2013-01-19ARM: OMAP2: Fix missing omap2xxx_clkt_vps_late_init function callsJon Hunter2-0/+4
During the migration to the common clock framework, calls to the functions omap2xxx_clkt_vps_late_init() were not preserved for OMAP2420 and OMAP2430. This causes the variables "sys_ck_rate" and "curr_prcm_set" to be uninitialised on boot. On reboot, this causes the following error message to be displayed because the appropriate MPU clock frequency (derived from sys_ck_rate) cannot be found. "Could not set MPU rate to 4294MHz" Fix this by adding back calls to omap2xxx_clkt_vps_late_init() in the OMAP2420 and OMAP2430 clock initialisation code.

2013-01-04ARM: drivers: remove __dev* attributes.Greg Kroah-Hartman2-9/+9
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers.

git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.8-rc2/fixes Some OMAP PRCM and sparse fixes against v3.8-rc1. A basic set of test logs are available here: http://www.pwsan.com/omap/testlogs/prcm_fixes_b_3.8-rc/20130102120724/ The 3730 Beagle XM here has an intermittent failure mounting SD root, but the suspicion right now is that this is due to a failing SD card, rather than any change introduced by these patches. This second version includes a few changes requested by Tony Lindgren.
2013-01-02ARM: OMAP2/3: PRM: fix bogus OMAP2xxx powerstate return valuesPaul Walmsley3-28/+110
On OMAP2xxx chips, the register bitfields for the PM_PWSTCTRL_*.POWERSTATE and PM_PWSTST_*.LASTSTATEENTERED are different than those used on OMAP3/4. The order is reversed. So, for example, on OMAP2xxx, 0x0 indicates 'ON'; but on OMAP3/4, 0x0 indicates 'OFF'. Similarly, on OMAP2xxx, 0x3 indicates 'OFF', but on OMAP3/4, 0x3 indicates 'ON'. To fix this, we treat the OMAP3/4 values as the powerdomain API values, and create new low-level powerdomain functions for the OMAP2xxx chips which translate between the OMAP2xxx values and the OMAP3/4 values. Without this patch, the conversion of the OMAP2xxx PM code to the functional powerstate code results in a non-booting kernel. Signed-off-by: Paul Walmsley <paul@pwsan.com>
2013-01-02ARM: OMAP3: clock data: Add missing enable/disable for EMU clockJon Hunter1-0/+2
The ETM/ETB drivers for OMAP3, enable the emu_src_ck clock in order to access the ETM/ETB hardware. The emu_src_ck should enable the EMU clock domain so that the ETM/ETB hardware is accessible. However, currently when enabling the emu_src_ck the EMU clock domain is not being enabled and so the ETM/ETB drivers are failing. Add enable/disable clock functions to enable the EMU clock domain when enabling the emu_src_ck. Signed-off-by: Jon Hunter <jon-hunter@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>

2012-12-21ARM: OMAP2+: Trivial fix for IOMMU merge issueTony Lindgren1-2/+2
Commit 787314c35fbb ("Merge tag 'iommu-updates-v3.8' of git://git./linux/kernel/git/joro/iommu") did not account for the changed header location. The headers were made local to mach-omap2 as they are specific to omap2+ only, and we wanted to get most of the #include <plat/*.h> headers fixed up anyways for the ARM multiplatform support. We attempted to avoid this kind of merge conflict early on by setting up a minimal git branch shared by the arm-soc tree and the iommu tree, but looks like we still hit a merge issue there as the branches got merged as various topic branches.

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull IOMMU updates from Joerg Roedel: "A few new features this merge-window. The most important one is probably, that dma-debug now warns if a dma-handle is not checked with dma_mapping_error by the device driver. This requires minor changes to some architectures which make use of dma-debug. Most of these changes have the respective Acks by the Arch-Maintainers. Besides that there are updates to the AMD IOMMU driver for refactor the IOMMU-Groups support and to make sure it does not trigger a hardware erratum. The OMAP changes (for which I pulled in a branch from Tony Lindgren's tree) have a conflict in linux-next with the arm-soc tree. The conflict is in the file arch/arm/mach-omap2/clock44xx_data.c which is deleted in the arm-soc tree. It is safe to delete the file too so solve the conflict. Similar changes are done in the arm-soc tree in the common clock framework migration.

