65 * omap242x_cpu_suspend() - Forces OMAP into deep sleep state by completing
66 * SDRC shutdown then ARM shutdown. Upon wake MPU is back on so just restore
67 * SDRC.
68 *
69 * Input:
70 * R0 : DLL ctrl value pre-Sleep
71 * R1 : Processor+Revision
72 * 2420: 0x21 = 242xES1, 0x26 = 242xES2.2
73 * 2430: 0x31 = 2430ES1, 0x32 = 2430ES2
74 *
75 * The if the DPLL is going to AutoIdle. It seems like the DPLL may be back on
76 * when we get called, but the DLL probably isn't. We will wait a bit more in
77 * case the DPLL isn't quite there yet. The code will wait on DLL for DDR even
78 * if in unlocked mode.
79 *
80 * For less than 242x-ES2.2 upon wake from a sleep mode where the external
81 * oscillator was stopped, a timing bug exists where a non-stabilized 12MHz
82 * clock can pass into the PRCM can cause problems at DSP and IVA.
83 * To work around this the code will switch to the 32kHz source prior to sleep.
84 * Post sleep we will shift back to using the DPLL. Apparently,
85 * CM_IDLEST_CLKGEN does not reflect the full clock change so you need to wait
86 * 3x12MHz + 3x32kHz clocks for a full switch.
87 *
88 * The DLL load value is not kept in RETENTION or OFF. It needs to be restored
89 * at wake
