Akhil Goyal <akhil.goyal@...escale.com>
BSC9131 is a hetrogenous system where Antenna interface controller
(AIC) is a part of DSP subsystem. But its configuration is done from
PA side. So a DSP node is added with appropriate CCSR address visible
to PA and hence the address space for AIC will be visible to PA.
BSC9131 support 3 AIC lanes for ADI interface and 3 for MAXIM type of
interface. This patch support only ADI lanes.
This patch also provide node for rfphy which includes control gpios
for RFIC and various SPI parameters required for accessing the ADI
phy registers. ADI chip is connected to espi-1 and control gpios
are controlled by gpio-0 and gpio-1
Currently on BSC9131, the DTS support only one rfphy and it is
attached to AIC lane 3 for LTE and WCDMA networks.
