+Qualcomm Technologies, Inc. GENI Serial Engine Driver
+
+GENI Serial Engine Driver manages the GENI firmware based Qualcomm Universal
+Peripheral (QUP) Wrapper. GENI SE Driver also manages the common aspects of
+individual Serial Engines that composes the QUP Wrapper.
Bindings describe h/w, not drivers.
I will update the bindings to describe just the h/w and remove any
driver description.
+
+Required properties:
+- compatible: Must be "qcom,geni-se-qup".
Only one version of the h/w?
There is more than one hardware version. The h/w provides registers to
identify the hardware version. The driver currently uses those registers
to support any version-specific operations. So I am not sure if the
compatible field needs to reflect the h/w version.
+- reg: Must contain QUP register address and length.
+
+Example:
+ qup_0: qcom,geni_se_qup_0@8c0000 {
Don't use '_' in node names.
I will update the bindings to not use '_'.
+ compatible = "qcom,geni-se-qup";
+ reg = <0x8c0000 0x6000>;
+ }
