Hi Sylwester,

I've queued this patch for 3.20. Would be nice to have a Reviewed-by tag from
someone else who has access to the SoC documentation though.
Pankaj Dubey has reviewed this patch [1].
He has pointed out that there is
Hi,
3.19-rc1 still misses these two patches:
156823e arm: dts: Exynos5: Use pmu_system_controller phandle for dp phy
03c16e7 ARM: exynos_defconfig: Enable options for display panel support156823e
and without them, the display doesn't turn on on my peachpi: can we have them
queued for rc2?

Exynos4 SoCs equipped with an L2C-310 cache controller and running under
secure firmware require certain registers of aforementioned IP to be
accessed only from secure mode. This means that SMC calls are required
for certain register writes. To handle this, an

On Exynos SoCs it is necessary to resume operation of L2C early in

[rewrote the code
This is an updated patchset, which intends to add support for L2 cache
on Exynos4 SoCs on boards running under secure firmware, which requires
certain initialization steps to be done with help of firmware, as
selected registers are writable only from secure mode.

Because certain secure hypervisor do not allow writes to individual L2C

This patch implements generic DT L2C initialisation (the one from
