be5b96f0e4 sunxi: setup simplefb for Allwinner DE2

f6bdddc92b video: add an option for video simplefb via DT
Add an option to indicate that the video driver should setup a SimpleFB
node that passes the video framebuffer initialized by U-Boot to the
operating system kernel.

Currently only the Allwinner DE driver uses this option, and the
definition of this option in the sunxi-common.h config header is
converted to an imply of this option from CONFIG_VIDEO_SUNXI.

9b643e312d treewide: replace with error() with pr_err()
U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

  # define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux.  (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// <smpl>
@@@@
-error
+pr_err
 (...)
// </smpl>

703d885c22 dm: video: Add color ANSI escape sequence support
Note that this doesn't differentiate (due to lack of information in
video_priv) between different possible component orders for 32bpp.
But the main user at this point is efi_loader, and GOP expects xBGR
so any video drivers that this is incorrect for already have problems.
(Also, conveniently, this matches what simple-framebuffer bindings
expect for kernels that use the simple-framebuffer DT binding to
take over the bootloader display.)

72719d2f8a video: add STM32 LTDC display controller
The STM32 LTDC display controller provides a parallel digital RGB and
signals for horizontal, vertical synchronization, Pixel Clock and Data
Enable as output to interface directly to a variety of LCD and TFT panels.

The LTDC main features are:
- 24-bit RGB Parallel Pixel Output, Programmable timings & polarity for
  HSync, VSync and Data Enable.
- 2 layers with Blending, Color Keying, Window position & size,
  Dithering, Background color, Color Look-Up Table (CLUT).
- Supported layer color formats: ARGB8888, RGB888, RGB565, ARGB1555,
  ARGB4444, L8 CLUT, AL44 & AL88

This LTDC driver:
- supports: RGB parallel output with timings & polarity, 1 layer
  in RGB565.
- supports but with hard-coded configurations: blending, window
  position & size (crop), background color.
- does not support yet: rgb888, argb8888, 8-bit clut, dithering.

This LTDC driver is compatible with all stm32 platforms with the
LTDC IP and has been tested on stm32 f746-disco board.

c7430d7d5e ipu_common: Let the MX6 IPU clock be calculated in run-time
MX6Q/QP IPU operates at 264MHz and MX6DL IPU at 198MHz.

When running a SPL target, which supports multiple MX6 variants we cannot
properly setup the IPU clock frequency via CONFIG_IPUV3_CLK option as
such decision is done in build-time currently.

Remove the CONFIG_IPUV3_CLK option and let the IPU clock frequency be
configured in run-time on mx6.

ca562b630e rockchip: video: rk3399: add HDMI TX support on the RK3399
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.

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.

d46d40474a rockchip: video: refactor rk_vop and split RK3288-specific code off
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

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.

520c174b35 rockchip: video: Remove CSC initialization (HDMI)
Despite the comment in the code, CSC unit is never used. According to
the only public description of DW HDMI controller (i.MX6 manual), CSC
unit is bypassed in MC_FLOWCTRL register and then actually powered
down in MC_CLKDIS register.

1d4ed26faf video: cfb_console: fix 32-bit display on 64-bit architectures
"unsigned long" is a lousy data type when it comes to match peripheral
hardware registers with a fixed size.
Just do the obvious and match a 32-bit display format with an "u32"
data type for casting.
This fixes the logo display on 64-bit architectures, which produced
a black line on the right side of the logo with non-black backgrounds.
