From 95ca100ba740283e00f0b5354be8ccb04b97cbf9 Mon Sep 17 00:00:00 2001 From: Kever Yang Date: Thu, 27 Jul 2017 12:54:00 +0800 Subject: [PATCH] rockchip: rk322x: update max-frequency for mmc node mmc using 150000000 as max-frequency like what rk3288 sets. This can speed up the mmc read/write, the actual mmc clock is: Before this patch: 37.125M After this patch: 49.5M Signed-off-by: Kever Yang Reviewed-by: Philipp Tomsich Acked-by: Philipp Tomsich --- arch/arm/dts/rk3229-evb.dts | 1 - arch/arm/dts/rk322x.dtsi | 4 ++-- 2 files changed, 2 insertions(+), 3 deletions(-) diff --git a/arch/arm/dts/rk3229-evb.dts b/arch/arm/dts/rk3229-evb.dts index e066a306d0..64f1c2d7da 100644 --- a/arch/arm/dts/rk3229-evb.dts +++ b/arch/arm/dts/rk3229-evb.dts @@ -79,7 +79,6 @@ cap-sd-highspeed; card-detect-delay = <200>; disable-wp; - max-frequency = <50000000>; num-slots = <1>; supports-sd; }; diff --git a/arch/arm/dts/rk322x.dtsi b/arch/arm/dts/rk322x.dtsi index ddbe113741..22324f97b3 100644 --- a/arch/arm/dts/rk322x.dtsi +++ b/arch/arm/dts/rk322x.dtsi @@ -388,6 +388,7 @@ sdmmc: dwmmc@30000000 { compatible = "rockchip,rk3228-dw-mshc", "rockchip,rk3288-dw-mshc"; reg = <0x30000000 0x4000>; + max-frequency = <150000000>; interrupts = ; clocks = <&cru HCLK_SDMMC>, <&cru SCLK_SDMMC>, <&cru SCLK_SDMMC_DRV>, <&cru SCLK_SDMMC_SAMPLE>; @@ -414,9 +415,8 @@ emmc: dwmmc@30020000 { compatible = "rockchip,rk3288-dw-mshc"; reg = <0x30020000 0x4000>; + max-frequency = <150000000>; interrupts = ; - clock-frequency = <37500000>; - max-frequency = <37500000>; clocks = <&cru HCLK_EMMC>, <&cru SCLK_EMMC>, <&cru SCLK_EMMC_DRV>, <&cru SCLK_EMMC_SAMPLE>; clock-names = "biu", "ciu", "ciu_drv", "ciu_sample"; -- 2.39.5
