Hans de Goede	41751b033a	mfd: axp20x-i2c: Add i2c-ids to fix module auto-loading ... The i2c subsys does not load modules by compatible, only by i2c-id, with e.g. a modalias of: "i2c:axp209". Populate the axp20x_i2c_id[] table with supported ids, so that module auto-loading will work.

Chen-Yu Tsai	4fd4115142	mfd: axp20x: Split the driver into core and i2c bits ... The axp20x driver assumes the device is i2c based. This is not the case with later chips, which use a proprietary 2 wire serial bus by Allwinner called "Reduced Serial Bus". This patch follows the example of mfd/wm831x and splits it into an interface independent core, and an i2c specific glue layer. MFD_AXP20X and the new MFD_AXP20X_I2C are changed to tristate symbols, allowing the driver to be built as modules. Whitespace and other style errors in the moved i2c specific code have been fixed. Included but unused header files are removed as well. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>	2016-02-12 08:53:03 +00:00
