2020-09-09ARM: dts: stm32: Adjust PLL4 settings on AV96 againMarek Vasut
PLL4Q is supplying both FDCAN and LTDC. In case HDMI is in use, the 50 MHz generated from PLL4Q cannot be divided well enough to produce accurate clock for HDMI pixel clock. Adjust it to generate 74.25 MHz instead. The PLL4P/PLL4R are generating 99 MHz instead of 100 MHz, which is in tolerance for the SDMMC.

2020-07-07ARM: dts: stm32mp1: use OPP information for PLL1 settings in SPLPatrick Delaunay
This patch allows to switch the CPU frequency to 800MHz on the ST Microelectronics board (DK1/DK2 and EV1) or dh electronics SOM using the STM32MP15x SOC and when it is supported by the HW (for STM32MP15xD and STM32MP15xF).

2020-05-28ARM: stm32: Hog GPIO PF7 high on DHCOR to unlock SPI NOR nWPMarek Vasut
The SPI NOR nWP line is connected to GPIO PF7 on the SoM, pull the GPIO line high by default to clear SPI NOR WP.

2020-05-14ARM: dts: stm32: Synchronize DDR setttings on DH SoMsMarek Vasut
Add custom DDR DRAM settings for the DHCOR and DHCOM SoMs and put them into use by the board file instead of the default ones. These new DRAM settings are a better fit for the SoMs. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Patrick Delaunay <patrick.delaunay@st.com> Cc: Patrice Chotard <patrice.chotard@st.com> Reviewed-by: Patrick Delaunay <patrick.delaunay@st.com>
2020-05-14ARM: stm32: Implement DDR3 coding on DHCOR SoMMarek Vasut
The DHCOR board does exist in multiple variants with different DDR3 DRAM sizes. To cater for all of them, implement DDR3 code handling. There are two GPIOs which code the DRAM size populated on the SoM, read them out and use the value to pick the correct DDR3 config.

2020-04-24ARM: dts: stm32: Split AV96 into DHCOR SoM and AV96 boardMarek Vasut
The AV96 is in fact an assembly of DH Electronics DHCOR SoM on top of an AV96 reference board. Split the DTs to reflect that and make sure to DHCOR SoM can be reused on other boards easily. It is also highly recommended to configure the board for the DHCOM make stm32mp15_dhcom_basic_defconfig make DEVICE_TREE=stm32mp15xx-dhcor-avenger96 as that permits reusing the board code for the DH components, like accessing and reading out the ethernet MAC from EEPROM.
