[PATCH 2/2] drm/exynos: dp: fix wrong return type

This patch fixes wrong return type when dt binding of bridge device failed. If a board has a bridge device then of_graph_get_remote_port_parent function shouldn't be NULL. So this patch will return a proper error type so that the deferred probe isn't triggered. Signed-off-by: Inki Dae

[PATCH 1/2] drm/exynos: dp: add of_graph dt binding support for panel

[PATCH v2 0/4] Exynos4210: fix power domain for MDMA1 device

This patchset fixes mysterious boot hang on Exynos 4210 SoCs, when IOMMU is enabled. There is no direct dependency between IOMMU devices and MDMA1. However enabling IOMMU changes the device probe order, what results in LCD0 power domain being turned off for some time. During that time the

[PATCH v2 2/4] driver core: handle -EPROBE_DEFER from bus_type.match()

From: Tomeu Vizoso Lets implementations of the match() callback in struct bus_type to return errors and if it's -EPROBE_DEFER then queue the device for deferred probing. This is useful to buses such as AMBA in which devices are registered before their matching

[PATCH v2 3/4] ARM: amba: Move reading of periphid to amba_match()

From: Tomeu Vizoso Reading the periphid when the Primecell device is registered means that the apb pclk must be available by then or the device won't be registered at all. By reading the periphid in amba_match() we can return -EPROBE_DEFER if the apb pclk isn't there

[PATCH v2 4/4] ARM: amba: Properly handle devices with power domains

To read pid/cid registers, the probed device need to be properly turned on. When it is inside a power domain, the bus code should ensure that the given power domain is enabled before trying to access device's registers. Signed-off-by: Marek Szyprowski ---

[PATCH v2 1/4] ARM: dts: exynos4210: MDMA1 device belongs to LCD0 power domain

On Exynos 4210 MDMA1 device belongs to LCD0 power domain, so add proper power-domains property. On Exynos 4x12, it belongs to TOP power domain, which is always enabled, thus require no assignment in exynos4x12.dtsi. Signed-off-by: Marek Szyprowski ---
