Reviewed-by: Sam Protsenko Reviewed-by: Peter Griffin Signed-off-by: Tudor Ambarus Reviewed-by: Rob Herring --- v3: - rename the clock names to just "bus" and "ip" as per Rob's suggestion - collect Peter's R-b tag v2: - fix comments as per Sam's suggestion and collect his R-b tag - Rob's suggestion of renaming the clock-names to just "bus" and "ip" was not implemented as I felt it affects readability in the driver and consistency with other exynos clock drivers. I will happily update the names in the -rc phase if someone else has a stronger opinion than mine. .../bindings/clock/google,gs101-clock.yaml | 25 +++++- include/dt-bindings/clock/google,gs101.h | 81

If using 8-bit register accesses, a SError Interrupt is raised causing the system unusable. Instead of specifying the reg-io-width = 4 everywhere, for each node, the requirement should be deduced from the compatible. Prepare the samsung tty driver to allow IO types different than UPIO_MEM. ``struct uart_port::iotype`` is an unsigned char where all its 8 bits are exposed to uapi. We can't make NULL checks on it to verify if it's set, thus always set it from the driver's data.

Instead of specifying the reg-io-width = 4 everywhere, for each node, the requirement should be deduced from the compatible. Infer UPIO_MEM32 iotype from the "google,gs101-uart" compatible. Update the uart info name to be GS101 specific in order to differentiate from the other exynos platforms. All the other settings are not changed. exynos_fifoszdt_serial_drv_data was replaced by gs101_serial_drv_data because the iotype restriction is gs101 specific and there was no other user of exynos_fifoszdt_serial_drv_data.

