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

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