- add stm32h750i-art-pi.dtb (arch/arm/boot/dts/Makefile)
- add stm32h750i-art-pi.dts to support art-pi board
- add stm32h750i-art-pi-u-boot.dtsi to support art-pi board (u-boot)

art-pi board component:
- 8MiB qspi flash
- 16MiB spi flash
- 32MiB sdram
- ap6212 wifi&bt&fm

ARM: DTS: stm32: adapt stm32h7 dts files for U-boot

2017-09-22T11:40:03+00:00

This patch adapts stm32h743 disco and eval dts files to match
with U-boot requirements or add features wich are not yet
upstreamed on kernel side :

_ Add RCC clock driver node and update all clocks phandle
  accordingly.

  By default, on kernel side, all clocks was temporarly
  configured as a phandle to timer_clk waiting for a RCC
  clock driver to be available.
  On U-boot side, we now have a dedicated RCC clock driver, we
  can configured all clocks as phandle to this driver.

  All this binding update will be available soon in a kernel tag,
  as all the bindings have been acked by Rob Herring [1].

  [1] http://lkml.iu.edu/hypermail/linux/kernel/1704.0/00935.html

_ Align STM32H7 serial compatible string with the one which will be
  available in next kernel tag. The bindings has been acked by
  Rob Herring [2].
  This compatible string will be usefull to add stm32h7 specific
  feature for this serial driver.

  [2] https://lkml.org/lkml/2017/7/17/739

_ Add gpio compatible and aliases for stm32h743

_ Add FMC sdram node with associated new bindings value to
  manage second bank (ie bank 1).

_ Add missing HSI and CSI oscillators nodes needed
  by STM32H7 RCC clock driver.

  Clock sources could be:
	_ HSE (High Speed External)
	_ HSI (High Speed Internal)
	_ CSI (Low Power Internal)

  These clocks can be used as clocksource in some configuration.
  By default, HSE is selected as clock source.

_ Set HSE to 25Mhz for stm32h743i-disco and eval board

  By default, the external oscillator frequency is defined at
  25 Mhz in SoC stm32h743.dtsi file.
  It has been set at 125 Mhz in kernel DT temporarly waiting for
  RCC clock driver becomes available.

  As in U-boot we got a RCC clock driver, the real value of HSE
  clock can be used.

_ Add "u-boot,dm-pre-reloc" for rcc, fmc, fixed-clock, pinctrl,
  pwrcfg and gpio nodes.

rockchip: rk3368: add DRAM controller driver with DRAM initialisation

2017-08-13T15:12:33+00:00

This adds a DRAM controller driver for the RK3368 and places it in
drivers/ram/rockchip (where the other DM-enabled DRAM controller
drivers for rockchip devices should also be moved eventually).

At this stage, only the following feature-set is supported:
 - DDR3
 - 32-bit configuration (i.e. fully populated)
 - dual-rank (i.e. no auto-detection of ranks)
 - DDR3-1600K speed-bin

This driver expects to run from a TPL stage that will later return to
the RK3368 BROM.  It communicates with later stages through the
os_reg2 in the pmugrf (i.e. using the same mechanism as Rockchip's DDR
init code).

Unlike other DMC drivers for RK32xx and RK33xx parts, the required
timings are calculated within the driver based on a target frequency
and a DDR3 speed-bin (only the DDR3-1600K speed-bin is support at this
time).

The RK3368 also has the DDRC0_CON0 (DDR ch. 0, control-register 0)
register for controlling the operation of its (single-channel) DRAM
controller in the GRF block.  This provides for selecting DDR3, mobile
DDR modes, and control low-power operation.
As part of this change, DDRC0_CON0 is also added to the GRF structure
definition (at offset 0x600).

stm32f7: sdram: correct sdram configuration as per micron sdram

2017-05-08T15:57:22+00:00

Actually the sdram memory on stm32f746 discovery board is micron part
MT48LC_4M32_B2B5_6A. This patch does the modification required in the
device tree node & driver for the same.

Also we are passing here all the timing parameters in terms of clock
cycles, so no need to convert time(ns or ms) to cycles.
