2009-09-03OMAP3 clock: remove superfluous calls to omap2_init_clk_clkdmPaul Walmsley
omap2_init_clk_clkdm() is called as part of the chip architecture-specific initialization code, so calling it again from the struct clk init pointer just wastes cycles. Signed-off-by: Paul Walmsley <paul@pwsan.com>
2009-09-03OMAP clock: associate MPU clocks with the mpu_clkdmPaul Walmsley
All MPU-related clocks should be in the mpu_clkdm. This is needed for the upcoming omap_hwmod patches, which needs to know the clockdomain that arm_fck is in. Signed-off-by: Paul Walmsley <paul@pwsan.com>

2009-09-03OMAP: powerdomain: Fix overflow when doing powerdomain deps lookups.Paul Walmsley
At the end of the list pd is a pointer to a NULL struct, so checking if the address == NULL doesn't help here. In fact the original code will just keep running past the struct to read who knows what in memory. This case manifests itself when from clkdms_setup() when enabling auto idle for a clock domain and the clockdomain usecount is greater than 0. When _clkdm_add_autodeps() tries to add the a dependency that does not exist in the powerdomain->wkdep_srcs array the for loop will run past the wkdep_srcs array. Currently in linux-omap you won't hit this because the not found case is never executed, unless you start modifying powerdomains and their wakeup/sleep deps.

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.

This patch causes the OMAP uarts to honor the sysfs power/wakeup file for IOPAD wakeups. Before the OMAP was always woken up from off mode on a rs232 signal change. This patch also creates a different platform device for each serial port so that the wakeup properties can be control per port. By default, IOPAD wakeups are enabled for each UART. To disable, # echo disabled > /sys/devices/platform/serial8250.0/power/wakeup Where serial8250.0 can be replaced by .1, or .2 to control the other ports.

2009-08-05OMAP3: Fixed crash bug with serial + suspendTero Kristo
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.

2009-07-24OMAP3 clock: correct module IDLEST bits: SSI; DSS; USBHOST; HSOTGUSBPaul Walmsley
Fix two bugs in the OMAP3 clock tree pertaining to the SSI, DSS, USBHOST, and HSOTGUSB devices. These devices are both interconnect initiators and targets. Without this patch, clk_enable()s on clocks for these modules can be very high latency (potentially up to ~200 milliseconds) and message such as the following are generated: Clock usbhost_48m_fck didn't enable in 100000 tries Two bugs are fixed by this patch. First, OMAP hardware only supports target CM_IDLEST register bits on ES2+ chips and beyond. ES1 chips should not wait for these clocks to enable. So, split the appropriate clocks into ES1 and ES2+ variants, so that kernels running on ES1 devices won't try to wait. Second, the current heuristic in omap2_clk_dflt_find_idlest() will fail for these clocks. It assumes that the CM_IDLEST bit to wait upon is the same as the CM_*CLKEN bit, which is false[1]. Fix by implementing custom clkops .find_idlest function pointers for the appropriate clocks that return the correct slave IDLEST bit shift. This was originally fixed in the linux-omap kernel during 2.6.29 in a slightly different manner[2][3]. In the medium-term future, all of the module IDLEST code will eventually be moved to the omap_hwmod code.

2009-07-24OMAP2/3 clock: split, rename omap2_wait_clock_ready()Paul Walmsley
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.
