* ARM: lpc18xx: define low-level debug symbol for LPC18xx/43xxJoachim Eastwood2015-05-201-1/+9

* ARM: lpc18xx: add basic support for NXP LPC18xx/43xx SoCsJoachim Eastwood2015-05-156-1/+49
| | | | | | | | | | | | | | Add support for NXP's LPC18xx (Cortex-M3) and LPC43xx (Cortex-M4) SoCs. These SoCs are NXP's high preformance MCU line and can run at clock speeds up to 180 MHz for LPC18xx and 204 MHz for LPC43xx. LPC43xx is more or less a LPC18xx with a Cortex-M4F core and a few extra peripherals. The LPC43xx series also features one or two Cortex-M0 cores that can be used to offload the main M4 core.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge "pxa changes for v4.2 cycle" from Robert Jarzmik: The main and only feature is the conversion of all pxa variants to clock framework. This encompasses pxa25x, pxa27x and pxa3xx, for all boards. This should be a disruptive cycle in the normally quiet pxa history, as the change can break any platform, and the test were performed on only 4 boards (lubbock, zylonite, mioa701, cm-x300). * tag 'pxa-for-4.2' of https://github.com/rjarzmik/linux: ARM: pxa: Constify irq_domain_ops ARM: pxa: Transition pxa25x, pxa27x, pxa3xx to clk framework ARM: pxa: convert eseries to clock framework ARM: pxa: Transition pxa25x and pxa27x to clk framework ARM: pxa: pxa27x skip default device initialization with DT clk: pxa: add missing pxa27x clocks for Irda and sa1100-rtc ARM: pxa: move gpio11 clock to board files ARM: pxa: change clocks init sequence

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since pxa clocks were ported to the clock framework, an ordering issue appears between clocks and clocksource initialization. As a consequence, the pxa timer clock cannot be acquired in pxa_timer, and is disabled by clock framework because it is "unused". The ordering issue is that in the kernel boot sequence : start_kernel() ... time_init() -> pxa_timer() -> here the clocksource is initialized ... rest_init() kernel_init() initcalls -> here the clocks are initialized In the current sequence, the clocks are initialized way after pxa_timer, which cannot acquire the OSTIMER0 clock. To solve this issue, the clocks initialization is moved to pxa_timer(), so that clocks are initialized before clocksource for non device-tree. For device-tree, the standard arm time_init() will take care of the ordering. Reviewed-by: Michael Turquette <mturquette@linaro.org> Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>

PMC scratch register 41 is used by tegra LP1 resume code for retrieving stored physical memory address of common resume function and in the same time used by tegra20_cpu_shutdown() (shared by Tegra20 cpuidle driver and platform SMP code), which is storing CPU1 "resettable" status.

Since I've missed to send this via arm-soc tree before v4.1-rc3, so I'm sending this to you directly - fix commit ea08de16eb1b ("ARM: dts: Add DISP1 power domain for exynos5420") which causes 'unhandled fault: imprecise external abort' error when PD turned off. ("make DP a consumer of DISP1 power domain") - fix 's3c-rtc' probe failure on Odriod-X2/U2/U3 boards ("add 'rtc_src' clock to rtc node for source clock of rtc") - fix typo for 'cpu-crit-0' trip point on exynos5420/5440 - fix S2R failure on exynos5250-snow due to card power of Marvell WiFi driver (suspend/resume) ("add keep-power-in-susped to WiFi SDIO node")" * tag 'samsung-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung: ARM: dts: Add keep-power-in-suspend to WiFi SDIO node for exynos5250-snow ARM: dts: Fix typo in trip point temperature for exynos5420/5440 ARM: dts: add 'rtc_src' clock to rtc node for exynos4412-odroid boards ARM: dts: Make DP a consumer of DISP1 power domain on Exynos5420

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Marvell mwifiex driver prevents the system to enter into a suspend state if the card power is not preserved during a suspend/resume cycle. So Suspend-to-RAM and Suspend-to-idle are failing on Exynos5250 Snow. Add the keep-power-in-suspend Power Management property to the SDIO/MMC node so the mwifiex suspend handler doesn't fail and the system is able to enter into a suspend state.

This causes an "Unhandled fault: imprecise external abort" error if the exynos-dp driver tries to access the DP controller registers and the PD was turned off. This lead to a kernel panic and a complete system hang. Make the DP controller device node a consumer of the DISP1 power domain to ensure that the PD is turned on when the exynos-dp driver is probed.
