Subject: [PATCH v4 0/1] gpio: add driver for Mellanox BlueField GPIO controller
Date: Thu, 21 Feb 2019 16:32:54 -0500 [thread overview]
Message-ID: <cover.1550783880.git.sramani@mellanox.com> (raw)
Changes since v3
- the naming scheme has been fixed to remove double underscores and use
standard variable names
- the locking has been updated to protect the entire read/modify
operations.
Regarding the suggested use of the generic MMIO library, I noticed that
bgpio_init only allows for either dirin or dirout to be set, never both.
But since our controller has 2 separate registers, using bgpio_init
might not be possible here.
