2017-10-08	ARM: DTS: stm32: add SDMMC support fo stm32h743-eval	Patrice Chotard
	Add pinctrl and sdmmc nodes to add MMC support for STM32H743 evaluation board. Evaluation board needs a second pinctrl node "pinctrl_sdmmc1_level_shifter" to drive a level shifter on MMC bus. Signed-off-by: Patrice Chotard <patrice.chotard@st.com>
2017-09-22	ARM: DTS: stm32: adapt stm32h7 dts files for U-boot	Patrice Chotard
	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.