Define USI8 in I2C configuration. USI8 CONFIG register comes with a 0x0 reset value, meaning that USI8 doesn't have a default protocol (I2C, SPI, UART) at reset. Thus the selection of the protocol is intentionally left for the board dts file. Signed-off-by: Tudor Ambarus Reviewed-by: Sam Protsenko --- v3: reorder usi8 clock order (thanks Andre'!). Did not make any difference at testing as the usi driver treats the clocks in bulk. v2: - identify and use gate clocks instead of dividers - move cells and pinctrl properties from dts to dtsi - move IRQ type constant on the previous line arch/arm64/boot/dts/exynos/google/gs101.dtsi | 29 ++++++++++++++++++++ 1 file changed, 29 insertions(+) diff --git a/arch/arm64/boot/dts/exynos/google/gs101.dtsi b/arch/arm64/boot/dts/exynos/google/gs101.dtsi index 6aa25cc4676e..f14a24628d04 100644 --- a/arch/arm64/boot/dts/exynos/google/gs101.dtsi +++ b/arch/arm64/boot/dts/exynos/google/gs101.dtsi @@ -352,6 +352,35 @@ pinctrl_peric0: pinctrl@10840000 { interrupts = ; }; + usi8: usi@109700c0 { + compatible = "google,gs101-usi", + "samsung,exynos850-usi"; + reg = <0x109700c0 0x20>; + ranges; + #address-cells = <1>; + #size-cells = <1>; + clocks = <&cmu_peric0 CLK_GOUT_PERIC0_CLK_PERIC0_USI8_USI_CLK>, + <&cmu_peric0 CLK_GOUT_PERIC0_PERIC0_TOP0_IPCLK_7>; + clock-names = "pclk", "ipclk"; + samsung,sysreg = <&sysreg_peric0 0x101c>; + status = "disabled"; + + hsi2c_8: i2c@10970000 { + compatible = "google,gs101-hsi2c", + "samsung,exynosautov9-hsi2c"; + reg = <0x10970000 0xc0>; + interrupts = ; + #address-cells = <1>; + #size-cells = <0>; + pinctrl-names = "default"; + pinctrl-0 = <&hsi2c8_bus>; + clocks = <&cmu_peric0 CLK_GOUT_PERIC0_PERIC0_TOP0_IPCLK_7>, + <&cmu_peric0 CLK_GOUT_PERIC0_CLK_PERIC0_USI8_USI_CLK>; + clock-names = "hsi2c", "hsi2c_pclk"; + status = "disabled"; + }; + }; + usi_uart: usi@10a000c0 { compatible = "google,gs101-usi", "samsung,exynos850-usi"; From patchwork Tue Jan 9 12:58:14 2024 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit X-Patchwork-Submitter: Tudor Ambarus X-Patchwork-Id: 762424 Received: from mail-wm1-f51.google.com (mail-wm1-f51.google.com [209.85.128.51]) (using TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits)) (No client certificate requested) by smtp.subspace.kernel.org (Postfix) with ESMTPS id 101533B292 for ; Tue, 9 Jan 2024 12:58:47 +0000 (UTC) Authentication-Results: smtp.subspace.kernel.org; dmarc=pass (p=none dis=none) header.from=linaro.org Authentication-Results: smtp.subspace.kernel.org; spf=pass smtp.mailfrom=linaro.org Authentication-Results: smtp.subspace.kernel.org; dkim=pass (2048-bit key) header.d=linaro.org header.i=@linaro.org header.b="jvboTT8H" Received: by mail-wm1-f51.google.com with SMTP id 5b1f17b1804b1-40e4d1e0e5eso8582155e9.3 for ; Tue, 09 Jan 2024 04:58:47 -0800 (PST) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=linaro.org; s=google; t=1704805126; x=1705409926; darn=vger.kernel.org; h=content-transfer-encoding:mime-version:references:in-reply-to :message-id:date:subject:cc:to:from:from:to:cc:subject:date :message-id:reply-to; bh=66WHfoChmjF44TpuZe1F+scHybHenf1Nb7ZkRVtSfIY=; b=jvboTT8HDIIbPBJx1k1H6z2qsvXcBmMSE75MdksfIdcMvurkDML9c3BrdRy6wKiYf4 37Yl0qte142lNSU0zGWV4AQR6d+UaRSmHa9UINdfrRy8ecbSoFnXJ4MLRZDxjV7TVHZh HjhdkkyXozC78rPMvPTIJdVCa0t9olnBOzYcIOQ/WaesBxn9vErQaOmLXxsY2fpO9PBI nCGTfIsMjxzoSZhk9LvgseeJElpXgCP34aPrS+BvZvFpofmXzE+fYYEyFziS7J0j/3gL NzXmw2gSJhoKuN/5UzNrJAvO45A+wHz3xQ7xnfVe6b2pSh7rKSyiC7s4GLp6UV9BgM64 WOxg== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20230601; t=1704805126; x=1705409926; h=content-transfer-encoding:mime-version:references:in-reply-to :message-id:date:subject:cc:to:from:x-gm-message-state:from:to:cc :subject:date:message-id:reply-to; bh=66WHfoChmjF44TpuZe1F+scHybHenf1Nb7ZkRVtSfIY=; b=Tc/vH3/Sk0Be6tE8QcDMX3gtFAJctKuj89amRPK2zeHluRT/prWyeVeQJYOzIWhzYd Zgjg10he/Rwc9ZsFnw+W57kIrKexwOxUapUQX2UZJj5TPkPYNg21JfFXkcCGS8ApQKoq c2HMbLiNN6pJMxMsQoaM6B9xqL+YapqIUtsoNc+Ep1i4+eAxQMgetXcsVPuJZnj16NYP EnblW0JLPaoJSkuLsQ5B1HROhGpoIQnlHJreq8N3rBUVhScszsG8F3EcQYKT5ZDA65dY 2mSjjv4WJAObrQ2mi9gISZWOE/paIlrbCsoi3Y1Zd9rYBkENV5ig41rI7Yg8l2mjvlxO 706w== X-Gm-Message-State: AOJu0YxE6flrepCXeD3Q+NkxsgIZCVaYOsIWWMS8Kfo2XqjIHZ2ZDmHV NDwCJXcdQJg7KTkYPeWoAtP4/amXGhzuxg== X-Google-Smtp-Source: AGHT+IHTeV8EyfLOccPihdbXSpbOQ08P0ffNZMnT6S1UpNLyuVQRXyqsi0Qq1eRPCQMkBY5K2Eql1A== X-Received: by 2002:a05:600c:538d:b0:40e:41f2:6d74 with SMTP id hg13-20020a05600c538d00b0040e41f26d74mr2481510wmb.67.1704805126502; Tue, 09 Jan 2024 04:58:46 -0800 (PST) Received: from ta2.c.googlers.com.com (88.140.78.34.bc.googleusercontent.com.
