2017-10-26ARM: dts: mvebu: pl310-cache disable double-linefillYan Markman
Under heavy system stress mvebu SoC using Cortex A9 sporadically encountered instability issues. The "double linefill" feature of L2 cache was identified as causing dependency between read and write which lead to the deadlock. Especially, it was the cause of deadlock seen under heavy PCIe traffic, as this dependency violates PCIE overtaking rule.

In order to optimize the L2 cache performance, this commit adjusts the configuration of the L2 on the Cortex-A9 based Marvell EBU processors (Armada 375, 38x and 39x), using the appropriate DT properties. We enable double linefill, incr double linefill, data prefetch and disable double linefill on wrap. This matches the configuration that was fine tuned in the Marvell BSP.

2015-05-01ARM: mvebu: Fix the main PLL frequency on Armada 375, 38x and 39x SoCsGregory CLEMENT
Whereas for Armada 370 and XP the main PLL frequency was 2GHz for the Armada 375, 38x and 39x, the frequency is 1GHz. When writing support for these last SoCs, there was no official value for the PLL. Now that we have it, this patch fixes it in the device tree. This value is currently only used by the NAND driver for the setting the NAND timing. Fortunately it is not actually used: all the mainline board with a NAND flash comes with a NAND device tree node using the "marvell,nand-keep-config" property. With this property the timings are not modified in the kernel driver and are kept from the bootloader.

2014-07-23ARM: mvebu: Add missing MDIO clock in Armada 375Ezequiel Garcia
In Armada 375 SoCs, the MDIO is handled by a separate orion-mdio driver, despite the register is contained within the "LMS" block of the network controller. Therefore we need to add the clock to the MDIO devicetree to prevent the controller from being accesed with its clock gated. This is needed, for instance, to be able to load the MDIO driver before the network driver.

2014-04-26ARM: mvebu: use clocks property for serial portsThomas Petazzoni
Back when the Armada 370 and Armada XP initial support was introduced, the only way to pass the clock frequency to the of_serial driver was through a clock-frequency Device Tree property. Thanks to 0bbeb3c3e84bc963d1c66661e082d207023b0e5c ('of serial port driver - add clk_get_rate() support'), it is possible to use the standard 'clocks' DT property to reference the clock used for a particular UART controller. This clock is then used by the of_serial driver to retrieve the clock rate. This commit modifies the SoC-level Device Tree files of Armada 370, Armada XP, Armada 375 and Armada 38x to use this possibility. Since there is no gatable clock for the UART controllers, we simply reference the TCLK, which is the main SoC clock for the peripherals.
