New device specific parameter of rockchip,sfc-no-dma included in documentation. Signed-off-by: Chris Morgan Signed-off-by: Jon Lin --- Changes in v11: None Changes in v10: None Changes in v9: None Changes in v8: - Fix indent 4 to 2 in yaml Changes in v7: - Fix up the sclk_sfc parent error in rk3036 - Unify to "rockchip,sfc" compatible id because all the feature update will have a new IP version, so the driver is used for the SFC IP in all SoCs - Change to use node "sfc" to name the SFC pinctrl group - Add subnode reg property check - Add rockchip_sfc_adjust_op_size to workaround in CMD + DUMMY case - Limit max_iosize to 32KB Changes in v6: - Add support in device trees for rv1126(Declared in series 5 but not submitted) - Change to use "clk_sfc" "hclk_sfc" as clock lable, since it does not affect interpretation and has been widely used - Support sfc tx_dual, tx_quad(Declared in series 5 but not submitted) - Simplify the code, such as remove "rockchip_sfc_register_all"(Declared in series 5 but not submitted) - Support SFC ver4 ver5(Declared in series 5 but not submitted) - Add author Chris Morgan and Jon Lin to spi-rockchip-sfc.c - Change to use devm_spi_alloc_master and spi_unregister_master Changes in v5: - Add support in device trees for rv1126 - Support sfc tx_dual, tx_quad - Simplify the code, such as remove "rockchip_sfc_register_all" - Support SFC ver4 ver5 Changes in v4: - Changing patch back to an "RFC". An engineer from Rockchip reached out to me to let me know they are working on this patch for upstream, I am submitting this v4 for the community to see however I expect Jon Lin (jon.lin@rock-chips.com) will submit new patches soon and these are the ones we should pursue for mainlining. Jon's patch series should include support for more hardware than this series. - Clean up documentation more and ensure it is correct per make dt_binding_check. - Add support in device trees for rk3036, rk3308, and rv1108. - Add ahb clock (hclk_sfc) support for rk3036. - Change rockchip_sfc_wait_fifo_ready() to use a switch statement. - Change IRQ code to only mark IRQ as handled if it handles the specific IRQ (DMA transfer finish) it is supposed to handle. Changes in v3: - Changed the name of the clocks to sfc/ahb (from clk-sfc/clk-hsfc). - Changed the compatible string from rockchip,sfc to rockchip,rk3036-sfc. A quick glance at the datasheets suggests this driver should work for the PX30, RK180x, RK3036, RK312x, RK3308 and RV1108 SoCs, and possibly more. However, I am currently only able to test this on a PX30 (an RK3326). The technical reference manuals appear to list the same registers for each device. - Corrected devicetree documentation for formatting and to note these changes. - Replaced the maintainer with Heiko Stuebner and myself, as we will take ownership of this going forward. - Noted that the device (per the reference manual) supports 4 CS, but I am only able to test a single CS (CS 0). - Reordered patches to comply with upstream rules. Changes in v2: - Reimplemented driver using spi-mem subsystem. - Removed power management code as I couldn't get it working properly. - Added device tree bindings for Odroid Go Advance. Changes in v1: hanges made in this new series versus the v8 of the old series: - Added function to read spi-rx-bus-width from device tree, in the event that the SPI chip supports 4x mode but only has 2 pins wired (such as the Odroid Go Advance). - Changed device tree documentation from txt to yaml format. - Made "reset" message a dev_dbg from a dev_info. - Changed read and write fifo functions to remove redundant checks. - Changed the write and read from relaxed to non-relaxed when starting the DMA transfer or reading the DMA IRQ. - Changed from dma_coerce_mask_and_coherent to just dma_set_mask_and_coherent. - Changed name of get_if_type to rockchip_sfc_get_if_type. .../devicetree/bindings/spi/rockchip-sfc.yaml | 88 +++++++++++++++++++ 1 file changed, 88 insertions(+) create mode 100644 Documentation/devicetree/bindings/spi/rockchip-sfc.yaml diff --git a/Documentation/devicetree/bindings/spi/rockchip-sfc.yaml b/Documentation/devicetree/bindings/spi/rockchip-sfc.yaml new file mode 100644 index 000000000000..162993a97290 --- /dev/null +++ b/Documentation/devicetree/bindings/spi/rockchip-sfc.yaml @@ -0,0 +1,88 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/spi/rockchip-sfc.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Rockchip Serial Flash Controller (SFC) + +maintainers: + - Heiko Stuebner + - Chris Morgan + +allOf: + - $ref: spi-controller.yaml# + +properties: + compatible: + oneOf: + - const: rockchip,sfc + + reg: + maxItems: 1 + + interrupts: + maxItems: 1 + + clocks: + items: + - description: Bus Clock + - description: Module Clock + + clock-names: + items: + - const: clk_sfc + - const: hclk_sfc + + power-domains: + maxItems: 1 + + rockchip,sfc-no-dma: + description: Disable DMA and utilize FIFO mode only + type: boolean + +patternProperties: + "^flash@[0-3]$": + type: object + properties: + reg: + minimum: 0 + maximum: 3 + +required: + - compatible + - reg + - interrupts + - clocks + - clock-names + +unevaluatedProperties: false + +examples: + - | + #include + #include + #include + + sfc: spi@ff3a0000 { + compatible = "rockchip,sfc"; + reg = <0xff3a0000 0x4000>; + interrupts = ; + clocks = <&cru SCLK_SFC>, <&cru HCLK_SFC>; + clock-names = "clk_sfc", "hclk_sfc"; + pinctrl-0 = <&sfc_clk &sfc_cs &sfc_bus2>; + pinctrl-names = "default"; + power-domains = <&power PX30_PD_MMC_NAND>; + #address-cells = <1>; + #size-cells = <0>; + + flash@0 { + compatible = "jedec,spi-nor"; + reg = <0>; + spi-max-frequency = <108000000>; + spi-rx-bus-width = <2>; + spi-tx-bus-width = <2>; + }; + }; + +...
