2020-05-29power: supply: sbs-battery: add ability to disable charger broadcastsJean-Francois Dagenais1-0/+2
In certain designs, it is possible to add a battery on a populated i2c bus without an sbs compliant charger. In that case, the battery will unnecessarily and sometimes undesirably master the bus trying to write info in the charger. It is observed in many occasion that these battery "broadcasts" are even corrupting other ongoing master to slave communication. I.e. the multi-master support in the battery is inadequate. Thankfully, the CHARGER_MODE bit allows designers to disable that SBS battery behaviour. This needs to be done once when the battery is first seen on the bus.

2020-05-28Merge branch 'baikal/drivers' into arm/driversArnd Bergmann2-0/+197
[arnd: This is a patch series from Serge Semin to add a few drivers that don't have any other subsystem maintainer tree to go through, so I'm picking them up through the soc tree, full series description from the mailing list below] Baikal-T1 SoC CPU is based on two MIPS Warrior P5600 cores. Their main memory Non-Coherent IO interface is connected to the OCP2AXI bridge, which in turn is then connected to the DW AMBA 3 AXI Interconnect (so called Main Interconnect) with nine masters and four slaves ports. Main Interconnect is responsible for the AXI-bus traffic arbitration (QoS) and its routing from one component to another. In addition there is a Errors Handler Block (EHB) accesible by means of the Baikal-T1 SoC System Controller responsible to detect AXI protocol errors and device not responding situations built on top the interconnect. Baikal-T1 AXI-bus driver included in this patchset will be responsible for working with that functionality, though currently it doesn't support QoS tuning. Instead it's capable of detecting the error events, reporting an info about them to the system log, injecting artificial errors to test the driver functionality. Since AXI Interconnect doesn't provide a way to find out which devices are connected to it, so its DT node is supposed to be compatible with "simple-bus" driver, while sub-nodes shall represent the masters attached to the bus. One of the AXI Interconnect slaves is an AXI-APB bridge used to access the Baikal-T1 SoC subsystems CSRs. MMIO request from CPU and DMAC masters are routed there if they are detected to be within [0x08000000 0x1FFFFFFF] range of the physical memory. In case if an attempted APB transaction stays with no response for a pre-defined time it will be detected by the APB-bus Errors Handler Block (EHB), which will raise an interrupt, then the bus gets freed for a next operation. The APB-bus driver provides the interrupt handler to detect the erroneous address, update an errors counter and prints an error message about the faulty address. The counter and the APB-bus operations timeout can be accessed via corresponding sysfs nodes. A dedicated sysfs-node can be also used to artificially cause the bus errors described above. Since APB-bus is a platform bus, it doesn't provide a way to detect slave devices connected to it, so similarly to the AXI-bus it's also supposed to be compatible with "simple-bus" driver. Aside from PCIe/SATA/DDR/I2C/EHB/CPU/reboot specific settings the Baikal-T1 System Controller provides a MIPS P5600 CM2 L2-cache tuning block. It is responsible for the setting up the Tag/Data/WS L2-to-RAM latencies. The last small patch in this patchset provides a driver and DT-schema-based binding for the described device. So that the latencies can be tuned up by means of dedicated DT properties and sysfs nodes. This patchset is rebased and tested on the mainline Linux kernel 5.7-rc4. Changelog v2 (AXI/APB bus): - Assign dual GPL/BSD licenses to the bindings. - Use single lined copyright headers in the bindings. - Replace "additionalProperties: false" property with "unevaluatedProperties: false" in the bindings. - Don't use a multi-arg clock phandle reference in DT binding examples. Thus remove includes from there. - Fix some commit message and Kconfig help text spelling. - Move drivers from soc to the bus subsystem. - Convert a simple EHB drivers to the Baikal-T1 AXI and APB bus ones. - Convert APB bus driver to using regmap MMIO API. - Use syscon regmap to access the AXI-bus erroneous address. - Add reset line support. - Add Main Interconnect clock support to the AXI-bus driver. - Remove probe-status info string printout. - Discard of_match_ptr() macro utilization. - Don't print error-message if no platform IRQ found. Just return an error. - Use generic FIELD_{GET,PREP} macros instead of handwritten ones in the AXI-bus driver. Changelog v2 (l2 driver): - Fix some commit message and Kconfig help text spelling. - Move the driver to the memory subsystem. - Assign dual GPL/BSD license to the DT binding. - Use single lined copyright header in the binding. - Discard reg property and syscon compatible string. - Move "allOf" restrictions to the root level of the properties. - The DT node is supposed to be a child of the Baikal-T1 system controller node. So regmap will be fetched from there. - Use generic FIELD_{GET,PREP} macro. - Remove probe-status info string printout. - Since the driver depends on the OF config we can remove of_match_ptr() macro utilization. Changelog v3: - Combine l2 and AXI/APB bus patches in a single patchset. - Retrieve AXI-bus QoS registers by resource name "qos". - Discard CONFIG_OF dependency since there is none at compile-time. - Add syscon EHB registers range to the AXI-bus reg property as optional entry. - Fix invalid of_property_read_u32() return value test in the l2-ctl driver. - Get the reg property back into the l2-ctl DT bindings even though the driver is using the parental syscon regmap. - The l2-ctl DT schema will live separately from the system controller, but the corresponding sub-node of the later DT schema will $ref this one. - Set non-default latencies in the l2-ctl DT example. * baikal/drivers: memory: Add Baikal-T1 L2-cache Control Block driver bus: Add Baikal-T1 APB-bus driver bus: Add Baikal-T1 AXI-bus driver dt-bindings: bus: Add Baikal-T1 APB-bus binding dt-bindings: bus: Add Baikal-T1 AXI-bus binding Link: https://lore.kernel.org/lkml/20200526130841.ap6qlxv7hqmabnh5@mobilestation/ Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2020-05-28dt-bindings: mmc: Document the Amlogic Meson SDHC MMC host controllerMartin Blumenstingl1-0/+68
This documents the devicetree bindings for the SDHC MMC host controller found in Meson6, Meson8, Meson8b and Meson8m2 SoCs. It can use a bus-width of 1/4/8-bit and it supports eMMC spec 4.4x/4.5x including HS200 mode (up to 100MHz clock). It embeds an internal clock controller which outputs four clocks (mod_clk, sd_clk, tx_clk and rx_clk) and is fed by four external input clocks (clkin[0-3]). "pclk" is the module register clock, it has to be enabled to access the registers.
