2013-07-01regulator: max77693: Remove NULL test for rmatch[i].init_dataAxel Lin1-3/+1
The implementation in of_regulator_match() already ensures match->init_data is not NULL for all matched cases if the return value of of_regulator_match() > 0. Thus remove NULL test for rmatch[i].init_data. This patch also fixes the condition for loop iteration. The for loop should iterate "matched" times rather than ARRAY_SIZE(regulators) because we only allocate "matched" number of entries for rdata. Though in most cases, "matched" == ARRAY_SIZE(regulators).

2013-06-24regulator: max8973: initial DT supportGuennadi Liakhovetski1-12/+25
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>

2013-06-21regulators: max8973: fix multiple instance supportGuennadi Liakhovetski1-5/+7
Currently the max8973 regulator driver uses a single static struct of regulator operations for all chip instances, but can overwrite some of its members depending on configuration. 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.

Well in order to do that we need to provide this call-back, where we check that the value is sane and return without error.
