2017-03-21device-dax: utilize new cdev_device_add helper functionLogan Gunthorpe1-13/+5
Replace the open coded registration of the cdev and dev with the new device_add_cdev() helper. The helper replaces a common pattern by taking the proper reference against the parent device and adding both the cdev and the device.

2017-03-21device-dax: fix cdev leakDan Williams1-4/+11
If device_add() fails, cleanup the cdev. Otherwise, we leak a kobj_map() with a stale device number. As Jason points out, there is a small possibility that userspace has opened and mapped the device in the time between cdev_add() and the device_add() failure. We need a new kill_dax_dev() helper to invalidate any established mappings.

2017-03-17auxdisplay: Add HD44780 Character LCD supportGeert Uytterhoeven3-0/+337
The Hitachi HD44780 Character LCD Controller is commonly used on character LCDs that can display one or more lines of text. This driver supports character LCDs connected to GPIOs, using either a 4-bit or 8-bit data bus, and provides access through the charlcd core and /dev/lcd.

2017-03-17auxdisplay: charlcd: Add support for displays with more than two linesGeert Uytterhoeven1-9/+13
On displays with more than two lines, the additional lines are stored in the buffers used for the first two lines, but beyond the visible parts. Adjust the DDRAM address calculation to cater for this. When clearing the display, avoid writing more spaces than the actual size of the physical buffer.

2017-03-17auxdisplay: charlcd: Add support for 4-bit interfacesGeert Uytterhoeven1-6/+30
In 4-bit mode, 8-bit commands and data are written using two raw writes to the data interface: high nibble first, low nibble last. This must be handled by the low-level driver. However, as we don't know in which mode (4-bit or 8-bit) nor 4-bit phase the LCD was left, initialization must always be handled using raw writes, and needs to configure the LCD for 8-bit mode first.

2017-03-17auxdisplay: charlcd: Extract character LCD core from misc/panelGeert Uytterhoeven5-735/+887
Extract the character LCD core from the Parallel port LCD/Keypad Panel driver in the misc subsystem, and convert it into a subdriver in the auxdisplay subsystem. This allows the character LCD core to be used by other drivers later. Compilation is controlled by its own Kconfig symbol CHARLCD, which is to be selected by its users, but can be enabled manually for compile-testing. All functions changed their prefix from "lcd_" to "charlcd_", and gained a "struct charlcd *" parameter to operate on a specific instance. While the driver API thus is ready to support multiple instances, the current limitation of a single display (/dev/lcd has a single misc minor assigned) is retained. No functional changes intended.

2017-03-17drivers/misc: Add Aspeed LPC control driverCyril Bur3-0/+276
In order to manage server systems, there is typically another processor known as a BMC (Baseboard Management Controller) which is responsible for powering the server and other various elements, sometimes fans, often the system flash. The Aspeed BMC family which is what is used on OpenPOWER machines and a number of x86 as well is typically connected to the host via an LPC (Low Pin Count) bus (among others). The LPC bus is an ISA bus on steroids. It's generally used by the BMC chip to provide the host with access to the system flash (via MEM/FW cycles) that contains the BIOS or other host firmware along with a number of SuperIO-style IOs (via IO space) such as UARTs, IPMI controllers. On the BMC chip side, this is all configured via a bunch of registers whose content is related to a given policy of what devices are exposed at a per system level, which is system/vendor specific, so we don't want to bolt that into the BMC kernel. This started with a need to provide something nicer than /dev/mem for user space to configure these things. One important aspect of the configuration is how the MEM/FW space is exposed to the host (ie, the x86 or POWER). Some registers in that bridge can define a window remapping all or portion of the LPC MEM/FW space to a portion of the BMC internal bus, with no specific limits imposed in HW. I think it makes sense to ensure that this window is configured by a kernel driver that can apply some serious sanity checks on what it is configured to map. In practice, user space wants to control this by flipping the mapping between essentially two types of portions of the BMC address space: - The flash space. This is a region of the BMC MMIO space that more/less directly maps the system flash (at least for reads, writes are somewhat more complicated). - One (or more) reserved area(s) of the BMC physical memory. The latter is needed for a number of things, such as avoiding letting the host manipulate the innards of the BMC flash controller via some evil backdoor, we want to do flash updates by routing the window to a portion of memory (under control of a mailbox protocol via some separate set of registers) which the host can use to write new data in bulk and then request the BMC to flash it. There are other uses, such as allowing the host to boot from an in-memory flash image rather than the one in flash (very handy for continuous integration and test, the BMC can just download new images). It is important to note that due to the way the Aspeed chip lets the kernel configure the mapping between host LPC addresses and BMC ram addresses the offset within the window must be a multiple of size. Not doing so will fragment the accessible space rather than simply moving 'zero' upwards. This is caused by the nature of HICR8 being a mask and the way host LPC addresses are translated.

Instead of creating switch-specific attributes by hand, implement is_visible() method of attribute group and hide them when dealing with non-switch devices. This will ensure that all attributes are created together, before userspace gets notified of new device. Also, remove rio-sysfs.c from list of files that are scanned when compiling RapiodIO documentations as it no longer has any structured comments, and leaving it in leads to warning when building docs.

