Subject: [PATCH v2] drm/panfrost: Prefix interrupt handlers' names
Date: Sat, 14 Dec 2019 01:59:52 -0300	[thread overview]
Message-ID: <20191214045952.9452-1-ezequiel@collabora.com> (raw)

Currently, the interrupt lines requested by Panfrost
use unmeaningful names, which adds some obscurity
to interrupt introspection (i.e. any tool based
on procfs' interrupts file).

In order to improve this, prefix each requested
interrupt with the module name: panfrost-{gpu,job,mmu}.

Signed-off-by: Ezequiel Garcia <ezequiel@collabora.com>

v2:
* Use consistent naming, as suggested by Alyssa, Neil and Robin.
