2013-09-11ASoC: mc13783: add spi errata fixSteffen Trumtrar1-0/+4
The MC13783 Chip Errata, Rev. 4 says, that depending on SPI clock and main audio clock speed, the Audio Codec or Stereo DAC do sometimes not start when programmed to do so. This is due to an internal clock timing issue related to the loading of the SPI bits into the audio block. On an i.MX27 based system, this issue lead to switched audio channels under certain circumstances: RTC + Touch + Audio are used and loaded at startup. The mentioned workaround of writing registers 40 and 41 two times is implemented here.

CONFIG_HOTPLUG is going away as an option. As result the __dev* markings will be going away. Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit. Signed-off-by: Bill Pemberton <wfp5p@virginia.edu> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
