Fixes for omaps for v4.7-rc cycle: - Fix dra7 for hardware issues limiting L4Per and L3init power domains to on state. Without this the devices may not work correctly after some time of use because of asymmetric aging. And related to this, let's also remove the unusable states. - Always select omap interconnect for am43x as otherwise the am43x only configurations will not boot properly. This can happen easily for any product kernels that leave out other SoCs to save memory. - Fix DSS PLL2 addresses that have gone unused for now - Select erratum 430973 for omap3, this is now safe to do and can save quite a bit of debugging time for people who may have left it out. * tag 'omap-for-v4.7/fixes-powedomain' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP: DRA7: powerdomain data: Remove unused pwrsts_mem_ret ARM: OMAP: DRA7: powerdomain data: Remove unused pwrsts_logic_ret ARM: OMAP: DRA7: powerdomain data: Set L3init and L4per to ON ARM: OMAP2+: Select OMAP_INTERCONNECT for SOC_AM43XX ARM: dts: DRA74x: fix DSS PLL2 addresses ARM: OMAP2: Enable Errata 430973 for OMAP3 + Linux 4.7-rc2 Signed-off-by: Olof Johansson

ARM: dts: STi: stih407-family: Disable reserved-memory co-processor nodes

2016-06-19T05:21:02+00:00

This patch fixes a non-booting issue in Mainline. When booting with a compressed kernel, we need to be careful how we populate memory close to DDR start. AUTO_ZRELADDR is enabled by default in multi-arch enabled configurations, which place some restrictions on where the kernel is placed and where it will be uncompressed to on boot. AUTO_ZRELADDR takes the decompressor code's start address and masks out the bottom 28 bits to obtain an address to uncompress the kernel to (thus a load address of 0x42000000 means that the kernel will be uncompressed to 0x40000000 i.e. DDR START on this platform). Even changing the load address to after the co-processor's shared memory won't render a booting platform, since the AUTO_ZRELADDR algorithm still ensures the kernel is uncompressed into memory shared with the first co-processor (0x40000000). Another option would be to move loading to 0x4A000000, since this will mean the decompressor will decompress the kernel to 0x48000000. However, this would mean a large chunk (0x44000000 => 0x48000000 (64MB)) of memory would essentially be wasted for no good reason. Until we can work with ST to find a suitable memory location to relocate co-processor shared memory, let's disable the shared memory nodes. This will ensure a working platform in the mean time. NB: The more observant of you will notice that we're leaving the DMU shared memory node enabled; this is because a) it is the only one in active use at the time of this writing and b) it is not affected by the current default behaviour which is causing issues.

ARM: dts: am437x-sk-evm: Reduce i2c0 bus speed for tps65218

2016-06-17T09:59:04+00:00

Based on the latest timing specifications for the TPS65218 from the data sheet, http://www.ti.com/lit/ds/symlink/tps65218.pdf, document SLDS206 from November 2014, we must change the i2c bus speed to better fit within the minimum high SCL time required for proper i2c transfer. When running at 400khz, measurements show that SCL spends 0.8125 uS/1.666 uS high/low which violates the requirement for minimum high period of SCL provided in datasheet Table 7.6 which is 1 uS. Switching to 100khz gives us 5 uS/5 uS high/low which both fall above the minimum given values for 100 khz, 4.0 uS/4.7 uS high/low. Without this patch occasionally a voltage set operation from the kernel will appear to have worked but the actual voltage reflected on the PMIC will not have updated, causing problems especially with cpufreq that may update to a higher OPP without actually raising the voltage on DCDC2, leading to a hang.

ARM: dts: armada-38x: fix MBUS_ID for crypto SRAM on Armada 385 Linksys

2016-06-16T15:01:28+00:00

When the support for the Marvell crypto engine was added in the Device Tree of the various Armada 385 Device Tree files in commit d716f2e837ac6 ("ARM: mvebu: define crypto SRAM ranges for all armada-38x boards"), a typo was made in the MBus window attributes for the Armada 385 Linksys board: 0x09/0x05 are used instead of 0x19/0x15. This commit fixes this typo, which makes the CESA engines operational on Armada 385 Linksys boards.
