arm64: dts: add device tree for ARM SMM-A53x2 on LogicTile Express 20MG

2015-07-08T21:44:56+00:00

Add a DTS file for the MP2 Cortex-A53 Soft Macrocell Model implemented on a LogicTile Express 20MG (V2F-1XV7) daughterboard. This is based on the version that's currently available from the ARM DTS repository [1].

Pull ARM SoC driver updates from Kevin Hilman: "Some of these are for drivers/soc, where we're now putting SoC-specific drivers these days. Some are for other driver subsystems where we have received acks from the appropriate maintainers. Some highlights: - simple-mfd: document DT bindings and misc updates - migrate mach-berlin to simple-mfd for clock, pinctrl and reset - memory: support for Tegra132 SoC - memory: introduce tegra EMC driver for scaling memory frequency - misc. updates for ARM CCI and CCN busses" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (48 commits) drivers: soc: sunxi: Introduce SoC driver to map SRAMs arm-cci: Add aliases for PMU events arm-cci: Add CCI-500 PMU support arm-cci: Sanitise CCI400 PMU driver specific code arm-cci: Abstract handling for CCI events arm-cci: Abstract out the PMU counter details arm-cci: Cleanup PMU driver code arm-cci: Do not enable CCI-400 PMU by default firmware: qcom: scm: Add HDCP Support ARM: berlin: add an ADC node for the BG2Q ARM: berlin: remove useless chip and system ctrl compatibles clk: berlin: drop direct of_iomap of nodes reg property ARM: berlin: move BG2Q clock node ARM: berlin: move BG2CD clock node ARM: berlin: move BG2 clock node clk: berlin: prepare simple-mfd conversion pinctrl: berlin: drop SoC stub provided regmap ARM: berlin: move pinctrl to simple-mfd nodes pinctrl: berlin: prepare to use regmap provided by syscon reset: berlin: drop arch_initcall initialization ...

ARM64: juno: add GPIO keys

2015-06-11T21:15:05+00:00

The Juno board has two keys connected to a PL061 GPIO block, in accordance to DDI0524B "ARM Versatile Express Juno Development Platform" revision 1.0, table 2-4 "GPIO (0) and GPIO (1) used for additional user key entry". By trial-and-error I found that these are connected to the two keys named "power" and "home" on the motherboard. Register the GPIO block and these two keys in the device tree using the PL061 GPIO driver and the generic gpio keys. - Map POWER, HOME, VOL+ and VOL- to the obvious input events. - Map RLOCK to KEY_SCREENLOCK/KEY_COFFEE unless someone can explain better what this is for. - Map the NMI button to KEY_SYSREQ as this is used like so in the SYSREQ debugging hack.

arm64: Add DT support for Juno r1 board.

2015-05-22T15:25:35+00:00

This board is based on Juno r0 with updated Cortex A5x revisions and board errata fixes. It also contains coherent ThinLinks ports on the expansion slot that allow for an AXI master on the daughter card to participate in a coherency domain. Support for SoC PCIe host bridge will be added as a separate series. Signed-off-by: Liviu Dudau Acked-by: Jon Medhurst Acked-by: Sudeep Holla

arm64: Juno: Add GICv2m support in device tree.

arm64: Juno: Add memory mapped timer node

2015-05-22T15:25:25+00:00

Juno based boards have a memory mapped timer @ 0x2a810000. This is disabled on r0 version of the board due to an SoC errata. Signed-off-by: Liviu Dudau Acked-by: Jon Medhurst Acked-by: Sudeep Holla

arm64: Juno: Fix the GIC node address label and the frequency of FAXI clock.

2015-05-22T15:25:07+00:00

During the review of the Juno DT files I've noticed that the GIC node label had two digits swapped leading to a different address being shown in the /sys/devices fs. Sudeep also pointed that public revisions of the Juno documentation list a different frequency for the FAXI system than what the one I've been using when creating the DT file. Verified with the firmware people to be the correct value in the shipped systems. Reported-by: Sudeep Holla Signed-off-by: Liviu Dudau Acked-by: Sudeep Holla Acked-by: Jon Medhurst

ARM64: juno: add sp810 support and fix sp804 clock frequency

2015-05-12T14:39:28+00:00

The clock generator in IOFPGA generates the two source clocks: 32kHz and 1MHz for the SP810 System Controller. The SP810 System Controller selects 32kHz or 1MHz as the sources for TIM_CLK[3:0], the SP804 timer clocks. The powerup default is 32kHz but the maximum of "refclk" and "timclk" is chosen by the SP810 driver. This patch adds support for SP810 system controller and also fixes the SP804 timer clock frequency. However the SP804 driver needs to be enabled on ARM64 to test this, which requires SP804 driver to be moved out of arch/arm. Fixes: 71f867ec130e ("arm64: Add Juno board device tree.")
