OMAPDSS: panel-sony-acx565akm: Export OF module alias information

2015-09-24T11:36:28Z

Drivers needs to export the OF id table and this be built into the module or udev won't have the necessary information to autoload the driver module when the device is registered via OF. Signed-off-by: Javier Martinez Canillas Signed-off-by: Tomi Valkeinen

fbdev: omap2: connector-dvi: use of_get_i2c_adapter_by_node interface

2015-09-24T11:35:37Z

This change is needed to properly lock I2C bus driver, which serves DDC. Prior to this change i2c_put_adapter() is misused, which may lead to an overflow over zero of I2C bus driver user counter. Signed-off-by: Vladimir Zapolskiy Signed-off-by: Tomi Valkeinen

video: fbdev: Drop owner assignment from platform_driver

2015-08-20T09:03:53Z

platform_driver does not need to set an owner because platform_driver_register() will set it. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Tomi Valkeinen

fbdev: omap2: improve usage of gpiod API

2015-06-03T09:41:53Z

Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Also make use of gpiod_get*_optional where applicable. Apart from simplification of the affected drivers this is another step towards making the flags argument to gpiod_get*() mandatory.

OMAPDSS: DISPC: remove OMAPDSS_DRIVE_SIG_OPPOSITE_EDGES

2015-02-26T10:15:11Z

DISPC can drive data lines either on rising or falling pixel clock edge, which can be configured by the user. Sync lines can also be driven on rising or falling pixel clock edge, but additionally the HW can be configured to drive the sync lines on opposite clock edge from the data lines. This opposite edge setting does not make any sense, as the same effect can be achieved by just setting the sync lines to be driven on the other edge compared to the data lines. It feels like some kind of backward compatibility option, even if all DSS versions seem to have the same implementation. To simplify the code and configuration of the signals, and to make the dispc timings more compatible with what is used on other platforms, let's just remove the whole opposite-edge support. The drivers that used OMAPDSS_DRIVE_SIG_OPPOSITE_EDGES setting are changed so that they use the opposite setting from the data edge. Signed-off-by: Tomi Valkeinen

OMAPDSS: TFP410: fix input sync signals

2015-02-26T10:15:11Z

TFP410 requires that DE is active high and the data and syncs are driven on rising pixel clock edge. However, at the moment the driver doesn't request such syncs, and the end result is that the sync settings depend on default values, which are not right in all cases. Set the sync values explicitly.

OMAPDSS: encoder-tpd12s015: Fix race issue with LS_OE

2015-02-04T10:32:04Z

A race issue has been observed with the encoder-tpd12s015 driver, which leads to errors when trying to read EDID. This has only now been observed, as OMAP4 and OMAP5 boards used SoC's GPIOs for LS_OE GPIO. On dra7-evm boards, the LS_OE is behind a i2c controlled GPIO expander, which increases the time to set the LS_OE. This patch simplifies the handling of the LS_OE gpio in the driver by removing the interrupt handling totally. The only time we actually need to enable LS_OE is when we are reading the EDID, and thus we can just set and clear the LS_OE gpio inside the read_edid() function. This also has the additional benefit of very slightly decreasing the power consumption. Signed-off-by: Tomi Valkeinen

fbdev: omap2: Fix typo in tvc_probe_pdata

2015-01-13T11:27:08Z

Assigning ddata->invert_polarity to itself is not very useful; the context suggests that the right-hand side should have been pdata->invert_polarity. Signed-off-by: Rasmus Villemoes Signed-off-by: Tomi Valkeinen

opa362 is amplifier for video and can be connected to the tvout pads of the OMAP3. It has one gpio control for enable/disable of the output (high impedance). Signed-off-by: H. Nikolaus Schaller Signed-off-by: Marek Belisko Signed-off-by: Tomi Valkeinen

Merge tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core update from Greg KH: "Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes.
