2022-06-17clk: Add directory for STM32 clock driversPatrick Delaunay1-2331/+0
Add a directory in drivers/clk to regroup the clock drivers for all STM32 Soc with CONFIG_ARCH_STM32 (MCUs with cortex M) or CONFIG_ARCH_STM32MP (MPUs with cortex A).

2021-11-10stm32mp15: replace CONFIG_TFABOOT when it is possiblePatrick Delaunay1-3/+1
In some part of STM32MP15 support the CONFIG_TFABOOT can be replaced by other config: CONFIG_ARMV7_PSCI and CONFIG_ARM_SMCCC. This patch also simplifies the code in cpu.c, stm32mp1_ram.c and clk_stml32mp1.c as execution of U-Boot in sysram (boot without SPL and without TFA) is not supported: the associated initialization code is present only in SPL. This cleanup patch is a preliminary step to support SPL load of OP-TEE in secure world, with SPL in secure world and U-Boot in no-secure world.

This clock is already defined in kernel device tree, stm32mp151.dtsi but not yet supported in the syscon driver: syscfg: syscon@50020000 { compatible = "st,stm32mp157-syscfg", "syscon"; reg = <0x50020000 0x400>; clocks = <&rcc SYSCFG>; }; It is safe to support this clock in U-Boot driver with RCC_MC_APB3ENSETR, Bit 11 SYSCFGEN: SYSCFG peripheral clocks enable.

This change makes stm32mp1 clock driver to get the root clocks reference from the device node in the FDT rather than fetching straight these clocks by their name.

2021-02-02common: Drop asm/global_data.h from common headerSimon Glass1-0/+1
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass1-1/+1
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>
