This is more kernel related than U-Boot, but I'm hoping you guys can help me out. I've been stuck on this for some days now with no response in the Freescale forum.
We ported our custom imx51 board from Linux 2.6 to Linux 3.14 (also u-boot 2009 -> 2014). In old kernel we set the ipu_di_clk parent to tve_clk in arch/arm/mach-mx5/clk.c. I'm having a heck of a time trying to figure out where or how to do that in new kernel. Can this be done in the dts or must it be done kernel code? I tried a few things in the dts and tried to set the IPU parent in the imx51.dtsi to TVE, but no cigar. I tried reading through ipu-di.c and ipu-common.c I tried different clock parent setups in clk-imx51-imx53.c. I checked the CCM registers and the relevant ones seem the same between both kernels. I'm sure I'm missing something or doing something wrong. Any help would be appreciated. -- View this message in context: http://u-boot.10912.n7.nabble.com/How-to-set-IPU-parent-clock-to-TVE-tp230361.html Sent from the U-Boot mailing list archive at Nabble.com. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
