* OMAPDSS: DSS: Relax L3 bus bandwidth constraintTaras Kondratiuk2012-09-044-21/+54
| | | | | | | | | | | | | | | In a current codebase L3 BW constraint is set if any display has resution higher or equal FullHD. Estimated available DSS bandwidth on L3@OPP50 is ~800MB/s. It is approximately 3 WXGA layers or almost 1.5 FullHD layers at 60fps rate. This patch relaxes L3 BW constraint and set it only if current overlays' configuration needs higher BW.

* OMAPDSS: DSS: SyncLost WA for wb m2m-manager mode.Artem Rudenko2012-07-173-9/+44
| | | | | | | | | | | | | This is a workaround that prevents SYNC_LOST on changing pipe channelout from manager which was used as a source of wb to another manager. Manager could free pipes after wb will send SYNC message but that will start wb capture. To prevent that we reconnect the pipe from the manager to wb and do a dummy enabling and disabling of wb - the pipe will be freed and capture won't start because source pipe is switched off.

* OMAPDSS: DSS: fix for black frames in mem2mem modeSergiy Kibrik2012-07-111-0/+7
| | | | | | | | | | | | | | This change fixes black frames issue in MEM2MEM mode. The root of the problem is in apply_irq_handler function, which time-to-time is called between calls to omap_dss_wb_apply() and omap_dss_mgr_apply() functions. So, apply_irq_handler sometimes is called when WB cache was updated, but managr cache and others caches were not updated yet.

* OMAPDSS: DSS: workaround for errata i642Mykhailo Denysiuk2012-07-114-13/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change adds workaround for errata i642. Description of Errata i642: VID /GFX Pipeline Underflow Interrupt Generated When In WB Memory-to-memory Operation. Errata ID: i642. Recommended workaround: Software should disable the VID/GFX pipeline underflow interrupt by writing 0x0 in DISPC_IRQENABLE[20-12-10-6] bit if it is connected to the WB pipeline in memory-to-memory mode. Software should not consider the underflow interrupt generated in DISPC_IRQSTATUS[20-12-10-6] bit when in memory-to-memory mode. This change do not disable interrupt, but ignores its handler in case if pipeline connected to the manager, which is used in MEM2MEM mode.

The main idea is to connect write back (WB) pipeline to the manager (overlay, in terms of technical reference manual) which is not in use (physical interface is turned-off) for using advantages of hardware manager in M2M mode. In this case several pipelines can be connected to the manager.

Issue: Mstandby and disconnect protocol issue impacts: all OMAP4 devices Simplfied Description: issue #1: The handshake between IP modules on L3_1 and L3_2 peripherals with PRCM has a limitation in a certain time window of L4 clock cycle. Due to the fact that a wrong variant of stall signal was used in circuit of PRCM, the intitator-interconnect protocol is broken when the time window is hit where the PRCM requires the interconnect to go to idle while intitator asks to wakeup. Issue #2: DISPC asserts a sub-mstandby signal for a short period. In this time interval, IP block requests disconnection of Master port, and results in Mstandby and wait request to PRCM. In parallel, if mstandby is de-asserted by DISPC simultaneously, interconnect requests for a reconnect for one cycle alone resulting in a disconnect protocol violation and a deadlock of the system. Workaround: L3_1 clock domain must not be programmed in HW_AUTO if Static dependency with DSS is enabled and DSS clock domain is ON. Same for L3_2. Patch with changeID I28ae362ad330a79a493927575c9570462c4303a7 (omap: dispc: force L3_1 CD to NOSLEEP when dispc module is active) already introduces the work around for L3_1. Here we add L3_2 clock domain as well + update the comments and wrap the WA under an OMAP4 flag.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the DSS FIFO optimizations, ramdom lockups and reboots are seen. It has been identified that L3_1 CD is idling and not responding to the traffic initiated by DSS. The Workaround suggested by Hardware team is to keep the L3_1 CD in NO_SLEEP mode, when DSS is active. Once DSS module is switched to idle mode, put L3_1 CD to HW_AUTO.

* | OMAP4: DSI: Reset required disable-enable sequenceSujeet Baranwal2012-02-171-0/+6
| | | | | | | | | | | | | | | | | | | | During the initialization of DSI,some times BTA sent by OMAP DSI, was not receiving an BTA ACK. To rectify this, we need to reset the DSI module whenever we diable-enable the DSI module.
