[srinivas.kandagatla]

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

Hi Greg,

Here are some nvmem enhancements, cleanup, and update to documentation
mostly done by Andrey, it also adds support to snvs-lpgpr on i.MX7

Can you queue them up for 4.17.

Thanks,
Srini

Andrey Smirnov (21):
  nvmem: Document struct nvmem_config
  nvmem: core: Allow specifying device name verbatim
  nvmem: Introduce devm_nvmem_(un)register()
  nvmem: vf610-ocotp: Convert to use devm_nvmem_register()
  nvmem: imx-ocotp: Convert to use devm_nvmem_register()
  nvmem: uniphier-efuse: Convert to use devm_nvmem_register()
  nvmem: snvs_lgpr: Convert to use devm_nvmem_register()
  nvmem: rockchip-efuse: Convert to use devm_nvmem_register()
  nvmem: mtk-efuse: Convert to use devm_nvmem_register()
  nvmem: meson-mx-efuse: Convert to use devm_nvmem_register()
  nvmem: meson-efuse: Convert to use devm_nvmem_register()
  nvmem: lpc18xx_otp: Convert to use devm_nvmem_register()
  nvmem: imx-iim: Convert to use devm_nvmem_register()
  nvmem: bcm-ocotp: Convert to use devm_nvmem_register()
  nvmem: qfprom: Convert to use devm_nvmem_register()
  nvmem: snvs_lpgpr: Convert commas to semicolons
  nvmem: rockchip-efuse: Make use of of_device_get_match_data()
  nvmem: vf610-ocotp: Do not use "&pdev->dev" explicitly
  nvmem: rockchip-efuse: Do not use "&pdev->dev" explicitly
  nvmem: imx-iim: Do not use "&pdev->dev" explicitly
  nvmem: bcm-ocotp: Do not use "&pdev->dev" explicitly

Andrey Yurovsky (1):
  nvmem: add i.MX7 support to snvs-lpgpr

Dong Aisheng (2):
  dt-bindings: nvmem: imx-ocotp: update the binding to reflect data
    cells
  nvmem: imx-ocotp: remove unused dead code

Icenowy Zheng (1):

[PATCH 02/25] nvmem: core: Allow specifying device name verbatim

[srinivas.kandagatla-QSEj5FYQhm4dnm+yROfE0A]

From: Andrey Smirnov <andrew.smirnov-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

Add code to allow avoid having nvmem core append a numeric suffix to
the end of the name by passing config->id of -1.

[PATCH 04/25] nvmem: vf610-ocotp: Convert to use devm_nvmem_register()

[srinivas.kandagatla]

From: Andrey Smirnov <andrew.smirnov@gmail.com>

Drop all of the code related to .remove hook and make use of
devm_nvmem_register() instead.

[PATCH 22/25] nvmem: add i.MX7 support to snvs-lpgpr

[srinivas.kandagatla]

From: Andrey Yurovsky <yurovsky@gmail.com>

The i.MX7 family has similar SNVS hardware so make the snvs-lpgpr
support it along with the i.MX6 family. The register interface is the
same except for the number and offset of the general purpose registers.

[PATCH 23/25] nvmem: sunxi-sid: fix H3 SID controller support

[srinivas.kandagatla]

From: Icenowy Zheng <icenowy@aosc.io>

It seems that doing some operation will make the value pre-read on H3
SID controller wrong again, so all operation should be performed by
register.

Change the SID reading to use register only.

[PATCH 24/25] dt-bindings: nvmem: imx-ocotp: update the binding to reflect data cells

[srinivas.kandagatla]

From: Dong Aisheng <aisheng.dong@nxp.com>

imx-ocotp is implemented based on nvmem which can have data cells
as child node. Update the binding doc to reflect it to be more easily
understood by users.
