This add the big endianness support for the FTM PWM driver, which will run on LS1 SoC.
Now for the following scenarios: SoC | CPU | FTM-PWM | 'big-endian' property is needed? ---------|--------|---------|--------------------------------- Vybird | LE | LE | No LS1 | LE | BE | Yes LS2 | LE | LE | No Signed-off-by: Xiubo Li <li.xi...@freescale.com> --- drivers/pwm/pwm-fsl-ftm.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/drivers/pwm/pwm-fsl-ftm.c b/drivers/pwm/pwm-fsl-ftm.c index 5d999c1..9a82741 100644 --- a/drivers/pwm/pwm-fsl-ftm.c +++ b/drivers/pwm/pwm-fsl-ftm.c @@ -409,6 +409,7 @@ static struct regmap_config fsl_pwm_regmap_config = { static int fsl_pwm_probe(struct platform_device *pdev) { + struct device_node *np = pdev->dev.of_node; struct fsl_pwm_chip *fpc; struct resource *res; void __iomem *base; @@ -422,6 +423,11 @@ static int fsl_pwm_probe(struct platform_device *pdev) fpc->chip.dev = &pdev->dev; + if (of_property_read_bool(np, "big-endian")) + fsl_pwm_regmap_config.val_format_endian = REGMAP_ENDIAN_BIG; + else + fsl_pwm_regmap_config.val_format_endian = REGMAP_ENDIAN_NATIVE; + res = platform_get_resource(pdev, IORESOURCE_MEM, 0); base = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(base)) -- 1.8.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
