It is possible for GPIO IRQ lines configured with falling edge triggering only to get IRQs at the rising edge upon the exit of offmode. And vice versa.

OMAP tags are deprecrated so drop them. Drop UART config data which decides which UARTs to enable during boot. This is no longer necessary since serial core code disables clocks after inactivity. Background: with new UART idle code, all on-chip UARTs are idled using a configurable inactivity timer (default 5 seconds.) After the inactivity timer, UART clocks are disabled automatically.

It was possible for an unhandled interrupt to occur if there was incoming serial traffic during wakeup from suspend. This was caused by the code in arch-arm/mach-omap2/serial.c keeping interrupt enabled all the time, but not acking its interrupts. Applies on top of PM branch. Use the PM begin/end hooks to ensure that the "serial idle" interrupts are disabled during the suspend path. Also, since begin/end hooks are now used, use the suspend_state that is passed in the begin hook instead of the enter hook as per the platform_suspend_ops docs.

Some OMAP2/3 hardware modules have CM_IDLEST attributes that are not handled by the current omap2_wait_clock_ready() code. In preparation for patches that fix the unusual devices, rename the function omap2_wait_clock_ready() to omap2_wait_module_ready() and split it into three parts: 1. A clkops-specific companion clock return function (by default, omap2_clk_dflt_find_companion()) 2. A clkops-specific CM_IDLEST register address and bit shift return function (by default, omap2_clk_dflt_find_idlest()) 3. Code to wait for the CM to indicate that the module is ready (omap2_cm_wait_idlest()) Clocks can now specify their own custom find_companion() and find_idlest() functions; used in subsequent patches.

This patches ensures the MUX settings are correct for the SDRC CKE signals to SDRAM. This allows the self-refresh to work when 2 chip-selects are in use. A warning is thrown away in case the initial muxing is incorrect, in order to track faulty or old-dated bootloaders. Note: The CONFIG_OMAP_MUX and CONFIG_OMAP_MUX_WARNINGS options must be enabled for the mux code to have effect.

Some OMAP3 boards (Beagle Cx, Overo, RX51, Pandora) have 2 SDRAM parts connected to the SDRC. This patch adds the following: - add a new argument of type omap_sdrc_params struct* to omap2_init_common_hw and omap2_sdrc_init for the 2nd CS params - adapted the OMAP boards files to the new prototype of omap2_init_common_hw - add the SDRC 2nd CS registers offsets defines - adapt the sram sleep code to configure the SDRC for the 2nd CS Note: If the 2nd param to omap2_init_common_hw is NULL, then the parameters are not programmed into the SDRC CS1 registers Tested on 3430 SDP and Beagleboard rev C2 and B5, with suspend/resume and frequency changes (cpufreq).

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.

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: NPaul Walmsley <paul@pwsan.com>
