- Support PLL for Higher Frequencies 80,160,240 MHz - Support XTAL Frequencies 26MHz, 40MHz - Clock Driver can't be disabled, because all of the other drivers will depend on it to get their operating Frequency based on chosen clock source (XTAL/PLL). - Add needed references to BBPLL i2c bus ROM functions. - Add `rtc` node to Device Tree. - Since All Peripherals Frequency is depending on CPU_CLK Source, `clock-source` property added to CPU node Signed-off-by: Mohamed ElShahawi <ExtremeGTX@hotmail.com>
