ARM: dts: dra7-evm: Make VDDA_1V8_PHY supply always on

2014-08-07T23:53:53+00:00

commit e120fb459693bbc1ac3eabdd65c3659d7cfbfd2a upstream. After clarification from the hardware team it was found that this 1.8V PHY supply can't be switched OFF when SoC is Active. Since the PHY IPs don't contain isolation logic built in the design to allow the power rail to be switched off, there is a very high risk of IP reliability and additional leakage paths which can result in additional power consumption. The only scenario where this rail can be switched off is part of Power on reset sequencing, but it needs to be kept always-on during operation. This patch is required for proper functionality of USB, SATA and PCIe on DRA7-evm.

ARM: mvebu: Fix the improper use of the compatible string armada38x using a wildcard

2014-07-09T18:21:29+00:00

commit 8dbdb8e704db34085f5978c335c10256b0fb9629 upstream. Wildcards in compatible strings should be avoid. "marvell,armada38x" was recently introduced but was not yet used. The armada 385 SoC is a superset of the armada 380 SoC (with more CPUs and more PCIe slots). So this patch replaces the use of "marvell,armada38x" by the "marvell,armada380" string.

ARM: mvebu: DT: fix OpenBlocks AX3-4 RAM size

2014-07-01T03:14:01+00:00

commit e47043aea3853a74a9aa5726a1faa916d7462ab7 upstream. The OpenBlocks AX3-4 has a non-DT bootloader. It also comes with 1GB of soldered on RAM, and a DIMM slot for expansion. Unfortunately, atags_to_fdt() doesn't work in big-endian mode, so we see the following failure when attempting to boot a big-endian kernel: 686 slab pages 17 pages shared 0 pages swap cached [ pid ] uid tgid total_vm rss nr_ptes swapents oom_score_adj name Kernel panic - not syncing: Out of memory and no killable processes...

ARM: mvebu: fix definitions of PCIe interfaces on Armada 38x

2014-05-22T14:12:54+00:00

Due a copy/paste error, the 'reg' values for the third PCIe interface on Armada 380, and the third and fourth PCIe interfaces on Armada 385 are wrong: they are equal to the one of the second PCIe interface. This patch fixes this by using the appropriate 'reg' values for those PCIe interfaces. Without this fix, the third and fourth PCIe interfaces are unusable on those platforms.

Samsung fixes for 3.15 from Kukjin Kim: - Remove g2d_pd and mau_pd nodes on exynos5420. Since the power domains are linked to the CMU blocks, kernel panic happens during access clocks when the power domains are disabled. Now this is a best solution. - Enable HS-I2C on exynos5 by default MMC partition cannot be mounted for RFS without the enabling HS-I2C because regulators for MMC power are connected to HS-I2C bus. - Disable MDMA1 node on exynos5420 When MDMA1 runs in secure mode it makes kernel fault, so need to disalbe it on exynos5420 by default instead of each board. - Fix the secondary CPU boot for exynos4212 * tag 'samsung-fixes' of http://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung: ARM: dts: Remove g2d_pd node for exynos5420 ARM: dts: Remove mau_pd node for exynos5420 ARM: exynos_defconfig: enable HS-I2C to fix for mmc partition mount ARM: dts: disable MDMA1 node for exynos5420 ARM: EXYNOS: fix the secondary CPU boot of exynos4212 Signed-off-by: Olof Johansson
