The DSI controllers are powered by a (typically 1.2V) regulator. Usually this is always on, so there was no need to support enabling or disabling it thus far. But in order not to consume any power when DSI is inactive, give the driver a chance to enable or disable the supply as needed. Signed-off-by: NThierry Reding <treding@nvidia.com>

Revert commit 18ebc0f4 "drm/tegra: hdmi: Enable VDD earlier for hotplug/DDC" and instead add a new supply for the +5V pin on the HDMI connector. The vdd-supply property refers to the regulator that supplies the AVDD_HDMI input on Tegra, rather than the +5V HDMI connector pin. This was never a problem before, because all boards had that pin hooked up to a regulator that was always on. Starting with Dalmore and continuing with Venice2, the +5V pin is controllable via a GPIO. For reasons unknown, the GPIO ended up as the controlling GPIO of the AVDD_HDMI supply in the Dalmore and Venice2 DTS files. But that's not correct. Instead, a separate supply must be introduced so that the +5V pin can be controlled separately from the supplies that feed the HDMI block within Tegra. A new hdmi-supply property is introduced that takes the place of the vdd-supply and vdd-supply is only enabled when HDMI is enabled rather than all the time.

Exynos drm hdmi driver used to get dummy hdmiphy clock to control the PMU bit for hdmiphy. This bit needs to be set before setting any resolution to hdmi hardware. This was handled using dummy hdmiphy clock which is removed here. PMU is already defined as system controller for exynos SoCs. Hdmi driver is modified to control the phy enable bit inside PMU using regmap interfaces. Devicetree binding document for hdmi is also updated.

Certain bridge chips use a GPIO to indicate the cable status instead of the I_DP_HPD pin. This adds an optional device-tree property, "samsung,hpd-gpio", to the exynos-dp controller which indicates that the specified GPIO should be used for hotplug detection. The GPIO is then set up as an edge-triggered interrupt where the rising edge indicates hotplug-in and the falling edge indicates hotplug-out.

This is another great example of trainwreck engineering: commit 2646a0e529 (ARM: edma: Add EDMA crossbar event mux support) added support for using EDMA on peripherals which have no direct EDMA event mapping. The code compiles and does not explode in your face, but that's it. 1) Reading an u16 array from an u32 device tree array simply does not work. Even if the function is named "edma_of_read_u32_to_s16_array". It merily calls of_property_read_u16_array. So the resulting 16bit array will have every other entry = 0. 2) The DT entry for the xbar registers related to xbar has length 0x10 instead of the real length: 0xfd0 - 0xf90 = 0x40. Not a real problem as it does not cross a page boundary, but wrong nevertheless. 3) But none of this matters as the mapping never happens: After reading nonsense edma_of_read_u32_to_s16_array() invalidates the first array entry pair, so nobody can ever notice the braindamage by immediate explosion. Seems the QA criteria for this code was solely not to explode when someone adds edma-xbar-event-map entries to the DT. Goal achieved, congratulations! Not really helpful if someone wants to use edma on a device which requires a xbar mapping. Fix the issues by: - annotating the device tree entry with "/bits/ 16" as documented in the of_property_read_u16_array kernel doc - make the size of the xbar register mapping correct - invalidating the end of the array and not the start This convoluted mess wants to be completely rewritten as there is no point to keep the xbar_chan array memory and the iomapping of the xbar regs around forever. Marking the xbar mapped channels as used should be done right there. But that's a different issue and this patch is small enough to make it work and allows a simple backport for stable.

由 Lorenzo Pieralisi 提交于
ARM arch timers are tightly coupled with the CPU logic and lose context on platform implementing HW power management when cores are powered down at run-time. Marking the arch timers as C3STOP regardless of power management capabilities causes issues on platforms with no power management, since in that case the arch timers cannot possibly enter states where the timer loses context at runtime and therefore can always be used as a high resolution clockevent device. In order to fix the C3STOP issue in a way compliant with how real HW works, this patch adds a boolean property to the arch timer bindings to define if the arch timer is managed by an always-on power domain. This power domain is present on all ARM platforms to date, and manages HW that must not be turned off, whatever the state of other HW components (eg power controller). On platforms with no power management capabilities, it is the only power domain present, which encompasses and manages power supply for all HW components in the system. If the timer is powered by the always-on power domain, the always-on property must be present in the bindings which means that the timer cannot be shutdown at runtime, so it is not a C3STOP clockevent device. If the timer binding does not contain the always-on property, the timer is assumed to be power-gateable, hence it must be defined as a C3STOP clockevent device.

This commit adds the necessary definitions for the PHY layer to recognize "qsgmii" as a valid PHY interface. A QSMII interface, as defined at http://en.wikipedia.org/wiki/Media_Independent_Interface#Quad_Serial_Gigabit_Media_Independent_Interface, is "is a method of combining four SGMII lines into a 5Gbit/s interface. QSGMII, like SGMII, uses LVDS signalling for the TX and RX data and a single LVDS clock signal. QSGMII uses significantly fewer signal lines than four SGMII busses." This type of MAC <-> PHY connection might require special handling on the MAC driver side, so it should be possible to express this type of MAC <-> PHY connection, for example in the Device Tree.
