Currently we've separate detailed dram settings for all sun7i boards, this moves them over to using auto dram configuration so that we can get rid of all the per board dram_foo.c files. This has been tested on a A20-Olinuxino-Lime, A20-Olinuxino_MICRO, Bananapi, Bananapro, Cubieboard2, Cubietruck, Mele_M3 and a Linksprite_pcDuino3. Signed-off-by:

The qt840a is one of the many tv-boxes using the "i12" A20 pcb, but it populates only one of the 2 places for a 16 bit dram ic, thus reducing the buswidth to 16 bits, and the amount of ram to 512M, which is why we had a separate config for it. This commit switches the generic i12-tvbox_defconfig over to DRAM autoconfiguration, so that it will work with the qt840a too, and drops the qt840a specific config, like we've done with other memory-amount specific configs before. Tested on a generic i12-tvbox with 32 bit bus-width / 1G RAM, and on a qt840a with 16 bit bus-width / 512M RAM. Signed-off-by:

The DDR PHY training function, ddrphy_prepare_training() would not work if compiled with GCC 4.9. The struct ddrphy (arch/arm/include/asm/arch-uniphier/ddrphy-regs.h) is specified with __packed because it represents a hardware register mapping, but it turned out to cause a problem on GCC 4.9. If -mno-unaligned-access is specified (yes, it is in arch/arm/cpu/armv7/config.mk), GCC 4.9 is aware of the __attribute__((packed)) and generates extra instructions to perform the memory access in a way that does not cause unaligned access. (Actually it is not need here because the register base, the first argument of the ddrphy_prepare_training(), is always given with a 4-byte aligned address.) Anyway, as a result, readl() / writel() is divided into byte-wise accesses. The problem is that this hardware only accepts 4-byte register access. Byte-wise accesses lead to unexpected behavior. There are some options to avoid this problem. [1] Remove -mno-unaligned-access [2] Add __aligned(4) along with __packed to struct ddrphy [3] Remove __packed from struct ddrphy [1] solves the problem for ARMv7, but it does not for pre-ARMv6 and ARMv6-M architectures where -mno-unaligned-access is default. So, [1] does not seem reasonable in terms of code portability. Both [2] and [3] work well, but [2] seems too much. All the members of struct ddrphy have the u32 type. No padding would be inserted even if __packed is dropped. Signed-off-by:

Testing has shown that on sun4i the display backend engine does not have deep enough fifo-s causing flickering / tearing in full-hd mode due to fifo underruns. On sun4i use the display frontend engine to do the dma from memory, as the frontend does have deep enough fifo-s. As added advantage of this is that it results in much better memory bandwidth as it reduces the amount of dram bank switches, for more details see: http://ssvb.github.io/2014/11/11/revisiting-fullhd-x11-desktop-performance-of-the-allwinner-a10.html Note that this changes the pipeline searched for in the simplefb node, we can get away with doing this now, since no kernel has yet shipped with simplefb dtb nodes, and I will make sure to get a simplefb node with the new pipeline into 3.19 before it ships.

Instead of using the internal 'tx_clk' clock source, it is also possible to use the pixel clock signal from the parallel LCD interface ('pclk') as the reference clock for PLL. The 'tx_clk' clock speed may be different on different boards/devices (the allowed range is 8MHz - 30MHz). Which is not very convenient, especially considering the need to know the exact 'tx_clk' clock speed. This clock speed may be difficult to identify without having device schematics and/or accurate documentation/sources every time. Using 'pclk' is free from all these problems.

SSD2828 can take pixel data coming from a parallel LCD interface and translate it on the fly into MIPI DSI interface for driving a MIPI compatible TFT display. SSD2828 is configured over SPI interface, which may or may not have MISO pin wired up on some hardware. So a write-only SPI mode also has to be supported. The SSD2828 support code is implemented as a utility function and needs to be called from real display drivers, which are responsible for driving parallel LCD hardware in front of the video pipeline. The usage instructions are provided as comments in the header file. Signed-off-by:

The file, originally named "include/video/mipi_display.h", is taken from linux 3.18 (commit b2776bf7149bddd1f4161f14f79520f17fc1d71d). It provides MIPI DSI constants for DCS commands, which are needed to implement support for SSD2828 in u-boot. Signed-off-by:

And also add Kconfig option for selecting ELDO3 voltage. The reason for having this option is that the Android kernel sets ELDO3 to 1.2V when powering up LCD in the case if 'lcd_if' configuration variable is set to 6 (LCD_IF_EXT_DSI) in the FEX file. Most likely to supply power for a SSD2828 chip. However on the MSI Primo81 tablet, which is using this particular 'lcd_if = 6' setup for LCD, setting the ELDO3 voltage appears to be unnecessary and it works regardless. Having no schematics of this tablet, I can only guess that 1.2V is supplied to SSD2828 in some other way. Signed-off-by:
