2009-10-06omap: iovmm: Add missing mutex_unlockDaniel Walker
I was using Coccinelle with the mutex_unlock semantic patch, and it unconvered this problem. It appears to be a valid missing unlock issue. This change should correct it by moving the unlock below the label. This patch is against the mainline kernel.

2009-10-05omap: Fix incorrect 730 vs 850 detectionTony Lindgren
Commit cd92204924fafbd5c7241dfd12ca3176d542e0c5 added support for omap850. However, the patch accidentally removed the wrong ifdef: # define cpu_is_omap730() 1 # endif #endif +#else +# if defined(CONFIG_ARCH_OMAP850) +# undef cpu_is_omap850 +# define cpu_is_omap850() 1 +# endif +#endif ... void omap2_check_revision(void); #endif /* defined(CONFIG_ARCH_OMAP2) || defined(CONFIG_ARCH_OMAP3) */ - -#endif Instead of removing removing the #endif at the end of the file, the #endif before #else should have been removed. But we cannot have multiple #else statements as pointed out by Alistair Buxton <a.j.buxton@gmail.com>. So the fix is to: - remove the non-multi-omap special handling, as we need to detect between omap730 and omap850 anyways. - add the missing #endif back to the end of the file Reported-by: Sanjeev Premi <premi@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2009-10-05OMAP3: PM: introduce a new powerdomain walk helperArtem Bityutskiy
The 'pwrdm_for_each()' function walks powerdomains with a spinlock locked, so the the callbacks cannot do anything which may sleep. This patch introduces a 'pwrdm_for_each_nolock()' helper which does the same, but without the spinlock locked. This fixes the following lockdep warning: [ 0.000000] WARNING: at kernel/lockdep.c:2460 lockdep_trace_alloc+0xac/0xec() [ 0.000000] Modules linked in: (unwind_backtrace+0x0/0xdc) from [<c0045464>] (warn_slowpath_common+0x48/0x60) (warn_slowpath_common+0x48/0x60) from [<c0067dd4>] (lockdep_trace_alloc+0xac/0xec) (lockdep_trace_alloc+0xac/0xec) from [<c009da14>] (kmem_cache_alloc+0x1c/0xd0) (kmem_cache_alloc+0x1c/0xd0) from [<c00b21d8>] (d_alloc+0x1c/0x1a4) (d_alloc+0x1c/0x1a4) from [<c00a887c>] (__lookup_hash+0xd8/0x118) (__lookup_hash+0xd8/0x118) from [<c00a9f20>] (lookup_one_len+0x84/0x94) (lookup_one_len+0x84/0x94) from [<c010d12c>] (debugfs_create_file+0x8c/0x20c) (debugfs_create_file+0x8c/0x20c) from [<c010d320>] (debugfs_create_dir+0x1c/0x20) (debugfs_create_dir+0x1c/0x20) from [<c000e8cc>] (pwrdms_setup+0x60/0x90) (pwrdms_setup+0x60/0x90) from [<c002e010>] (pwrdm_for_each+0x30/0x80) (pwrdm_for_each+0x30/0x80) from [<c000e79c>] (pm_dbg_init+0x7c/0x14c) (pm_dbg_init+0x7c/0x14c) from [<c00232b4>] (do_one_initcall+0x5c/0x1b8) (do_one_initcall+0x5c/0x1b8) from [<c00083f8>] (kernel_init+0x90/0x10c) (kernel_init+0x90/0x10c) from [<c00242c4>] (kernel_thread_exit+0x0/0x8) Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2009-09-24omap: Fix MMC gpio_wp for BeagleBoard C2 and aboveJarkko Nikula
Earlier BeagleBoards were using pad AH8 muxed to GPIO29 for MMC write-protect. However, this signal has been changed to pad AG9 in board revision C2. Fix this by adding mux configuration for pad AG9, runtime check for board revisions and set the gpio number and pad muxing accordingly.

