2016-06-19clk: convert API to match reset/mailbox styleStephen Warren
The following changes are made to the clock API: * The concept of "clocks" and "peripheral clocks" are unified; each clock provider now implements a single set of clocks. This provides a simpler conceptual interface to clients, and better aligns with device tree clock bindings. * Clocks are now identified with a single "struct clk", rather than requiring clients to store the clock provider device and clock identity values separately. For simple clock consumers, this isolates clients from internal details of the clock API. * clk.h is split so it only contains the client/consumer API, whereas clk-uclass.h contains the provider API. This aligns with the recently added reset and mailbox APIs. * clk_ops .of_xlate(), .request(), and .free() are added so providers can customize these operations if needed. This also aligns with the recently added reset and mailbox APIs. * clk_disable() is added. * All users of the current clock APIs are updated. * Sandbox clock tests are updated to exercise clock lookup via DT, and clock enable/disable. * rkclk_get_clk() is removed and replaced with standard APIs. Buildman shows no clock-related errors for any board for which buildman can download a toolchain. test/py passes for sandbox (which invokes the dm clk test amongst others).

2016-06-13arc: Update data accessors with use of memory barriersAlexey Brodkin
Memory barriers are proven to be a requirement for both compiler and real hardware to properly serialize access to critical data. For example if CPU or data bus it uses may do reordering of data accesses absence of memory barriers might easily lead to very subtle and hard to debug data corruptions. This implementation was heavily borrowed from up to date Linux kernel. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2016-06-13arc/cache: Flush & invalidate all caches right before enabling IOCAlexey Brodkin
According to ARC HS databook it is required to flush and disable caches prior programming IOC registers. Otherwise ongoing coherent memory operations may not observe the coherency protocols as expected. But since in ARC HS v2.1 there's no way to disable SLC (AKA L2 cache) we're doing our best flushing and invalidating it. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2016-06-13arc/cache: really do invalidate_dcache_all() even if IOC existsAlexey Brodkin
invalidate_dcache_all() could be used in different use-cases and what is especially important most of those cases won't be related to DMAed data to or from peripherals, i.e. we'll be doing invalidation of data used purely by CPU cores. Given that IOC engine only snoops data that goes through DMA we need to care ourselves about data used only by CPU cores and so remove dependency on IOC from invalidate_dcache_all() and always do real invalidation.

2016-06-12x86: Probe pinctrl driver in cpu_init_r()Bin Meng
At present pinctrl driver gets probed in ich6_gpio driver's probe routine, which has two issues: - Pin's PADs only gets configured when GPIO driver is probed, which is not done by default. This leaves the board in a partially functional state as we must initialize PADs correctly to get perepherals fully working. - The probe routine of pinctrl driver is called multiple times, as normally there are multiple GPIO controllers. It should really be called just once. Move the call to syscon_get_by_driver_data() from ich6_gpio driver to cpu_init_r().

2016-06-12x86: baytrail: Configure card detect pin of the SD controllerBin Meng
As of today, the latest version FSP (gold4) for BayTrail misses the PAD configuration of the SD controller's Card Detect signal. The default PAD value for the CD pin sets the pin to work in GPIO mode, which causes card detect status cannot be reflected by the Present State register in the SD controller (bit 16 & bit 18 are always zero). Add a configuration for this pin in the pinctrl node. Note I've checked the PAD configuration for all the pins in all the 3 controllers (eMMC/SDIO/SD). Only this SDMMC3_CD_B pin does not get initialized to correct mode by FSP. With fsp,emmc-boot-mode set to 2 (eMMC 4.1), eMMC pins are initialized to func 1, but if we set fsp,emmc-boot-mode to 1 (auto), those pins are initialized to func 3 which is correct according to datasheet.

2016-06-12x86: baytrail: Change fsp, emmc-boot-mode to "auto"Bin Meng
At present all BayTrail boards configure fsp,emmc-boot-mode to 2, which means "eMMC 4.1" per FSP documentation. However, eMMC 4.1 only shows up on some early stepping silicon of BayTrail SoC. Newer stepping SoC integrates an eMMC 4.5 controller. Intel FSP provides a config option fsp,emmc-boot-mode which tells FSP which eMMC controller it initializes. Instead of hardcoded to 2, now we change it to 1 which means "auto". With this change, MinnowMax board (with a D0 stepping BayTrail SoC) can see the eMMC 4.5 controller at PCI address 00.17.00 via U-Boot 'pci' command.

2016-06-10sunxi: Downclock AHB1 to 100MHz on Allwinner A64Siarhei Siamashka
Currently the AHB1 clock speed is configured as 200MHz by the SPL, but this causes a subtle and hard to reproduce data corruption in SRAM C (for example, this can't be easily detected with a trivial memset/memcmp test). For what it's worth, the Allwinner's BSP configures AHB1 as 200MHz, as can be verified by running the devmem2 tool in the system running the Allwinner's kernel 3.10.x: 0x1C20028: PLL_PERIPH0_CTRL_REG = 0x90041811 0x1C20054: AHB1_APB1_CFG_REG = 0x3180 0x1C20058: APB2_CFG_REG = 0x1000000 0x1C2005C: AHB2_CFG_REG = 0x1 However the FEL mode uses more conservative settings (100MHz for AHB1): 0x1C20028: PLL_PERIPH0_CTRL_REG = 0x90041811 0x1C20054: AHB1_APB1_CFG_REG = 0x3190 0x1C20058: APB2_CFG_REG = 0x1000000 0x1C2005C: AHB2_CFG_REG = 0x0 It is yet to be confirmed whether faster AHB1/AHB2 clock settings can be used safely if we initialize the AXP803 PMIC instead of using reset defaults. But in order to resolve the data corruption problem right now, it's best to downclock AHB1 to a safe level. Note that this issue only affects the SPL, which is not fully supported on Allwinner A64 yet and it should not affect the boot0 usage (unless somebody can confirm SRAM C corruption with the boot0 too).
