2019-09-02mfd / platform: cros_ec: Handle chained ECs as platform devicesEnric Balletbo i Serra1-0/+18
An MFD is a device that contains several sub-devices (cells). For instance, the ChromeOS EC fits in this description as usually contains a charger and can have other devices with different functions like a Real-Time Clock, an Audio codec, a Real-Time Clock, ... If you look at the driver, though, we're doing something odd. We have two MFD cros-ec drivers where one of them (cros-ec-core) instantiates another MFD driver as sub-driver (cros-ec-dev), and the latest instantiates the different sub-devices (Real-Time Clock, Audio codec, etc). MFD ------------------------------------------ cros-ec-core |___ mfd-cellA (cros-ec-dev) | |__ mfd-cell0 | |__ mfd-cell1 | |__ ... | |___ mfd-cellB (cros-ec-dev) |__ mfd-cell0 |__ mfd-cell1 |__ ... The problem that was trying to solve is to describe some kind of topology for the case where we have an EC (cros-ec) chained with another EC (cros-pd). Apart from that this extends the bounds of what MFD was designed to do we might be interested on have other kinds of topology that can't be implemented in that way. Let's prepare the code to move the cros-ec-core part from MFD to platform/chrome as this is clearly a platform specific thing non-related to a MFD device. platform/chrome | MFD ------------------------------------------ | cros-ec ________|___ cros-ec-dev | |__ mfd-cell0 | |__ mfd-cell1 | |__ ... | cros-pd ________|___ cros-ec-dev | |__ mfd-cell0 | |__ mfd-cell1 | |__ ...

2019-09-02mfd: Add support for Merrifield Basin Cove PMICAndy Shevchenko1-0/+81
Add an MFD driver for Intel Merrifield Basin Cove PMIC. Firmware on the platforms which are using Basin Cove PMIC is "smarter" than on the rest supported by vanilla kernel. It handles first level of interrupt itself, while others do it on OS level. The driver is done in the same way as the rest of Intel PMIC MFD drivers in the kernel to support the initial design. The design allows to use one driver among few PMICs without knowing implementation details of the each hardware version or generation.

2019-08-30mm: memcontrol: flush percpu slab vmstats on kmem offliningRoman Gushchin1-2/+3
I've noticed that the "slab" value in memory.stat is sometimes 0, even if some children memory cgroups have a non-zero "slab" value. The following investigation showed that this is the result of the kmem_cache reparenting in combination with the per-cpu batching of slab vmstats. At the offlining some vmstat value may leave in the percpu cache, not being propagated upwards by the cgroup hierarchy. It means that stats on ancestor levels are lower than actual. Later when slab pages are released, the precise number of pages is substracted on the parent level, making the value negative. We don't show negative values, 0 is printed instead. To fix this issue, let's flush percpu slab memcg and lruvec stats on memcg offlining. This guarantees that numbers on all ancestor levels are accurate and match the actual number of outstanding slab pages.

2019-08-31xsk: add support to allow unaligned chunk placementKevin Laatz2-4/+80
Currently, addresses are chunk size aligned. This means, we are very restricted in terms of where we can place chunk within the umem. For example, if we have a chunk size of 2k, then our chunks can only be placed at 0,2k,4k,6k,8k... and so on (ie. every 2k starting from 0). This patch introduces the ability to use unaligned chunks. With these changes, we are no longer bound to having to place chunks at a 2k (or whatever your chunk size is) interval. Since we are no longer dealing with aligned chunks, they can now cross page boundaries. Checks for page contiguity have been added in order to keep track of which pages are followed by a physically contiguous page.