Merge 5-level page table prep from Kirill Shutemov: "Here's relatively low-risk part of 5-level paging patchset. Merging it now will make x86 5-level paging enabling in v4.12 easier. The first patch is actually x86-specific: detect 5-level paging support. It boils down to single define. The rest of patchset converts Linux MMU abstraction from 4- to 5-level paging. Enabling of new abstraction in most cases requires adding single line of code in arch-specific code. The rest is taken care by asm-generic/. Changes to mm/ code are mostly mechanical: add support for new page table level -- p4d_t -- where we deal with pud_t now. v2: - fix build on microblaze (Michal); - comment for __ARCH_HAS_5LEVEL_HACK in kasan_populate_zero_shadow(); - acks from Michal" * emailed patches from Kirill A Shutemov <kirill.shutemov@linux.intel.com>: mm: introduce __p4d_alloc() mm: convert generic code to 5-level paging asm-generic: introduce <asm-generic/pgtable-nop4d.h> arch, mm: convert all architectures to use 5level-fixup.h asm-generic: introduce __ARCH_USE_5LEVEL_HACK asm-generic: introduce 5level-fixup.h x86/cpufeature: Add 5-level paging detection

2017-03-10drm: mxsfb: Implement drm_panel handlingFabio Estevam1-0/+4
Currently when the 'power-supply' regulator is passed via device tree it does not actually work since drm_panel_prepare()/drm_panel_enable() are never called. Quoting Thierry Reding: "It should really call drm_panel_prepare() and drm_panel_enable() while switching on the display pipeline and drm_panel_disable(), followed by drm_panel_unprepare() while switching off the display pipeline." So do as suggested, so that the 'power-supply' regulator can be functional.

2017-03-10drm: mxsfb_crtc: Fix the framebuffer misplacementFabio Estevam1-2/+2
Currently the framebuffer content is displayed with incorrect offsets in both the vertical and horizontal directions. The fbdev version of the driver does not show this problem. Breno Lima dumped the eLCDIF controller registers on both the drm and fbdev drivers and noticed that the VDCTRL3 register is configured incorrectly in the drm driver. The fbdev driver calculates the vertical and horizontal wait counts of the VDCTRL3 register by doing: back porch + sync length. Looking at the horizontal and vertical timing diagram from include/drm/drm_modes.h this value corresponds to: crtc_[hv]total - crtc_[hv]sync_start So fix the VDCTRL3 register setting accordingly so that the eLCDIF controller can properly show the framebuffer content in the correct position.

2017-03-10drm: mxsfb: Fix crash when provided invalid DT bindingsMarek Vasut1-0/+4
The mxsfb driver will crash if the mxsfb DT node has a subnode, but the content of the subnode is not of-graph binding with an endpoint linking to panel. The crash was triggered by providing old-style panel bindings to the mxsfb driver instead of the new of-graph ones. The problem happens in mxsfb_create_output(), which is invoked from mxsfb_load(). The mxsfb_create_output() iterates over all mxsfb DT subnode endpoints and tries to bind a panel on each endpoint. If there is any problem binding the panel, that is, mxsfb->panel == NULL, this function will return an error code, otherwise success 0 is returned. If the subnodes do not specify of-graph binding with an endpoint, the iteration over endpoints in mxsfb_create_output() will have zero cycles and the function will immediatelly return 0, but the mxsfb->panel will remain NULL. This is propagated back into the mxsfb_load(), which does not detect any problem and expects that the mxsfb->panel is valid, thus calls mxsfb_panel_attach(). But since mxsfb->panel == NULL, mxsfb_panel_attach() is called with first argument NULL and this crashes the kernel. This patch fixes the problem by explicitly checking for valid mxsfb->panel at the end of the iteration in mxsfb_create_output().

2017-03-10drm: mxsfb: fix pixel clock polarityStefan Agner1-2/+9
The DRM subsystem specifies the pixel clock polarity from a controllers perspective: DRM_BUS_FLAG_PIXDATA_NEGEDGE means the controller drives the data on pixel clocks falling edge. That is the controllers DOTCLK_POL=0 (Default is data launched at negative edge). Also change the data enable logic to be high active by default and only change if explicitly requested via bus_flags. With that defaults are: - Data enable: high active - Pixel clock polarity: controller drives data on negative edge Signed-off-by: Stefan Agner <stefan@agner.ch> Acked-by: Marek Vasut <marex@denx.de> Signed-off-by: Dave Airlie <airlied@redhat.com>
2017-03-10drm: mxsfb: use bus_format to determine LCD bus widthStefan Agner2-2/+33
The LCD bus width does not need to align with the pixel format. The LCDIF controller automatically converts between pixel formats and bus width by padding or dropping LSBs. The DRM subsystem has the notion of bus_format which allows to determine what bus_formats are supported by the display. Choose the first available or fallback to 24 bit if none are available.
