2011-01-26console: rename acquire/release_console_sem() to console_lock/unlock()Torben Hohn
The -rt patches change the console_semaphore to console_mutex. As a result, a quite large chunk of the patches changes all acquire/release_console_sem() to acquire/release_console_mutex() This commit makes things use more neutral function names which dont make implications about the underlying lock. The only real change is the return value of console_trylock which is inverted from try_acquire_console_sem() This patch also paves the way to switching console_sem from a semaphore to a mutex.

2011-01-25drivers/video/bf537-lq035.c: Add missing IS_ERR testJulia Lawall
lcd_device_register may return ERR_PTR, so a check is added for this value before the dereference. All of the other changes reorganize the error handling code in this function to avoid duplicating all of it in the added case. In the original code, in one case, the global variable fb_buffer was set to NULL in error code that appears after this variable is initialized. This is done now in all error handling code that has this property. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier f; @@ f(...) { ... return ERR_PTR(...); } @@ identifier r.f, fld; expression x; statement S1,S2; @@ x = f(...) ... when != IS_ERR(x) ( if (IS_ERR(x) ||...)

2011-01-20kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

2011-01-13vgacon: check for efi machineYannick Heneault
It seems there is a small problem of VGA palette corruption on EFI machine. When the kernel initializes the architecture, it checks if the machine is a EFI machine and assumes that a VGA console can exist. When it initializes the console in vgacon_startup it checks if it can really use the VGA console. I think this is where a check is missing. Currently, the function can fail if a VESA boot mode is detected but not if a EFI boot mode was used. Thus vgacon_startup() doesn't fail and initialize the video card for a real VGA mode. This function changes the first 16entries of the VGA palette. When the efifb driver kicks in, the palette is not restored to default ramp value, thus the 16 first entry remain in a modified state. The following patch prevent this corruption. Signed-off-by: Yannick Heneault <yheneaul@matrox.com> Cc: Dave Airlie <airlied@linux.ie> Cc: "H.

2011-01-13drivers/video/backlight/l4f00242t03.c: fix reset sequenceAlberto Panizzo
The reset command is part of the init sequence and it take effect only if the lcd is powered. The effect of the bug was that the sequence: set lcd power_state to FB_BLANK_POWERDOWN set lcd power_state to FB_BLANK_UNBLANK Did not produced a complete reboot of the LCD which was showing fuzzy colours. This was not experienced before implementing correctly all the LCD power states with the patch [1]. Since before the patch [1] the regulators were not touched and the LCD shutdown was reached with a register write. After the patch [1] a complete boot sequence with an initial reset is needed for the display every time the LCD is powered up. drivers-video-backlight-l4f00242t03c-full-implement-fb-power-states-for-this-lcd.patch Signed-off-by: Alberto Panizzo <maramaopercheseimorto@gmail.com> Cc: Richard Purdie <rpurdie@rpsys.net> Cc: Marek Vasut <marek.vasut@gmail.com> Cc: Tejun Heo <tj@kernel.org> Cc: Axel Lin <axel.lin@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

If a command line option of the form "video=sh_mobile_lcdc:<width>x<height>@<refresh>" is provided, the driver will look for that mode among those, available in the monitor EDID. This patch adds the ability to request the driver to use monitor's preferred mode by specifying 0 as width and hight in the above string. If that mode is not supported by the system, the driver will continue scanning through EDID modes, until it finds a suitable one.

2011-01-10OMAP: DSS2: Introduce omap_channel as an omap_dss_device parameter, add new ↵Sumit Semwal
overlay manager. A panel connects to one of the overlay managers of DSS through some interface block. On OMAP4, specifying the type of the display is not sufficient to conclude which manager the panel should be connected to. Hence, a new member 'channel' is introduced in omap_dss_device structure to determine which manager the panel uses. The dss_recheck_connections() called in dss_driver_probe() uses this channel parameter to set the correct manager to the corresponding omap_dss_device. The channel parameter is used only once to ensure the correct managers are set for each panel. The parameter dssdev->manager->id will take care of ensuring that the panel and then the interface driver configures the correct DISPC channel. Also, add a new Overlay Manager in manager.c, make other changes needed for LCD2 channel.

DISPC functions are modified in order to work when the manager is LCD2. This includes: Adding new IRQs specific to LCD2 and their handling. Provide dumps of the new manager's registers. Provide dumps of the new manager's clocks. Checks for channel for registers DISPC_CONTROL2 and DISPC_CONFIG2 which can't be parametrized.

2011-01-10OMAP: DSS2: Introduce omap_channel argument to DISPC functions used by ↵Sumit Semwal
interface drivers The interface drivers (dsi.c, sdi.c etc) need to call dispc functions with dssdev->manager->id as a parameter to specify the DISPC channel which they want to configure/use, this is required as the same functions are now used to configure dispc registers of different channels. The following dispc functions are changed to incorporate channel as an argument: -dispc_enable_fifohandcheck() -dispc_set_lcd_size() -dispc_set_parallel_interface_mode() -dispc_set_tft_data_lines() -dispc_set_lcd_display_type() -dispc_set_lcd_timings() Signed-off-by: Sumit Semwal <sumit.semwal@ti.com> Signed-off-by: Mukund Mittal <mmittal@ti.com> Signed-off-by: Samreen <samreen@ti.com> Signed-off-by: Archit Taneja <archit@ti.com> [tomi.valkeinen@nokia.com: fixed trivial compile error] Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
2011-01-10OMAP: DSS2: Represent DISPC register defines with channel as parameterSumit Semwal
On OMAP4, we have a new DISPC channel for Overlay Manager LCD2. There is a set of regsiters for LCD2 channel similar to the existing LCD channel, like DISPC_CONTROL2, DISPC_DIVISOR2, DISPC_CONFIG2 and so on. Introduce new enum members for LCD2 Channel and corresponding Overlay Manager in display.h. Represent the following DISPC register defines with channel as a parameter to differentiate between LCD and LCD2 registers (and also DIGIT in some cases): DISPC_DEFAULT_COLOR, DISPC_TRANS_COLOR, DISPC_TIMING_H, DISPC_TIMING_V, DISPC_POL_FREQ, DISPC_DIVISOR, DISPC_SIZE_LCD, DISPC_DATA_CYCLEk, DISPC_CPR_COEF_R, DISPC_CPR_COEF_G and DISPC_CPR_COEF_B This parametrization helps in reducing the number of register defines for DISPC. Replace the existing reads/writes to these registers in this new way. Also, Introduce defines for registers DISPC_CONTROL2 and DISPC_CONFIG2 which are used exclusively for LCD2 channel.
