dss_feat_get_supported_displays() and dss_feat_get_supported_outputs() are not used outside omapdss, but are exported. We can thus remove the export and move the declarations to the omapdss internal header.

2015-12-29OMAPDSS: add setup for WB capture mode in dispc_wb_setup()Tomi Valkeinen1-0/+15
dispc_wb_setup() handles configuration only for mem-to-mem case. This patch adds the necessary configuration to handle also display capture mode. We need to set CAPTUREMODE to 0 (continuous capture), and WBDELAYCOUNT according to the vertical timings of the display, so that the WB FIFO has time to flush before the next frame starts.

2015-12-29OMAPDSS: skip pclk check for WB mem2memTomi Valkeinen1-1/+1
When doing mem-to-mem writeback, there's no pixelclock. However, the code that calculates scaling factors check that there is a pixel clock. We can just skip the check when doing mem-to-mem writeback. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

Add handling of OMAP_DSS_CHANNEL_WB to dispc_ovl_set_channel_out() and dispc_ovl_get_channel_out(). Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2015-12-29OMAPDSS: refactor dispc_ovl_get_channel_outTomi Valkeinen1-17/+14
Refactor dispc_ovl_get_channel_out() to a bit cleaner form, which makes it easier to add support for writeback in the following patch. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2015-12-29OMAPDSS: add OMAP_DSS_CHANNEL_WB to 'enum omap_channel'Tomi Valkeinen1-0/+1
'enum omap_channel' is missing the channel for writeback. Add that. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2015-12-29OMAPDSS: add 'has_writeback' flagTomi Valkeinen3-15/+7
At the moment we have a function to get the number of writeback pipelines supported. However, the function is used in a wrong way, causing a wrong pipeline to get configured when trying to use WB. Also, we only have a single writeback pipeline on any of the DSS versions. To fix and simplify this, create a 'has_writeback' flag into the dispc driver, and after checking the flag, use OMAP_DSS_WB pipeline explicitly when calling the configuration functions.

2015-12-29OMAPDSS: add num_wbs=1 to omap5 dss featuresTomi Valkeinen1-0/+1

2015-12-17OMAPDSS: DISPC: always set ALIGN when availableTomi Valkeinen1-0/+9
By default DISPC asserts hsync and vsync sequentially, i.e. there's first hsync and that is immediately followed by vsync. This is the only available behaviour on OMAP2/3, and default behaviour on OMAP4+. OMAP4+ has ALIGN bit in POL_FREQ register, which makes DISPC assert both syncs at the same time. It has been observed that some panels don't like sequential syncs (AM5 EVM's panel). After studying the datasheets for multiple panels and encoders, and MIPI DPI spec, it looks like there is no standard way to handle this. Sometimes the datasheets don't mention the required syncs behaviour at all, sometimes the datasheets have images that hint towards simultaneous syncs, and sometimes it is explicitly mentioned that simultaneous syncs are needed. No panels or encoders requiring sequential sync was found. It thus seems to be safe to default to simultaneous syncs when the ALIGN bit is available. This fixed AM5 EVM's panel, and no side effects have been observed on other panels or encoders.

2015-12-17OMAPDSS: adopt pinctrl supportDave Gerlach1-0/+6
Update omapdss driver to set the state of the pins to: - "default on resume - "sleep" on suspend By optionally putting the pins into sleep state in the suspend callback we can accomplish two things. - minimize current leakage from pins and thus save power, - prevent the IP from driving pins output in an uncontrolled manner, which may happen if the power domain drops the domain regulator.

2015-12-15video: fbdev: pxafb: initial devicetree conversionRobert Jarzmik2-3/+159
This patch brings a first support of pxa framebuffer devices to a devicetree pxa platform, as was before platform data. There are restrictions with this port, the biggest one being the lack of support of smart panels. Moreover the conversion doesn't provide a way to declare multiple framebuffer configurations with different bits per pixel, only the LCD hardware bus width is used. The patch was tested on both pxa25x, pxa27x and pxa3xx platform (namely lubbock, mainstone and zylonite).

