* | msm: mdss: Add error check for cmds_tx and cmds_rx APIsJayant Shekhar2016-03-23
| | | | | | | | | | | | | | | | | | | | | | Currently in the MDSS DSI driver, there is no error checking and return for add, dma_tx and dma_rx functions in cmds_tx and cmds_rx APIs in case read or write operations fails. So, added error checks and return messages. Also, enable irq after dma_add in cmds_rx in correspondence with cmdx_tx api.

| | | | | | | | | | | | | | | | | | | | | | This change enables pass-through of TMDS signals through MHL Tx for sinks that have non-standard DCAP INT STAT SIZE in the devcap bytes. This facilitates MHL display on certain non-standard MHL sinks. CRs-Fixed: 504730 Change-Id: Id847cd25642e9eac8d559cc5dd3e1ab1046ebcce Signed-off-by: Ajay Singh Parmar <aparmar@codeaurora.org>

| | | | | | | | | | | | | | | | | | When virtual ctl is allocated during simultaneous wb line and block mode operation, the virtual ctl num should be the same as original ctl.

* | msm8974: mhl: set hpd, tmds based on path_en bitAbhishek Kharbanda2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Set HPD and TMDS pass-through only after receiving PATH_EN from the sink and reading all device capability bytes from the sink. Making MHL wait until the PATH_EN bit has been set by the sink/dongle is in conformance with the MHL spec. This change prevents incorrect behavior in usecases such as meeting timing requirements in test 1A-02 HDCP compliance test suite, disabling hpd when TV is powered off with MHL cable connected to the TX.

* | msm: mdss: Restrict SMP buffer reservationMayank Chopra2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Given two line latency buffer requirement for performance, in some cases, three or more SMP blocks get reserved. This happens typically for the usecases involving higher resolution layers (e.g. 1080P). For these usecases required number of SMP blocks exceed total number of SMP blocks available, thus causing SMP reservation failures. These failures are often encountered in 8x26 target as it has in total, only seven SMP blocks available. Restrict SMP buffer reservation to two SMP blocks, based on an optionable device tree property, to be able to support most of the usecases. This restriction is not applicable to horizontal flip cases where two line latency buffer reservation is necessary.