2012-12-15ARM: OMAP4: Fix EMU clock domain always onJon Hunter1-1/+2
Commit d043d87 (ARM: OMAP2+: clockdomain: bypass clockdomain handling when disabling unused clks) skips the decrementing of a clock-domains use count if the clocks use count is zero. However, for OMAP4 devices this is causing the EMU clock-domain to be stuck ON as the use count is not getting decremented correctly. The scenario that leads to this problem is described below ... omap_hwmod_setup_all --> _setup --> clkdm_hwmod_enable --> EMU clock domain usecount = 1 --> _enable_clocks --> clk_enable --> trace_clk_div_div usecount = 1 --> clkdm_hwmod_enable --> EMU clock domain usecount = 2 --> _idle --> _disable_clocks --> clk_disable --> trace_clk_div_div usecount = 0 --> clkdm_hwmod_disable --> skips decrement of EMU clock domain usecount because trace_clk_div_div is 0! --> EMU clock domain usecount = 2 --> clkdm_hwmod_disable --> EMU clock domain usecount = 1 Hence, due to the order that a clocks use count is decremented and the clock domain is disabled, it is possible that the clock domain can have a non-zero use count when the actual clock has a use count of 0. Therefore, we should only bypass the clock-domain handling when both the clock-domain and clock in the clock-domain have a use count of 0 and warn when the clock-domain has a zero use count and the clock has a non-zero use count.

2012-12-15ARM: OMAP4460: Workaround ABE DPLL failing to turn-onJon Hunter1-0/+22
With the latest mainline u-boot bootloader (v2012.10), timers (5-8) in the ABE power domain are failing to turn-on. The timers never come out of the disabled state when setting the module-mode field to enable. The problem was exposed when u-boot was updated to NOT configure and lock the ABE DPLL on start-up. If the ABE DPLL is configured and locked by u-boot the problem does not occur. However, if the ABE DPLL is in the idle low-power bypass state and we attempt to enable a timer in the ABE power domain, it remains stuck in the disabled state. It appears to be a problem the timer interface clock as this comes from the ABE DPLL. If we place the ABE DPLL in the MN-bypass state and not the idle low-power state, then this problem is not seen. This problem only appears to occur on OMAP4460 and not OMAP4430. Workaround this problem by locking the ABE DPLL for OMAP4460 in the kernel on boot. By locking the ABE DPLL, when clocks from the ABE DPLL are not being requested the DPLL will transition into a low-power stop mode.

2012-12-15ARM: OMAP4: Enhance support for DPLLs with 4X multiplierJon Hunter4-23/+99
On OMAP4 devices, the ABE DPLL has an internal 4X multiplier that can be enabled or disabled in addition to the standard configurable multiplier (M) for OMAP DPLLs. When configuring the ABE DPLL the 4X multiplier is accounted for by checking to see whether it is enabled or not. However, when calculating a new rate we only check to see if the rate can be achieved with the current setting for the 4X multiplier. Enhance the round_rate() function for such DPLLs to see if the rate can be achieved with the 4X multiplier if it cannot be achieved without the 4X multiplier. This change is necessary, because when using the 32kHz clock as the source clock for the ABE DPLL, the default DPLL frequency for the ABE DPLL cannot be achieved without enabling the 4X multiplier. When using the 32kHz clock as the source clock for the ABE DPLL and attempting to lock the DPLL to 98.304MHz (default frequency), it was found that the DPLL would fail to lock if the low-power mode for the DPLL was not enabled. From reviewing boot-loader settings that configure the ABE DPLL it was found that the low-power mode is enabled when using the 32kHz clock source, however, the documentation for OMAP does not state that this is a requirement. Therefore, introduce a new function for OMAP4 devices to see if low-power mode can be enabled when calculating a new rate to ensure the DPLL will lock. New variables for the last calculated 4X multiplier and low-power setting have been added to the dpll data structure as well as variables defining the bit mask for enabling these features via the DPLL's control_reg. It is possible that we could eliminate these bit masks from the dpll data structure as these bit masks are not unique to OMAP4, if it is preferred. The function omap3_noncore_program_dpll() has been updated to avoid passing the calculated values for the multiplier (M) and divider (N) as these are stored in the clk structure.

2012-12-15ARM: OMAP4: Add function table for non-M4X dpllsJon Hunter1-4/+13
Currently all OMAP4 non-core DPLLs use the same function table for configuring DPLLs. For these DPLLs, the function omap4_dpll_regm4xen_recalc() is used to recalculate the DPLL rate and the function omap4_dpll_regm4xen_round_rate() is used to calculate the closest rate to that requested. However, these omap4_dpll_regm4xen_xxx() functions are only applicable to the ABE DPLL and not the other non-core DPLLs. Therefore, add a new function table for non-core DPLLs that do not include the 4X-multiplier (M4X). Please note that using these omap4_dpll_regm4x_xxx() function works for the non-M4X DPLLs today because we only check to see if the 4X multiplier is enabled when calculating the rate. However, it is planned that the dpll functions will be enhanced to enable the 4X multiplier as necessary (in order to achieve the requested rate) and so calling these functions for non-M4X dplls will no longer work.

Commit "ARM: dts: OMAP4: Update timer addresses" updated the device-tree names of the OMAP4 timers 5-7 because the default address for the timers was changed from the L3 address to the MPU private address. When booting with device-tree, this introduces a regression when attempting to set the parent clock of timers 5-7 to the sys_clk_div_ck. Therefore, update the clock aliases for timer 5-7 to reflect the updated device-tree name for the timers.
