Update the driver to support the device tree and the driver model. Timings and panel parameters are now loaded from the device tree. The DM code replaces the am335x_lcdpanel structure with tilcdc_panel_info taken from the linux kernel, as well the management of additional parameters not covered in the legacy code. In addition, the am335x_lcdpanel structure contains parameters and operations that were probably a requirement of the board for which this driver was developed and which, however, were not developed in the linux kernel. All this led to rewrite th DM controller initialization code, except for the pixel clock setting that is executed in a function created in a previous patch with code taken from the legacy am335xfb_init. The patch has been tested on a custom board with u-boot 2018.11-rc2 and the following device-tree configuration: panel { compatible = "ti,tilcdc,panel"; pinctrl-names = "default"; pinctrl-0 = <&lcd_enable_pins>; enable-gpios = <&gpio0 31 0>; backlight = <&backlight>; status = "okay"; u-boot,dm-pre-reloc; panel-info { ac-bias = <255>; ac-bias-intrpt = <0>; dma-burst-sz = <16>; bpp = <16>; fdd = <0x80>; sync-edge = <0>; sync-ctrl = <1>; raster-order = <0>; fifo-th = <0>; }; display-timings { native-mode = <&timing0>; timing0: 800x480 { hactive = <800>; vactive = <480>; hback-porch = <46>; hfront-porch = <210>; hsync-len = <20>; vback-porch = <23>; vfront-porch = <22>; vsync-len = <10>; clock-frequency = <33000000>; hsync-active = <0>; vsync-active = <0>; }; }; }; Signed-off-by: Dario Binacchi <dariobin@libero.it> Tested-by: Dario Binacchi <dariobin@libero.it>

pixels and is the nominal height of a character. Note that fonts

are commonly measured in 'points', being 1/72 inch (about 3.52mm).

U-Boot to calculate the correct font size.
