* [PATCH v6 3/3] ARM: dts: stm32: add initial support for stm32mp157-odyssey board @ 2020-07-31 14:30 ` Marcin Sloniewski 0 siblings, 0 replies; 8+ messages in thread From: Marcin Sloniewski @ 2020-07-31 14:30 UTC (permalink / raw) To: linux-arm-kernel Cc: robh+dt, mcoquelin.stm32, alexandre.torgue, mani, a.fatoum, marcin.sloniewski, sam, linus.walleij, stephan, heiko.stuebner, lkundrak, broonie, allen.chen, robh, devicetree, linux-stm32, linux-kernel Add support for Seeed Studio's stm32mp157c odyssey board. Board consists of SoM with stm32mp157c with 4GB eMMC and 512 MB DDR3 RAM and carrier board with USB and ETH interfaces, SD card connector, wifi and BT chip AP6236. In this patch only basic kernel boot is supported and interfacing SD card and on-board eMMC. Signed-off-by: Marcin Sloniewski <marcin.sloniewski@gmail.com> --- Changes in v6: - add reset pin for eth phy - move pinctrl for sdmmc2 to stm32mp15-pinctrl.dtsi Changes in v5: - fix schema for board's dts Changes in v4: - add seeed,stm32mp157c-odyssey-som in compatible for carrier board - fix sdmmc2 interface by changing one of the pins to use - change eth phy address to 7 Changes in v3: - fix compilation on tip of stm32-next due to change in names for pinctrl - fix deprecated binding for led node - fix redundant "okay" statuses - add phy part number for eth in comment Changes in v2: - add new odyssey dts to Makefile arch/arm/boot/dts/Makefile | 3 +- arch/arm/boot/dts/stm32mp15-pinctrl.dtsi | 18 ++ .../arm/boot/dts/stm32mp157c-odyssey-som.dtsi | 276 ++++++++++++++++++ arch/arm/boot/dts/stm32mp157c-odyssey.dts | 76 +++++ 4 files changed, 372 insertions(+), 1 deletion(-) create mode 100644 arch/arm/boot/dts/stm32mp157c-odyssey-som.dtsi create mode 100644 arch/arm/boot/dts/stm32mp157c-odyssey.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index e6a1cac0bfc7..a3ea2301c82c 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -1047,7 +1047,8 @@ dtb-$(CONFIG_ARCH_STM32) += \ stm32mp157c-dk2.dtb \ stm32mp157c-ed1.dtb \ stm32mp157c-ev1.dtb \ - stm32mp157c-lxa-mc1.dtb + stm32mp157c-lxa-mc1.dtb \ + stm32mp157c-odyssey.dtb dtb-$(CONFIG_MACH_SUN4I) += \ sun4i-a10-a1000.dtb \ sun4i-a10-ba10-tvbox.dtb \ diff --git a/arch/arm/boot/dts/stm32mp15-pinctrl.dtsi b/arch/arm/boot/dts/stm32mp15-pinctrl.dtsi index b5a66429670c..a47eaecbde42 100644 --- a/arch/arm/boot/dts/stm32mp15-pinctrl.dtsi +++ b/arch/arm/boot/dts/stm32mp15-pinctrl.dtsi @@ -1437,6 +1437,24 @@ pins { };
