drm: dw-hdmi-i2s: add .get_dai_id callback for ALSA SoC

2017-06-28T19:46:39+00:00

ALSA SoC needs to know connected DAI ID for probing. It is not a big problem if device/driver was only for sound, but getting DAI ID will be difficult if device includes both Video/Sound, like HDMI. To solve this issue, this patch adds new .get_dai_id callback on hdmi_codec_ops. dw-hdmi-i2s will assume that HDMI sound will be connected to reg = <2>. Then, ALSA SoC side will recognized it as DAI 0 ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; /* HDMI Video IN */ }; port@1 { reg = <1>; /* HDMI OUT */ }; port@2 { reg = <2>; /* HDMI Sound IN */ }; }; Signed-off-by: Kuninori Morimoto Acked-by: Archit Taneja Signed-off-by: Mark Brown

drm: dw-hdmi: Fix compilation breakage by selecting REGMAP_MMIO

2017-06-12T03:35:04+00:00

The dw-hdmi driver switched to regmap-mmio, but lacks the dependency in Kconfig. This can result in compilation breakages. Fix it by selecting REGMAP_MMIO.

drm/bridge/synopsys: dw-hdmi: Use bridge->mode_valid() callback

2017-06-05T06:39:50+00:00

Now that we have a callback to check if bridge supports a given mode we can use it in Synopsys Designware HDMI bridge so that we restrict the number of probbed modes to the ones we can actually display. Also, there is no need to use mode_fixup() callback as mode_valid() will handle the mode validation. NOTE: I also had to change the pdata declaration of mode_valid custom callback so that the passed modes are const. I also changed in the platforms I found. Not even compiled it though.

drm: dw-hdmi: gate audio clock from the I2S enablement callbacks

2017-04-20T09:24:13+00:00

Currently, the audio sampler clock is enabled from dw_hdmi_setup() at step E. and is kept enabled for later use. This clock should be enabled and disabled along with the actual audio stream and not always on (that is bad for PM). Furthermore, as described by the datasheet, the I2S variant needs to gate/ungate the clock when the stream is enabled/disabled. This commit adds a parameter to hdmi_audio_enable_clk() that controls when the audio sample clock must be enabled or disabled. Then, it adds the call to this function from dw_hdmi_i2s_audio_enable() and dw_hdmi_i2s_audio_disable().

drm: dw-hdmi: add specific I2S and AHB functions for stream handling

2017-04-20T09:02:51+00:00

Currently, CTS+N is forced to zero as a workaround of the IP block for i.MX platforms. This is requested in the datasheet of the corresponding IP for AHB mode only. However, we have seen that it introduces glitches or delays when playing a sound on HDMI for I2S mode. This proves that we cannot keep the current functions for handling audio stream as-is if these contain workaround that are specific to a mode. This commit introduces two callbacks, one for each variant. dw_hdmi_setup defines the right function depending on the detected variant. Then, the exported functions dw_hdmi_audio_enable and dw_hdmi_audio_disable calls the corresponding callbacks Reviewed-by: Neil Armstrong Signed-off-by: Romain Perier Signed-off-by: Archit Taneja Link: http://patchwork.freedesktop.org/patch/msgid/20170414083113.4255-2-romain.perier@collabora.com

drm: dw-hdmi: Implement the mode_fixup drm helper

2017-04-10T09:23:10+00:00

This helper is supposed to validate or reject the modeline before it applied by the mode setting. Currently this function has been dropped, it was previously set to a dummy function that always returned true. For both cases, this means that userspace can ask for a bad modeline that will be always accepted. On some platforms, like Rockchip, the drm dw_hdmi-rockchip variant driver already implements the atomic_check drm helper, so mode_fixup cannot be handled and implemented there (as drm_atomic_helper relies on either atomic_check or mode_fixup). This commit implements this helper. It only checks that this mode is correct from the connector point of view.
