GPIO driven I2C bus can be used for controlling the PMIC chip. The example of such configuration is Samsung Aquila board. This patch moves initialization code to subsys_initcall() to ensure that the i2c bus is available early so the regulators can be quickly probed and available for other devices on their probe() call. Such solution has been proposed by Mark Brown to fix the problem of the regulators not beeing available on the peripheral device probe(): http://lists.infradead.org/pipermail/linux-arm-kernel/2010-March/011971.html Cc: Mark Brown <broonie@opensource.wolfsonmicro.com> Reviewed-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Acked-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Jean Delvare <khali@linux-fr.org> |
