regulator: max8973: initial DT support 2013-06-24T14:22:26+00:00 Guennadi Liakhovetski g.liakhovetski@gmx.de 2013-06-24T10:50:16+00:00 42dc30231ba35939213c33378c17cb81c31b0a37 This patch adds primitive DT support to the max8973 regulator driver. None of the configuration parameters, supported in the platform data are yet available in DT, therefore no configuration is performed if booting with no platform data. This means, that DT instantiation can only be used on boards, where no run-time configuration of the chip is required. In such cases the driver can be used to scale its output voltage. In the future support for configuration parameters should be added. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski+renesas@gmail.com> Signed-off-by: Mark Brown <broonie@linaro.org>

This will affect all other MAX8973 instances on the system. This patch fixes this bug by allocating a separate copy of the struct for each chip instance.

As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers.
