2018-02-23rockchip: video: rk_vop: migrate to livetreePhilipp Tomsich1-28/+57
This migrates rk_vop (the shared functions used by multiple VOP mini-drivers) to be compatible with a live tree. Unfortunately, there's (i) a lot of tree traversal needed for a VOP (as each active VOP vnode references back to the endpoints in the encoders and vice versa) to configure the connection between VOPs and encoders; (ii) the DTS binding is not too sane and one needs to walk a node's parents (the original code just assumed that the device would live 3 levels above the property linked through a phandle) until a UCLASS_DISPLAY device can be found. As part of the migration, the code for finding the enclosing display device has been changed to not assume a specific depth of nesting (i.e. we walk until we reach the root or find a matching device) and to use the newly introduced (in the same series) ofnode_get_parent() function.

2018-02-23rockchip: video: rk_hdmi: migrate to livetreePhilipp Tomsich1-1/+1
The rk_hdmi (shared functions for multiple HDMI mini-drivers) has been using devfdt_get_addr() to read the HDMI controller's IO base address. This will cause a failure with a live tree. This changes the driver to use dev_read_addr() which is safe both for flat trees and live trees.

2018-01-11am335x-fb: setup display PLLHannes Schmelzer2-4/+52
The LCDC IP-core an be feed from several clock sources, one of those is a dedicated DPLL for generating a dividable base-clock for this IP-core. The TRM specifies the maximum input frequency for the LCCD with 200 MHz, so we must not exceed this value with the PLL frequency (which can lock much higher). This patch tries every combination of multipliers and divisors of the PLL and the IP-core itself for getting as near as possible the the requested panel->pxl_clk.

2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada1-1/+1
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.

2017-09-29dm: video: Add color ANSI escape sequence supportRob Clark1-0/+94
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.)
