* OMAP2/3: Add omap_type() for determining GP/EMU/HSKevin Hilman2009-06-23
| | | | | | | | | | | | | | | The omap_type() function is added and returns the DEVICETYPE field of the CONTROL_STATUS register. The result can be used for conditional code based on whether device is GP (general purpose), EMU or HS (high security). Also move the type defines so omap1 code compile does not require ifdefs for sections using these defines. This code is needed for the following fix to set the SRAM size correctly for HS omaps. Also at least PM and watchdog code will need this function. Signed-off-by: Kevin Hilman <khilman@ti.deeprootsystems.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

| * OMAP3 clock/SDRC: program SDRC_MR register during SDRC clock changePaul Walmsley2009-06-19
| | | | | | | | | | | | | | | | | | Program the SDRC_MR_0 register as well during SDRC clock changes. This register allows selection of the memory CAS latency. Some SDRAM chips, such as the Qimonda HYB18M512160AF6, have a lower CAS latency at lower clock rates. Signed-off-by: Paul Walmsley <paul@pwsan.com>
| * OMAP3 clock: add a short delay when lowering CORE clk ratePaul Walmsley2009-06-19
| | | | | | | | | | | | | | | | | | | | | | | | | | When changing the SDRAM clock from 166MHz to 83MHz via the CORE DPLL M2 divider, add a short delay before returning to SDRAM to allow the SDRC time to stabilize. Without this delay, the system is prone to random panics upon re-entering SDRAM. This time delay varies based on MPU frequency. At 500MHz MPU frequency at room temperature, 64 loops seems to work okay; so add another 32 loops for environmental and process variation. Signed-off-by: Paul Walmsley <paul@pwsan.com>

| * | OMAP3: PM: UART: disable clocks when idle and off-mode supportKevin Hilman2009-05-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows the UART clocks to be disabled when the OMAP UARTs are inactive, thus permitting the chip to hit retention in idle. After the expiration of an activity timer, each UART is allowed to disable its clocks so the system can enter retention. The activity timer is (re)activated on any UART interrupt, UART wake event or any IO pad wakeup. The actual disable of the UART clocks is done in the 'prepare_idle' hook called from the OMAP idle loop. While the activity timer is active, the smart-idle mode of the UART is also disabled. This is due to a "feature" of the UART module that after a UART wakeup, the smart-idle mode may be entered before the UART has communicated the interrupt, or upon TX, an idle mode may be entered before the TX FIFOs are emptied. Upon suspend, the 'prepare_suspend' hook cancels any pending activity timers and allows the clocks to be disabled immediately. In addition, upon disabling clocks the UART state is saved in case of an off-mode transition while clocks are off. Special thanks to Tero Kristo for the initial ideas and first versions of UART idle support, and to Jouni Hogander for extra testing and bugfixes.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the 34xx TRM Rev. K section 11.2.4.4.11.1 "Purpose of the DLL/CDL Module," the SDRC delay-locked-loop can be locked at any SDRC clock frequency from 83MHz to 166MHz. CDP code unconditionally unlocked the DLL whenever shifting to a lower SDRC speed, but this seems unnecessary and error-prone, as the DLL is no longer able to compensate for process, voltage, and temperature variations. Instead, only unlock the DLL when the SDRC clock rate would be less than 83MHz. Signed-off-by: Paul Walmsley <paul@pwsan.com>

| * | OMAP2/3 GPTIMER: allow system tick GPTIMER to be changed in board-*.c filesPaul Walmsley2009-04-23
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a function omap2_gp_clockevent_set_gptimer() for board-*.c files to use in .init_irq functions to configure the system tick GPTIMER. Practical choices at this point are GPTIMER1 or GPTIMER12. Both of these timers are in the WKUP powerdomain, and so are unaffected by chip power management. GPTIMER1 can use sys_clk as a source, for applications where a high-resolution timer is more important than power management. GPTIMER12 has the special property that it has the secure 32kHz oscillator as its source clock, which may be less prone to glitches than the off-chip 32kHz oscillator. But on HS devices, it may not be available for Linux use. It appears that most boards are fine with GPTIMER1, but BeagleBoard should use GPTIMER12 when using a 32KiHz timer source, due to hardware bugs in revisions B4 and below. Modify board-omap3beagle.c to use GPTIMER12. This patch originally used a Kbuild config option to select the GPTIMER, but was changed to allow this to be specified in board-*.c files, per Tony's request. Kalle Vallo <kalle.valo@nokia.com> found a bug in an earlier version of this patch - thanks Kalle. Tested on Beagle rev B4 ES2.1, with and without CONFIG_OMAP_32K_TIMER, and 3430SDP.
