2012-02-29OMAPDSS: APPLY: make ovl_enable/disable synchronousTomi Valkeinen1-0/+6
ovl->enable/disable are meant to be synchronous so that they can handle the configuration of fifo sizes. The current kernel doesn't configure fifo sizes yet, and so the code doesn't need to block to function (from omapdss driver's perspective). However, for the users of omapdss a non-blocking ovl->disable is confusing, because they don't know when the memory area is not used any more. Furthermore, when the fifo size configuration is added in the next merge window, the change from non-blocking to blocking could cause side effects to the users of omapdss. So by making the functions block already will keep them behaving in the same manner. And, while not the main purpose of this patch, this will also remove the compile warning: drivers/video/omap2/dss/apply.c:350: warning: 'wait_pending_extra_info_updates' defined but not used Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

2012-02-24viafb: select HW scaling on VX900 for IGA2Florian Tobias Schandinat1-0/+1
VX900 can do hardware scaling for both IGAs in contrast to previous hardware which could do it only for IGA2. This patch ensures that we set the parameter for IGA2 and not for IGA1. This fixes hardware scaling on VX900 until we have the infrastructure to support it for both IGAs. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Cc: stable@vger.kernel.org

2012-02-23OMAPDSS: HDMI: hot plug detect fixRob Clark1-8/+1
The "OMAPDSS: HDMI: PHY burnout fix" commit switched the HDMI driver over to using a GPIO for plug detect. Unfortunately the ->detect() method was not also updated, causing HDMI to no longer work for the omapdrm driver (because it would actually check if a connection was detected before attempting to enable display).

2012-02-23OMAPDSS: HACK: Ensure DSS clock domain gets out of idle when HDMI is enabledArchit Taneja1-1/+23
For DSS clock domain to transition from idle to active state. It's necessary to enable the optional clock DSS_FCLK before we enable the module using the MODULEMODE bits in the clock domain's CM_DSS_DSS_CLKCTRL register. This sequence was not followed correctly for the 'dss_hdmi' hwmod and it led to DSS clock domain not getting out of idle when pm_runtime_get_sync() was called for hdmi's platform device. Since the clock domain failed to change it's state to active, the hwmod code disables any clocks it had enabled before for this hwmod. This led to the clock 'dss_48mhz_clk' gettind disabled. When hdmi's runtime_resume() op is called, the call to dss_runtime_get() correctly enables the DSS clock domain this time. However, the clock 'dss_48mhz_clk' is needed for HDMI's PHY to function correctly. Since it was disabled previously, the driver fails when it tries to enable HDMI's PHY. Fix this for now by ensuring that dss_runtime_get() is called before we call pm_runtime_get_sync() for hdmi's platform device. A correct fix for later would be to modify the DSS related hwmod's mainclks, and also some changes in how opt clocks are handled in the DSS driver. This fixes the issue of HDMI not working when it's the default display. The issue is not seen if any other display is already enabled as the first display would have correctly enabled the DSS clockdomain.

2012-02-09ARM: omap: fix oops in drivers/video/omap2/dss/dpi.cRussell King1-0/+5
When a PMIC is not found, this driver is unable to obtain its 'vdds_dsi_reg' regulator. Even through its initialization function fails, other code still calls its enable function, which fails to check whether it has this regulator before asking for it to be enabled. This fixes the oops, however a better fix would be to sort out the upper layers to prevent them calling into a module which failed to initialize.

2012-01-26OMAPDSS: HDMI: PHY burnout fixTomi Valkeinen3-4/+71
A hardware bug in the OMAP4 HDMI PHY causes physical damage to the board if the HDMI PHY is kept powered on when the cable is not connected. This patch solves the problem by adding hot-plug-detection into the HDMI IP driver. This is not a real HPD support in the sense that nobody else than the IP driver gets to know about the HPD events, but is only meant to fix the HW bug. The strategy is simple: If the display device is turned off by the user, the PHY power is set to OFF. When the display device is turned on by the user, the PHY power is set either to LDOON or TXON, depending on whether the HDMI cable is connected. The reason to avoid PHY OFF when the display device is on, but the cable is disconnected, is that when the PHY is turned OFF, the HDMI IP is not "ticking" and thus the DISPC does not receive pixel clock from the HDMI IP. This would, for example, prevent any VSYNCs from happening, and would thus affect the users of omapdss. By using LDOON when the cable is disconnected we'll avoid the HW bug, but keep the HDMI working as usual from the user's point of view. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2012-01-26OMAPDSS: use sync versions of pm_runtime_putTomi Valkeinen6-6/+6
omapdss doesn't work properly on system suspend. The problem seems to be the fact that omapdss uses pm_runtime_put() functions when turning off the hardware, and when system suspend is in process only sync versions are allowed. Using non-sync versions normally and sync versions when suspending would need rather ugly hacks to convey the information of suspending/not-suspending to different functions. Optimally the driver wouldn't even need to care about this, and the PM layer would handle syncing when suspend is in process. This patch changes all omapdss's pm_runtime_put calls to pm_runtime_put_sync. This fixes the suspend problem, and probably the performance penalty of always using sync versions is negligible.

2012-01-12module_param: make bool parameters really bool (drivers/video/i810)Rusty Russell1-5/+5
module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option.
