In a previous commit the en_core_tk_irqen flag has been added but we missed the cpuidle_wrap_enter which was doing the job to measure the time for the 'omap3_enter_idle' function. Actually, I don't see any reason to use this wrapper in the code. In the better case, the time computation is not correctly done because of the different operations done in omap3_enter_idle_bm which were not taken into account before the en_core_tk_irqen flag was set. As the time is reflected for the state overridden by the omap3_enter_idle_bm, using the wrapper is pointless now, so removing it.

Commit 92702df3570e ("ARM: OMAP4: PM: fix PM regression introduced by recent clock cleanup") makes the 'ocp2scp_usb_phy_phy_48m' as optional functional clock causing regression in MUSB. But this 48MHz clock is a mandatory clock for usb phy attached to ocp2scp and hence made as the main clock for ocp2scp.

2013-04-10cpufreq: OMAP: instantiate omap-cpufreq as a platform_driverNishanth Menon1-0/+9
As multi-platform build is being adopted by more and more ARM platforms, initcall function should be used very carefully. For example, when CONFIG_ARM_OMAP2PLUS_CPUFREQ is built in the kernel, omap_cpufreq_init() will be called on all the platforms to initialize omap-cpufreq driver. Further, on OMAP, we now use Soc generic cpufreq-cpu0 driver using device tree entries. To allow cpufreq-cpu0 and omap-cpufreq drivers to co-exist for OMAP in a single image, we need to ensure the following: 1. With device tree boot, we use cpufreq-cpu0 2. With non device tree boot, we use omap-cpufreq In the case of (1), we will have cpu OPPs and regulator registered as part of the device tree nodes, to ensure that omap-cpufreq and cpufreq-cpu0 don't conflict in managing the frequency of the same CPU, we should not permit omap-cpufreq to be probed. In the case of (2), we will not have the cpufreq-cpu0 device, hence only omap-cpufreq will be active. To eliminate this undesired these effects, we change omap-cpufreq driver to have it instantiated as a platform_driver and register "omap-cpufreq" device only when booted without device tree nodes on OMAP platforms. This allows the following: a) Will only run on platforms that create the platform_device "omap-cpufreq". b) Since the platform_device is registered only when device tree nodes are *not* populated, omap-cpufreq driver does not conflict with the usage of cpufreq-cpu0 driver which is used on OMAP platforms when device tree nodes are present.

2013-04-09ARM: OMAP4+: CPUidle: Deprecate use of omap4_mpuss_read_prev_context_state()Santosh Shilimkar3-20/+2
Current OMAP4 CPUIdle driver is using omap4_mpuss_read_prev_context_state() to check whether the MPU cluster lost context or not before calling cpu_cluster_pm_exit(). This was initially done an optimization for corner cases, where if the cluster low power entry fails for some reason, the cluster context restore gets skipped. However, since reading the previous context is expensive (involving slow accesses to the PRCM), it's better to avoid it and simply check the target cluster state instead. Moving forward, OMAP CPUidle drivers needs to be moved to drivers/idle/* once the PRM/CM code gets moved to drivers. This patch also reduces one dependency with platform code for idle driver movement.

2013-03-27ARM: OMAP: clocks: Delay clk inits atleast until slab is initializedRajendra Nayak3-6/+19
clk inits on OMAP happen quite early, even before slab is available. The dependency comes from the fact that the timer init code starts to use clocks and hwmod and we need clocks to be initialized by then. There are various problems doing clk inits this early, one is, not being able to do dynamic clk registrations and hence the dependency on clk-private.h. The other is, inability to debug early kernel crashes without enabling DEBUG_LL and earlyprintk. Doing early clk init also exposed another instance of a kernel panic due to a BUG() when CONFIG_DEBUG_SLAB is enabled.

It was a know issue, that slab allocations would fail when common clock core tries to cache parent pointers for mux clocks on OMAP, and hence a patch 'clk: Allow late cache allocation for clk->parents, commit 7975059d' was added to work this problem around. A BUG() within kmalloc() with CONFIG_DEBUG_SLAB enabled was completely overlooked causing this regression. More details on the issue reported can be found here, http://www.mail-archive.com/linux-omap@vger.kernel.org/msg85932.html With all these issues around clk inits happening way too early, it makes sense to at least move them to a point where dynamic memory allocations are possible. So move them to a point just before the timer code starts using clocks and hwmod. This should at least pave way for clk inits on OMAP moving to dynamic clock registrations instead of using the static macros defined in clk-private.h. The issue with kernel panic while CONFIG_DEBUG_SLAB is enabled was reported by Piotr Haber and Tony Lindgren and this patch fixes the reported issue as well.

