[PATCH 2/2] OMAPDSS: DISPC: Fix scaling constraints for OMAP4

2012-01-29 Thread Archit Taneja
The calculation of required DISPC_FCLK for downscaling is done by multplying the pixel clock with an integer factor. This isn't true for OMAP4 where the required clock is calculated using the exact ratio of downscaling done. Fix this calculation for OMAP4. Also, do a minor clean up of calc_fclk().

[PATCH 1/2] OMAPDSS: Features: Maintain dss_feats as a list

2012-01-29 Thread Archit Taneja
The number of dss_feat_id members has increased to a large value, the current way of assigning a subset of these features (for a particular OMAP) as a mask is no longer feasible. Maintain the subset of features supported as lists. Make the function dss_has_feature() traverse through this list. Si

2012-01-29 Thread Grazvydas Ignotas
Hello, I've been trying to get suspend working with musb compiled in on 3.2. It seems both patches from this thread are needed, Kevin's patch stops omap2430_runtime_suspend() from being called at inappropriate time (when i2c is suspended [1]) and Felipe's patch brings that call back at better time

Hi, Ok, so I did a few more tests and there is a serious issue when sampling in frequency mode (the default). I noticed wrong number of samples, so I investigated this some more and instrumented the perf_event kernel code. I found some erratic timer ticks causing broken period adjustments. In fac

Question about tracing in _pwrdm_state_switch()

2012-01-29 Thread Paul Walmsley
Hi Jean Quick question on the tracing in _pwrdm_state_switch(). That section of the code reads: state = pwrdm_read_pwrst(pwrdm); ... case PWRDM_STATE_PREV: prev = pwrdm_read_prev_pwrst(pwrdm); if (pwrdm->state != prev) pw
