[U-Boot] [PATCH v4 0/5] add i.MX6 thermal sensor driver

[Nitin Garg]

This patch set adds i.MX6 thermal sensor driver
and enables it for mx6sabre boards. Also adds
various anadig bit definitions as required for
upcoming drivers.

Changes in v4:
-Added imx6 thermal sensor as a driver
-Renamed the config define to be more meaningful
-Move the clock code to clock.c
-Reusing ocotp driver for reading fuse
-Fix check for calibration fuse not programmed
-Aligned the slope computation with kernel
-Added Anadig register defines as seperate commit

Changes in v3:
-adds the mx6 temperature support
-adds the mx6 temperature support to mx6sabresd board.

Changes in v2:
-run checkpatch and fix reported issues

Nitin Garg (5):
  mx6: crm_regs: Add bit definitions for anadig registers
  mx6: clock: Add api to enable pll3
  mx6: thermal: Add i.MX6 CPU thermal sensor support
  mx6: thermal: Check cpu temperature via thermal sensor
  mx6: thermal: Enable thermal sensor for mx6 sabre boards.

[U-Boot] [PATCH v4 5/5] mx6: thermal: Enable thermal sensor for mx6 sabre boards.

[Nitin Garg]

Add CONFIG_IMX6_THERMAL to mx6sabre_common.h file. Since
thermal driver depends on ocotp, make sure to enable
CONFIG_MXC_OCOTP when CONFIG_IMX6_THERMAL is slected.

Signed-off-by: Nitin Garg <nitin.garg@freescale.com>
---

Changes in v4:
-Added imx6 thermal sensor as a driver
-Renamed the config define to be more meaningful
-Move the clock code to clock.c
-Reusing ocotp driver for reading fuse
-Fix check for calibration fuse not programmed
-Aligned the slope computation with kernel
-Added Anadig register defines as seperate commit

Changes in v3:
-adds the mx6 temperature support
-adds the mx6 temperature support to mx6sabresd board.

Changes in v2:
-run checkpatch and fix reported issues

This is a legal issue. I guess some changes like this one have already
flown into mainline, but I am quite unsure that this is legally correct.
Originally, when the file was introduced, it had Freescale's Copyright -
fine.

Of course, this header file was changed several times, and not only by
Freescale or Freescale's employers. Is it then correct to update the
copyright now, extending the datum ? I doubt this is ok.

Thanks for clarification,
Stefano Babic

Shall I remove it and resend? Or shall I change it to 2011,2014?
Pls suggest.
