2017-06-07rockchip: video: rk3399: add HDMI TX support on the RK3399Philipp Tomsich
This commit enables the RK3399 HDMI TX, which is very similar to the one found on the RK3288. As requested by Simon, this splits the HDMI driver into a SOC-specific portion (rk3399_hdmi.c, rk3288_hdmi.c) and a common portion (rk_hdmi.c). Note that the I2C communication for reading the EDID works well with the default settings, but does not with the alternate settings used on the RK3288... this configuration aspect is reflected by the driverdata for the RK3399 driver. Having some sort of DTS-based configuration for the regulator dependencies would be nice for the future, but for now we simply use lists of regulator names (also via driverdata) that we probe.

2017-06-07rockchip: video: split RK3288-specific part off from rk_hdmiPhilipp Tomsich
To prepare for the addition of RK3399 HDMI support, the HDMI driver is refactored and broken into a chip-specific and a generic part. This change adds the internal interfaces, makes common/reusable functions externally visible and splits the RK3288 driver into a separate file. For the probing of regulators, we reuse the infrastructure created during the VOP refactoring... i.e. we simply call into the helper function defined for the VOP.

2017-06-07rockchip: video: refactor rk_vop and split RK3288-specific code offPhilipp Tomsich
To prepare for adding the RK3399 VOP driver (which shares most of its registers and config logic with the RK3228 VOP), this change refactors the driver and splits the RK3288-specific driver off. The changes in detail are: - introduces a data-structure for chip-specific drivers to register features/callbacks with the common driver: at this time, this is limited to a callback for setting the pin polarities (between the VOP and the encoder modules) and a flag to signal 10bit RGB capability - refactors the probing of regulators into a helper function that can take a list of regulator names to probe and autoset - moves the priv data-structure into a (common) header file to be used by the chip-specific drivers to provide base addresses to the common driver - uses a callback into the chip-specific driver to set pin polarities (replacing the direct register accesses previously used) - splits enabling the output (towards an encoder) into a separate help function withint the common driver Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Reviewed-by: Simon Glass <sjg@chromium.org>

Signed-off-by: Simon Glass <sjg@chromium.org>
2017-06-01dm: Fix up inclusion of common.hSimon Glass
It is good practice to include common.h as the first header. This ensures that required features like the DECLARE_GLOBAL_DATA_PTR macro, configuration options and common types are available. Fix up some files which currently don't do this. This is necessary because driver model will soon start using global data and configuration in the dm/read.h header file, included via dm.h. The gd->fdt_blob value will be used to access the device tree and CONFIG options will be used to determine whether to support inline functions in the header file.

2017-06-01dm: Rename dev_addr..() functionsSimon Glass
These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.
