2017-12-11ARC: clk: introduce HSDK CGU clock driverEugeniy Paltsev
Synopsys HSDK clock controller generates and supplies clocks to various controllers and peripherals within the SoC. Each clock has assigned identifier and client device tree nodes can use this identifier to specify the clock which they consume. All available clocks are defined as preprocessor macros in the dt-bindings/clock/snps,hsdk-cgu.h header and can be used in device tree sources.

MMC block needs 48Mhz source clock, for that we choose to select the SAI PLL. Update also stm32_clock_get_rate() to retrieve the MMC clock source needed in MMC driver. STM32F4 uses a different RCC variant than STM32F7. For STM32F4 sdmmc clocks bit are located into dckcfgr register whereas there are located into dckcfgr2 registers on STM32F7. In both registers, bits CK48MSEL and SDMMC1SEL are located at the same position.

Like STM32H7, now STM32F4/F7 clock drivers are binded by MFD stm32_rcc driver. This also allows to add reset support to STM32F4/F7 SoCs family. As Reset driver is not part of SPL supported drivers, don't bind it in case of SPL to avoid that stm32_rcc_bind() returns an error.

2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory.
