DM355 PLL register write problem

Hi Steve, Thank you. I found the problem. Problem was with the order of the parameter that I was passing to davinci_writel() function. It takes davinci_writel(value, address) and I was passing it davinci_writel(address, value). After I changed the order of the parameter everything worked fine.
