From: Simon Horman <horms@verge.net.au> To: linux-arm-kernel@lists.infradead.org Subject: [PATCH 3/5] ARM: mach-shmobile: sh73a0: Initialise MMCIF using DT Date: Fri, 30 Nov 2012 08:44:43 +0000 [thread overview] Message-ID: <1354265085-2444-4-git-send-email-horms@verge.net.au> (raw) In-Reply-To: <1354265085-2444-1-git-send-email-horms@verge.net.au> From: Simon Horman <horms+renesas@verge.net.au> This device also requires a voltage regulator which should be defined in a board-specific maner. An example dts snipped follows. / { fixedregulator1v8: fixedregulator@0 { compatible = "regulator-fixed"; regulator-name = "fixed-1.8V"; regulator-min-microvolt = <1800000>; regulator-max-microvolt = <1800000>; }; }; &mmcif { vmmc-supply = <&fixedregulator1v8>; vqmmc-supply = <&fixedregulator1v8>; }; Signed-off-by: Simon Horman <horms+renesas@verge.net.au> --- v2 * Removed SDHI intitialisation as the driver needs updating first * Moved MMC DT from sh73a0.dtsi to sh73a0-reference.dtsi as it is not appropriate for use by sh73a0-kzm9g.dts yet. This is because sh73a0-kzm9g.dts and board-kzm9g.c use both the GIC and INTC interrupt controllers to provide access to a rich set of devices. This is achieved by initilising the interrupt controllers using C code. Work on allowing the INC controller to be initialised using DT is in progress, however, until that is complete only GIC may be initialised using DT. * Add extra entries to clock-sh73a0.c:lookups[] and remove auxdata. Ultimtely the clocks will be described in DT, but the code isn't there yet. --- arch/arm/boot/dts/sh73a0-reference.dtsi | 24 ++++++++++++++++++++++++ arch/arm/mach-shmobile/clock-sh73a0.c | 1 + 2 files changed, 25 insertions(+) create mode 100644 arch/arm/boot/dts/sh73a0-reference.dtsi diff --git a/arch/arm/boot/dts/sh73a0-reference.dtsi b/arch/arm/boot/dts/sh73a0-reference.dtsi new file mode 100644 index 0000000..d4bb012 --- /dev/null +++ b/arch/arm/boot/dts/sh73a0-reference.dtsi @@ -0,0 +1,24 @@ +/* + * Device Tree Source for the SH73A0 SoC + * + * Copyright (C) 2012 Renesas Solutions Corp. + * + * This file is licensed under the terms of the GNU General Public License + * version 2.
