2011-09-01OMAP: DSS2: DISPC: Fix minimum PCD valuetilt-3.0-nodspvideo1-11-09-01Tomi Valkeinen
The current driver had a hardcoded minimum value of 2 for pixel clock divisor (PCD). This doesn't seem to be right. OMAP4 TRM says that PCD can be 1 when not downscaling, and inverted pixel clock (IPC) is off. OMAP3 TRM says the same, but also in the register descriptions that PCD value 1 is invalid. OMAP2 TRM says PCD 2 is the minimum. OMAP2 is still untested, but for both OMAP3 and OMAP4 PCD of 1 seems to work fine. This patch adds a new DSS feature, FEAT_PARAM_DSS_PCD, which is used to find the minimum and maximum PCD. The minimum is set to 2 for OMAP2, and 1 for OMAP3/4.

2011-09-01OMAP: DSS2: HDMI: change regn definitionTomi Valkeinen
regn divider is currently programmed to the registers without change, but when calculating clock frequencies it is used as regn+1. To make this similar to how DSI handles the dividers this patch changes the regn value to be used as such for calculations, but the value programmed to registers is regn-1. This simplifies the clock frequency calculations, makes it similar to DSI, and also allows us to use regn value 0 as undefined. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2011-09-01omap2+: add drm deviceRob Clark
Register drm platform device, and a platform device for pvr module in case it is loaded.. Maybe this should be added to a new file?
2011-09-01drm/omap: add common scaled modesRicardo Salveti de Araujo
The idea behind it is just to add more modes, and add them with reduced blanking, so we have more choices while probing the EDID. It tries to identify what would be the native mode for the monitor, and add the scaler modes that would be compatible with it, but with reduced blanking. With that it can get more compatible modes with OMAP pixel clock. Signed-off-by: Ricardo Salveti de Araujo <ricardo.salveti@canonical.com>

2011-09-01Add omap drm display driverRob Clark
A DSS based DRM display driver, which provides a plugin interface for 3d/2d accelerators to register. The core driver handles construction of CRTC/encoder/connectors to represent the hardware, and support KMS. This driver replaces omapfb. The omap drm driver allocates framebuffer memory and implements (with the help of drm_fb_helper) the legacy fbdev interface. The driver maps CRTCs to overlays, encoders to overlay-managers, and connectors to dssdev's.

2011-09-01gem: RFC: add support for private objectsAlan Cox
These small changes should allow GEM to be used with non shmem objects as well as shmem objects. In the GMA500 case it allows the base framebuffer to appear as a GEM object and thus acquire a handle and work with KMS. For i915 it ought to be trivial to get back the wasted memory but putting the system fb back into stolen RAM and in general I can imagine it allowing the use of GEM and thus KMS with all the older cards that have their framebuffer firmly placed in video RAM.

2011-09-01OMAP: DSS: HDMI: tame hdmi driverRob Clark
Main change is to avoid automatically picking timings. Now the driver defaults to a safe 640x480, and leaves it to the upper layer (drm driver) to pick the desired resolution based on what the user selects and the drm infrastucture's parsing of the EDID.

2011-08-28usb: ehci: fix update qtd->token in qh_append_tdsMing Lei
This patch fixs one performance bug on ARM Cortex A9 dual core platform, which has been reported on quite a few ARM machines(OMAP4, Tegra 2, snowball...), see details from link of https://bugs.launchpad.net/bugs/709245. In fact, one mb() on ARM is enough to flush L2 cache, but 'dummy->hw_token = token;' after mb() is added just for obeying correct mb() usage. The patch has been tested ok on OMAP4 panda A1 board, the performance of 'dd' over usb mass storage can be increased from 4~5MB/sec to 14~16MB/sec after applying this patch.

Subject: [PATCH] drivers:misc: ti-st: fail-safe on wrong pkt type Texas Instrument's shared transport driver interpret incoming data from the UART based on the various protocol drivers registered to the driver such as btwilink driver or FM or GPS driver which provide logical channel IDs. In case of bad-behavior from chip such as HCI Event response for a GPS command or a HCI Event (h/w error event) for a FM response & In case of bad-behavior from UART driver such as dropping data bytes a fail-safe is required to avoid kernel panic.
