I started to add the H3 into the sun4i-i2s, but I am blocked with regmap. Many H3 registers are common with the A10, but some of them have more or less fields, the fields may be at different offsets. And, finally, some registers are completely different. This would not raise any problem, except with regmap which is really painful. As I may understood, regmap is used to simplify suspend/resume, but, is it useful to save the I2S register on suspend? Practically, I am streaming some tune on my device. I suspend it for any reason. The next morning, I resume it. Are you sure I want to continue to hear the end of the tune? I better think that streaming should be simply stopped on suspend. Then, there is no need to save the playing registers, and, here I am, there is no need to use regmap. May I go this way? -- Ken ar c'hentañ | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/ -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
