Qualcomm msm targets had a bunch of code removal for legacy non-DT platforms. Nomadik saw more device tree conversions and cleanup of old code. Tegra has some code refactoring, etc. One longish patch series from Sebastian Hasselbarth changes the init_time hooks and tries to use a generic implementation for most platforms, since they were all doing more or less the same things. Finally the "shark" platform is removed in this release. It's been abandoned for a while and nobody seems to care enough to keep it around. If someone comes along and wants to resurrect it, the removal can easily be reverted and code brought back. Beyond this, mostly a bunch of removals of stale content across the board, etc" * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (79 commits) ARM: gemini: convert to GENERIC_CLOCKEVENTS ARM: EXYNOS: remove CONFIG_MACH_EXYNOS[4, 5]_DT config options ARM: OMAP3: control: add API for setting IVA bootmode ARM: OMAP3: CM/control: move CM scratchpad save to CM driver ARM: OMAP3: McBSP: do not access CM register directly ARM: OMAP3: clock: add API to enable/disable autoidle for a single clock ARM: OMAP2: CM/PM: remove direct register accesses outside CM code MAINTAINERS: Add patterns for DTS files for AT91 ARM: at91: remove init_machine() as default is suitable ARM: at91/dt: split sama5d3 peripheral definitions ARM: at91/dt: split sam9x5 peripheral definitions ARM: Remove temporary sched_clock.h header ARM: clps711x: Use linux/sched_clock.h MAINTAINERS: Add DTS files to patterns for Samsung platform ARM: EXYNOS: remove unnecessary header inclusions from exynos4/5 dt machine file ARM: tegra: fix ARCH_TEGRA_114_SOC select sort order clk: nomadik: fix missing __init on nomadik_src_init ARM: drop explicit selection of HAVE_CLK and CLKDEV_LOOKUP ARM: S3C64XX: Kill CONFIG_PLAT_S3C64XX ASoC: samsung: Use CONFIG_ARCH_S3C64XX to check for S3C64XX support ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OMAP3 PM code for off-mode currently saves the scratchpad contents for CM registers within OMAP control module driver. However, as we are separating CM code into its own driver, this must be moved also. This patch adds a new API for saving the CM scratchpad contents and uses this from the high level scratchpad save function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Users of the CM funtionality should not access the CM registers directly by themselves. Thus, added new CM driver APIs for the OMAP2 specific functionalities which support the existing direct register accesses, and changed the platform code to use these. This is done in preparation for moving the CM code into its own individual driver. Signed-off-by: Tero Kristo <t-kristo@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At least eight bytes of this number are totally unique for the device it seems, so this is a perfect candidate for feeding the entropy pool. One byte more or less of constants does not matter so feed in the entire OID struct. This fixes the issue of similar devices initializing to the same state initially. Further registers could be added too, such as OMAP4 CONTROL_STD_FUSE_OPP* and CONTROL_DPLL_NWELL_TRIM* registers, but those vary based on the SoC generation.

We can now enable VERBOSE_DEBUG on builds of drivers/usb/gadget/ by selecting CONFIG_USB_GADGET_VERBOSE. s3c-hsotg got quite a few non-critical fixes but also learned a few new tricks (isochronous transfers, multi count support). The Marvel USB3 Controller driver got a memory leak fix. devm_usb_get_phy() learned not to return NULL, ever. Other than these patches, we have the usual set of cleanups ranging from removal of unnecessary *_set_drvdata() to using SIMPLE_DEV_PM_OPS. Signed-of-by: Felipe Balbi <balbi@ti.com>

During the async mode setup, sync flags gets incorrectly set in the onenand_async data and the system crashes during the async setup. Also, the sync mode never gets set in gpmc_onenand_data->flags, so even without the crash, the actual sync mode setup would never be called. The patch fixes this by adjusting the gpmc_onenand_data->flags when the data is read from the DT. Also while doing this we force the onenand_async to be always async. The patch enables to use the following DTS chunk (that should correspond the arch/arm/mach-omap2/board-rm680.c board file setup) with Nokia N950, which currently crashes with 3.12-rc1. The crash output can be also found below. &gpmc { ranges = <0 0 0x04000000 0x20000000>; onenand@0,0 { #address-cells = <1>; #size-cells = <1>; reg = <0 0 0x20000000>; gpmc,sync-read; gpmc,sync-write;

So we have a clk_set_rate() done for a ABE DPLL node (which inturn locks it) followed by a clk_set_rate() for the USB DPLL. With USB DPLL being in bypass, we have this parent->child relationship thats formed while the clocks get registered. dpll_abe_ck | V dpll_abe_x2_ck | V dpll_abe_m3x2_ck | V usb_hs_clk_div_ck | V dpll_usb_ck This is because usb_hs_clk_div_ck is bypass clock for dpll_usb_ck. So with this parent->child relationship in place, a clk_set_rate() on ABE DPLL results eventually in a clk_set_rate() call on USB DPLL, because CCF does a clk_change_rate() (as part of clk_set_rate()) on all downstream clocks resulting from a rate change on the top clock. So its important that we lock USB DPLL before we lock ABE DPLL. Without which we see these error logs at boot.

A lot devices are using the smart-idle mode and so the write to the SYSCONFIG register is programming the same value that is already stored in the register. Writes to the devices SYSCONFIG register can be slow, for example, writing to the DMTIMER SYSCONFIG register takes 3 interface clock cycles and 3 functional clock cycles. If the DMTIMER is using the slow 32kHz functional clock this can take ~100us. Furthermore, during boot on an OMAP4430 panda board, I see that there are 100 calls to _idle_sysc(), however, only 3 out of the 100 calls actually write the SYSCONFIG register with a new value. Therefore, to avoid unnecessary writes to device SYSCONFIG registers when idling the device, only write the value if the value has changed. It should be safe to do this on idle as the context of the register will never be lost while the device is active. Verified that suspend, CORE off and retention states are working with this change on OMAP3430 Beagle board.
