2021-03-10ASoC: cs42l42: Wait for PLL to lock before switching to itRichard Fitzgerald1-1/+11
The PLL should have locked before using it to supply MCLK.

2021-03-10ASoC: cs42l42: Only start PLL if it is neededRichard Fitzgerald1-2/+3
The PLL is only needed for sclk < 11289600 Hz and cs42l42_pll_config() will not configure it for higher rates. So it must only be enabled when it is needed.

2021-03-10ASoC: cs42l42: Wait at least 150us after writing SCLK_PRESENTRichard Fitzgerald1-5/+22
There must be a delay of at least 150us after writing SCLK_PRESENT before issuing another I2C write. This is done using struct reg_sequence because it can specify a delay after the write and the whole sequence is written atomically.
