Date: Mon, 27 Jun 2022 20:39:56 +0100 Message-Id: <20220627194003.2395484-9-mail@conchuod.ie> X-Mailer: git-send-email 2.36.1 In-Reply-To: <20220627194003.2395484-1-mail@conchuod.ie> References: <20220627194003.2395484-1-mail@conchuod.ie> MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: dmaengine@vger.kernel.org From: Conor Dooley The k210 U-Boot port has been using the clocks defined in the devicetree to bring up the board's SRAM, but this violates the dt-schema. As such, move the clocks to a dedicated node with the same compatible string. The regs property does not fit in either node, so is replaced by comments. Signed-off-by: Conor Dooley --- The corresponding U-Boot code seems to be: static int sram_init(void) { int ret, i; const char * const banks[] = { "sram0", "sram1", "aisram" }; ofnode memory; struct clk clk; /* Enable RAM clocks */ memory = ofnode_by_compatible(ofnode_null(), "canaan,k210-sram"); if (ofnode_equal(memory, ofnode_null())) return -ENOENT; for (i = 0; i < ARRAY_SIZE(banks); i++) { ret = clk_get_by_name_nodev(memory, banks[i], &clk); if (ret) continue; ret = clk_enable(&clk); clk_free(&clk); if (ret) return ret; } return 0; } Which, without having the hardware etc, I suspect is likely to keep working after the move. --- arch/riscv/boot/dts/canaan/k210.dtsi | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) diff --git a/arch/riscv/boot/dts/canaan/k210.dtsi b/arch/riscv/boot/dts/canaan/k210.dtsi index 44d338514761..cd4eae82d8b2 100644 --- a/arch/riscv/boot/dts/canaan/k210.dtsi +++ b/arch/riscv/boot/dts/canaan/k210.dtsi @@ -69,11 +69,13 @@ cpu1_intc: interrupt-controller { sram: memory@80000000 { device_type = "memory"; + reg = <0x80000000 0x400000>, /* sram0 4 MiB */ + <0x80400000 0x200000>, /* sram1 2 MiB */ + <0x80600000 0x200000>; /* aisram 2 MiB */ + }; + + sram_controller: memory-controller { compatible = "canaan,k210-sram"; - reg = <0x80000000 0x400000>, - <0x80400000 0x200000>, - <0x80600000 0x200000>; - reg-names = "sram0", "sram1", "aisram"; clocks = <&sysclk K210_CLK_SRAM0>, <&sysclk K210_CLK_SRAM1>, <&sysclk K210_CLK_AI>;
