Message-Id: <1444215664-10921-1-git-send-email-srinivas.kandagatla@linaro.org> Date: Wed, 7 Oct 2015 12:01:04 +0100 From: Srinivas Kandagatla <srinivas.kandagatla@...aro.org> To: gregkh@...uxfoundation.org Cc: maxime.ripard@...e-electrons.com, linux-kernel@...r.kernel.org, andrew@...n.ch, wxt@...k-chips.com, stefan.wahren@...e.com, pantelis.antoniou@...sulko.com, maitysanchayan@...il.com, p.zabel@...gutronix.de, s.hauer@...gutronix.de, srinivas.kandagatla@...aro.org, linux-arm-kernel@...ts.infradead.org Subject: [PATCH v2 3/3] nvmem: core: add sysfs file mode flag in nvmem_config This patch adds mode variable to nvmem_config structure which will allow providers to specify the permissions for the sysfs binary file. This mode is applied on top of root-only access permissions set by the core. Having this flag would give more flexibility to providers to decide which permissions to set on the sysfs binary file entry.
