From: Stephen Warren <[email protected]> Tegra's clock driver now provides an implementation of the common reset API (include/linux/reset.h). Use this instead of the old Tegra- specific API; that will soon be removed.

I'm looking for an ack so that I can take the entire series through the Tegra and arm-soc trees. The series will be part of a stable branch that can be merged into other subsystems if needed to avoid/resolve dependencies. --- drivers/i2c/busses/i2c-tegra.c | 13 ++++++++++--- 1 file changed, 10 insertions(+), 3 deletions(-) diff --git a/drivers/i2c/busses/i2c-tegra.c b/drivers/i2c/busses/i2c-tegra.c index e661edee4d0c..9704537aee3c 100644 --- a/drivers/i2c/busses/i2c-tegra.c +++ b/drivers/i2c/busses/i2c-tegra.c @@ -27,7 +27,7 @@ #include <linux/slab.h> #include <linux/of_device.h> #include <linux/module.h> -#include <linux/clk/tegra.h> +#include <linux/reset.h> #include <asm/unaligned.h> @@ -160,6 +160,7 @@ struct tegra_i2c_dev { struct i2c_adapter adapter; struct clk *div_clk; struct clk *fast_clk; + struct reset_control *rst; void __iomem *base; int cont_id; int irq; @@ -415,9 +416,9 @@ static int tegra_i2c_init(struct tegra_i2c_dev *i2c_dev) return err; } - tegra_periph_reset_assert(i2c_dev->div_clk); + reset_control_assert(i2c_dev->rst); udelay(2); - tegra_periph_reset_deassert(i2c_dev->div_clk); + reset_control_deassert(i2c_dev->rst); if (i2c_dev->is_dvc) tegra_dvc_init(i2c_dev); @@ -743,6 +744,12 @@ static int tegra_i2c_probe(struct platform_device *pdev) i2c_dev->cont_id = pdev->id; i2c_dev->dev = &pdev->dev; + i2c_dev->rst = devm_reset_control_get(&pdev->dev, "i2c"); + if (IS_ERR(i2c_dev->rst)) { + dev_err(&pdev->dev, "missing controller reset"); + return PTR_ERR(i2c_dev->rst); + } + ret = of_property_read_u32(i2c_dev->dev->of_node, "clock-frequency", &i2c_dev->bus_clk_rate); if (ret) -- 1.8.1.5 -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
