The ultimate aim is to provide the dts file but some updates are needed to the simple-card machine driver. Patches are needed to simple-card to enable support for setting the component sysclks and plls. The codec sysclks and plls cannot be placed under the clock framwork because they are I2C/SPI-connected peripherals and access to the registers would cause a nested get of the I2C/SPI bus clock. The clock framework does not support this and it would result in a deadlock.
