From: Anand Ashok Dumbre <anand.ashok.dumbre@xxxxxxxxxx> The Xilinx AMS includes an ADC as well as on-chip sensors that can be used to sample external and monitor on-die operating conditions, such as temperature and supply voltage levels. Co-developed-by: Manish Narani <manish.narani@xxxxxxxxxx> Signed-off-by: Manish Narani <manish.narani@xxxxxxxxxx> Signed-off-by: Anand Ashok Dumbre <anand.ashok.dumbre@xxxxxxxxxx> Signed-off-by: Michael Tretter <m.tretter@xxxxxxxxxxxxxx> --- The patch series [0] for the AMS driver was applied, but the patch to add the node to the device tree was skipped. Thus, the driver is not probed at all. I added the xilinx_ams node to zynqmp-clk-ccf.dtsi, too, to allow the driver to find the firmware clock as mentioned in my review comment on the previous series.