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs David Howells says: ==================== rxrpc: Fix use of skb_cow_data() Here's a series of patches that replaces the use of skb_cow_data() in rxrpc with skb_unshare() early on in the input process. The problem that is being seen is that skb_cow_data() indirectly requires that the maximum usage count on an sk_buff be 1, and it may generate an assertion failure in pskb_expand_head() if not. This can occur because rxrpc_input_data() may be still holding a ref when it has just attached the sk_buff to the rx ring and given that attachment its own ref. If recvmsg happens fast enough, skb_cow_data() can see the ref still held by the softirq handler. Further, a packet may contain multiple subpackets, each of which gets its own attachment to the ring and its own ref - also making skb_cow_data() go bang. Fix this by: (1) The DATA packet is currently parsed for subpackets twice by the input routines. Parse it just once instead and make notes in the sk_buff private data. (2) Use the notes from (1) when attaching the packet to the ring multiple times. Once the packet is attached to the ring, recvmsg can see it and start modifying it, so the softirq handler is not permitted to look inside it from that point. (3) Pass the ref from the input code to the ring rather than getting an extra ref. rxrpc_input_data() uses a ref on the second refcount to prevent the packet from evaporating under it. (4) Call skb_unshare() on secured DATA packets in rxrpc_input_packet() before we take call->input_lock. Other sorts of packets don't get modified and so can be left. A trace is emitted if skb_unshare() eats the skb. Note that skb_share() for our accounting in this regard as we can't see the parameters in the packet to log in a trace line if it releases it. (5) Remove the calls to skb_cow_data(). These are then no longer necessary. There are also patches to improve the rxrpc_skb tracepoint to make sure that Tx-derived buffers are identified separately from Rx-derived buffers in the trace. ==================== Signed-off-by: David S.

In previous mt2712/mt8173, MediaTek extend the v7s to support 4GB dram. But in the latest mt8183, We extend it to support the PA up to 34bit. Then the "MTK_4GB" name is not so fit, This patch only change the quirk name to "MTK_EXT".

2019-08-30dt-bindings: mediatek: Add binding for mt8183 IOMMU and SMIYong Wu1-0/+130
This patch adds decriptions for mt8183 IOMMU and SMI. mt8183 has only one M4U like mt8173 and is also MTK IOMMU gen2 which uses ARM Short-Descriptor translation table format. The mt8183 M4U-SMI HW diagram is as below: EMI | M4U | ---------- | | gals0-rx gals1-rx | | | | gals0-tx gals1-tx | | ------------ SMI Common ------------ | +-----+-----+--------+-----+-----+-------+-------+ | | | | | | | | | | gals-rx gals-rx | gals-rx gals-rx gals-rx | | | | | | | | | | | | | | | | | | gals-tx gals-tx | gals-tx gals-tx gals-tx | | | | | | | | larb0 larb1 IPU0 IPU1 larb4 larb5 larb6 CCU disp vdec img cam venc img cam All the connections are HW fixed, SW can NOT adjust it. Compared with mt8173, we add a GALS(Global Async Local Sync) module between SMI-common and M4U, and additional GALS between larb2/3/5/6 and SMI-common. GALS can help synchronize for the modules in different clock frequency, it can be seen as a "asynchronous fifo". GALS can only help transfer the command/data while it doesn't have the configuring register, thus it has the special "smi" clock and it doesn't have the "apb" clock. From the diagram above, we add "gals0" and "gals1" clocks for smi-common and add a "gals" clock for smi-larb. >From the diagram above, IPU0/IPU1(Image Processor Unit) and CCU(Camera Control Unit) is connected with smi-common directly, we can take them as "larb2", "larb3" and "larb7", and their register spaces are different with the normal larb.

2019-08-30writeback: add tracepoints for cgroup foreign writebacksTejun Heo1-0/+123
cgroup foreign inode handling has quite a bit of heuristics and internal states which sometimes makes it difficult to understand what's going on. Add tracepoints to improve visibility. Signed-off-by: Tejun Heo <[email protected]> Signed-off-by: Jens Axboe <[email protected]>

2019-08-30usb: gadget: net2280: Move all "ll" registers in one structureBenjamin Herrenschmidt1-10/+25
The split into multiple structures of the "ll" register bank is impractical. It makes it hard to add ll_lfps_timers_2 which is at offset 0x794, which is outside of the existing "lfps" structure and would require us to add yet another one. Instead, move all the "ll" registers into a single usb338x_ll_regs structure, and add ll_lfps_timers_2 while at it. It will be used in a subsequent patch.
