* | drm/msm: don't install plane properties on crtcRob Clark2015-08-15
| | | | | | | | | | | | | | | | | | This was a hold-over from the pre-atomic days and legacy userspace that only understood CRTCs. Fortunately we don't have any properties, so this doesn't change anything. But before we start growing some plane properties, we should fix this. Signed-off-by: Rob Clark <robdclark@gmail.com>
* | drm/msm/dsi: Report PHY errors only when they really occurArchit Taneja2015-08-15
| | | | | | | | | | | | | | | | | | | | | | | | DSI PHY errors are falsely reported whenever a dsi error occurs. This is because DSI_DLN0_PHY_ERR isn't only used as a status register, but also used to mask PHY errors. Currently, we end up reading the mask bits too and therefore always report errors. Ignore the register mask bits and check for only the status/clear bits. Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
* | drm/msm: Set different display size limitation on each targetHai Li2015-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | The maximum output width of one pipeline depends on the LayerMixer's capability. It may be different on each target. Also, MDP5 doesn't have vertical limitation in one frame, as long as the pixel clock can be supported. This change obtains the maximum LM resolution from configuration table and treat it as the whole pipe's limitation for MDP5. The size limit on MDP4 is not changed.

* | drm/msm/hdmi: remove ->reset() from HDMI PHYStephane Viau2015-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ->reset() currently only accesses HDMI core registers, and yet it is located in hdmi_phy*. Since no PHY registers are being accessed during ->reset(), it would be better to bring that function in hdmi core module where HDMI core registers are usually being accessed. This will also help for msm8x94 for which no PHY registers accesses are done (->phy_init == NULL) but the HDMI PHY reset from HDMI core still needs to be done. Note: SW_RESET_PLL bit is not written in hdmi_phy_8x60_reset(); this write should not affect anything if the corresponding field is not writable.

This change adds the H/W difference to PHY configuration and updates the interface between DSI manager and PHY. With this change, PLL selection can be supported on different targets.

* drm/msm: use devm_gpiod_get_optional for optional reset gpioUwe Kleine-König2015-06-11
| | | | | | | | | | | | | | | | | | | | | | Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Also there is a variant to find optional gpios that returns NULL if there is no gpio instead of -ENOENT. Make use of both features to simplify the driver. This makes error checking more strict because errors like -ENOSYS ("no gpio support compiled in") or -EPROBE_DEFER ("gpio not ready yet") are handled correctly now. Furthermore this is one caller less that stops us making the flags argument to gpiod_get*() mandatory.
