2015-10-22ARM: dts: fix gpio-keys wakeup-source propertySudeep Holla1-6/+6
The keyboard driver for GPIO buttons(gpio-keys) checks for one of the two boolean properties to enable gpio buttons as wakeup source: 1. "wakeup-source" or 2. the legacy "gpio-key,wakeup" However juno, ste-snowball and emev2-kzm9d dts file have a undetected "wakeup" property to indictate the wakeup source. This patch fixes it by making use of "wakeup-source" property.

2015-08-18ARM64: dts: vexpress: Use assigned-clock-parents for sp810Stephen Boyd1-0/+2
The sp810 clk driver is calling the clk consumer APIs from clk_prepare ops to change the parent to a 1 MHz fixed rate clock for each of the clocks that the driver provides. Use assigned-clock-parents for this instead of doing it in the driver to avoid using the consumer API in provider code. This also allows us to remove the usage of clk provider APIs that take a struct clk as an argument from the sp810 driver.

2015-06-12ARM64: juno: add GPIO keysLinus Walleij1-0/+61
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.

2015-05-12ARM64: juno: add sp810 support and fix sp804 clock frequencySudeep Holla1-4/+27
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.")

2015-05-11arm64: juno: Add APB registers and LEDs using sysconLinus Walleij1-0/+68
This defines the Juno "APB system registers" as a syscon device, and all the LEDs controlled by the APB system registers right below it using the syscon LEDs driver on top of syscon. Define LED0 for heartbeat, LED1 for MMC0 activity and the following four LEDs indicating CPU activity using the Linux-specific DT bindings for triggers. This is the pattern and same drivers as used on the legacy platform device trees for the ARM Integrators and the RealView PB1176.

2014-11-20arm64: Add Juno board device tree.Liviu Dudau1-0/+129
This adds support for ARM's Juno development board (rev 0). It enables most of the board peripherals: UART, I2C, USB, MMC and 100Mb ethernet. There is no support at the moment for clock setting and HDLCD driver which depends on it. Signed-off-by: Liviu Dudau <Liviu.Dudau@arm.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
