2017-11-29clk: clk_stm32fx: add clock configuration for mmc usagePatrice Chotard
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.

2017-11-29dm: misc: bind STM32F4/F7 clock from rcc MFD driverPatrice Chotard
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.

Several drivers check ->chipsize to see if the third row address cycle is needed. Instead of embedding magic sizes such as 32MB, 128MB in drivers, introduce a new flag NAND_ROW_ADDR_3 for clean-up. Since nand_scan_ident() knows well about the device, it can handle this properly. The flag is set if the row address bit width is greater than 16. Delete comments such as "One more address cycle for ..." because intention is now clear enough from the code.

2017-11-29mtd: nand: add generic helpers to check, match, maximize ECC settingsMasahiro Yamada
Driver are responsible for setting up ECC parameters correctly. Those include: - Check if ECC parameters specified (usually by DT) are valid - Meet the chip's ECC requirement - Maximize ECC strength if NAND_ECC_MAXIMIZE flag is set The logic can be generalized by factoring out common code. This commit adds 3 helpers to the NAND framework: nand_check_ecc_caps - Check if preset step_size and strength are valid nand_match_ecc_req - Match the chip's requirement nand_maximize_ecc - Maximize the ECC strength To use the helpers above, a driver needs to provide: - Data array of supported ECC step size and strength - A hook that calculates ECC bytes from the combination of step_size and strength.

2017-11-29mtd: nand: automate NAND timings selectionBoris Brezillon
The NAND framework provides several helpers to query timing modes supported by a NAND chip, but this implies that all NAND controller drivers have to implement the same timings selection dance. Also currently NAND devices can be resetted at arbitrary places which also resets the timing for ONFI chips to timing mode 0. Provide a common logic to select the best timings based on ONFI or ->onfi_timing_mode_default information. Hook this into nand_reset() to make sure the new timing is applied each time during a reset.