2015-12-15fbdev: Debug knob to register without holding console_lockDaniel Vetter1-3/+11
When the usual fbcon legacy options are enabled we have ->register_framebuffer ->fb notifier chain calls into fbcon ->fbcon sets up console on new fbi ->fbi->set_par ->drm_fb_helper_set_par exercises full kms api And because of locking inversion hilarity all of register_framebuffer is done with the console lock held. Which means that the first time on driver load we exercise _all_ the kms code (all probe paths and modeset paths for everything connected) is under the console lock. That means if anything goes belly-up in that big pile of code nothing ever reaches logfiles (and the machine is dead). Usual tactic to debug that is to temporarily remove those console_lock calls to be able to capture backtraces. I'm fed up writing this patch and recompiling kernels. Hence this patch here to add an unsafe, kernel-taining option to do this at runtime.

2015-12-15fbdev: sm712fb: avoid unused function warningsArnd Bergmann1-13/+3
The sm712fb framebuffer driver encloses the power-management functions in #ifdef CONFIG_PM, but the smtcfb_pci_suspend/resume functions are only really used when CONFIG_PM_SLEEP is also set, as a frequent gcc warning shows: fbdev/sm712fb.c:1549:12: warning: 'smtcfb_pci_suspend' defined but not used fbdev/sm712fb.c:1572:12: warning: 'smtcfb_pci_resume' defined but not used The driver also avoids using the SIMPLE_DEV_PM_OPS macro when CONFIG_PM is unset, which is redundant. This changes the driver to remove the #ifdef and instead mark the functions as __maybe_unused, which is a nicer anyway, as it provides build testing for all the code in all configurations and is harder to get wrong.

The physical display tied to the framebuffer may have regulators providing power to it, such as power for LCDs or interface conversion chips. The number of regulators in use may vary, but the regulator supply binding can not be a list. Instead just support any named regulator supply properties under the device node. These should be properly named to match the device schematics / design. The driver should take care to go through them all.

Jan Stancek reported that I wrecked things for him by fixing things for Vladimir :/ His report was due to an UNINTERRUPTIBLE wait getting -EINTR, which should not be possible, however my previous patch made this possible by unconditionally checking signal_pending(). We cannot use current->state as was done previously, because the instruction after the store to that variable it can be changed. We must instead pass the initial state along and use that.

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 fixes from Catalin Marinas: - Update the linker script to use L1_CACHE_BYTES instead of hard-coded 64. We recently changed L1_CACHE_BYTES to 128 - Improve race condition reporting on set_pte_at() and change the BUG to WARN_ONCE. With hardware update of the accessed/dirty state, we need to ensure that set_pte_at() does not inadvertently override hardware updated state. The patch also makes the checks ignore !pte_valid() new entries * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: Improve error reporting on set_pte_at() checks arm64: update linker script to increased L1_CACHE_BYTES value
2015-12-12MIPS: fix DMA contiguous allocationQais Yousef1-1/+1
Recent changes to how GFP_ATOMIC is defined seems to have broken the condition to use mips_alloc_from_contiguous() in mips_dma_alloc_coherent(). I couldn't bottom out the exact change but I think it's this commit d0164adc89f6 ("mm, page_alloc: distinguish between being unable to sleep, unwilling to sleep and avoiding waking kswapd"). GFP_ATOMIC has multiple bits set and the check for !(gfp & GFP_ATOMIC) isn't enough. The reason behind this condition is to check whether we can potentially do a sleeping memory allocation. Use gfpflags_allow_blocking() instead which should be more robust.

2015-12-12sh64: fix __NR_fgetxattrDmitry V. Levin1-1/+1
According to arch/sh/kernel/syscalls_64.S and common sense, __NR_fgetxattr has to be defined to 259, but it doesn't. Instead, it's defined to 269, which is of course used by another syscall, __NR_sched_setaffinity in this case. This bug was found by strace test suite. Signed-off-by: Dmitry V.
