Subject: [PATCH v2 0/5] thermal: imx: Add nvmem-cells binding on imx6sx

On imx6sx accessing OCOTP directly is wrong because the ocotp clock needs to be
enabled first. Fix this by adding a nvmem-cells binding and using it on imx6sx,
imx6ul and imx6ull.

The existing binding is kept around because it works fine on imx6qdl.

This was initially reported by Lothar Waßmann <LW@...O-electronics.de> in reply
to a patch adding imx6ul/ull support:

Changes since v1:
 * Move nvmem_cell_read_u32 to nvmem core (Shawn Guo, Srinivas Kandagatla)
 * Adjust binding description (Rob Herring)
 * Adjust formatting of thermal info cells (Shawn Guo)
 * Link: https://lkml.org/lkml/2017/7/6/426

Leonard Crestez (5):
  thermal: imx: Add nvmem-cells alternate binding for OCOTP access
  nvmem: core: Add nvmem_cell_read_u32
  thermal: imx: Add support for reading OCOTP through nvmem
  ARM: dts: imx6sx: Use nvmem-cells for tempmon
  ARM: dts: imx6ul: Add imx6ul-tempmon
