Revert changes done in commit f6ec9483 ("drm/i915: extend audio CDCLK>=2*BCLK constraint to more platforms"). Audio drivers communicate with i915 over HDA bus multiple times during system boot-up and each of these transactions result in matching get_power/put_power calls to i915, and depending on the platform, a modeset change causing visible flicker. GLK is the only platform with minimum CDCLK significantly lower than BCLK, and thus for GLK setting a higher CDCLK is mandatory. For other platforms, minimum CDCLK is close but below 2*BCLK (e.g. on ICL, CDCLK=176.4kHz with BCLK=96kHz). Spec-wise the constraint should be set, but in practise no communication errors have been reported and the downside if set is the flicker observed at boot-time. Revert to old behaviour until better mechanism to manage probe-time clocks is available. The full CDCLK>=2*BCLK constraint is still enforced at pipe enable time in intel_crtc_compute_min_cdclk().

The last remaining reason for serialising the pin/unpin of the intel_context is to ensure that our preallocated wakerefs are not consumed too early (i.e. the unpin of the previous phase does not emit the idle barriers for this phase before we even submit). All of the other operations within the context pin/unpin are supposed to be atomic... Therefore, we can reduce the serialisation to being just on the i915_active.preallocated_barriers itself and drop the nested pin_mutex from intel_context_unpin(). Signed-off-by:

On Bay Trail devices the MIPI power on/off sequences for DSI LCD panels do not control the LCD panel- and backlight-enable GPIOs. So far, when the VBT indicates we should use the SoC for backlight control, we have been relying on these GPIOs being configured as output and driven high by the Video BIOS (GOP) when it initializes the panel. This does not work when the device is booted with a HDMI monitor connected as then the GOP will initialize the HDMI instead of the panel, leaving the panel black, even though the i915 driver tries to output an image to it. Likewise on some device-models when the GOP does not initialize the DSI panel it also leaves the mux of the PWM0 pin in generic GPIO mode instead of muxing it to the PWM controller. This commit makes the DSI code control the SoC GPIOs for panel- and backlight-enable on BYT, when the VBT indicates the SoC should be used for backlight control. It also ensures that the PWM0 pin is muxed to the PWM controller in this case. This fixes the LCD panel not lighting up on various devices when booted with a HDMI monitor connected. This has been tested to fix this on the following devices: Peaq C1010 Point of View MOBII TAB-P800W Point of View MOBII TAB-P1005W Terra Pad 1061 Yours Y8W81 Reviewed-by:

Move the Crystal Cove PMIC panel GPIO lookup-table from drivers/mfd/intel_soc_pmic_core.c to the i915 driver. The moved looked-up table is adding a GPIO lookup to the i915 PCI device and the GPIO subsys allows only one lookup table per device, The intel_soc_pmic_core.c code only adds lookup-table entries for the PMIC panel GPIO (as it deals only with the PMIC), but we also need to be able to access some GPIOs on the SoC itself, which requires entries for these GPIOs in the lookup-table. Since the lookup-table is attached to the i915 PCI device it really should be part of the i915 driver, this will also allow us to extend it with GPIOs from other sources when necessary. Acked-by:

When the LCD has not been turned on by the firmware/GOP, because e.g. the device was booted with an external monitor connected over HDMI, we should not turn on the panel-enable GPIO when we request it. Turning on the panel-enable GPIO when we request it, means we turn it on too early in the init-sequence, which causes some panels to not correctly light up. This commits adds a panel_is_on parameter to intel_dsi_vbt_gpio_init() and makes intel_dsi_vbt_gpio_init() set the initial GPIO value accordingly. This fixes the panel not lighting up on a Thundersoft TST168 tablet when booted with an external monitor connected over HDMI.

On some older devices (BYT, CHT) which may use v2 VBT MIPI-sequences, we need to manually control the panel enable GPIO as v2 sequences do not do this. So far we have been carrying the code to do this on BYT/CHT devices with a Crystal Cove PMIC in vlv_dsi.c, but as this really is a shortcoming of the VBT MIPI-sequences, intel_dsi_vbt.c is a better place for this, so move it there. This is a preparation patch for adding panel-enable and backlight-enable GPIO support for BYT devices where instead of the PMIC the SoC is used for backlight control. Reviewed-by:

We use the global device inode, shared amongst all files, and not the user's device filp to provide the backing storage for the mmap. The vma->vm_file provides a redundant reference that breaks existing expected behaviour that closing the user's device fd will release the resources bound to it, if a mmap persists. (Even without the vma->vm_file, the mmap will persist past the user's fd as the storage is bound to the device, i.e. our reference is on the object not file.)
