2016-04-25drm/fsl-dcu: use variable name dev for struct drm_deviceStefan Agner
The driver uses different variable names for struct drm_device across functions which is confusing. Stick to the more common variable name dev. While at it, remove unnecessary if statement in error handling. Signed-off-by: Stefan Agner <stefan@agner.ch>
2016-04-25drm/fsl-dcu: handle missing panel gracefullyStefan Agner
If the device tree property fsl,panel is missing, drm_panel_attach is called with a NULL pointer as first argument. Having a panel is basically mandatory since RGB is the only supported connector. Check if a panel node has been found, return -ENODEV and cleanup otherwise. Signed-off-by: Stefan Agner <stefan@agner.ch>

2016-04-25drm/layerscape: reduce excessive stack usageArnd Bergmann
The fsl-dcu driver copies a drm_mode_config object to its stack but then only accesses a single member (dpms_property) once. The data structure is large enough to trigger a warning about the amount of kernel stack being used: drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_rgb.c: In function 'fsl_dcu_drm_connector_create': drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_rgb.c:182:1: error: the frame size of 1040 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] This changes the fsl_dcu_drm_connector_create() function to only access the drm_mode_config by reference, which is also more efficient.

2016-04-25drm/fsl-dcu: add TCON driverStefan Agner
Add driver for the TCON (timing controller) module. The TCON module is a separate module attached after the DCU (display controller unit). Each DCU instance has its own, directly connected TCON instance. The DCU's RGB and timing signals are passing through the TCON module. TCON can provide timing signals for raw TFT panels or operate in a bypass mode which leaves all signals unaltered. The driver currently only supports the bypass mode.

2016-04-25drm/fsl-dcu: use common clock framework for pixel clock dividerStefan Agner
Use the common clock framework to calculate the pixel clock dividier. The previous implementation rounded down the calculated factor. Thanks to the CLK_DIVIDER_ROUND_CLOSEST flag using the common clock framework divider implementation improves the pixel clock accuracy in some cases. Ontop of that it also allows to see the actual pixel clock in the sysfs clock summary. Signed-off-by: Stefan Agner <stefan@agner.ch>

2016-04-25Input: twl6040-vibra - fix atomic schedule panicH. Nikolaus Schaller
commit c6f39257c952 ("mfd: twl6040: Use regmap for register cache") did remove the private cache for the vibra control registers and replaced access within twl6040_get_vibralr_status() by calls to regmap. This is OK, as long as twl6040_get_vibralr_status() uses already cached values or is not called from interrupt context. But we call this in vibra_play() for checking that the vibrator is not configured for audio mode. The result is a "BUG: scheduling while atomic" if the first use of the twl6040 is a vibra effect, because the first fetch is by reading the twl6040 registers through (blocking) i2c and not from the cache. As soon as the regmap has cached the status, further calls are fine. The solution is to move the condition to the work() function which runs in context that can block. The original code returns -EBUSY, but the return value of ->play() functions is ignored anyways. Hence, we do not loose functionality by not returning an error but just reporting the issue to INFO loglevel. Tested-on: Pyra (omap5) prototype Signed-off-by: H.

Commit 52cbae0127ad ("toshiba_acpi: Change default Hotkey enabling value") changed the hotkeys enabling value, as it was the same value Windows uses, however, it turns out that the value tells the EC that the driver will now take care of the hardware events like the physical RFKill switch or the pointing device toggle button.

2016-04-25[media] vb2-memops: Fix over allocation of frame vectorsRicardo Ribalda
On page unaligned frames, create_framevec forces get_vaddr_frames to allocate an extra page at the end of the buffer. Under some circumstances, this leads to -EINVAL on VIDIOC_QBUF. E.g: We have vm_a that vm_area that goes from 0x1000 to 0x3000. And a frame that goes from 0x1800 to 0x2800, i.e. 2 pages. frame_vector_create will be called with the following params: get_vaddr_frames(0x1800, 2, write, 1, vec); get_vaddr will allocate the first page after checking that the memory 0x1800-0x27ff is valid, but it will not allocate the second page because the range 0x2800-0x37ff is out of the vm_a range. This results in create_framevec returning -EFAULT Error Trace: [ 9083.793015] video0: VIDIOC_QBUF: 00:00:00.00000000 index=1, type=vid-cap, flags=0x00002002, field=any, sequence=0, memory=userptr, bytesused=0, offset/userptr=0x7ff2b023ca80, length=5765760 [ 9083.793028] timecode=00:00:00 type=0, flags=0x00000000, frames=0, userbits=0x00000000 [ 9083.793117] video0: VIDIOC_QBUF: error -22: 00:00:00.00000000 index=2, type=vid-cap, flags=0x00000000, field=any, sequence=0, memory=userptr, bytesused=0, offset/userptr=0x7ff2b07bc500, length=5765760 Also use true instead of 1 since that argument is a bool in the get_vaddr_frames() prototype.

