2013-06-26OMAPDSS: DPI: Fix wrong pixel clock limitTomi Valkeinen
DPI is supposed to skip odd dividers in the clock path when the pixel clock is higher than 100MHz. The code, however, defines the pixel clock limit as 1MHz. This causes the driver to skip valid clock dividers, possibly making the pixel clock to be further away from the requested one than necessary. Fix the clock limit to 100MHz.

2013-06-24build some drivers only when compile-testingJiri Slaby
Some drivers can be built on more platforms than they run on. This is a burden for users and distributors who package a kernel. They have to manually deselect some (for them useless) drivers when updating their configs via oldconfig. And yet, sometimes it is even impossible to disable the drivers without patching the kernel. Introduce a new config option COMPILE_TEST and make all those drivers to depend on the platform they run on, or on the COMPILE_TEST option. Now, when users/distributors choose COMPILE_TEST=n they will not have the drivers in their allmodconfig setups, but developers still can compile-test them with COMPILE_TEST=y. Now the drivers where we use this new option: * PTP_1588_CLOCK_PCH: The PCH EG20T is only compatible with Intel Atom processors so it should depend on x86. * FB_GEODE: Geode is 32-bit only so only enable it for X86_32. * USB_CHIPIDEA_IMX: The OF_DEVICE dependency will be met on powerpc systems -- which do not actually support the hardware via that method. * INTEL_MID_PTI: It is specific to the Penwell type of Intel Atom device. [v2] * remove EXPERT dependency [gregkh - remove chipidea portion, as it's incorrect, and also doesn't apply to my driver-core tree] Signed-off-by: Jiri Slaby <jslaby@suse.cz> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Jeff Mahoney <jeffm@suse.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: linux-usb@vger.kernel.org Cc: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Cc: linux-geode@lists.infradead.org Cc: linux-fbdev@vger.kernel.org Cc: Richard Cochran <richardcochran@gmail.com> Cc: netdev@vger.kernel.org Cc: Ben Hutchings <ben@decadent.org.uk> Cc: "Keller, Jacob E" <jacob.e.keller@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-06-23console/font: Refactor font support code selection logicGeert Uytterhoeven
The current Makefile rules to build font support are messy and buggy. Replace them by Kconfig rules: - Introduce CONFIG_FONT_SUPPORT, which controls the building of all font code, - Select CONFIG_FONT_SUPPORT for all drivers that use fonts, - Select CONFIG_FONT_8x16 for all drivers that default to the VGA8x16 font, - Drop the bogus console dependency for CONFIG_VIDEO_VIVI, - Always process drivers/video/console/Makefile, as some drivers need fonts even if CONFIG_VT is not set. This fixes (if CONFIG_SOLO6X10=y and there are no built-in console drivers): drivers/built-in.o: In function `solo_osd_print': drivers/staging/media/solo6x10/solo6x10-enc.c:144: undefined reference to `.find_font' This fixes (if CONFIG_VT=n): drivers/built-in.o: In function `vivi_init': vivi.c:(.init.text+0x1a3da): undefined reference to `find_font' Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Acked-by: Hans Verkuil <hans.verkuil@cisco.com> [original part] Acked-by: Randy Dunlap <rdunlap@infradead.org> [drivers/video/Makefile]

2013-06-17OMAPDSS: public omapdss_register_output()Tomi Valkeinen
In order to allow multiple display block in a video pipeline, we need to give the drivers way to register themselves. For now we have the omapdss_register_display() which is used to register panels, and dss_register_output() which is used to register DSS encoders. This patch makes dss_register_output() public (with the name of omapdss_register_output), which can be used to register also external encoders. The distinction between register_output and register_display is that a "display" is an entity at the end of the videopipeline, and "output" is something inside the pipeline. The registration and naming will be made saner in the future, but the current names and functions are kept to minimize changes during the dss device model transition.

2013-06-17OMAPDSS: remove dispc's dependency to VENC/HDMITomi Valkeinen
DISPC needs to know the clock rate for DIGIT (i.e. TV) channel, and this clock is provided by either VENC or HDMI modules. Currently DISPC will call a function in VENC/HDMI, asking what the clock rate is. This means we have a fixed dependency from DISPC to both VENC and HDMI. To have a more generic approach, and in particular to allow adding OMAP5 HDMI driver, we need to remove this dependency. This patch makes VENC/HDMI inform DISPC when the their clock changes, thus reversing the dependency and removing the issue. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2013-06-17OMAPDSS: HDMI: clean up PHY power handlingTomi Valkeinen
The TRM tells to set PHY to TXON only after getting LINK_CONNECT, and to set PHY to OFF or LDOON after getting LINK_DISCONNECT, in order to avoid damage to the PHY. We don't currently do it quite like that. Instead of using the HDMI interrupts, we use HPD signal. This works, but is not actually quite correct, as HPD comes at a different time than LINK_CONNECT and LINK_DISCONNECT interrupts. Also, the HPD GPIO is a property of the TPD level shifter, not HDMI IP, so handling the GPIO in the HDMI driver is wrong. This patch implements the PHY power handling correctly, using the interrupts. There is a corner case that causes some additional difficulties: we may get both LINK_CONNECT and LINK_DISCONNECT interrupts at the same time. This is handled in the code by retrying: turning off the PHY, clearing the interrupt status, and re-enabling the PHY. This causes a new LINK_CONNECT interrupt to happen if a cable is connected.
