2013-01-21ASoC: sgtl5000: Fix maximum value for microphone gainT30_LinuxImageV2.0Alpha1_20130122Fabio Estevam
sgtl5000 microphone gain only has 2 bits of resolution, so maximum value is 3. From Eric Nelson: "We also found that for the microphones we have here (commodity PC boom mics) a default value of 2 for the gain gives the best results." So change the default microphone gain as well.

2013-01-21ASoC: sgtl5000: Enable VAG when DAC/ADC upZeng Zhaoming
As manual described, VAG is an internal voltage reference of DAC/ADC, So enabled it before DAC/ADC up. One more thing should care about is VAG fully ramped down requires 400ms, wait it to avoid pop.

2011-08-03ASoC: sgtl5000: fix cache handlingWolfram Sang
Cache handling in this driver is broken. The chip has 16-bit registers, yet the register numbers also increase by 2 per register, i.e. there are only even-numbered registers. The cache in this driver, though, simply increments register numbers, so it does need some mapping as seen in sgtl5000_restore_regs(), note the '>> 1': snd_soc_write(codec, SGTL5000_CHIP_LINREG_CTRL, cache[SGTL5000_CHIP_LINREG_CTRL >> 1]); That, of course, won't work with snd_soc_update_bits(). (Thus, we won't even notice the missing register 0x1c in the default regs which shifted all follwing registers to wrong values.) Noticed on the MX28EVK where enabling the regulators simply locked up the chip. Refactor the routines and use a properly sized default_regs array which matches the register layout of the underlying chip, i.e. create a truly flat cache. This also saves some code which should make up for the bigger array a little. When soc-core will somewhen have another cache type which handles a step size, this conversion will also ease the transition.
