2020-07-28ARM: dts: stm32mp1: DT alignment with Linux kernel v5.8-rc1Patrick Delaunay
DT alignment with Linux kernel v5.8-rc1 for the STM32MP15x soc device tree files and the STMicroelectronics boards device tree files. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com> Reviewed-by: Patrice Chotard <patrice.chotard@st.com>
2020-07-07ARM: dts: stm32: add cpufreq support on stm32mp15xPatrick Delaunay
This commit adds cpufreq support on stm32mp15x SOC. STM32 cpufreq uses operating points V2 bindings (no legacy). Nvmem cells have to be used to know the chip version and then which OPPs are available. Note that STM32 cpufreq driver is mainly based on "cpufreq-dt" driver.

2020-06-16dts: ARM: stm32mp15: add OP-TEE node in u-boot DTSIEtienne Carriere
Add OP-TEE firmware node in stm32mp15 U-Boot DTSI. This node is needed since commit [1] that changed U-Boot/stm32mp15 to detect OP-TEE availability by probing the resource instead of relying on U-Boot configuration. The software sequence implemented by [1] is fine but U-Boot DTS/DTSI files were not updated accordingly since, hence OP-TEE presence is never detected by U-Boot, preventing Linux kernel from using OP-TEE resources. For consistency and to synchronize stm32mp15 DTSI files (excluding U-Boot specific DTSI files) with the Linux kernel ones, this change also moves the OP-TEE reserved memory nodes from board generic DTSI files to U-Boot specific board DTSI files.

2020-05-14board: stm32mp1: reserve memory for OP-TEE in device treePatrick Delaunay
Add reserve memory for OP-TEE in U-Boot and in kernel device tree: - no more reduce the DDR size in "memory" node: CONFIG_SYS_MEM_TOP_HIDE is no more used - U-Boot device-tree defines the needed "reserved-memory" for OP-TEE and U-Boot should not use this reserved memory: board_get_usable_ram_top use lmb lib to found the first free region, the not reserved memory, enough to relocate U-Boot: the needed size of U-Boot is estimated with gd->mon_len + CONFIG_SYS_MALLOC_LEN. - the optee node ("optee@...": firmware with compatible "linaro,optee-tz") and the associated "reserved-memory" are deactivated in kernel device tree when OP-TEE is not detected by U-Boot to prevent kernel issue (memory is reserved but not used, optee driver probe failed).

2020-03-24ARM: dts: stm32mp1: DT alignment with Linux 5.6-rc1Patrick Delaunay
This commit manages diversity for STM32M15x SOCs with: - dedicated files to support all STM32MP15 SOCs family. The differences between those SOCs are: -STM32MP151 [1]: common file. -STM32MP153 [2]: STM32MP151 + CANs + a second CortexA7-CPU. -STM32MP157 [3]: STM32MP153 + DSI + GPU. - new files to manage security diversity on STM32MP15x SOCs. On STM32MP15xY, "Y" gives information: -Y = A means no cryp IP and no secure boot. -Y = C means cryp IP + secure boot. - stm32mp157 pinctrl files to better manage package diversity.
