From mboxrd@z Thu Jan 1 00:00:00 1970 From: Shravan Kumar Ramani Subject: [PATCH v4 0/1] gpio: add driver for Mellanox BlueField GPIO controller Date: Thu, 21 Feb 2019 16:32:54 -0500 Message-ID: Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Linus Walleij , Bartosz Golaszewski Cc: Shravan Kumar Ramani , linux-gpio@vger.kernel.org, linux-kernel@vger.kernel.org List-Id: linux-gpio@vger.kernel.org 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.
