2015-08-06ARM: imx6: correct i.MX6 PCIe interrupt routingLucas Stach1-4/+4
The PCIe interrupts are also routed through the GPC. This has been missed from the conversion to stacked IRQ domains as the PCIe controller uses an explicit interrupt map and thus doesn't inherit the SoC global interrupt parent.

2015-08-06ARM: ux500: add an SMP enablement type and move cpu nodesLinus Walleij1-26/+27
The "cpus" node cannot be inside the "soc" node, while this works for the CoreSight blocks, the early boot code will look for "cpus" directly under the root node, so this is a hard convention. So move the CPU nodes. Augment the "reg" property to match what is actually in the hardware: 0x300 and 0x301 respectively. Then add an SMP enablement type to be used by the SMP init code, "ste,dbx500-smp". Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Olof Johansson <olof@lixom.net>

All of the keystone devices have a separate register to hold post divider value for main pll clock. Currently the fixed-postdiv value used for k2hk/l/e SoCs works by sheer luck as u-boot happens to use a value of 2 for this. Now that we have fixed this in the pll clock driver change the dt bindings for the same.

The first, for DRA7xx platforms, corrects some incorrect GPMC hardware description data. The second one will ensure that the hwmod code will wait for any module with CPU-accessible registers to become ready before attempting to access it.

2015-07-23ARM: OMAP2+: hwmod: Fix _wait_target_ready() for hwmods without syscRoger Quadros1-8/+16
For hwmods without sysc, _init_mpu_rt_base(oh) won't be called and so _find_mpu_rt_port(oh) will return NULL thus preventing ready state check on those modules after the module is enabled. This can potentially cause a bus access error if the module is accessed before the module is ready. Fix this by unconditionally calling _init_mpu_rt_base() during hwmod _init(). Do ioremap only if we need SYSC access. Eventhough _wait_target_ready() check doesn't really need MPU RT port but just the PRCM registers, we still mandate that the hwmod must have an MPU RT port if ready state check needs to be done. Else it would mean that the module is not accessible by MPU so there is no point in waiting for target to be ready. e.g. this fixes the below DCAN bus access error on AM437x-gp-evm.

2015-07-16ARM: keystone: dts: fix dt bindings for PCIeMurali Karicheri2-0/+2
Currently PCIe DT bindings are broken. PCIe driver can't function without having a SerDes driver that provide the phy configuration. On K2E EVM, this causes problem since the EVM has Marvell SATA controller present and with default values in the SerDes register, it seems to pass the PCIe link check, but causes issues since the configuration is not correct. The manifestation is that when EVM is booted with NFS rootfs, the boot hangs. We shouldn't enable PCIe on this EVM since to work, SerDes driver has to be present as well. So by default, the PCIe DT binding should be disabled in SoC specific DTS. It can be enabled in the board specific DTS when the SerDes device driver is also present. So fix the status of PCIe DT bindings in the SoC specific DTS to "disabled". To enable PCIe, the status should be set to "ok" in the EVM DTS file when SerDes driver support becomes available in the upstream tree.

Since dm9000 driver added support for a vcc regulator, platform data based platforms have their ethernet broken, as the regulator claiming returns -EPROBE_DEFER and prevents dm9000 loading.

2015-07-14ARM: ux500: fix MMC/SD card regressionLinus Walleij4-5/+45
Ux500 is regressing due to commit a21763a0b1e5a5ab8310f581886d04beadc16616 "pinctrl: nomadik: activate strict mux mode" which disallows Nomadik GPIO 5 to be muxed in as a level shifter voltage select pin, as it is currently described as being used for RX on UART1. The behaviour is correct, instead the hardware config has been incorrecly specified: UART1 is indeed unused on HREFv60plus and Snowball and that is why HREFv60plus can use the pins it would normally occupy as the voltage select line for the MMC/SD levelshifter (Snowball uses it for I2C4). The reason UART1 was anyway enabled on these platforms was probably to secure the port enumeration to userspace. This can be solved by using aliases (done in a separate patch) so we can now deactivate UART1 and let MMC/SD use it properly on HREFv60plus. We explicitly activate it only for the older HREFprev60 board. To complete, we set up the pin configuration for these pins properly in the sdi0 node.

Yet these nodes had to set stricter enforcement on them through 'regulator-boot-on' and 'regulator-always-on' to function correctly. The consumers of the regulators this commit affect are the followings: DCDC1: vdd_1v8 system supply, USB-PHY, and ADC DCDC2: Core domain DCDC3: MPU core domain LDO1: RTC LDO2: 3v3 IO domain LDO3: USB-PHY; not a boot-time requirement LDO4: LCD [16:23] All but LDO3 need to be always-on for the system to be functional.

2015-07-08ARM: imx6: gpc: always enable PU domain if CONFIG_PM is not setLucas Stach1-21/+6
If CONFIG_PM is not set the PU power domain needs to be enabled always, otherwise there are two failure scenarios which will hang the system if one of the devices in the PU domain is accessed. 1. New DTs (4.1+) drop the "always-on" property from the PU regulator, so if it isn't properly enabled by the GPC code it will be disabled at the end of boot. 2. If the bootloader already disabled the PU domain the GPC explicitly needs to enable it again, even if the kernel doesn't do any power management. This is a bit hypothetical, as it requires to boot a mainline kernel on a downstream bootloader, as no mainline bootloader disables the PM domains.
