From mboxrd@z Thu Jan 1 00:00:00 1970 From: linus.walleij@linaro.org (Linus Walleij) Date: Wed, 24 May 2017 11:07:48 +0200 Subject: [PATCH] ARM: dts: augment Moxa and Aspeed DTS for FTTMR010 Message-ID: <20170524090748.27345-1-linus.walleij@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This augments the Moxa Art and Aspeed device trees to: - Explicitly name the clock "PCLK" as the Faraday FTTMR010 names it. - List the Moxa timer as compatible with the Faradat FTTMR010 vanilla version. - Add a comment that the Aspeed driver is a Faraday FTTMR010 derivative. - Pass all IRQs to the timer from Aspeed: they are all there so they should be in the device tree, we only use the first one anyways. Tested-by: Joel Stanley Tested-by: Jonas Jensen Signed-off-by: Linus Walleij --- ARM SoC maintainers: this is the DTS changes needt to generalize the Faraday timer. Please merge this into some suitable ARM SoC DTS branch. Clocksource maintainers: I will ask the ARM SoC people to merge this patch orthogonally, it is only included in this series for reference and for testing. --- arch/arm/boot/dts/aspeed-g4.dtsi | 7 +++---- arch/arm/boot/dts/aspeed-g5.dtsi | 7 +++---- arch/arm/boot/dts/moxart.dtsi | 3 ++- 3 files changed, 8 insertions(+), 9 deletions(-) diff --git a/arch/arm/boot/dts/aspeed-g4.dtsi b/arch/arm/boot/dts/aspeed-g4.dtsi index 8c6bc29eb7f6..8a04c7e2d818 100644 --- a/arch/arm/boot/dts/aspeed-g4.dtsi +++ b/arch/arm/boot/dts/aspeed-g4.dtsi @@ -886,13 +886,12 @@ }; timer: timer at 1e782000 { + /* This timer is a Faraday FTTMR010 derivative */ compatible = "aspeed,ast2400-timer"; reg = <0x1e782000 0x90>; - // The moxart_timer driver registers only one - // interrupt and assumes it's for timer 1 - //interrupts = <16 17 18 35 36 37 38 39>; - interrupts = <16>; + interrupts = <16 17 18 35 36 37 38 39>; clocks = <&clk_apb>; + clock-names = "PCLK"; }; wdt1: wdt at 1e785000 { diff --git a/arch/arm/boot/dts/aspeed-g5.dtsi b/arch/arm/boot/dts/aspeed-g5.dtsi index a0bea4a6ec77..9cffe347b828 100644 --- a/arch/arm/boot/dts/aspeed-g5.dtsi +++ b/arch/arm/boot/dts/aspeed-g5.dtsi @@ -993,13 +993,12 @@ }; timer: timer at 1e782000 { + /* This timer is a Faraday FTTMR010 derivative */ compatible = "aspeed,ast2400-timer"; reg = <0x1e782000 0x90>; - // The moxart_timer driver registers only one - // interrupt and assumes it's for timer 1 - //interrupts = <16 17 18 35 36 37 38 39>; - interrupts = <16>; + interrupts = <16 17 18 35 36 37 38 39>; clocks = <&clk_apb>; + clock-names = "PCLK"; }; diff --git a/arch/arm/boot/dts/moxart.dtsi b/arch/arm/boot/dts/moxart.dtsi index e86f8c905ac5..1f4c795d3f72 100644 --- a/arch/arm/boot/dts/moxart.dtsi +++ b/arch/arm/boot/dts/moxart.dtsi @@ -58,10 +58,11 @@ }; timer: timer at 98400000 { - compatible = "moxa,moxart-timer"; + compatible = "moxa,moxart-timer", "faraday,fttmr010"; reg = <0x98400000 0x42>; interrupts = <19 IRQ_TYPE_EDGE_FALLING>; clocks = <&clk_apb>; + clock-names = "PCLK"; }; gpio: gpio at 98700000 { -- 2.9.4