2009-09-03OMAP2/3/4 core: create omap_device layerPaul Walmsley
The omap_device code provides a mapping of omap_hwmod structures into the platform_device system, and includes some details on external (board-level) integration. This allows drivers to enable, idle, and shutdown on-chip device resources, including clocks, regulators, etc. The resources enabled and idled are dependent on the device's maximum wakeup latency constraint (if present). At the moment, omap_device functions are intended to be called from platform_data function pointers. Ideally in the future these functions will be called from either subarchitecture-specific platform_data activate, deactivate functions, or via an custom bus/device type for OMAP.

2009-09-03OMAP2/3/4: create omap_hwmod layerPaul Walmsley
OMAP SoCs can be considered a collection of hardware IP blocks connected by various interconnects. The bus topology and device integration data is somewhat more complex than platform_device can encode. This patch creates code and structures to manage information about OMAP on-chip devices ("hardware modules") and their integration to the rest of the chip. Hardware module data is intended to be generated dynamically from the TI hardware database for the OMAP4 chips and beyond, easing Linux support for new chip variants. This code currently: - resets and configures all hardware modules upon startup, reducing bootloader dependencies; - provides hooks for Linux driver model code to enable, idle, and shutdown hardware modules (forthcoming patch); - waits for hardware modules to leave idle once their clocks are enabled and OCP_SYSCONFIG bits are set appropriately. - provides a means to pass arbitrary IP block configuration data (e.g., FIFO size) to the device driver (via the dev_attr void pointer) In the future this code is intended to: - estimate interconnect bandwidth and latency characteristics to ensure constraints are satisfied during DVFS - provide *GRPSEL bit data to the powerdomain code - handle pin/ball muxing for devices - generate IO mapping information dynamically - supply device firewall configuration data - provide hardware module data to other on-chip coprocessor software - allow the removal of the "disable unused clocks" code in the OMAP2/3 clock code This patch represents a collaborative effort involving many people from TI, Nokia, and the Linux-OMAP community.

2009-09-03OMAP2/3 board-*.c files: read bootloader configuration earlierPaul Walmsley
Most board-*.c files read configuration data from the bootloader in their .init_machine() function. This needs to happen earlier, at some point before omap2_init_common_hw() is called. This is because a future patch will use the bootloader serial console port information to enable the UART clocks earlier, immediately after omap2_clk_init(). This is in turn necessary since otherwise clock tree usecounts on clocks like dpll4_m2x2_ck will be bogus, which can cause the currently-active console UART clock to be disabled during boot.

2009-09-03OMAP2/3 PM: create the OMAP PM interface and add a default OMAP PM no-op layerPaul Walmsley
The interface provides device drivers, CPUFreq, and DSPBridge with a means of controlling OMAP power management parameters that are not yet supported by the Linux PM PMQoS interface. Copious documentation is in the patch in Documentation/arm/OMAP/omap_pm and the interface header file, arch/arm/plat-omap/include/mach/omap-pm.h. Thanks to Rajendra Nayak <rnayak@ti.com> for adding CORE (VDD2) OPP support and moving the OPP table initialization earlier in the event that the clock code needs them.

2009-09-02OMAP: PM: Add pm-debug countersPeter 'p2' De Schrijver
This patch provides the debugfs entries and a function which will be called by the PM code to register the time spent per domain per state. Also some new fields are added to the powerdomain struct to keep the time information. NOTE: As of v2.6.29, using getnstimeofday() after drivers are suspended is no longer safe since the timekeeping subsystem is also suspended as part of the suspend process. Instead use sched_clock() which on OMAP returns the 32k SYNC timer in nanoseconds. Also, do not print out status for meta powerdomains (dpll*) Signed-off-by: Peter 'p2' De Schrijver <peter.de-schrijver@nokia.com> Signed-off-by: Tero Kristo <tero.kristo@nokia.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

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.
