I always seem > to have trouble tracking this stuff down. The clock stuff isn't in the kernel yet, so there's no commit to point to. The commit I asked you to create would update the bindings to define which clocks the I2C node needs, and would then go into U-Boot and the kernel. As a reference though, look at the kernel I2C driver and see that it performs two clk_get() calls, and then look into tegra2_clocks.c to see the two clocks it matches. -- nvpublic -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
