When trying to read any MC13892 ADC channel on a imx51-babbage board: The MC13892 PMIC shutdowns completely. After debugging this issue and comparing the MC13892 and MC13783 initializations done in the vendor kernel, it was noticed that the CHRGRAWDIV bit of the ADC0 register was not being set. This bit is set by default after power on, but the driver was clearing it. After setting this bit it is possible to read the ADC values correctly.

2018-10-23mfd: sec-core: Allow building as moduleKrzysztof Kozlowski
The main MFD driver for Samsung PMICs (S2MPSXX, S5M876X) used with Exynos SoCs can be compiled and used as a module. The dependent clock, regulator and RTC drivers already can be built as a module. Building entire set of drivers as modules might require using initial ramdisk and can make booting process longer (due to probe deferrals). However adding such option is useful for testing and for multi-platform configurations. This also add required module authors to sec-irq.c file based on recent main contributors.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.20 series: Core changes: - A patch series from Hans Verkuil to make it possible to enable/disable IRQs on a GPIO line at runtime and drive GPIO lines as output without having to put/get them from scratch. The irqchip callbacks have been improved so that they can use only the fastpatch callbacks to enable/disable irqs like any normal irqchip, especially the gpiod_lock_as_irq() has been improved to be callable in fastpath context. A bunch of rework had to be done to achieve this but it is a big win since I never liked to restrict this to slowpath. The only call requireing slowpath was try_module_get() and this is kept at the .request_resources() slowpath callback. In the GPIO CEC driver this is a big win sine a single line is used for both outgoing and incoming traffic, and this needs to use IRQs for incoming traffic while actively driving the line for outgoing traffic. - Janusz Krzysztofik improved the GPIO array API to pass a "cookie" (struct gpio_array) and a bitmap for setting or getting multiple GPIO lines at once. This improvement orginated in a specific need to speed up an OMAP1 driver and has led to a much better API and real performance gains when the state of the array can be used to bypass a lot of checks and code when we want things to go really fast. The previous code would minimize the number of calls down to the driver callbacks assuming the CPU speed was orders of magnitude faster than the I/O latency, but this assumption was wrong on several platforms: what we needed to do was to profile and improve the speed on the hot path of the array functions and this change is now completed. - Clean out the painful and hard to grasp BNF experiments from the device tree bindings. Future approaches are looking into using JSON schema for this purpose. (Rob Herring is floating a patch series.) New drivers: - The RCAR driver now supports r8a774a1 (RZ/G2M). - Synopsys GPIO via CREGs driver.

HW supports upto 32 different flowkey algorithms which SW can define, this patch defines 9. NPC RX ACTION has to point to one of these flowkey indices for RSS to work. The configuration is dependent on NPC parse result's layer info.

2018-10-22octeontx2-af: NPC MCAM and LDATA extract minimal configurationSunil Goutham
This patch adds some minimal configuration for NPC MCAM and LDATA extraction which is sufficient enough to install ucast/bcast/promiscuous forwarding rules. Below is the config done - LDATA extraction config to extract DMAC from pkt to offset 64bit in MCAM search key. - Set MCAM lookup keysize to 224bits - Set MCAM TX miss action to UCAST_DEFAULT - Set MCAM RX miss action to DROP Also inorder to have guaranteed space in MCAM to install ucast forwarding rule for each of RVU PF/VF, reserved one MCAM entry for each of NIXLF for ucast rule. And two entries for each of RVU PF. One for bcast pkt replication and other for promiscuous mode which allows all pkts received on a HW CGX/LBK channel.

2018-10-22octeontx2-af: Enable packet length and csum validationSunil Goutham
Config NPC layer info from KPU profile into protocol checker to identify outer L2/IPv4/TCP/UDP headers in a packet. And enable IPv4 checksum validation. L3/L4 and L4 CSUM validation will be enabled by PF/VF drivers by configuring NIX_AF_LF(0..127)_RX_CFG via mbox i.e 'nix_lf_alloc_req->rx_cfg' Also enable setting of NPC_RESULT_S[L2B] when an outer L2 broadcast address is detected. This will help in installing NPC MCAM rules for broadcast packets. Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Allocate memory for mcast/bcast/mirror replication entry contexts, replication buffers (used by HW) and config HW with corresponding memory bases. Added support for installing MCEs via NIX AQ mbox. For now support is restricted to broadcast pkt replication, hence MCE table size and number of replication buffers allocated are less.

Each KPU engine has a 128 entry CAM, only CAM entries which are listed in the profile are enabled and rest are left disabled.

2018-10-22octeontx2-af: Add NPC KPU profileHao Zheng
NPC block is responsible for parsing and forwarding packets to different NIXLFs. NPC has 16 KPU engines (Kangaroo parse engine) and one iKPU which represents pkinds. Each physical port either CGX/LBK is assigned a pkind and upon receiving a packet HW takes that port's pkind and starts parsing as per the KPU engines config. This patch adds header files which contain configuration profile/array for each of the iKPU and 16 KPU engines.

2018-10-22octeontx2-af: NIX Tx scheduler queue config supportSunil Goutham
This patch adds support for a PF/VF driver to configure NIX transmit scheduler queues via mbox. Since PF/VF doesn't know the absolute HW index of the NIXLF attached to it, AF traps the register config and overwrites with the correct NIXLF index. HW supports shaping, colouring and policing of packets with these multilevel traffic scheduler queues. Instead of introducing different mbox message formats for different configurations and making both AF & PF/VF driver implementation cumbersome, access to the scheduler queue's CSRs is provided via mbox. AF checks whether the sender PF/VF has the corresponding queue allocated or not and dumps the config to HW. With a single mbox msg 20 registers can be configured.

2018-10-22octeontx2-af: NIX Tx scheduler queues alloc/freeSunil Goutham
Added support for a PF/VF to allocate or free NIX transmit scheduler queues via mbox. For setting up pkt transmission priorities between queues, the scheduler queues have to be contiguous w.r.t their HW indices. So both contiguous and non-contiguous allocations are supported. Upon receiving NIX_TXSCH_FREE mbox msg all scheduler queues allocated to sending PFFUNC (PF/VF) will be freed. Selective free is not supported.