2013-03-13ARM: OMAP4: PM: fix PM regression introduced by recent clock cleanupPaul Walmsley2-0/+11
Commit 17b7e7d33530e2bbd3bdc90f4db09b91cfdde2bb ("ARM: OMAP4: clock/hwmod data: start to remove some IP block control "clocks"") introduced a regression preventing the L3INIT clockdomain of OMAP4 systems from entering idle. This in turn prevented these systems from entering full chip clock-stop. The regression was caused by the incorrect removal of a so-called "optional functional clock" from the OMAP4 clock data. This wasn't caught for two reasons. First, I missed the retention entry failure in the branch test logs: http://www.pwsan.com/omap/testlogs/cleanup_a_3.9/20130126014242/pm/4460pandaes/4460pandaes_log.txt Second, the integration data for the OCP2SCP PHY IP block, added by commit 0c6688753f9912c6a7013549ec31c8844020bbc1 ("ARM: OMAP4: hwmod data: add remaining USB-related IP blocks"), should have associated this clock with the IP block, but did not.

2013-03-13ARM: OMAP3: hwmod data: keep MIDLEMODE in force-standby for musbGrazvydas Ignotas3-5/+18
For some unknown reason, allowing hwmod to control MIDLEMODE causes core_pwrdm to not hit idle states for musb in DM3730 at least. I've verified that setting any MIDLEMODE value other than "force standby" before enabling the device causes subsequent suspend attempts to fail with core_pwrdm not entering idle states, even if the driver is unloaded and "force standby" is restored before suspend attempt. To recover from this, soft reset can be used, but that's not suitable solution for suspend. Keeping the register set at force standby (reset value) makes it work and device still functions properly, as musb has driver-controlled OTG_FORCESTDBY register that controls MSTANDBY signal. Note that TI PSP kernels also have similar workarounds. This patch also fixes HWMOD_SWSUP_MSTANDBY documentation to match the actual flag name.

Some versions of the u-boot bootloader do not lock the USB DPLL and when the USB DPLL is not locked, then it is observed that the L3INIT power domain does not transition to retention state during kernel suspend on OMAP4 devices.

2013-03-04ARM: OMAP2+: mux: correct wrong error messagesRuslan Bilovol1-2/+2
This is needed because the omap_mux_get_by_name() function calls the _omap_mux_get_by_name subfunction for each mux partition until needed mux is not found. As a result, we get messages like "Could not find signal XXX" for each partition where this mux name does not exist. This patch fixes wrong error message in the _omap_mux_get_by_name() function moving it to the omap_mux_get_by_name() one and as result reduces noise in the kernel log.

Commit 6797b4fe (ARM: OMAP2+: Prevent potential crash if GPMC probe fails) added code to ensure that GPMC chip-selects could not be requested until the device probe was successful. The chip-selects should have been unreserved at the end of the probe function, but the code to unreserve them appears to have ended up in the gpmc_calc_timings() function and hence, this is causing problems requesting chip-selects. Fix this merge error by unreserving the chip-selects at the end of the probe, but before we call the gpmc child probe functions (for device-tree) which request a chip-select.

