28 * Clock types that we can use as a source. The Tegra210 has muxes for the
29 * peripheral clocks, and in most cases there are four options for the clock
30 * source. This gives us a clock 'type' and exploits what commonality exists
31 * in the device.
32 *
33 * Letters are obvious, except for T which means CLK_M, and S which means the
34 * clock derived from 32KHz. Beware that CLK_M (also called OSC in the
35 * datasheet) and PLL_M are different things. The former is the basic
36 * clock supplied to the SOC from an external oscillator. The latter is the
37 * memory clock PLL.
38 *
39 * See definitions in clock_id in the header file.
