Currently, clock database has <dev, clock-name> tuples for DSS2. Because of this, the clock names are different across different OMAP platforms. This patch aligns the DSS2 clock names and roles across OMAP 2420, 2430, 3xxx, 44xx platforms in the clock databases, hwmod databases for opt-clocks, and DSS clock handling. This ensures that clk_get/put/enable/disable APIs in DSS can use uniform role names.

DSS IRQ number can be obtained from platform_get_irq(). This API in turn picks the right IRQ number belonging to HW IP from the hwmod database. So hardcoding of IRQ number could be removed. This IRQ is stored in dss_irq as part of dss structure, and freed it in dss_exit().

Hwmod adaptation design requires each of the DSS HW IP to be a platform driver. So a platform_driver for DSI is created and init exit methods are moved from core.c to its driver probe,remove. pdev member has to be maintained by its own drivers. Also, vdds_dsi regulator handling is copied to dsi.c, since vdds_dsi regulator is needed by dpi_init() too. Board files are updated accordingly to add 2 instances of vdds_dsi regulator. DSI platform driver is registered from inside omap_dss_probe, in the order desired.

All clock management is moved to dss platform driver. clk_get/put APIs use dss device instead of core platform device. Hwmod adaptation design requires each of the DSS HW IP to be a platform driver. So the device name is changed from omapdss to omapdss_dss in 2420, 2430, 3xxx clock database files. Now the core driver "omapdss" only takes care of panel registration with the custom bus. core driver also uses the clk_enable() / clk_disable() APIs exposed by DSS for clock management. DSS driver would do clock management of clocks needed by DISPC, RFBI, DSI, VENC TODO: The clock content would be adapted to omap_hwmod in a seperate series.

As part of omap hwmod changes, DSS will not be the only controller of its clocks. hwmod initialization also enables the interface clocks, and manages them. So, when DSS is built as a module, omap_dss_remove doesn't try to disable all clocks that have a higher usecount.

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.

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) ||...)

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.

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: NYannick Heneault <yheneaul@matrox.com> Cc: Dave Airlie <airlied@linux.ie> Cc: "H.

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: NAlberto 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: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Currently, if no command-line option is specified, the sh_mobile_hdmi will use the default 720p video mode. 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.