Pull networking update from David Miller: 1) Checkpoint/restarted TCP sockets now can properly propagate the TCP timestamp offset. From Andrey Vagin. 2) VMWARE VM VSOCK layer, from Andy King. 3) Much improved support for virtual functions and SR-IOV in bnx2x, from Ariel ELior. 4) All protocols on ipv4 and ipv6 are now network namespace aware, and all the compatability checks for initial-namespace-only protocols is removed. Thanks to Tom Parkin for helping deal with the last major holdout, L2TP. 5) IPV6 support in netpoll and network namespace support in pktgen, from Cong Wang. 6) Multiple Registration Protocol (MRP) and Multiple VLAN Registration Protocol (MVRP) support, from David Ward. 7) Compute packet lengths more accurately in the packet scheduler, from Eric Dumazet. 8) Use per-task page fragment allocator in skb_append_datato_frags(), also from Eric Dumazet. 9) Add support for connection tracking labels in netfilter, from Florian Westphal. 10) Fix default multicast group joining on ipv6, and add anti-spoofing checks to 6to4 and 6rd. From Hannes Frederic Sowa. 11) Make ipv4/ipv6 fragmentation memory limits more reasonable in modern times, rearrange inet frag datastructures for better cacheline locality, and move more operations outside of locking. From Jesper Dangaard Brouer. 12) Instead of strict master <--> slave relationships, allow arbitrary scenerios with "upper device lists". From Jiri Pirko. 13) Improve rate limiting accuracy in TBF and act_police, also from Jiri Pirko. 14) Add a BPF filter netfilter match target, from Willem de Bruijn. 15) Orphan and delete a bunch of pre-historic networking drivers from Paul Gortmaker. 16) Add TSO support for GRE tunnels, from Pravin B SHelar. Although this still needs some minor bug fixing before it's %100 correct in all cases. 17) Handle unresolved IPSEC states like ARP, with a resolution packet queue. From Steffen Klassert. 18) Remove TCP Appropriate Byte Count support (ABC), from Stephen Hemminger. This was long overdue. 19) Support SO_REUSEPORT, from Tom Herbert. 20) Allow locking a socket BPF filter, so that it cannot change after a process drops capabilities. 21) Add VLAN filtering to bridge, from Vlad Yasevich. 22) Bring ipv6 on-par with ipv4 and do not cache neighbour entries in the ipv6 routes, from YOSHIFUJI Hideaki. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1538 commits) ipv6: fix race condition regarding dst->expires and dst->from. net: fix a wrong assignment in skb_split() ip_gre: remove an extra dst_release() ppp: set qdisc_tx_busylock to avoid LOCKDEP splat atl1c: restore buffer state net: fix a build failure when !CONFIG_PROC_FS net: ipv4: fix waring -Wunused-variable net: proc: fix build failed when procfs is not configured Revert "xen: netback: remove redundant xenvif_put" net: move procfs code to net/core/net-procfs.c qmi_wwan, cdc-ether: add ADU960S bonding: set sysfs device_type to 'bond' bonding: fix bond_release_all inconsistencies b44: use netdev_alloc_skb_ip_align() xen: netback: remove redundant xenvif_put net: fec: Do a sanity check on the gpio number ip_gre: propogate target device GSO capability to the tunnel device ip_gre: allow CSUM capable devices to handle packets bonding: Fix initialize after use for 3ad machine state spinlock bonding: Fix race condition between bond_enslave() and bond_3ad_update_lacp_rate() ...

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc These changes contain the OMAP USB related platform data changes that were dropped from linux next because of the merge conflicts as requested by me and Olof. The reason was that at this point we really should be able to do the arch/arm related changes separately from driver changes to avoid dependencies between branches. These patches were initially part of the USB related MFD patches. Based on our comments, Roger Quadros quickly reworked these patches into a shared branch between ARM SoC tree and the MFD tree, then separate patches for the OMAP platform data and MFD driver. Note that this branch will conflict with c1d1cd597fc7 ("ARM: OMAP2+: omap_device: remove obsolete pm_lats and early_device code"). Please see http://lkml.org/lkml/2013/2/11/16 for the merge resolution. [arnd - resolved the merge conflict] Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2013-02-15ARM: omap2: include linux/errno.h in hwmod_resetArnd Bergmann1-0/+1
The newly created omap_hwmod_reset.c is missing an include of linux/errno.h in commit c02060d8 "ARM: OMAP4+: AESS: enable internal auto-gating during initial setup". It still works in omap2_defconfig, but not in all other combinations. Without this patch, building allmodconfig results in: arch/arm/mach-omap2/omap_hwmod_reset.c: In function 'omap_hwmod_aess_preprogram': arch/arm/mach-omap2/omap_hwmod_reset.c:47:11: error: 'EINVAL' undeclared (first use in this function) arch/arm/mach-omap2/omap_hwmod_reset.c:47:11: note: each undeclared identifier is reported only once for each function it appears in Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Tony Lindgren <tony@atomide.com> Cc: Paul Walmsley <paul@pwsan.com> Cc: Sebastien Guiriec <s-guiriec@ti.com>
