2022-03-30riscv: dts: canaan: Fix SPI3 bus widthNiklas Cassel4-0/+8
According to the K210 Standalone SDK Programming guide: https://canaan-creative.com/wp-content/uploads/2020/03/kendryte_standalone_programming_guide_20190311144158_en.pdf Section 15.4.3.3: SPI0 and SPI1 supports: standard, dual, quad and octal transfers. SPI3 supports: standard, dual and quad transfers (octal is not supported). In order to support quad transfers (Quad SPI), SPI3 must have four IO wires connected to the SPI flash. Update the device tree to specify the correct bus width. Tested on maix bit, maix dock and maixduino, which all have the same SPI flash (gd25lq128d) connected to SPI3. maix go is untested, but it would not make sense for this k210 board to be designed differently.

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. Core: - Make clk_set_rate_range() re-evaluate the limits each time - Introduce various clk_set_rate_range() tests - Add clk_drop_range() to drop a previously set range New Drivers: - i.MXRT1050 clock driver and bindings - i.MX8DXL clock driver and bindings - i.MX93 clock driver and bindings - NCO blocks on Apple SoCs - Audio clks on StarFive JH7100 RISC-V SoC - Add support for the new Renesas RZ/V2L SoC - Qualcomm SDX65 A7 PLL - Qualcomm SM6350 GPU clks - Qualcomm SM6125, SM6350, QCS2290 display clks - Qualcomm MSM8226 multimedia clks Updates: - Kunit tests for clk-gate implementation - Terminate arrays with sentinels and make that clearer - Cleanup SPDX tags - Fix typos in comments - Mark mux table as const in clk-mux - Make the all_lists array const - Convert Cirrus Logic CS2000P driver to regmap, yamlify DT binding and add support for dynamic mode - Clock configuration on Microchip PolarFire SoCs - Free allocations on probe error in Mediatek clk driver - Modernize Mediatek clk driver by consolidating code - Add watchdog (WDT), I2C, and pin function controller (PFC) clocks on Renesas R-Car S4-8 - Improve the clocks for the Rockchip rk3568 display outputs (parenting, pll-rates) - Use of_device_get_match_data() instead of open-coding on Rockchip rk3568 - Reintroduce the expected fractional-divider behaviour that disappeared with the addition of CLK_FRAC_DIVIDER_POWER_OF_TWO_PS - Remove SYS PLL 1/2 clock gates for i.MX8M* - Remove AUDIO MCLK ROOT from i.MX7D - Add fracn gppll clock type used by i.MX93 - Add new composite clock for i.MX93 - Add missing media mipi phy ref clock for i.MX8MP - Fix off by one in imx_lpcg_parse_clks_from_dt() - Rework for the imx pll14xx - sama7g5: One low priority fix for GCLK of PDMC - Add DMA engine (SYS-DMAC) clocks on Renesas R-Car S4-8 - Add MOST (MediaLB I/F) clocks on Renesas R-Car E3 and D3 - Add CAN-FD clocks on Renesas R-Car V3U - Qualcomm SC8280XP RPMCC - Add some missing clks on Qualcomm MSM8992/MSM8994/MSM8998 SoCs - Rework Qualcomm GCC bindings and convert SDM845 camera bindig to YAML - Convert various Qualcomm drivers to use clk_parent_data - Remove test clocks from various Qualcomm drivers - Crypto engine clks on Qualcomm IPQ806x + more freqs for SDCC/NSS - Qualcomm SM8150 EMAC, PCIe, UFS GDSCs - Better pixel clk frequency support on Qualcomm RCG2 clks" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (227 commits) clk: zynq: Update the parameters to zynq_clk_register_periph_clk clk: zynq: trivial warning fix clk: Drop the rate range on clk_put() clk: test: Test clk_set_rate_range on orphan mux clk: Initialize orphan req_rate dt-bindings: clock: drop useless consumer example dt-bindings: clock: renesas: Make example 'clocks' parsable clk: qcom: gcc-msm8994: Fix gpll4 width dt-bindings: clock: fix dt_binding_check error for qcom,gcc-other.yaml clk: rs9: Add Renesas 9-series PCIe clock generator driver clk: fixed-factor: Introduce devm_clk_hw_register_fixed_factor_index() clk: visconti: prevent array overflow in visconti_clk_register_gates() dt-bindings: clk: rs9: Add Renesas 9-series I2C PCIe clock generator clk: sifive: Move all stuff into SoCs header files from C files clk: sifive: Add SoCs prefix in each SoCs-dependent data riscv: dts: Change the macro name of prci in each device node dt-bindings: change the macro name of prci in header files and example clk: sifive: duplicate the macro definitions for the time being clk: qcom: sm6125-gcc: fix typos in comments clk: ti: clkctrl: fix typos in comments ...

2022-03-03riscv: dts: k210: fix broken IRQs on hart1Niklas Cassel1-1/+2
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 Yamada1-3/+1
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.

The existing values are rejected by the da9063 regulator driver, as they are unachievable with the declared chip setup (non-merged vcore and bmem are unable to provide the declared curent). Fix voltages to match rev3 schematics, which also matches their boot-up configuration within the chip's available precision. Declare bcore1/bcore2 and bmem/bio as merged. Set ldo09 and ldo10 as always-on as their consumers are not declared but exist. Drop ldo current limits as there is no current limit feature for these regulators in the DA9063.
