As per the OMAP4 documentation, audio over HDMI must be transmitted in no-idle mode. This patch adds the HWMOD_SWSUP_SIDLE so that omap_hwmod uses no-idle/force-idle settings instead of smart-idle mode. This is required as the DSS interface clock is used as functional clock for the HDMI wrapper audio FIFO. If no-idle mode is not used, audio could be choppy, have bad quality or not be audible at all.

Until the OMAP4 code is converted to disable the use of the clock framework-based clockdomain enable/disable sequence, any clock used as a hwmod main_clk must have a clockdomain associated with it. This patch populates some clock structure clockdomain names to resolve the following warnings during kernel init: omap_hwmod: dpll_mpu_m2_ck: missing clockdomain for dpll_mpu_m2_ck. omap_hwmod: trace_clk_div_ck: missing clockdomain for trace_clk_div_ck. omap_hwmod: l3_div_ck: missing clockdomain for l3_div_ck. omap_hwmod: ddrphy_ck: missing clockdomain for ddrphy_ck.

Commit e813a55e ("OMAP: board-files: remove custom PD GPIO handling for DVI output") moved TFP410 chip's powerdown-gpio handling from the board files to the tfp410 driver. One gpio_request_one(powerdown-gpio, ...) was mistakenly left unremoved in the Beagle board file. This causes the tfp410 driver to fail to request the gpio on Beagle, causing the driver to fail and thus the DVI output doesn't work. This patch removes several boot errors from board-omap3beagle.c: - gpio_request: gpio--22 (DVI reset) status -22 - Unable to get DVI reset GPIO There is a combination of leftover code and revision confusion. Additionally, xM support is currently a hack. For original Beagleboard this removes the double initialization of GPIO 170, properly configures it as an output, and wraps the initialization in an if block so that xM does not attempt to request it. For Beagleboard xM it removes reference to GPIO 129 which was part of rev A1 and A2 designs, but never functioned. It then properly assigns beagle_dvi_device.reset_gpio in beagle_twl_gpio_setup and removes the hack of initializing it high. Additionally, it uses gpio_set_value_cansleep since this GPIO is connected through i2c. Unfortunately, there is no way to tell the difference between xM A2 and A3. However, GPIO 129 does not function on rev A1 and A2, and the TWL GPIO used on A3 and beyond is not used on rev A1 and A2, there are no problems created by this fix. Tested on Beagleboard-xM Rev C1 and Beagleboard Rev B4. Signed-off-by: NRuss Dill <Russ.Dill@ti.com> Acked-by: NTomi Valkeinen <tomi.valkeinen@ti.com> Signed-off-by: NTony Lindgren <tony@atomide.com>

Commit 62285963 (usb: musb: drop a gigantic amount of ifdeferry) got rid of a bunch of ifdefs in the MUSB code. Looks like the platform init code is still using these dropped defines though, which in many cases results the board defaulting always to host mode. Currently the situation is that USB_MUSB_HDRC is the main Kconfig option with additional USB_GADGET_MUSB_HDRC so only these two should be used to select between host and OTG mode. Fix the situation for omaps.

When the ethernet driver was built as a module, it would lock the machine when loaded. At boot the ethernet clks are unused, so get turned off. Later, when the module is loaded, the probe function would access the hardware before the clock was restarted, and the machine would lock. It has also been determined that when the clk is turned off, the interface forgets its MAC address, which for most systems, is set by the boot loader. When the machine setup file creates a platform device for the interface, prepare and enable the clock for the interface. This will ensure it is not turned off. However, if the setup file only instantiates one platform device, the other will have its clk disabled, thus maybe saving a little power.

With commit 4d5fc58d (ARM: remove bunch of now unused mach/io.h files), the I/O space setup was completely broken on versatile. This patch fixes that and prepares for further I/O space clean-up. I/O space handling on the versatile platform is currently broken in multiple ways. Most importantly, the ports do not get mapped into the virtual address space at all. Also, there is some amount of confusion between PCI I/O space and other statically mapped MMIO registers in the platform code: * The __io_address() macro that is used to access the platform register maps to the same __io macro that gets used for I/O space. * The IO_SPACE_LIMIT is set to a value that is much larger than the total available space. * The I/O resource of the PCI bus is set to the physical address of the mapping, which is way outside of the actual I/O space limit as well as the address range that gets decoded by traditional PCI cards. * No attempt is made to stay outside of the ISA port range that some device drivers try access. * No resource gets requested as a child of ioport_resource, but an IORESOURCE_IO type mapping gets requested as a child of iomem_resource. This patch attempts to correct all of the above. This makes it possible to use virtio-pci based virtual devices as well as actual PCI cards including those with legacy ISA port ranges like VGA. Some of the issues seem to be duplicated on other platforms.

To be more exact, the object_idr buffer is filled with zeros because of kzalloc(), but the dev_priv->object_idr.lock spinlock can cause system freeze at lib/idr.c:move_to_free_list() when spin_lock_irqsave() is called on this spinlock. The patch was tested on Clevo D4J, model D410J laptop, on the following hardware, without AGP kernel module loaded: # lspci -s 01:00.0 -n 01:00.0 0300: 1106:3108 (rev 01) # lspci -s 01:00.0 -v 01:00.0 VGA compatible controller: VIA Technologies, Inc.

Minchan Kim reports that when a system has many swap areas, and tmpfs swaps out to the ninth or more, shmem_getpage_gfp()'s attempts to read back the page cannot locate it, and the read fails with -ENOMEM. Whoops. Yes, I blindly followed read_swap_header()'s pte_to_swp_entry( swp_entry_to_pte()) technique for determining maximum usable swap offset, without stopping to realize that that actually depends upon the pte swap encoding shifting swap offset to the higher bits and truncating it there. Whereas our radix_tree swap encoding leaves offset in the lower bits: it's swap "type" (that is, index of swap area) that was truncated. Fix it by reducing the SWP_TYPE_SHIFT() in swapops.h, and removing the broken radix_to_swp_entry(swp_to_radix_entry()) from read_swap_header(). This does not reduce the usable size of a swap area any further, it leaves it as claimed when making the original commit: no change from 3.0 on x86_64, nor on i386 without PAE; but 3.0's 512GB is reduced to 128GB per swapfile on i386 with PAE. It's not a change I would have risked five years ago, but with x86_64 supported for ten years, I believe it's appropriate now. Hmm, and what if some architecture implements its swap pte with offset encoded below type? That would equally break the maximum usable swap offset check. Happily, they all follow the same tradition of encoding offset above type, but I'll prepare a check on that for next.
