drm/bridge: analogix_dp: Add analogix_dp_psr_supported

2016-10-04T06:23:16+00:00

So users know whether PSR should be enabled or not.

drm/bridge: analogix_dp: add the PSR function support

2016-08-23T15:44:33+00:00

The full name of PSR is Panel Self Refresh, panel device could refresh
itself with the hardware framebuffer in panel, this would make lots of
sense to save the power consumption.

This patch have exported two symbols for platform driver to implement
the PSR function in hardware side:
- analogix_dp_active_psr()
- analogix_dp_inactive_psr()

drm/bridge: analogix_dp: passing the connector as an argument in .get_modes()

2016-07-05T13:53:38+00:00

It's better to pass the connector to platform driver in .get_modes()
callback, just like what the .get_modes() helper function designed.

drm/rockchip: analogix_dp: add rk3399 eDP support

2016-07-05T13:53:31+00:00

RK3399 and RK3288 shared the same eDP IP controller, only some light
difference with VOP configure and GRF configure.

drm/bridge: analogix_dp: some rockchip chips need to flip REF_CLK bit setting

2016-07-05T01:16:40+00:00

As vendor document indicate, when REF_CLK bit set 0, then DP
phy's REF_CLK should switch to 24M source clock.

But due to IC PHY layout mistaken, some chips need to flip this
bit(like RK3288), and unfortunately they didn't indicate in the
DP version register. That's why we have to make this little hack.

sclk_edp in platform driver.

drm: bridge: analogix/dp: split exynos dp driver to bridge directory

2016-04-05T02:11:48+00:00

Split the dp core driver from exynos directory to bridge directory,
and rename the core driver to analogix_dp_*, rename the platform
code to exynos_dp.

Beside the new analogix_dp driver would export six hooks.
"analogix_dp_bind()" and "analogix_dp_unbind()"
"analogix_dp_suspned()" and "analogix_dp_resume()"
"analogix_dp_detect()" and "analogix_dp_get_modes()"

The bind/unbind symbols is used for analogix platform driver to connect
with analogix_dp core driver. And the detect/get_modes is used for analogix
platform driver to init the connector.

They reason why connector need register in helper driver is rockchip drm
haven't implement the atomic API, but Exynos drm have implement it, so
there would need two different connector helper functions, that's why we
leave the connector register in helper driver.

Merge branch 'drm-dwhdmi-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into drm-next

2015-08-27T03:01:57+00:00

Here are some development updates for the Synopsis Designware HDMI driver,
which clean up some of the code, and start preparing to add audio support
to the driver.  This series of patches are based on a couple of dependent
commits from the ALSA tree.

Briefly, the updates are:
- move comments which should have moved with the phy values to the IMX
  part of the driver.
- clean up the phy configuration: to all lookups before starting to
  program the phy.
- clean up the HDMI clock regenerator code
- use the drm_hdmi_avi_infoframe_from_display_mode() helper which allows
  the code to be subsequently simplified
- remove the unused 'regmap' pointer in struct dw_hdmi
- use the bridge drm device rather than the connector (we're the bridge
  code)
- remove private hsync/vsync/interlaced flags, getting them from the
  DRM mode structure instead.
- implement interface functions to support audio - setting the audio
  sample rate, and enabling the audio clocks.
- removal of broken pixel repetition support
- cleanup DVI vs HDMI sink handling
- enable audio only if connected device supports audio
- avoid double-enabling bridge in the sink path (once in mode_set, and
  again in commit)
- rename mis-named dw_hdmi_phy_enable_power()
- fix bridge enable/disable handing, so a plug-in event doesn't
  reconfigure the bridge if DRM has disabled the output
- fix from Vladimir Zapolskiy for the I2CM_ADDRESS macro name

These are primerily preparitory patches for the AHB audio driver and
the I2S audio driver (from Rockchip) for this IP.

drm: bridge/dw_hdmi: introduce interfaces to enable and disable audio

2015-08-18T10:27:15+00:00

iMX6 devices suffer from an errata (ERR005174) where the audio FIFO can
be emptied while it is partially full, resulting in misalignment of the
audio samples.

To prevent this, the errata workaround recommends writing N as zero
until the audio FIFO has been loaded by DMA.  Writing N=0 prevents the
HDMI bridge from reading from the audio FIFO, effectively disabling
audio.

This means we need to provide the audio driver with a pair of functions
to enable/disable audio.  These are dw_hdmi_audio_enable() and
dw_hdmi_audio_disable().

A spinlock is introduced to ensure that setting the CTS/N values can't
race, ensuring that the audio driver calling the enable/disable
functions (which are called in an atomic context) can't race with a
modeset.
