drm/i2c: remove unneeded -Iinclude/drm compiler flag

2017-05-18T05:13:04+00:00

With the include directives under include/drm/ fixed, this flag is no longer needed. Signed-off-by: Masahiro Yamada Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1493009447-31524-21-git-send-email-yamada.masahiro@socionext.com

drm/i2c: tda998x: fix spelling mistake

drm/i2c: tda998x: allow sharing of the CEC device accesses

2016-11-18T00:00:40+00:00

cec_read() is non-atomic in the presence of other I2C bus transactions to the same device. This presents a problem when we add support for the TDA9950 CEC engine part - both drivers can be trying to access the device. Avoid the inherent problems by switching to i2c_transfer() instead, which allows us to perform more than one bus transaction atomically. As this means we will be using I2C transactions rather than SMBUS, we have to check that the host supports I2C functionality.

drm/i2c: tda998x: allow interrupt to be shared

2016-11-18T00:00:40+00:00

Some TDA998x contain several different I2C devices - there is the HDMI encoder, and there is a TDA9950 CEC engine. These two share the same interrupt signal. In order to allow a driver for the CEC engine to work, we need to be able to share the interrupt with the CEC driver, so convert the handler and registration to allow this to happen.

drm/i2c: tda998x: power down pre-filter and color conversion

2016-11-18T00:00:40+00:00

Disabling the pre-filter block of the TDA998x saves 40mW and the colour conversion block saves 15mW. As we always disable these two blocks, we can power these sections of the chip down to save 55mW of unnecessary power consumption.

drm/i2c: tda998x: switch to boolean is_on

2016-11-18T00:00:40+00:00

Rather than storing the DPMS mode (which will always be on or off) use a boolean to store this instead. Tested-by: Robin Murphy Tested-by: Jon Medhurst Acked-by: Jon Medhurst Tested-by: Jyri Sarha Signed-off-by: Russell King

drm/i2c: tda998x: remove complexity from tda998x_audio_get_eld()

2016-11-18T00:00:40+00:00

tda998x_audio_get_eld() is needlessly complex - the connector associated with the encoder is always our own priv->connector. Remove this complexity, but ensure that there are no races when copying out the ELD. Tested-by: Jon Medhurst Acked-by: Jon Medhurst Tested-by: Jyri Sarha Signed-off-by: Russell King

drm/i2c: tda998x: group audio functions together
