* ARM: PSCI: use only r0 and r3 in psci_get_cpu_stack_top()Chen-Yu Tsai2016-06-20-9/+9
| | | | | | | | | | | For psci_get_cpu_stack_top() to be usable in C code, it must adhere to the ARM calling conventions. Since it could be called when the stack is still unavailable, and the entry code to linux also expects r1 and r2 to remain unchanged, stick to r0 and r3.

| * clk: convert API to match reset/mailbox styleStephen Warren2016-06-19-55/+204
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* | ARM: uniphier: reserve memory for DRAM PHY training on PH1-LD20Masahiro Yamada2016-06-20-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DRAM PHY layer on PH1-LD20 is able to calibrate PHY parameters periodically. This compensates for the voltage and temperature deviation and improves the PHY parameter adjustment. Instead, it requires 64 byte scratch memory in each DRAM channel for the dynamic training. The memory regions must be reserved in DT before jumping to the kernel. The scratch area can be anywhere in each DRAM channel, but the DRAM init code in SPL currently assigns it at the end of each channel. So, it makes sense to reserve the regions on run-time by U-Boot instead of statically embedding it in the DT in Linux. Anyway, a boot-loader should know much more about memory initialization than the kernel. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

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>

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).
