Mark the interrupt as IRQF_SHARED to permit multiple counter channels to share the same TCB IRQ line. Each Timer/Counter Block (TCB) instance shares a single IRQ line among its three internal channels. When multiple counter channels (e.g., counter@0 and counter@1) within the same TCB are enabled, the second call to devm_request_irq() fails because the IRQ line is already requested by the first channel.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
