2018-03-16clk: at91: add USB Host clock driverWenyou Yang

2018-02-07spl: eMMC/SD: Provide one __weak spl_boot_mode() functionLukasz Majewski
The goal of this patch is to clean up the code related to choosing SPL MMC boot mode. The spl_boot_mode() now is called only in spl_mmc_load_image() function, which is only compiled in if CONFIG_SPL_MMC_SUPPORT is enabled. To achieve the goal, all per mach/arch implementations eligible for unification has been replaced with one __weak implementation.

Refer to the commit 70f8c8316ad(PMC: add new mck function to lower rate while switching) from AT91Bootstrap. While switching to a lower clock source, we must switch the clock source first instead of last. Otherwise, we could end up with too high frequency on internal bus and peripherals. This happens on SAMA5D2 as exitting from the ROM code. Add a function pmc_mck_init_down() to allow this sequence.

2017-09-14clk: at91: utmi: Set the reference clock frequencyWenyou Yang
By default, it is assumed that the UTMI clock is generated from a 12 MHz reference clock (MAINCK). If it's not the case, the FREQ field of the SFR_UTMICKTRIM has to be updated to generate the UTMI clock in the proper way. The UTMI clock has a fixed rate of 480 MHz. In fact, there is no multiplier we can configure. The multiplier is managed internally, depending on the reference clock frequency, to achieve the target of 480 MHz.

2017-08-13spl: add hierarchical defaults for SPL_LDSCRIPTPhilipp Tomsich
With SPL_LDSCRIPT moved to Kconfig (and this being a 'string' config node), all the lingering definitions in header files will cause warnings/errors due to the redefinition of the configuration item. As we don't want to pollute the defconfig files (and values should usually be identical for entire architectures), the defaults are moved into Kconfig. Kconfig will always pick the first default that matches, so please keep these values at the end of each file (to allow any board-specific Kconfig, which will be included earlier) to override with an unconditional default setting.