2016-04-24net: stmmac: socfpga: Remove re-registration of reset controllerMarek Vasut
Both socfpga_dwmac_parse_data() in dwmac-socfpga.c and stmmac_dvr_probe() in stmmac_main.c functions call devm_reset_control_get() to register an reset controller for the stmmac. This results in an attempt to register two reset controllers for the same non-shared reset line. The first attempt to register the reset controller works fine. The second attempt fails with warning from the reset controller core, see below. The warning is produced because the reset line is non-shared and thus it is allowed to have only up-to one reset controller associated with that reset line, not two or more. The solution has multiple parts. First, the original socfpga_dwmac_init() is tweaked to use reset controller pointer from the stmmac_priv (private data of the stmmac core) instead of the local instance, which was used before. The local re-registration of the reset controller is removed. Next, the socfpga_dwmac_init() is moved after stmmac_dvr_probe() in the probe function. This order is legal according to Altera and it makes the code much easier, since there is no need to temporarily register and unregister the reset controller ; the reset controller is already registered by the stmmac_dvr_probe(). Finally, plat_dat->exit and socfpga_dwmac_exit() is no longer necessary, since the functionality is already performed by the stmmac core. ------------[ cut here ]------------ WARNING: CPU: 0 PID: 1 at drivers/reset/core.c:187 __of_reset_control_get+0x218/0x270 Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.6.0-rc4-next-20160419-00015-gabb2477-dirty #4 Hardware name: Altera SOCFPGA [<c010f290>] (unwind_backtrace) from [<c010b82c>] (show_stack+0x10/0x14) [<c010b82c>] (show_stack) from [<c0373da4>] (dump_stack+0x94/0xa8) [<c0373da4>] (dump_stack) from [<c011bcc0>] (__warn+0xec/0x104) [<c011bcc0>] (__warn) from [<c011bd88>] (warn_slowpath_null+0x20/0x28) [<c011bd88>] (warn_slowpath_null) from [<c03a6eb4>] (__of_reset_control_get+0x218/0x270) [<c03a6eb4>] (__of_reset_control_get) from [<c03a701c>] (__devm_reset_control_get+0x54/0x90) [<c03a701c>] (__devm_reset_control_get) from [<c041fa30>] (stmmac_dvr_probe+0x1b4/0x8e8) [<c041fa30>] (stmmac_dvr_probe) from [<c04298c8>] (socfpga_dwmac_probe+0x1b8/0x28c) [<c04298c8>] (socfpga_dwmac_probe) from [<c03d6ffc>] (platform_drv_probe+0x4c/0xb0) [<c03d6ffc>] (platform_drv_probe) from [<c03d54ec>] (driver_probe_device+0x224/0x2bc) [<c03d54ec>] (driver_probe_device) from [<c03d5630>] (__driver_attach+0xac/0xb0) [<c03d5630>] (__driver_attach) from [<c03d382c>] (bus_for_each_dev+0x6c/0xa0) [<c03d382c>] (bus_for_each_dev) from [<c03d4ad4>] (bus_add_driver+0x1a4/0x21c) [<c03d4ad4>] (bus_add_driver) from [<c03d60ac>] (driver_register+0x78/0xf8) [<c03d60ac>] (driver_register) from [<c0101760>] (do_one_initcall+0x40/0x170) [<c0101760>] (do_one_initcall) from [<c0800e38>] (kernel_init_freeable+0x1dc/0x27c) [<c0800e38>] (kernel_init_freeable) from [<c05d1bd4>] (kernel_init+0x8/0x114) [<c05d1bd4>] (kernel_init) from [<c01076f8>] (ret_from_fork+0x14/0x3c) ---[ end trace 059d2fbe87608fa9 ]--- Signed-off-by: Marek Vasut <marex@denx.de> Cc: Matthew Gerlach <mgerlach@opensource.altera.com> Cc: Dinh Nguyen <dinguyen@opensource.altera.com> Cc: David S.

2016-04-24drm/i915/bxt: Explicitly clear the Turbo control registerAkash Goel
As a part of WaGsvDisableTurbo, Driver makes an early exit from the Gen9 Turbo enabling function, so doesn't program the Turbo Control register. But BIOS could leave the Hw Turbo as enabled, so need to explicitly clear out the Control register just to avoid inconsitency with debugfs interface, which will show Turbo as enabled only and that is not expected after adding the WaGsvDisableTurbo. Apart from this there is no problem even if the Turbo is left enabled in the Control register, as the Up/Down interrupts would remain masked. v2: Add explicit clearing of Turbo Control register to *_disable_rps() also for the similar consistency (Chris) Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Akash Goel <akash.goel@intel.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: http://patchwork.freedesktop.org/patch/msgid/1461350146-23454-2-git-send-email-akash.goel@intel.com Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-04-24drm/i915: Correct the i915_frequency_info debugfs outputAkash Goel
There are certain registers, which captures the time elapsed in the in current Up/Down EI, for how long GT has been Idle/Busy/Avg in the current Up/Down EI and also in the previous Up/Down EI. These register values are reported by the i915_frequency_info debugfs interface. The Driver prints the 'us' suffix after the values, albeit they are actually in raw form & not in microsecond units. This patch removes the 'us' suffix so that its clear to User that values are indeed in raw form. v2: Present the values in microseconds unit also, after platform specific conversion (Chris) v3: Add a space between raw & microsecond value (Chris) Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Akash Goel <akash.goel@intel.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: http://patchwork.freedesktop.org/patch/msgid/1461350146-23454-3-git-send-email-akash.goel@intel.com Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
