2022-06-12riscv: dts: microchip: re-add pdma to mpfs device treeConor Dooley
PolarFire SoC /does/ have a SiFive pdma, despite what I suggested as a conflict resolution to Zong. Somehow the entry fell through the cracks between versions of my dt patches, so re-add it with Zong's updated compatible & dma-channels property.

2022-06-01riscv: dts: microchip: make the fabric dtsi board specificConor Dooley
Currently mpfs-fabric.dtsi is included by mpfs.dtsi - which is fine currently since there is only one board with this SoC upstream. However if another board was added, it would include the fabric contents of the Icicle Kit's reference design. To avoid this, rename mpfs-fabric.dtsi to mpfs-icicle-kit-fabric.dtsi & include it in the dts rather than mpfs.dtsi. mpfs-icicle-kit-fabric.dtsi specifically matches the 22.03 reference design for the icicle kit's FPGA fabric & an older version of the design may not have the i2c or pwm devices - so add the compatible string to document this.

The 600M clock in the fabric is not the real reference, replace it with a 125M clock which is the correct value for the icicle kit. Rename the msspllclk node to mssrefclk since this is now the input to, not the output of, the msspll clock. Control of the msspll clock has been moved into the clock configurator, so add the register range for it to the clk configurator. Finally, add a new output of the clock config block which will provide the 1M reference clock for the MTIMER and the rtc.

2022-04-22riscv: dts: microchip: fix usage of fic clocks on mpfsConor Dooley
The fic clocks passed to the pcie controller and other peripherals in the device tree are not the clocks they actually run on. The fics are actually clock domain crossers & the clock config blocks output is the mss/cpu side input to the interconnect. The peripherals are actually clocked by fixed frequency clocks embedded in the fpga fabric. Fix the device tree so that these peripherals use the correct clocks. The fabric side FIC0 & FIC1 inputs both use the same 125 MHz, so only one clock is created for them.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "There's one large change in the core clk framework here. We change how clk_set_rate_range() works so that the frequency is re-evaulated each time the rate is changed. Previously we wouldn't let clk providers see a rate that was different if it was still within the range, which could be bad for power if the clk could run slower when a range expands. Now the clk provider can decide to do something differently when the constraints change. This broke Nvidia's clk driver so we had to wait for the fix for that to bake a little more in -next. The rate range patch series also introduced a kunit suite for the clk framework that we're going to extend in the next release. It already made it easy to find corner cases in the rate range patches so I'm excited to see it cover more clk code and increase our confidence in core framework patches in the future. I also added a kunit test for the basic clk gate code and that work will continue to cover more basic clk types: muxes, dividers, etc. Beyond the core code we have the usual set of clk driver updates and additions. Qualcomm again dominates the diffstat here with lots more SoCs being supported and i.MX follows afer that with a similar number of SoCs gaining clk drivers. Beyond those large additions there's drivers being modernized to use clk_parent_data so we can move away from global string names for all the clks in an SoC. Finally there's lots of little fixes all over the clk drivers for typos, warnings, and missing clks that aren't critical and get batched up waiting for the next merge window to open. Nothing super big stands out in the driver pile. Full details are below.

2022-03-03riscv: dts: k210: fix broken IRQs on hart1Niklas Cassel
Commit 67d96729a9e7 ("riscv: Update Canaan Kendryte K210 device tree") incorrectly removed two entries from the PLIC interrupt-controller node's interrupts-extended property. The PLIC driver cannot know the mapping between hart contexts and hart ids, so this information has to be provided by device tree, as specified by the PLIC device tree binding. The PLIC driver uses the interrupts-extended property, and initializes the hart context registers in the exact same order as provided by the interrupts-extended property. In other words, if we don't specify the S-mode interrupts, the PLIC driver will simply initialize the hart0 S-mode hart context with the hart1 M-mode configuration. It is therefore essential to specify the S-mode IRQs even though the system itself will only ever be running in M-mode. Re-add the S-mode interrupts, so that we get working IRQs on hart1 again.

2022-01-08kbuild: do not quote string values in include/config/auto.confMasahiro Yamada
The previous commit fixed up all shell scripts to not include include/config/auto.conf. Now that include/config/auto.conf is only included by Makefiles, we can change it into a more Make-friendly form. Previously, Kconfig output string values enclosed with double-quotes (both in the .config and include/config/auto.conf): CONFIG_X="foo bar" Unlike shell, Make handles double-quotes (and single-quotes as well) verbatim. We must rip them off when used. There are some patterns: [1] $(patsubst "%",%,$(CONFIG_X)) [2] $(CONFIG_X:"%"=%) [3] $(subst ",,$(CONFIG_X)) [4] $(shell echo $(CONFIG_X)) These are not only ugly, but also fragile. [1] and [2] do not work if the value contains spaces, like CONFIG_X=" foo bar " [3] does not work correctly if the value contains double-quotes like CONFIG_X="foo\"bar" [4] seems to work better, but has a cost of forking a process. Anyway, quoted strings were always PITA for our Makefiles. This commit changes Kconfig to stop quoting in include/config/auto.conf. These are the string type symbols referenced in Makefiles or scripts: ACPI_CUSTOM_DSDT_FILE ARC_BUILTIN_DTB_NAME ARC_TUNE_MCPU BUILTIN_DTB_SOURCE CC_IMPLICIT_FALLTHROUGH CC_VERSION_TEXT CFG80211_EXTRA_REGDB_KEYDIR EXTRA_FIRMWARE EXTRA_FIRMWARE_DIR EXTRA_TARGETS H8300_BUILTIN_DTB INITRAMFS_SOURCE LOCALVERSION MODULE_SIG_HASH MODULE_SIG_KEY NDS32_BUILTIN_DTB NIOS2_DTB_SOURCE OPENRISC_BUILTIN_DTB SOC_CANAAN_K210_DTB_SOURCE SYSTEM_BLACKLIST_HASH_LIST SYSTEM_REVOCATION_KEYS SYSTEM_TRUSTED_KEYS TARGET_CPU UNUSED_KSYMS_WHITELIST XILINX_MICROBLAZE0_FAMILY XILINX_MICROBLAZE0_HW_VER XTENSA_VARIANT_NAME I checked them one by one, and fixed up the code where necessary.
